The invention relates to the technical fields of stepless speed regulation and power load adaptation in rotary power and load systems thereof (such as fans, pumps, various transportation means, various mechanical equipment and the like), a power dividing/converging device, a two-way/multi-stage power allocation device, an energy recovery device and the like, in particular to a power regulation/speed regulator and a super energy-saving system thereof, which integrate a part of or all functions of stepless speed regulation, torque conversion, energy recovery, power mixing, distributed power allocation, power stepless allocation and the like, and particularly relates to a stepless speed regulator and a super energy-saving system thereof based on a differential transmission/power converging mechanism.

Background

In more than ten years, the fast-developed permanent magnet coupling speed regulator is also gradually accepted by experts and markets in the field of centrifugal load speed regulation, energy conservation and emission reduction, but has obvious defects and shortcomings. The invention patent in the aspect of the permanent magnet coupling speed regulator is successively authorized by the inventor since 2009, and self-funding and factory building are carried out, mass production is formed, the energy saving and emission reduction aspects of an industrial centrifugal load system (a fan, a water pump and the like) are widely applied and well evaluated, the energy saving technology level is greatly improved, the permanent magnet coupling speed regulator is gradually realized in the popularization process, but the defects that the average practical working efficiency of the power load system is generally lower than 60 percent, particularly the large-power model is overcome, the cooling device is added in the system because the main disc and the driven disc are of an air gap coupling cantilever beam structure and are limited by the design of the axial installation size of equipment, severe vibration and noise are necessarily generated under the working condition of high power or/and high rotating speed, the system reliability is poor, the system efficiency is low, particularly under the working condition of low rated rotating speed, high power and high reducing speed, the energy proportional to the percent of the reducing speed is changed into a large quantity of heat consumed on a metal conductor disc, the average practical working efficiency of the power load system is generally lower than 60 percent, the cooling device is additionally arranged in the system, the speed is greatly increased, the speed is greatly reduced along with the speed increasing precision and the speed is not limited by the self-locking function, and the speed is greatly limited by the speed regulating function, and the speed is not limited by the speed regulating shaft.

The high-voltage high-power motor frequency converter has many applications in the field of energy conservation and emission reduction of a centrifugal load system, but has the defects of large occupied space, poor reliability, high self energy consumption, obvious reduction of average actual working total effective efficiency of the power load system in most frequency bands compared with rated efficiency, generally lower than 60 percent due to the restriction of the working efficiency characteristic, serious electric harmonic pollution of the frequency converter, high-voltage frequency converter equipment price, special maintenance requirement, huge running cost and the like due to the high requirement on the running environment.

The hydraulic coupling speed regulator is widely arranged in an adjustable centrifugal load system and a non-centrifugal load system (such as a fan, a water pump, a ball mill, a feeder, a conveyor belt, a development machine, a drilling machine, a lifter, an air compressor and the like), and has lower efficiency compared with the average actual working total effective efficiency of the power load system, smaller speed regulation range, large consumption of hydraulic medium consumption, environmental pollution and other reasons, and the technology is more lagging behind.

On the one hand, the energy-saving technology of the traditional speed regulator is only suitable for a 'large maraca' system, is unfavorable for improving the system efficiency and causes resource allocation waste, on the other hand, in the process of regulating the load speed reduction of a high-power system, only the power consumed by the load can be reduced, the output efficiency of the power system can not be improved, and the working efficiency of the power system can be greatly reduced, so that the system consumes energy and generates heat seriously, the heat is difficult to recycle, and the system is required to be provided with a cooling device, so that the cost input is greatly increased, and meanwhile, the reliability of the system is also obviously reduced. In other words, for the current large-scale power load system, especially for centrifugal equipment such as a large-scale fan water pump, even if energy-saving equipment such as a frequency converter, a permanent magnet speed regulator, a fluid coupler and the like is installed, the average actual working total effective efficiency of the power load system is generally not more than 65%, even lower, and the waste is huge. In addition, the common power and load system has the problem of matching the power and the load, and serious energy or power waste phenomenon can be caused. Therefore, in order to solve the long-standing problem of "old and difficult" in the technical field of energy conservation and emission reduction, the traditional speed regulation/speed change product and the energy conservation and emission reduction technology thereof are urgently required to be innovated, the existing "pain points" are comprehensively formulated, and the development and production of a new generation of stepless speed regulator based on a differential transmission/power confluence mechanism and a stepless speed regulator based on the differential transmission/power confluence mechanism and an energy saving system thereof are very necessary.

On one hand, the invention not only comprises the technical proposal of various configurations taking full power as the idea of power configuration with less consumption for feet and more recovery; on the other hand, the invention also comprises a plurality of technical schemes with different configurations, which are constructed by taking the more innovative energy-saving concept of 'how much and how much to be needed and how much to be wasted' as the functional aim, so as to abandon the traditional power configuration scheme that the traditional scheme that the rated power of a power source is more than or equal to the rated power of a load (15-20% of the redundancy coefficient of the power required by the cold start of a system) is required to meet the requirement that the rated power of a large maraca car is more than or equal to the rated power of the load, and establish an innovative energy-saving power load configuration scheme that the rated power of a main power source is more than or equal to the rated power of a power regulating motor. In conclusion, the invention provides a new and perfect technical scheme for energy conservation and emission reduction, and is possible to construct an intelligent power load system with super energy conservation.

The intelligent, multifunctional and innovative performance is realized in the following aspects that firstly, a main power source is firstly not operated in the starting process, and a power adjusting/speed regulating motor is firstly operated to realize the load soft starting function; secondly, the output rotating speed and torque of the power regulating/speed regulating motor are controlled in the normal working process of the power load system, the aim of regulating the load rotating speed and power is achieved through the power converging mechanism, so that the problems that the system efficiency and serious energy consumption are reduced due to the fact that the speed reduction generated by the traditional energy saving technology is applied to the constant rotating speed power system are solved, thirdly, particularly in a variable frequency energy saving system of a high-voltage high-power load, as the power regulating/speed regulating motor can select a voltage grade and a smaller power model which are different from those of a main power source, the power regulating/speed regulating motor with high reliability and low cost and a frequency converter thereof are more convenient to use, the energy saving transformation of the traditional high-voltage high-power motor system is more easily and more intensively constructed, fourthly, distributed hybrid power can be adopted, a power allocation scheme for replacing a main power source for the large-sized load is adopted, the power supply is more diversified, the improvement of the power supply, the safety and the reliability are more favorable, and the five power regulating/speed regulating motor is more convenient, and the power efficiency is more convenient than the power supply is obviously reduced under the power output condition of the power regulating mode of the power source (the power regulating/speed regulating motor is more than the rated power source is in general power output power-efficient and the power-reducing working condition of the power-efficient and the power-saving power system is greatly reduced in the power-rated power output working condition of the power condition of the invention, the high-efficiency operation of the power equipment under the all-weather working condition is possible; sixthly, in various life fields of industrial and agricultural production and society, the invention has the energy-saving field of large and medium-sized centrifugal equipment (such as fans, pumps and the like), and the technical scheme of the invention can improve the total energy-saving efficiency of the system by at least more than 30 percent, thereby having wide application space and market prospect. The speed regulator based on the planetary gear set power converging mechanism provides important technical support in the aspect of energy conservation for constructing a super energy-saving power load system according to the minimum energy consumption principle, the lever principle, the gear transmission principle and the energy conservation principle. It should be noted that the power types of the main power source described below are various, and any rotary power source may be used, such as an electric motor, an internal combustion engine, a steam turbine, a water turbine, etc., and it is needless to say that the main power source may be the same type as the power adjusting/speed adjusting motor in some application conditions, and as a result of such selection, maintenance and emergency replacement of the apparatus are more convenient, or the time-sharing/combination control between the main power source power adjusting/speed adjusting motor and the power adjusting/speed adjusting motor is controlled by a common control driver/frequency converter by controlling the control switch device, so that a combination control and control switch function adapted to special requirements is conveniently established.

In the application scene of power load equipment in the fields of social life and industrial and agricultural production, a specific speed regulation range can be designed and determined according to different working conditions and process requirements, and a common configuration scheme of a main power source and a power regulation/speed regulation motor and a working module/mode list thereof are as follows, so that a system can call and operate in real time:

To meet primary power source power rating + power regulation rated power of speed-regulating motor not less than rated load power

Rated power of main power source is not less than K% of the load rated shaft power,

Wherein K <50 to 100 is optional, generally preferably 60 to 75;

the corresponding number of the corresponding numbers is that, the rated power of the power adjusting/speed regulating motor is equal to or more than (1-K) the rated shaft power of the load:

Soft start & stepless speed/power regulation range 1 from 0% to K%;

Stepless speed increasing/power regulating range 2 from K% to 100%;

stepless speed reduction/power regulation ranges from K% to 0%.

① The soft start module, the speed regulator works under the state of 'soft start & stepless regulation range 1', before the main power source is put into operation, the power regulation/speed regulation motor is started to work, the output of the motor is enabled to be from small to large positive torque, the load is driven to start slowly, then the main power source is started again, the load rotating speed is enabled to start smoothly from low to high, the speed is transited to normal operation, the extra-ordinary multiple starting power required when the load starts rapidly can be greatly reduced, and especially for a high-speed large-inertia high-power load system, the rapid start of the system often fails, and even power equipment is burnt, so the soft start module is very necessary.

② The heat engine/light load module, the speed regulator works under "after soft start" state, the power load system sometimes needs the load equipment to be in the idle operation of the low-rotation speed (light load) heat engine, namely the main power source is not started, the load is in the separated/no-load/light load state, the power adjusting/speed regulating motor continuously works and outputs positive torque, and the driving load is idle operation at a load rotation speed less than or equal to the rated power of the power adjusting/speed regulating motor.

③ In general, in order to comprehensively combine the factors of small system construction investment and good energy-saving effect, the rated power and the rotating speed of the main power source are determined according to the most basic load shaft power and the rotating speed in the most common load working condition/process, at this time, the power adjusting/speed regulating motor is in a static state or the transmission shaft is in a '0 rotating speed and large torque' braking state, no adjusting power is output, the main power source is only used for working, the rated power and the rotating speed are output, and the load is maintained to work in the rated power and rotating speed state of the most basic (concurrently or minimum) and most common working condition/process.

④ The stepless speed increasing/power regulating and increasing operation mode is that only the normal rated power of the main power source can not meet the requirement of increasing the power/rotating speed of a working condition load, the power regulating/speed regulating motor is arranged in a motor working state, namely the power regulating/speed regulating motor is put into operation and outputs positive torque (torque in the same direction with the positive rotating speed of the load), the output power/torque of the power regulating/speed regulating motor is regulated in real time according to the working condition requirement, and the load equipment is driven to work by the power confluence of the stepless speed regulator based on the differential transmission/power confluence mechanism and the common output force until the rated power/torque of the main power source and the rated power/torque of the power regulating/speed regulating motor are more than or equal to the rated shaft power/torque of the load. When the system works in a stepless speed increasing adjusting range 2 state, the main power source operates at rated power and rotating speed, the power adjusting/speed regulating motor operates at the power and torque/rotating speed which are set by controlling and adjusting, the sum of the power and the power is equal to the load shaft power under real-time working conditions, and the power adjusting/speed regulating motor is controlled to output the adaptive power and rotating speed according to the working condition process requirements, so that the aims of driving the load power 'how much and no waste' are achieved. At this time, the main power source and the power adjusting/speed regulating motor drive the planetary gears to rotate and revolve through the power input end/shaft and the power adjusting end/shaft of the speed regulator respectively, the rotation torque and the revolution torque of the planetary gears are superposed on the power output end/shaft of the speed regulator in the same direction, namely, the output power of the main power source and the power adjusting/speed regulating motor is converged to the output end/shaft of the speed regulator, so that the work-doing operation of the load can be driven by two or more distributed power resultant forces (multi-stage series connection).

⑤ In a deceleration/emergency regulation operation mode, namely a non-electric power recovery deceleration operation mode, in general, power braking and deceleration loss exist in the mode, the operation is usually but not limited to an emergency condition, a speed regulator works in a stepless deceleration regulation range 3 state, a main power source operates at a rated rotation speed, when the load rotation speed needs to be in deceleration operation or abnormal emergency load rotation speed requirements under special working condition process conditions are met, a power regulation/speed regulation motor is started to be arranged at negative torque (torque opposite to positive rotation acting direction of the load driven by the power regulation/speed regulation motor), namely, the main power source operates at the rated rotation speed, the power regulation/speed regulation motor is controlled to operate with reverse braking power and torque/rotation speed input, the difference of the power regulation/speed regulation motor is equal to load shaft power under emergency real-time working condition process conditions, the power regulation/speed regulation motor outputs adaptive braking power according to requirements, the load is driven to be in deceleration operation, and meanwhile, the energy saving effect of load deceleration can be obtained. At this time, the main power source and the power adjusting/speed regulating motor drive the planetary gears to revolve in the opposite direction through the power input end/shaft and the power adjusting end/shaft of the speed regulator respectively, the rotation torque and the revolution torque of the planetary gears are opposite in direction, and the braking torque in the opposite direction is applied to the power output end/shaft of the speed regulator, namely, the difference of the output powers of the main power source and the power adjusting/speed regulating motor is converged to the output end/shaft of the speed regulator so as to meet the load emergency speed reduction operation requirement. The module is only arranged to meet the needs of the special working condition process when the needs occur. The reason is that under this working module, in order to save energy in the system to meet the deceleration conditions for regulating the deceleration flow and pressure, especially for centrifugal loads, the overall energy saving effect is good even if a little of the braking power of the power regulating/speed regulating motor is consumed under this module, since the real-time shaft power of the load is proportional to the cube of the rotational speed. The frequency of operation of the module is reduced, the rated power configuration of the main power source is reduced, the rated power configuration of the power adjusting/speed regulating motor is increased, and if the rated power configuration of the power adjusting/speed regulating motor is increased, the system cost is larger, but the speed regulating range of the normal stepless speed increasing adjusting range 2 which is more energy-saving is larger. According to the equipment configuration principle, the beneficial energy-saving and low-cost factors under various working condition and process conditions are comprehensively considered so as to construct a more reasonable stepless speed regulator.

⑥ Stepless speed reduction/load power regulation and reduction-electric power recovery speed reduction operation mode, wherein the main power source works normally, and the power regulation/speed regulation motor is started to work and output negative torque (torque which is opposite to the positive rotating speed of a load), namely, the power regulation/speed regulation motor works in a generator state and becomes a power regulation generator, the main power source performs power allocation through a stepless speed regulator based on a differential transmission/power convergence mechanism, one part of the main power source output power or torque drives a load device to work at a lower operating rotating speed through a power output end of the stepless speed regulator based on the differential transmission/power convergence mechanism, the other part of the main power source output power or torque is allocated to a power regulation generator through a power regulation end of the stepless speed regulator based on the differential transmission/power convergence mechanism, and the power output of the power regulation/speed regulation motor is fed back to an electric power device through a corresponding loop of a controller to be used, or provides electric power source for an internal/external electric network, or provides power for power storage equipment or other electric loads.

The scheme is based on and utilizes the working mechanism of a planetary gear differential transmission mechanism and a power converging/dividing power transmission mechanism, and the association interaction relation between the differential speed, the power converging/dividing flow and a planet carrier (planetary gear differential shell) of the differential transmission mechanism is deeply excavated by using the minimum energy consumption principle, the lever principle, the gear transmission principle, the energy conservation principle and the regulation type load speed regulation energy-saving principle, so that the functions of three-dimensional energy adaptation, distribution or mutual control are realized, and the new design concepts and functions of the planet carrier, the left half shaft and the right half shaft of the dividing power/differential transmission mechanism are endowed, thereby constructing the stepless speed regulator based on the differential transmission/power converging mechanism with different purposes and functions. In the scheme, the planet carrier, the left half shaft and the right half shaft can be respectively used as a power input end, a power adjusting end or a power splitting/allocating/adapting end, and the difference is that the energy transmission paths are different, and the allocating torque transmission ratio and the rotating speed ratio between the input and the output are different. That is, one of the two left and right half shafts serves as an output end/shaft of the continuously variable governor based on the differential transmission/power confluence mechanism, and the other half shaft and the planetary carrier serve as a main power input end/shaft, and the remaining one serves as a power adjustment end/shaft and is coupled with a rotor/rotor shaft of the power adjustment/governor motor (refer to a motor having a motor/generator function that is bidirectionally controllable on line in real time). The stepless speed regulator based on the differential transmission/power converging mechanism can be used in a single stage, and can be arranged in a multistage series/parallel connection mode so as to input more power sources and be assembled into more flexible, various and powerful working modes.

Detailed Description

Example 1

As shown in fig. 1 and 2, the stepless speed regulator based on differential transmission/power confluence mechanism is an embedded stepless speed regulator based on differential transmission/power confluence mechanism of asymmetric axial cylindrical planetary gears. Differential transmission/power converging mechanism (differential transmission/power converging mechanism is in some common technical fields such as automobile field, or is called differential mechanism and differential mechanism, in the transmission technical field or is called power divider, power converging mechanism, power dividing mechanism, etc. they are in different application fields, their structures are different or different, but their working mechanisms are different) component is integrally embedded in hollow rotor of power regulating/speed regulating motor, it is mainly formed from four axial cylindrical planetary gear (107 and 116) power converging mechanism components (101, 102, 103, 105, etc.), 106. 107 and 116), stator assemblies (120, 121, 122, 123, 124 and 133) and permanent magnet hollow rotor assemblies (130, 131, 132, 113 and 114) of permanent magnet power adjusting/speed regulating motors, speed regulator accessories (126, 110, 115, 125 and 138), adaptive power adjusting/speed regulating motor control drives/vector control type frequency converters and motor speed encoders (not shown) thereof. Wherein, the axial cylindrical planetary gear differential transmission/power combiner component consists of an upper cylindrical planetary gear (107, 116), a lower cylindrical planetary gear (107), a left cylindrical planetary gear (116), a straight pin type planetary gear shaft (105), a planetary gear carrier (101), a left half shaft gear/cylindrical internal tooth gear ring (102) and a right half shaft gear/cylindrical external tooth sun gear (103), the four straight pin type planetary gear shafts (105) are arranged in parallel with the central axes of the left half rotor shaft (109, 129), each cylindrical planetary gear (107 or 116) is meshed with the right half shaft cylindrical external tooth sun gear (103) and the left half shaft cylindrical internal tooth gear ring (102) respectively, the left half shaft (102) is used as a power regulating end of the stepless speed regulator and is connected with a rotor (130) body into a whole structure, the right half shaft (129) is used as a power output end/shaft of the stepless speed regulator, and simultaneously is also used as a right half rotor shaft (129), and an isolating/supporting bearing (115) of the right half rotor end cover (114) and a stator end cover (124) is used, 125 A shafting right half rotor shaft (129) arranged as a hollow rotor of the power adjusting/speed regulating motor, a cylindrical planetary gear carrier (101) used as a power input end of a main power source is connected with a left half rotor shaft (109) in an adapting way by using a shaft key (136), the shafting left half rotor shaft (109) of the permanent magnet hollow rotor (130) of the power adjusting/speed regulating motor is arranged through isolating/supporting bearings (110, 126) of a rotor end cover (113) and a stator end cover (133) which are matched on the left side and extends out of the shaft extension (139) of the power input shaft (109) of which the outer sides of the rotor end cover (113) and the stator end cover (133) are formed into a stepless speed regulator, and other speed regulator accessories comprise a stator shell/body (123), A stator core (121), a stator field winding (122), a rotor permanent magnet assembly (132), a bolt fastener (138), and the like. The power regulation/speed regulation motor control driver/vector control type frequency converter has wide market application, can control the power regulation/speed regulation motor to randomly regulate the rotating speed, can set the power to be output at a constant rotating speed or a constant torque, can set the rotating speed to be output at a variable power or a variable torque, and can work under various flexible, convenient and practical functional modules/modes such as zero rotating speed and braking torque.

The working mechanism is that the internal friction moment (the same applies below) is ignored, a planet gear carrier (101) is used as a power input end/shaft, a left half-shaft gear ring (102) is used as a power adjusting end, a right half-shaft sun gear (103) is used as a power output end/shaft, and according to the minimum energy consumption principle, the lever principle, the gear transmission principle and the energy conservation principle, four planet gears act simultaneously as four equal-arm levers and form a group of asymmetric planet gear transmission mechanisms with the left half-shaft gear and the right half-shaft gear. It is easy to see that the main power source rotates clockwise with constant rotation speed, the left half-shaft power input ends/shafts (139, 109) drive the planet gear carrier (101) to rotate clockwise, the planet gear carrier (101) drives the four planet gears (107 and 116) to revolve around the sun gear (103) clockwise on one hand and rotate anticlockwise on the other hand, and simultaneously drive the left half-shaft gear/cylindrical internal tooth gear ring (102) and the right half-shaft post gear/cylindrical external tooth sun gear (103) to rotate clockwise respectively;

If the power adjusting/speed regulating motor is operated at this time, the hollow rotor (130) applies forward torque to the left half-shaft gear ring (102), the torque accelerates the anticlockwise rotation speed of the four planetary gears, and simultaneously drives the right half-shaft sun gear (103) to increase clockwise torque, so that the clockwise rotation speed of the right half-shaft sun gear (103) is accelerated, and the power of the planetary gear carrier (101) and the power of the left half-shaft gear ring (102) are converged, so that the aim of accelerating the power output end/shaft (129) of the right half-shaft sun gear (103) is achieved, which is equivalent to working in an acceleration adjusting operation mode;

if the power adjusting/speed regulating motor is operated at this time, the hollow rotor (130) applies reverse torque to the left half-shaft gear ring (102), or the left half-shaft gear ring (102) rotates reversely, the reverse torque can enable the four planetary gears (107, 116) to reduce the anticlockwise rotation speed or the impact rotation torque, and further enable the right half-shaft sun gear (103) to brake or reduce the clockwise rotation torque, namely form braking torque, so that the purpose of stepless speed reduction of the power output end/shaft (129) of the right half-shaft sun gear (103) is achieved, which is equivalent to working in a speed reduction/emergency adjusting operation mode.

The embodiment is a device for combining the power addition/subtraction of the power adjusting end/shaft and the power input end/shaft into a power output end/shaft, so that the total power output by the main power source and the power adjusting/speed regulating motor is combined to the output end/shaft of the speed regulator, thereby achieving the purpose of real-time stepless speed regulation of the load. The power regulation/speed regulation motor control driver/vector control type frequency converter has five working modules/modes for calling, namely a ① soft start mode ② heat engine/light load mode ③ basic operation mode ④ stepless speed increasing operation mode ⑤ speed reducing/emergency regulation operation mode.

It is easy to see that the power input end/shaft, the power adjusting end/shaft and the power output end/shaft can be regarded as a causal adjustment relationship, namely, one or/and two factor variables are adjusted, even the third factor variable can be changed along with the causal adjustment relationship, for example, for a centrifugal load system, when the rotating speed is changed, the load power is changed in a 3-power index, the power is obviously reduced, the main mechanism of industrial energy conservation and emission reduction is realized, the working rotating speed, torque or/and shaft power of the power input end/shaft which are wanted and adapted can be obtained after the balance of the three energy transfer relationships is achieved, the system can respond in real time under different modes and achieve the most energy-saving working state, so as to meet different working condition process designs, working module/mode control flows and actual emergency requirements, and achieve the optimal practical effect of the invention. The conclusion of this working mechanism also applies to the following examples.

The differential transmission/power confluence mechanism assembly is integrally embedded in a hollow rotor of the power adjustment/speed regulation motor, and mainly consists of radial conical planetary gears (207 and 216), differential transmission/power confluence mechanism assemblies (201, 202, 203, 205, 206, 207 and 216), stators (220, 221, 222, 223, 224 and 233) and hollow rotors (230, 231, 232, 213 and 214) of the power adjustment/speed regulation motor, and other accessories (226, 210, 215, 225 and 238) of a stepless speed regulator based on the differential transmission/power confluence mechanism, Motor/generator duplex controllers and status sensors (not shown in the structural schematic of this embodiment). wherein, the radial conical planetary gear differential transmission/power converging mechanism component consists of an upper conical planetary gear (207) and a lower conical planetary gear (216), a straight-line type planetary gear shaft (205), a planetary gear carrier (201), left half shafts (209, 229) and conical gears (202, 203) which are identical in size and tooth number and are symmetrically arranged, a straight-line type/straight-pin type planetary gear shaft (205) is radially arranged on the planetary gear carrier (201), the central line of the straight-line type/straight-pin type planetary gear shaft (205) is perpendicular to the central lines of the left half shaft (209) and the right half shaft (229), and the upper conical planetary gear (207), 216 Is respectively and symmetrically connected with a left half shaft conical gear (202), 203 A right half shaft (229) is used as a power output end/shaft, the right half shaft (229) is arranged as a shafting right half rotor shaft (229) of a hollow rotor of a power adjusting/speed regulating motor through a right rotor end cover (214) and a stator end cover (224) which are matched on the right side, and extends out of the right rotor end cover (214) and the stator end cover (224) to form a shaft extension (249) of a power output shaft (229) of a stepless speed regulator based on a differential transmission/power converging mechanism, a left half shaft (209) is used as a power input end/shaft, and a left half shaft (209) is used as a power input end/shaft through a rotor end cover (213) and a stator end cover (233) which are matched on the left side, a separation/support bearing (210), 226 The left half rotor shaft (209) of the shafting of the hollow rotor of the power adjusting/speed regulating motor is arranged, and extends out of the left rotor end cover (213) and the stator end cover (233) to form the shaft extension (239) of the power input shaft (109) of the stepless speed regulator based on the differential transmission/power converging mechanism, the planet carrier (201) is used as a power adjusting end and is arranged into an integral structure or connected with the rotor core (231) of the hollow rotor body (230) of the power adjusting/speed regulating motor in a transmission way, and other accessories of the stepless speed regulator based on the differential transmission/power converging mechanism also comprise a stator shell/body (223), Stator core (221), stator field winding (222), rotor permanent magnet assembly (232), bolt fastener (238), and the like.

The mechanism is explained as follows, the planet carrier is used as the power adjusting end (omega _{Adjustment of 1}、M_{Adjustment of 1}、P_{Adjustment of 1}), the left half axle is used as the power input end/shaft (omega _{Into (I) 1}、M_{Into (I) 1}、P_{Into (I) 1}), the right half axle is used as the power output end/shaft (omega _{Out of 1}、M_{Out of 1}、P_{Out of 1}), the planet gear is equivalent to an equal arm lever according to the minimum energy consumption principle, the lever principle, the gear transmission principle and the energy conservation principle, because the left half axle gear and the right half axle gear are symmetrical and have equal radiuses, the planet gear is a differential device which can divide the torque or the power of the power adjusting end/shaft into two, and when the planet gear revolves and rotates, the differential device is similar to a differential in an automobile:

On the one hand, the angular velocity formula omega _{Into (I) 1}+ω_{Out of 1}＝2ω_{Adjustment of 1}, the torque distribution formula M _{Into (I) 1}＝M_{Out of 1}＝(1/2)*M_{Adjustment of 1} and the power formula P _{Out of 1}＝P_{Adjustment of 1}-P_{Into (I) 1} with conservation of energy, namely P _{Out of 1}＝P_{Adjustment of 1}-P_{Into (I) 1}, when the rotation speed of the power input end/shaft is constant, the power output end/shaft is allowed to obtain the desired torque, power or load rotation speed by adjusting the rotation direction and rotation speed of the power adjustment end/shaft (the formula allows the Xu Dongli adjustment/speed regulation motor or/and the main power source to reversely rotate or/and work with reverse torque, and correspondingly presents negative torque, negative angular speed or/and negative power, and is the same in the moment), on the other hand, the system allows real-time setting or by adjusting the positive torque, negative torque, power or/and rotation speed of the power adjustment end/shaft, and can instantly obtain stepless adjustable power, torque or/and load rotation speed, namely the reverse torque is allowed in the formula, and corresponds to the negative torque, on the other hand, the system also allows the power adjustment end/shaft to be set in a locking state (the power consumption of the power adjustment end/shaft is 0), namely _{Into (I) 1}+ω_{Out of 1}＝2ω_{Adjustment of 1}、ω_{Adjustment of 1} =0, and the rotation speed of the power adjustment end/shaft is equal to the rotation speed of the main power source, namely P=0, and the rotation speed of the main power source is equal to or less than the rotation speed of the load, and equal to the rotation speed of the main power source, and the load rotation speed is equal to or less in the moment when the rotation speed of the power input end is equal to the large.

It can be seen from the above that the power input end/shaft, the power adjustment end/shaft and the power output end/shaft are mutually adjustable variables, one or/and two of the variables are adjusted, even the third variable can be changed along with the adjusting variables (for example, for a centrifugal load system, when the rotating speed is changed, the load power is changed in a 3 rd power index way, etc.), and the working rotating speed, torque or/and shaft power of the power transmission end/shaft which is wanted and adapted can be obtained after the relational balance is achieved, so that the working mode and the control module are used for constructing, allocating or combining, and the system responds randomly and achieves an excellent working state, so as to meet different working condition designs, working mode control flows and practical application requirements.
