Abstract
The double power input automatically switching reducer includes two motors, worm, worm gear, output shaft, casing and overrunning clutch comprising pusher dog, inner spider, outer ring, roller and spring. It has inner spider connected to the output shaft, outer ring around the inner spider, roller and spring assembly inside the wedged slot of the inner spider, pusher dog connected to the output shaft of one motor and inserted between the roller and the inner spider, worm connected to the output shaft of the other motor, worm gear and worm constituting one spiral transmission pair, worm gear around the output shaft, and outer ring connected to the worm gear. The present invention has simple structure, and can switch power and alter the output speed automatically with the changed load.
Description
1, technical field:
The present invention is a kind of double-power inputting automatic shifting speed reducer, and particularly a kind of double dynamical input automatic switching worm reducer belongs to the innovative technology of double dynamical input retarder.
2, background technique:
For the bigger periodic job machinery of load variations, as forming machine, it requires actuator's speed low in a duty cycle during Workpiece shaping, and it is big to exert oneself, and then require actuator's speed height At All Other Times, but it is little to load.The speed of these two kinds of operating modes, load differ tens times to tens times, therefore, need with the different motoring of two performances to satisfy above-mentioned requirements.Traditional method is that this two motors is connected by steerable ordinary clutch (as friction clutch, jaw clutch etc.) or break, but the shortcoming that these methods exist is a complex structure, the cost height, and additional control is handled driving mechanism is easy to generate impact during sudden load change, so that influence the service behaviour of Work machine.
3, summary of the invention:
The objective of the invention is to consider the problems referred to above and provide a kind of not only simple in structure, cost is low, stable drive, and can be along with automatically switch power and change output speed of load variations, and need not to add in addition the double-power inputting automatic shifting speed reducer of control system.
Structural representation of the present invention as shown in Figure 1, include motor (1), motor (6), worm screw (7), worm gear (8), reducer output shaft (9), casing (11) and free wheel device, wherein free wheel device includes pusher dog (2), star-wheel (3), outer shroud (4), roller (5), spring (10), star-wheel (3) connects with reducer output shaft (9), outer shroud (4) is nested with the outside in star-wheel (3), the assembly of some groups of rollers (5) and spring (10) is contained in respectively in the set corresponding circumferential wedge slot (31) of star-wheel (3), pusher dog (2) connects with the output shaft of motor (1), and pusher dog (2) is inserted between roller (5) and the star-wheel (3), worm screw (7) connects with the output shaft of motor (6), worm gear (8) is formed the power screw pair with worm screw (7), and worm gear (8) sky is enclosed within on the reducer output shaft (9), and outer shroud (4) connects with worm gear (8) by link (12).
The present invention coordinates the power of two motor inputs by clutch, and can automatically switch at a high speed and two kinds of operating modes of low speed with the variation of outer load owing to adopt the structure of introducing the free wheel device of a band pusher dog in worm reducer.Therefore, it is not only simple in structure, and cost is low, and need not to add the automatic switchover that control gear can be realized power in addition, and transmission is more steady.The present invention is a kind of deft design, function admirable, convenient and practical double-power inputting automatic shifting speed reducer.

5, embodiment:
Embodiment:
Structural representation of the present invention such as Fig. 1, shown in 2, include motor 1, motor 6, worm screw 7, worm gear 8, reducer output shaft 9, casing 11 and free wheel device, wherein free wheel device includes pusher dog 2, star-wheel 3, outer shroud 4, roller 5, spring 10, star-wheel 3 connects with reducer output shaft 9, outer shroud 4 is nested with the outside at star-wheel 3, the assembly of some groups of rollers 5 and spring 10 is contained in respectively in the set corresponding circumferential wedge slot 31 of star-wheel 3, pusher dog 2 connects with the output shaft of motor 1, and pusher dog 2 is inserted between roller 5 and the star-wheel 3, worm screw 7 connects with the output shaft of motor 6, worm gear 8 is formed the power screw pair with worm screw 7, and worm gear 8 skies are enclosed within on the reducer output shaft 9, and outer shroud 4 connects with worm gear 8 by link 12.In the present embodiment, above-mentioned star-wheel 3 connects with reducer output shaft 9 by key 13, and pusher dog 2 connects with motor 1 by key 14, and worm screw 7 connects with motor 6 by key, worm gear 8 is enclosed within on the reducer output shaft 9 by rolling bearing 15 skies, and link 12 is a threaded connector.
The present invention in the course of the work, when light lotus operating mode at a high speed, when motor 1 drives pusher dog 2 counter clockwise direction high speed rotating, as shown in Figure 1, as long as outer shroud 4 counter clockwise direction rotational speeies are lower than pusher dog 2, or outer shroud 4 does not change, or outer shroud 4 clockwise directions rotation, roller 5 all is pushed to the big end of wedge slot 31, makes outer shroud 4 and star-wheel 3 be in the state of freeing, and the two motion is independent of each other.Pusher dog 2 directly promotes star-wheel 3 and rotates, and star-wheel 3 drives output shaft 9 and counterclockwise rotates outputting power.
When light lotus operating mode at a high speed, when motor 1 drove pusher dog 2 clockwise directions and rotates, pusher dog 2 was pushed roller 5 at the big end of wedge slot 31, last roller 5 compresses the another side of star-wheel 3, promote star-wheel 3 and rotate, star-wheel 3 drives output shaft 9 clockwise directions and rotates outputting power.At this moment, owing to the big end of roller 5 at wedge slot 31, outer shroud 4 is in the state of freeing with star-wheel 3, and the two motion is independent of each other.
The present invention in the course of the work, when low speed heavy burden operating mode, drive star-wheels 3 when motor 1 drives pusher dog 2, pusher dog 2, when output shaft 9 is made counterclockwise high speed rotating, if the outer load that output shaft 9 is subjected to increases suddenly suddenly, surpass the moment of torsion that motor 1 can be born, then the rotating speed of output shaft 9, star-wheel 3, pusher dog 2 falls suddenly.At this moment, motor 6 is also driving worm screw 7 rotations, worm screw 7 drives worm gears 8, outer shroud 4 and is rotated counterclockwise as low speed, in case the speed drop of output shaft 9, star-wheel 3 and pusher dog 2 is to fast together with outer shroud 4, then roller 5 drives the small end that enters wedge slot 31 by the thrust of spring 10 and by outer shroud 4, wedging star-wheel 3 makes outer shroud 4 and star-wheel 3 join together by roller 5, and motor 6 participates in power output by worm screw 7, worm gear 8, outer shroud 4, roller 5, star-wheel 3, output shaft 9 successively.At this moment, the high pulling torque of motor 6 behind the worm and worm gear deceleration force amplifier is by output shaft 9 output counterclockwise, thus the automatic switchover of realization power.
