Abstract

The invention relates to a double power bi-direction auto switching worm reducer that includes motor, worm, worm wheel, output shaft, and bi-direction exceeding clutch. The inner star wheel is connected to the output shaft of exceeding clutch. And the outer shell is covered on the outer surface of inner star wheel. Several groups of rolling column and spring components are set in the round cuniform slot set on the inner star wheels. The invention could automatically switch to two working states of the high speed and low speed following the loader's change at the forward direction rotating or reverse direction rotating to form two different output speed and output torque to realize four output state.

Description

Double-power bidirectional automatic switching worm reducer
1, technical field:
The present invention is a kind of double-power bidirectional 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 component 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 control motor driving 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 has the service behaviour of required precision 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 bidirectional automatic switching worm 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 is band pusher dog double rolling key clutch, it includes pusher dog (2), star-wheel (3), outer shroud (4), roller (5A), roller (5B), spring (10A), spring (10B), 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 (5A) and spring (10A) is contained in respectively in the set circumferential wedge slot A of star-wheel (3), the assembly of some groups of rollers (5B) and spring (10B) be contained in respectively star-wheel (3) set with the symmetrical circumferential wedge slot B of wedge slot A in, pusher dog (2) connects with the output shaft of motor (1), and pusher dog (2) is inserted between roller (5A) and the roller (5B), 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 structure of roller 5B and roller 5A, spring 10A and spring 10B is identical.
The present invention is owing to adopt the structure of introducing the double rolling key clutch of a band pusher dog in worm reducer, coordinate the power of two motor inputs by clutch, turn to and to automatically switch at a high speed and two kinds of operating modes of low speed with the variation of outer load at positive and negative two, form two kinds of different output speeds and output torque, realize four kinds of output states altogether.The present invention 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, is a kind of deft design, function admirable, convenient and practical double-power bidirectional automatic switching worm reducer.

5, embodiment:
Embodiment:
Structural representation of the present invention as depicted in figs. 1 and 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 is band pusher dog double rolling key clutch, it includes pusher dog 2, star-wheel 3, outer shroud 4, roller 5A, roller 5B, spring 10A, spring 10B, 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 roller 5A and spring 10A is contained in respectively in the set circumferential wedge slot A of star-wheel 3, the assembly of some groups of roller 5B and spring 10B be contained in respectively star-wheel 3 set with the symmetrical circumferential wedge slot B of wedge slot A in, pusher dog 2 connects with the output shaft of motor 1, and pusher dog 2 is inserted between roller 5A and the roller 5B, 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 the rotation of outer shroud 4 clockwise directions, roller 5A is pushed to the big end of wedge slot A by outer shroud, and roller 5B is pushed to the big end of wedge slot B by pusher dog, make outer shroud 4 and star-wheel 3 be in the state of freeing, the two motion is independent of each other.Pusher dog 2 promotes star-wheel 3 by roller 5B and rotates, and star-wheel 3 drives output shaft 9 and counterclockwise rotates outputting power.
The present invention in the course of the work, when low speed heavy burden operating mode, when motor 1 drives pusher dog 2, pusher dog 2 by roller 5B promotion star-wheel 3, 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 5A drives the small end that enters wedge slot A by the thrust of spring 10A and by outer shroud 4, wedging star-wheel 3 makes outer shroud 4 and star-wheel 3 join together by roller 5A, and motor 6 participates in power output by worm screw 7, worm gear 8, outer shroud 4, roller 5A, star-wheel 3, output shaft 9 successively.At this moment, motor 1 drives pusher dog 2 roller 5B is remained on the big end of wedge slot B, and the high pulling torque of motor 6 behind the worm and worm gear deceleration force amplifier be by output shaft 9 output counterclockwise, thereby realizes the automatic switchover of power.
Otherwise when rotating as if pusher dog 2 clockwise directions, its working principle is same as described above, and just roller 5A is just opposite with roller 5B role.
