Abstract
The utility model relates to a worm-gear worm driving device which belongs to the mechanical driving class. The worm-gear worm driving device comprises a worm gear, a worm and a base, wherein the worm gear is fixed to a shaft and is arranged on the base. The utility model is characterized in that one end of a worm seat is connected with the base by a positioning pin; the worm seat can rotate at a certain angle around the positioning pin; the lateral surface on the other end of the worm seat is connected with a spring, and one end of the spring is fixed to the base. In the utility model, by the elastic force of the spring, the worm seat rotates around the positioning pin and gaps between the worm gear and the worm are eliminated. The utility model has the advantage of simple structure.
Description
Technical field
The utility model belongs to the mechanical transmission class, specifically is a kind of worm gearing.
Background technique
At present, in the device that adopts the worm and gear transmission, generally worm gear and axle are fixed and be contained on the pedestal, worm screw also is contained on the pedestal by bearing, bearing housing, the between centers invariant position of worm and wheel.But in worm gear and the actual manufacture process of worm screw, all have foozle inevitably, cause both in transmission process, to have drive gap inevitably, thereby cause worm gear and worm screw reversing drive error.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, provides a kind of simple and reasonable, thereby can effectively eliminate the worm gearing of drive gap elimination worm gear, worm screw reversing drive error between worm gear, worm screw.
The technical solution of the utility model is as follows:
A kind of worm gearing, comprise pedestal, worm gear, worm screw, worm gear is fixed and is contained on the pedestal with axle, worm screw has the worm screw seat outward, between worm screw and the worm screw seat bearing is arranged, of the present utility model being characterised in that: be connected by locating stud between worm screw seat one end and the pedestal, the worm screw seat can be around locating stud center rotating certain angle, the outer side surface of the other end of worm screw seat is connecting spring, and spring one end is fixed on the pedestal.
Worm screw seat of the present utility model is fixed on the pedestal by locating stud owing to an end, the other end can be pushed the worm screw seat to worm gear by the elastic force that is contained in the spring on the pedestal, thereby can eliminate the drive gap of worm gear, worm screw, and then eliminate reversing drive error between worm gear, worm screw, the utility model is simple and reasonable, and is satisfactory for result.
The drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a kind of worm gearing, comprise worm gear 2, worm screw 4, pedestal 1, worm gear 2 is fixed and is contained on the pedestal 1 with axle 3, outside the worm screw 4 worm screw seat 5 is arranged, and between worm screw 4 and the worm screw seat 5 bearing 6 is arranged, it is characterized in that: be connected by locating stud 8 between worm screw seat 5 one ends and the pedestal 1, worm screw seat 5 can be around locating stud 8 center rotating certain angle, and the outer side surface of the other end of worm screw seat 5 is connecting spring 7, and spring 7 one ends are fixed on the pedestal 1.
The utility model makes worm screw seat 5 rotate around locating stud 8 by the elastic force of spring 7, eliminates the gap of 4 of worm gear 2 and worm screws, thereby eliminates the reversing drive error of worm gear, worm screw.
