Power is converted from energy. When power does work, there are differences in energy conversion, size, and speed through fluid machinery. The common power transmission is to transmit power to specific mechanism components or machines through the transmission shaft. Therefore, the amount of work done by the transmission shaft will directly affect the work that the specific mechanism component or machine tool intends to provide. Common propulsion systems for power formation include: engines, vacuum pumps, internal combustion engines, compressors and other tools, through which the working fluid is used to generate power during the transmission process, and then the energy is transferred to specific mechanism components or tools through the transmission shaft (such as: fan , gear set), that is, to use the transmission shaft to work to provide the power source required by the specific mechanism component to perform preset operations, such as: driving the fan to provide air supply, driving the gear set to transmit driving force, driving tires to provide vehicle travel, etc.

The process of transmission of energy to specific mechanism components or implements by the transmission shaft is often due to defects in the driving operation process of the specific mechanism components or implements, so that the efficiency of the transmitted power cannot be improved. For example: the existing The exhaust gas produced by the equipment during the cycle movement is not completely exhausted due to insufficient exhaust. Even if it has been operated with supercharging, the exhaust gas still remains, causing the power transmission efficiency of each equipment after compression to be lower than expected, indirectly causing Reduced service life. Furthermore, some machines (such as: centrifugal pumps) are limited by the head in use due to the insufficient performance of the transmitted power, which leads to the problem of net positive suction head (Net Positive Suction Head; NPSH) must be considered during installation. That is, the suction port of the tool must be lower than a certain depth of the liquid surface, otherwise, liquid cavitation will occur, which will affect or invalidate the water absorption and delivery function, and cause inconvenience in actual installation.

detailed description

In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

Please refer to Fig. 1 and Fig. 2, the three-dimensional exploded view and combined view of the first embodiment of the power transmission system of the present invention, as shown in the figure, the power transmission system 1 of the present invention includes: a transmission device 2 and a power supply for the power transmission device 2 The source device 3, wherein the transmission device 2 includes: a cavity 20, a pair of rotors 21, a gear set 22, and a transmission shaft 23, the cavity 20 has a body 201, covers 202, 203 and are arranged on the body 201 The input port 204 and the output port 205 on the top, the input port 204 provides the inlet for the working fluid to enter the cavity 20 , and the output port 205 provides the outlet for the working fluid to flow out of the cavity 20 . The pair of rotors 21 includes a defined rotor 211 and a conjugated rotor 212 meshing with each other. Both are claw rotors with the same configuration and the same number of claws. The present embodiment adopts 4 identical claws. The defined rotor 211 of the present invention The mutual conjugate motion with the conjugate rotor 212 is achieved by the working fluid being delivered from the power source device 3 to the input port 204 of the cavity 20 , providing the radial motion that defines the positive force of the rotor 211 and the conjugate rotor 212 to rotate relative to each other. The gear set 22 includes a first gear 221 and a second gear 222 that mesh with each other. Spur gears (helical gears can also be used) are used, and the number of teeth of the first gear 221 and the second gear 222 are the same.

The power source device 3 (please refer to FIG. 3 ) includes: a power tool 30 for conveying working fluid and a shaft joint 31 assembled on the input port 204 and the output port 205 of the cavity 20, and a shaft joint 31 assembled on the power tool 30 The connecting pipe 32 between the shaft joint 31, wherein the power tool 30 can adopt hydraulic power or pneumatic power, includes a motor and a pump or a motor, a fluid storage tank and a fluid compressor. Once the working fluid enters through the set of connecting pipes 32, the working fluid enters the input port 204 through the shaft joint 31. At this time, the stationary rotor pair 21 will be pushed along with the pressure of the working fluid gradually increasing, and the working fluid will After the generated power is transmitted as effective energy, the working fluid flows to the output port 205 along the direction of rotation of the first gear 221 and the second gear 222 .

Please refer to FIG. 3 , a schematic diagram of the application of the first embodiment of the present invention to vehicle power transmission, and refer to FIG. 1 and FIG. The fluid compressor 302 is used to transmit the working fluid 303 (liquid or gas) stored in the fluid storage tank 301 to the transmission device 2 respectively through the fluid compressor or pump 302. Furthermore, when the automobile is in contact with the stationary tire 40 The frictional force is maximum when the ground is on the ground, and the fluid compressor 302 starts to transport the working fluid 303 into the rotor pair 21. However, because the automobile is stationary, the volume of the chamber 201 in the rotor pair 21 is fixed (because the rotor pair 21 has not yet rotated), but At this time, the working fluid 303 is continuously input, and the working fluid 303 provides the positive force of the rotor pair 21 (defining the rotor 211 and the conjugate rotor 212) to move relative to the radial direction. Once the pressure in the cavity 20 rises, The power acting on the surface of the rotor pair 21 will increase, and the positive force that impels the rotor pair 21 to move radially will also increase. When this positive force is greater than the maximum static friction force of the tire 40 relative to the ground, the wheel shaft 40 starts to rotate (that is, The power transmission shaft 23 starts to do work), at this moment, the volume of the chamber 201 of the rotor pair 21 begins to increase slowly, and the pressure gradually decreases. In terms of energy, the previously accumulated energy (high pressure) is output to the tire 40 to perform work Therefore, when the working fluid 303 passes through the input port 204 of the rotor pair 21 to the output port 205, that is, the pressure is reduced to about 1 atmosphere, which means that the energy is completely output to the wheel shaft 40, so the rotor pair 21 of the present invention is not expected to be used for energy transmission. The output port 205 of the rotor pair 21 maintains pressure so that the energy can be completely output to achieve the effect of effectively transferring the power generated by the working fluid 303 . Similarly, please refer to FIG. 4 , the working fluid 303 passes through the input port 204 of the rotor pair 21 to the output port 205 , and completely outputs energy through the transmission shaft 23 to make the fan 41 rotate.

Please refer to FIG. 5 and FIG. 6, the three-dimensional exploded view and assembled view of the second embodiment of the power transmission system 1' of the present invention, as shown in the figure, the difference between this embodiment and the first embodiment mainly lies in the transmission device 2 The pair of rotors includes a first-stage rotor pair 21 and a second-stage rotor pair 21', which are pivoted together in an axial series manner, and the input ports 204, 204' and output ports 205, 205 of the cavity 20, 20' 'corresponds to two sets, and the set of connecting pipes 31 can be assembled in series or in parallel with the input port 204, 204' and output port 205, 205' as the assembly reference (to be described later), and other components are all connected with The first embodiment is the same, in this way, the power tool 30 of the power source device 3, the first-stage rotor pair 21, the second-stage rotor pair 21' and the gear set 22 of the transmission device 2 can also be used as auxiliary power. Transmission, the power is continuously and stably transmitted and has the effect of high lift. Please refer to FIGS. 7A and 7B, the schematic diagrams of the third embodiment of the present invention applied to vehicle power transmission and water pumping in buildings, as shown in FIG. parallel assembly), when the power tool 30 transmits the working fluid 303 into the first-stage rotor pair 21 through the input port 204, the entering working fluid 303 will determine the pressure of the first-stage rotor pair 21 according to the load. In other words, when the car is stationary, the frictional force of the tires contacting the ground is the largest. At this time, the working fluid 303 enters the first-stage rotor pair 21. However, because the car is stationary, the volume of the chamber 201 of the first-stage rotor pair 21 is constant. (Because the first-stage rotor pair 21 has not yet rotated), but at this time, the continuous input of the working fluid 303 will cause the pressure in the chamber 201 of the first-stage rotor pair 21 to rise. Once the pressure rises, it will act on the first stage. The power of the first-stage rotor to the surface of 21 will increase, and the positive force of the radial movement of the first-stage rotor to 21 will also increase. When this positive force is greater than the maximum static friction force of the tire 40 relative to the ground, the wheel shaft 23 starts to rotate. The volume of the chamber 201 of the first-stage rotor pair 21 begins to increase slowly, and the pressure gradually decreases. In terms of energy, the previously accumulated energy (high pressure) has been output to the tire 40 to perform work. Therefore, when the working fluid 303 passes through the input port 204 of the first-stage rotor pair 21 to the output port 205, that is, the pressure is reduced to 1 atmosphere, indicating that the energy has been completely output to the tire 40, so the first-stage rotor pair 21 of the present invention is not suitable for energy transmission. It is hoped that the output port 205 of the first-stage rotor pair 21 maintains pressure so that the energy can be completely output. That is to say, a part of the energy still exists in the fluid at the output port 205 of the first-stage rotor pair 21 , which is not completely used by the tire 40 . When the power tool 30 transmits the working fluid 303 into the second-stage rotor pair 21' through the input port 204, the entering working fluid 303 can be used according to the object of the second-stage rotor pair 21' (for example: the radiator fan in the vehicle), Cooperating with the first-stage rotor pair 21, the working fluid 303 is passed through the input port 204' and the output port 205' to effectively transmit power.

Please refer to FIG. 7B again, which is a schematic diagram of the application of the present invention to building water pumping, that is, the second-stage rotor pair 21' acts as a pump. When the power tool 30 transmits the working fluid 303 into the first-stage rotor pair 21 through the input port 204, the entering The working fluid 303 will determine the pressure of the first-stage rotor pair 21 according to the head of the second-stage rotor pair 21 ′. In other words, the output port 205 of the first-stage rotor pair 21 is connected to the atmosphere (that is, the power tool 30 ). The input port 204 ′ of the secondary rotor pair 21 ′ is connected to the water pipe (water tank) on the first floor, and the output port 205 ′ of the second stage rotor pair 21 ′ is connected with the water pipe 80 of the water tank (water tower) on the top floor. When the input port 204 of the first-stage rotor pair 21 receives the working fluid 303, the first-stage rotor pair 21 can rotate easily (because the lift is low and the load is small), and when the first-stage rotor pair 21 starts to rotate, the first-stage rotor pair 21 Coaxially drives the gear set 22 (the gear set is only used for energy transmission and the rotor pair maintains conjugate relative radial motion) and the second-stage rotor pair 21'. When the second-stage rotor pair 21' starts to rotate, the The tap water can be transported. As the floor increases, that is, the head (the load of the second-stage rotor pair 21') increases, and the second-stage rotor pair 21' is compressed by conjugate rotation (the purpose is to cope with the required building height). When When the load is getting bigger and bigger (the height of the building is getting higher and higher), if you want to maintain its speed, you need to increase the torque, that is, increase the positive direction of the input port 204 of the first-stage rotor pair 21 acting on the surface of the first-stage rotor pair 21. That is to say, the pressure of the input port 204 of the first-stage rotor pair 21 needs to be increased in order to maintain the pressure of the output port 205 of the first-stage rotor pair 21 at 1 atmosphere, which means that the energy of the input port 204 of the first-stage rotor pair 21 is completely It is converted into shaft work so as to provide the second-stage rotor pair 21' for water delivery to high-rise buildings.

7A and 7B, the set of connecting pipes 31 of the present invention is assembled in parallel with the input port 204, 204' and output port 205, 205' as the assembly reference, and the power is transmitted to the wheels and the application of pumping water respectively. In other words, the power of the present invention is coaxially transmitted from the power tool 30 of the power source device 3 to the working fluid 303, and then transmitted to the power transmission system 1 through two sets of input ports 204, 204' and output ports 205, 205' respectively. ', and through the first-stage rotor pair 21 and the second-stage rotor pair 21' and the gear set 22 of the transmission device 2 for auxiliary power transmission, respectively provide the power of the wheels 40 and other equipment (pumps) that require power, In this way, power can also be continuously, effectively and stably transmitted respectively.

As shown in Figures 8A and 8B, the fourth embodiment of the power transmission system 1' of the present invention is connected in series to apply to vehicle power transmission and fan transmission. This embodiment also includes two sets of rotor pairs of the transmission device 2. 21, 21' and gear set 22, the working fluid 303 is used as auxiliary power transmission, and the two groups of rotor pairs 21 and 21' take the input ports 204, 204' and output ports 205, 205' as Assembling standards are articulated together in series, so that power can also be provided for continuous, effective and stable transmission.

In summary, the power transmission system provided by the present invention can transmit the power generated by the working fluid as effective energy, that is, completely output the energy formed by the working fluid during the transmission process to the drive shaft, so that the drive shaft Work is the complete transfer of energy to a specific mechanism component or machine. In addition, the power transmission system can maintain the transmitted power at atmospheric pressure, so as to provide a high-lift transmission effect, which is beneficial to the actual installation work.

As mentioned above, for those of ordinary skill in the art, various other corresponding changes and deformations can be made according to the technical scheme and technical concept of the present invention, and all these changes and deformations should belong to the protection scope of the claims of the present invention .
