Abstract
The utility model discloses a stepless speed regulation differential mechanism, which comprises a casing with inner teeth, wherein, one end of the casing is fixed with the stator of an auxiliary motor; a gear on the rotor of the auxiliary motor is engaged with a first planetary mechanism; the extension end of the first planetary mechanism is engaged with a second planetary mechanism; the first planetary mechanism and the second planetary mechanism are engaged with the inner teeth arranged on the casing. A large portion of the work load of the whole machine of the utility model is borne by a main motor. So the auxiliary motor can obtain smaller power. Thereby, the work efficiency of the whole machine is improved. Meanwhile, the utility model has the advantages of small size, light weight, high efficiency, reliability, high durability, large bearing capability, stepless regulation of rotary speed difference, etc. Besides, the utility model can not be changed with the variation of the operating condition of the main motor.
Description
A kind of stepless speed regulation differential mechanism relates to specially the arrangement or the configuration of the transmission device that designs for centrifuge.
In the helical-conveyer centrifugal, a speed discrepancy should be arranged between rotary drum and the spiral.This speed discrepancy is to be realized by the transmission device that is installed between motor and the working machine.A kind of " the horizontal helico-centrifuger stepless speed regulation differential mechanism " main structure that discloses as No. the 91220130.4th, Chinese patent is by differential system, and differential transmission systems, speed governing deceleration system and automatic control and alarm system form.Differential system is made up of a planetary gear train, and differential transmission systems is made of six gears, and the speed governing deceleration system is made up of the level Four reduction gears mechanism.This differential mechanism has differential, stepless speed regulation, synchronous overload protection, the multiple function of automatic control alarm.
The purpose of this utility model provides a kind of stepless speed regulation differential mechanism, and its speed discrepancy is stepless adjustable, and does not change with main motor working conditions change.
For achieving the above object, this stepless speed regulation differential mechanism comprises the shell of being with internal tooth, and an end of described shell is fixed with the stator of auxiliary motor.The epitrochanterian gear of auxiliary motor is meshed with first planetary mechanism, and the first planetary mechanism extending end is meshed with second planetary mechanism.First planetary mechanism and second planetary mechanism all are meshed with the internal tooth on the shell.
The shell of band internal tooth is with the bowl Joint during use, and the extending end of second planetary mechanism is with the spiral Joint.The described shell of main driven by motor rotates, thereby shell, the auxiliary motor stator of bowl, band internal tooth are rotated synchronously.The auxiliary motor rotor then makes the relative rotary drum of spiral produce a speed discrepancy by first planetary mechanism and second planetary mechanism.Adjust the rotating speed of auxiliary motor and then can regulate this speed discrepancy easily.
The work loads major part of the utility model complete machine is born by main motor.The relative rotary drum of just spiral that auxiliary motor bore pushes that part of work loads that material produced.So the desirable less power of auxiliary motor, thereby also just improved the working efficiency of complete machine greatly.Simultaneously, the utility model have also that volume is little, in light weight, efficient is high, reliability and durability, bearing capacity is big, the stepless adjustable and advantages such as variation with main motor working conditions change not of speed discrepancy.
Below in conjunction with drawings and Examples the stepless speed regulation differential mechanism that foundation the utility model proposes is further described.
The stepless speed regulation differential mechanism schematic diagram that Fig. 1 the utility model proposes for foundation.
The stepless speed regulation differential design schematic representation that Fig. 2 the utility model proposes for foundation.
Fig. 3 is for adopting the horizontal helico-centrifuger structural representation according to the stepless speed regulation differential mechanism that the utility model proposes.
As shown in Figure 1, the stator (10) of the affixed auxiliary motor of an end of shell (1), and have internal tooth (6) on the shell.Gear (8) on the auxiliary motor rotor (9) is meshed with first planetary mechanism.First planetary mechanism is made up of first planetary pinion (7) and first planet carrier (5), and wherein the extending end of first planet carrier has gear (3), and the gear on this extending end is meshed with second planetary mechanism.Second planetary mechanism is made up of second planetary pinion (4) and second planet carrier (2), and the extending end of this planet carrier is an output terminal.
Referring to Fig. 2, the stator of auxiliary motor (10) is fixed in an end of shell (1) again, and the last end of its rotor (9) is fixed with gear (8), and the other end is equipped with slip ring (12).First planetary pinion (7) is contained on first planet carrier (5) by bearing, and this planetary pinion is meshed with internal tooth (6) and the epitrochanterian gear of auxiliary motor (8) on the shell simultaneously.First planet carrier and first planetary pinion are formed first planetary mechanism.Second planetary mechanism is made up of second planetary pinion (4) and second planet carrier (2).The extending end of first planet carrier is fixed with gear (3), also promptly is made of the extending end of first planet carrier minor axis (11), gear (3) is fixed on the minor axis again.This extending end is meshed with second planetary mechanism by gear fixed thereon.Specifically, just be meshed with second planetary pinion (4).Simultaneously, second planetary pinion also is meshed with the internal tooth on the shell.Second planetary pinion is contained on second planet carrier by bearing.
Between main motor and shell, preferably adopt belt transmission, also can adopt chain transmission, belt pulley or sprocket wheel can be installed for this reason on shell.
See Fig. 3 according in the stepless speed regulation differential mechanism using process that the utility model proposes with the annexation of centrifuge.The rotary drum of centrifuge (13) is with shell (1) Joint of described differential mechanism.And the same spiral of extending end (14) Joint of planet carrier in second planetary mechanism of described differential mechanism.On the described differential mechanism belt pulley is housed, and links to each other with main motor by belt (15).
