Abstract
The utility model discloses a kind of adjustable worm structure, wherein, including: a worm gear is rotating to be fixed on a base, and described base is further fixed on two worm screw fixed structures, one worm screw is rotatably fixed on described in two between worm screw fixed structure, engages with described worm gear in the middle part of described worm screw；Described worm screw fixed structure includes: a worm screw is fixed seat and is fixed on a regulation support, described regulation support is fixed on described base by multiple adjusting nuts, described worm screw is fixed seat and has a bearing, and the end of described worm screw is fixed on described worm screw fixes in seat by described bearing is rotating.This utility model solves worm gear and worm screw excesssive gap in prior art, and the problem affecting using effect, by arranging regulation support, it is achieved worm gear and the adjustment of worm screw fit clearance.
Description
Technical field
This utility model relates to a kind of worm structure, particularly relates to a kind of adjustable worm structure.
Background technology
Worm-and-wheel gear is commonly used to transmit the motion between two alternating axis and power.Being equivalent to wheel and rack in worm gear and worm screw plane therebetween, worm screw is similar to screw configuration again.
Worm and gear reducing gear case on market, universal worm gear coordinates with worm screw and there is certain interval, and due to cantilever beam structure problem, original interstice is amplified to cantilever beam end, and gap reaction is excessive, affects using effect.
Utility model content
The utility model discloses a kind of adjustable worm structure, in order to solve worm gear and worm screw excesssive gap, the problem affecting using effect in prior art.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions:
A kind of adjustable worm structure, wherein, including: a worm gear is rotating to be fixed on a base, and described base is further fixed on two worm screw fixed structures, and a worm screw is rotatably fixed on described in two between worm screw fixed structure, engages with described worm gear in the middle part of described worm screw；Described worm screw fixed structure includes: a worm screw is fixed seat and is fixed on a regulation support, described regulation support is fixed on described base by multiple adjusting nuts, described worm screw is fixed seat and has a bearing, and the end of described worm screw is fixed on described worm screw fixes in seat by described bearing is rotating.
Adjustable worm structure as above, wherein, the one end of described worm screw stretches out worm screw described in and fixes seat, and described base is also equipped with a drive mechanism, and described drive mechanism is to the one end transmission of described worm screw.
Adjustable worm structure as above, wherein, is also included that an anti-return nut, the other end of described worm screw stretch out another described worm screw and fix seat, is fixed in described bearing by described anti-return nut.
Adjustable worm structure as above, wherein, described adjusting nut has the three: first adjusting nut, the second adjusting nut, the 3rd adjusting nut.
Adjustable worm structure as above, wherein, described first adjusting nut, described second adjusting nut, described 3rd adjusting nut fix the distance of seat the most from the close-by examples to those far off apart from described worm screw.
In sum, owing to have employed technique scheme, this utility model solves worm gear and worm screw excesssive gap in prior art, and the problem affecting using effect, by arranging regulation support, it is achieved worm gear and the adjustment of worm screw fit clearance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the adjustable worm structure of this utility model.
Detailed description of the invention
With embodiment, this utility model is described further below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of the adjustable worm structure of this utility model, refer to Fig. 1, a kind of adjustable worm structure, wherein, including: a worm gear 2 is rotating to be fixed on a base 1, being further fixed on two worm screw fixed structures 4 on base 1, a worm screw 3 is rotatably fixed between two worm screw fixed structures 4, engages with worm gear 2 in the middle part of worm screw 3；Worm screw fixed structure 4 includes: a worm screw is fixed seat 41 and is fixed on a regulation support 42, regulation support 42 is fixed on base 1 by multiple adjusting nuts 43, worm screw is fixed seat 41 and has a bearing, and the end of worm screw 3 is fixed on worm screw fixes in seat 41 by bearing is rotating.
The one end of worm screw 3 of the present utility model stretches out a worm screw and fixes seat 41, and base 1 is also equipped with a drive mechanism 6, and drive mechanism 6 is to the one end transmission of worm screw 3.
This utility model also includes an anti-return nut 5, and the other end of worm screw 3 is stretched out another worm screw and fixed seat 41, is fixed in bearing by anti-return nut 5.
Adjusting nut 43 of the present utility model has the three: first adjusting nut, the second adjusting nut, the 3rd adjusting nut.
First adjusting nut of the present utility model, the second adjusting nut, the 3rd adjusting nut distance worm screw fix the distance of seat the most from the close-by examples to those far off.
In an embodiment of the present utility model, this utility model worm screw 3 with the gap adjustment of worm gear 2 can be: loosens the second adjusting nut, tightens up the 3rd adjusting nut and is furthered by worm screw 3 worm gear 2；Loosen the 3rd adjusting nut, tighten up the second adjusting nut, by worm screw 3 away from worm gear 2.
