Abstract
A kind of gap eliminator for worm and wormwheel, comprising: shell, worm gear, eccentric bushing, worm screw and eccentric bushing lockable mechanism.Worm screw is that eccentric rotary is mounted in eccentric bushing, therefore when rotating eccentric sleeve, eccentric bushing drives worm screw to generate eccentric rotary, to change the center of worm and wheel away from, to realize the gap gradually eliminated between worm gear and worm screw, structure is simple, easily operated, it is that can reach the effect for eliminating gap that part, which need not be dismantled, with being worn when worm gear is with worm screw use, it can adjust at any time, improve the transmission accuracy of worm gear and worm screw.
Description
Technical field
The utility model relates to technical field of mechanical transmission, and in particular to a kind of gap eliminator for worm and wormwheel.
Background technique
For worm and gear component, existing gap is eliminated between worm gear and worm screw, otherwise will shadow
Ring the precision of Worm Wheel System.But in worm and gear runing condensation procedure, worm gear, which generates abrasion, leads to the gap of worm and gear
Can become larger, existing worm and gear anti-backlash mechanism cannot well with worm and gear wear carry out suitability the gap that disappears,
To influence the transmission accuracy of Worm and worm-wheel gearing.
Summary of the invention
The utility model in order to overcome the shortcomings of the above technology, provide a kind of clearance cross change worm gear and worm screw center away from
Realize the device for eliminating gap between worm and gear.
The utility model overcomes the technical solution used by its technical problem to be:
A kind of gap eliminator for worm and wormwheel, comprising:
Shell, it is internal that worm gear is rotatably equipped with by bearing I；
Eccentric bushing is rotatablely installed in shell, the axis of eccentric bushing and the axis perpendicular of worm gear, is arranged on eccentric bushing
There is fluting；
Worm screw, by the rotational installation of bearing II in eccentric bushing, the axis of worm screw and the eccentric axis of eccentric bushing are arranged,
Worm screw is meshed in fluting in worm gear；And
Eccentric bushing lockable mechanism, for fixing the eccentric bushing rotateing in place with respect to shell locking.
Further, above-mentioned eccentric bushing lockable mechanism includes the screw hole being set on shell and is set to eccentric bushing front end
The long hole being arc-shaped, bolt pass through long hole back spin together in screw hole.
The beneficial effects of the utility model are: worm screw is that eccentric rotary is mounted in eccentric bushing, therefore works as rotating eccentric sleeve
When eccentric bushing drive worm screw to generate eccentric rotary, to change the center of worm and wheel away from gradually eliminating worm gear to realize
Gap between worm screw, structure is simple, easily operated, is that can reach the effect for eliminating gap without disassembly part, with snail
It is worn when wheel is with worm screw use, can adjust at any time, improve the transmission accuracy of worm gear and worm screw.
Detailed description of the invention

Specific embodiment
With reference to the accompanying drawing 1, attached drawing 2 is described further the utility model.
A kind of gap eliminator for worm and wormwheel, comprising: shell 1, it is internal that worm gear 3 is rotatably equipped with by bearing I 2；It is eccentric
Set 5 is rotatablely installed in shell 1, the axis of eccentric bushing 5 and the axis perpendicular of worm gear 3, is provided with fluting on eccentric bushing 5
8；Worm screw 4, by the rotational installation of bearing II 7 in eccentric bushing 5, the axis of worm screw 4 and the eccentric axis of eccentric bushing 5 are arranged,
Worm screw 4 is in worm gear 3 in fluting 8 and is meshed；And eccentric bushing lockable mechanism, the eccentric bushing 5 for will rotate in place is with respect to shell
1 locking of body is fixed.Since worm screw 4 is that eccentric rotary is mounted in eccentric bushing 5, when rotating eccentric sleeve 5, eccentric bushing 5 is driven
Worm screw 2 generates eccentric rotary, thus change the center of worm screw 4 and worm gear 3 away from, thus realize gradually eliminate worm gear 3 and worm screw 4 it
Between gap, structure is simple, easily operated, is that can reach the effect for eliminating gap without disassembly part, with worm gear 3 and worm screw
4 wear when using, and can adjust at any time, improve the transmission accuracy of worm gear 3 Yu worm screw 4.
Eccentric bushing lockable mechanism can be following structure comprising the screw hole 6 that is set on shell 1 and be set to bias
The long hole 9 of 5 front ends being arc-shaped is covered, bolt passes through 9 back spin of long hole together in screw hole 6.When needing rotating eccentricity to cover 5, pine
Open bolt, eccentric bushing 5 can be rotated, and bolt rotates in long hole, and screwing bolts can will be eccentric after eccentric bushing 5 rotate in place
It covers opposite 1 locking of shell to fix, operation is simple and reliable.
