Description
Technical field
The invention belongs to field of machining, and in particular to a kind of automatic anti-backlash worm wheel worm structure and its processing method with
The gap that disappears method.
Background technique
Worm Wheel System is a kind of common mechanically operated structure, and the helical teeth of worm screw is inserted into the helical teeth of worm gear, by
The rotation of worm screw drives worm gear rotation, due to having error in processing, also has abrasion in use process, thus worm and gear it
Between have gap certainly.Gap mainly has Changeable Lead worm screw between current elimination worm and gear, since Changeable Lead worm screw is processed
Difficulty is high, and the thickness for needing when assembling for the first time professional repeatedly to adjust worm screw gasket just can achieve the work of the gap that disappears
With it is also more next that the increasing precision in gap and gap can be generated again with the abrasion worm gear in use process and between worm screw
It is poorer, finally seriously affect the precision of workpieces processing.Therefore Changeable Lead worm screw is necessarily required to periodically be maintained by professional
The cooperation between its worm and wormwheel is adjusted, the efficiency of production is greatly reduced, also increases the cost used.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of automatic anti-backlash worm wheel worm structure and its processing sides
Method and the gap method that disappears.
In order to achieve the above object, the invention adopts the following technical scheme: a kind of automatic anti-backlash worm wheel worm structure, special
Sign is: including worm gear and worm screw, the worm gear and worm screw cooperate；The worm screw include worm shaft, worm set, spring,
Clamp nut and locking nut；The worm shaft is coupled with worm set by spline, and one end of the worm shaft and worm set is logical
It crosses the clamp nut and locking nut is fixed；The output end of the worm shaft is connect with servo motor, and the other end is known as adjusting
End is equipped with shoulder close to the adjustable side, and the thin shaft end of the shoulder two sides is known as worm shaft taper end, thick shaft end is known as worm shaft
Butt end, the worm set are covered in the outer surface of the shoulder；The clamp nut is mounted in the worm shaft taper end and compresses
One end of the worm set；One end of the spring is fixedly connected with the shoulder, the other end and the fixed company of the clamp nut
It connects；The locking nut is mounted in the worm shaft taper end and adjacent with the clamp nut.
