Abstract
The utility model relates to a worm-gear-worm driving device which belongs to the mechanical driving class. The utility model comprises a base, a worm gear and a worm, wherein the worm gear is fixed to a shaft and is arranged on the base; a worm seat is arranged outside the worm; a bearing is arranged between the worm and the worm seat. The utility model is characterized in that the base is provided with a guide rail composed of a fixed block and a slide block; the slide block is fastened with the bottom of the worm seat into a whole; the fixed block is fixed to the base; the outer side of the worm seat is connected with the base by a spring. The utility model makes the worm seat slide in the guide rail through the elastic force of the spring, and thus, 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: a guide rail is arranged on the pedestal, guide rail is made of fixed block and slide block, slide block and worm screw seat bottom fasten as one, and fixed block is fixed on the pedestal, and the worm screw seat outside is connected on the pedestal by spring.
Worm screw seat of the present utility model is owing to the slide block of bottom and guide rail is fixed as one, the outside is connected on the pedestal by spring, the elastic force of spring can be pushed the worm screw seat to worm gear, the worm screw seat is slided in guide rail, 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.
Fig. 2 is the utility model A-A sectional drawing (amplification).
Embodiment
As shown in Figure 1, 2, 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, and worm screw seat 5 is arranged outside the worm screw 4, between worm screw 4 and the worm screw seat 5 bearing 6 is arranged, it is characterized in that: a guide rail is arranged on the pedestal 1, and guide rail is made of fixed block 9 and slide block 8, and slide block 8 fastens as one with worm screw seat 5 bottoms, fixed block 9 is fixed on the pedestal 1, and worm screw seat 5 outsides are connected on the pedestal 1 by spring 7.
The utility model slides worm screw seat 5 by the elastic force of spring 7 in guide rail, eliminate the gap of 4 of worm gear 2 and worm screws, thereby eliminates the reversing drive error of worm gear, worm screw.
