Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and cost is low, can, with the load variations power that automatically switches, change the double-power bidirectional automatic switching worm speed reducer of output speed.
Technical solution of the present utility model is:
A kind of double-power bidirectional automatic switching worm speed reducer, comprise driving clutch motor, free wheel device, output shaft, twice-enveloping worm gear pair and driving worm shaft motor, free wheel device is socketed on output shaft and with the output terminal of driving clutch motor and is connected, the worm screw of twice-enveloping worm gear pair is connected with driving worm shaft motor, the worm gear of twice-enveloping worm gear pair is connected with free wheel device, described free wheel device comprises pusher dog, star-wheel, outer ring, roller and spring, star-wheel coaxial package is in outer ring, the assembly of some groups of rollers and spring is evenly arranged at respectively in the circumferential wedge slot that star-wheel and outer ring form, pusher dog is inserted in wedge slot with roller and is and contacts or contact condition not, pusher dog is coaxially connected with the output shaft of driving clutch motor, star-wheel is coaxially connected with output shaft, outer ring is fixedly connected with the worm gear of twice-enveloping worm gear pair.
Further, between described pusher dog and driving clutch motor for flat key is connected.
Further, between described star-wheel and output shaft, be spline joint.
Further, between described outer ring and worm gear, be connected through threaded piece.
Again further, described worm gear is placed on output shaft by bearing.
Adopt after above technological scheme, the beneficial effect that the utility model reaches is:
(1) in the time that load changes, free wheel device automatic switchover input power; Use twice-enveloping reduction gearing mechanism, its bearing capacity is large, transmission efficiency is high, close structure, rationally, can be widely used in the gearing down in various gearings, and worm shaft can tow sides direction rotation, can realize two-way output.
(2) roller-type overrunning clutch with pusher dog, roller is not easy to wear, simple in structure, and cost is low.Input motor can automatically switch in the time that load is suddenlyd change.
Accompanying drawing explanation
Fig. 1 is the generalized section that the utility model is implemented
Fig. 2 is the sectional drawing of free wheel device
In Fig. 1: driving clutch motor 1, free wheel device 2, output shaft 3.
In Fig. 2: secondary gear envelope pair 4, drives worm shaft motor 5.
In Fig. 3: pusher dog 6, roller 7A, spring 7B, star-wheel 8, outer ring 9, wedge slot 10.
Embodiment
In Fig. 1,2,3, comprise driving clutch motor 1, free wheel device 2, output shaft 3, secondary gear envelope pair 4, drive worm shaft motor 5, pusher dog 6, roller 7A, spring 7B, star-wheel 8, outer ring 9 and wedge slot 10.Wherein free wheel device 2 comprises pusher dog 6, roller 7A, spring 7B, star-wheel 8, outer ring 9 and wedge slot 10, between star-wheel 8 and outer ring 9, form some wedge slots 10, in wedge slot 10, be provided with roller 7A and spring 7B, pusher dog 6 is connected with the output shaft of driving clutch motor 1 and is inserted in wedge slot 10, star-wheel 8 is connected with output shaft 3 keys, outer ring 9 is connected with the worm gear of secondary gear envelope pair 4, drives worm shaft motor 5 output shafts to be connected with the worm screw of secondary gear envelope pair 4.
Below in conjunction with accompanying drawing, the utility model and embodiment are described in further detail.
The utility model is operated in high speed light loading situation lower time, when driving clutch motor 1 drives pusher dog 6 clockwise high speed rotating, if outer ring is static, while rotating counterclockwise or clockwise rotate speed lower than pusher dog rotating speed, roller 7A is pushed to the large end of wedge slot 10 by pusher dog 6, between star-wheel 8 and outer ring 9 in separated state, pusher dog 6 promotes star-wheel 8 by roller 7A and rotates, and star-wheel 8 drives output shaft 3 to clockwise rotate, outputting power.When the load of bearing when output terminal increases suddenly, the rotating speed of output shaft 3, star-wheel 8, pusher dog reduces suddenly.Now drive worm shaft motor 5 to drive the worm screw of secondary gear envelope pair 4 to rotate, worm meshing worm drive, the outer ring 9 being fixedly connected with worm gear clockwise rotates.When the rotating speed of star-wheel 8 is down to when identical in outer ring 9, roller 7A is pushed to the small end of wedge slot 10 by spring 7B, wedging is between star-wheel 8 and outer ring 9, star-wheel 8 and outer ring 9 are combined as a whole, drive worm shaft motor 5 by worm screw, worm gear, outer ring 9, the inner ring of secondary gear envelope pair 4, power to be sent on output shaft 3 successively.Now driving clutch motor 1 drives the little end in contact of pusher dog pusher dog 6 at wedge slot 10, continues to follow rotation, drives worm shaft motor 5 to provide the output shaft 3 after load increases to export, and completes automatic switchover.
Otherwise, when driving clutch motor 1 drives pusher dog 6 counterclockwise high speed rotating, if outer ring is static, while clockwise rotating or clockwise rotate speed lower than pusher dog rotating speed, roller is positioned at the large end of wedge slot 10 all the time, between star-wheel 8 and outer ring 9 in separated state, pusher dog 6 directly promotes star-wheel 8 and rotates, and star-wheel 8 drives output shaft 3 to rotate counterclockwise, outputting power.When the load of bearing when output terminal increases suddenly, the rotating speed of output shaft 3, star-wheel 8, pusher dog reduces suddenly.Now drive worm shaft motor 5 to drive the worm screw of secondary gear envelope pair 4 to rotate, worm meshing worm drive, the outer ring 9 being fixedly connected with worm gear rotates counterclockwise.When the rotating speed of star-wheel 8 is down to when identical in outer ring 9, roller 7A is pushed to the small end of wedge slot 10 by spring 7B, wedging is between star-wheel 8 and outer ring 9, star-wheel 8 and outer ring 9 are combined as a whole, drive worm shaft motor 5 by worm screw, worm gear, outer ring 9, the inner ring of secondary gear envelope pair 4, power to be sent on output shaft 3 successively.Now driving clutch motor 1 drives pusher dog pusher dog 6 in the small end of wedge slot 10 and roller-contact, continues to follow rotation, drives worm shaft motor 5 to provide the output shaft 3 after load increases to export, and completes automatic switchover.
