Abstract

The invention discloses a gear engagement gap eliminating device, and relates to the technical field of industrial automation. A large gear 1 is fixed at one end of a transmission shaft; the transmission shaft is connected with a box by a bearing; a small gear 1 is engaged with the large gear 1, and is also engaged with a large gear 2; the large gear 2 is mounted at the other end of the transmission shaft by a bush; the outer end surface of the large gear 2 is connected with a thrust bearing by springs; a screw penetrates through the thrust bearing; the springs are fixed on the large gear 2; the outer side of the thrust bearing is positioned by using a ring; the ring and the thrust bearing coat the transmission shaft in sequence; a small gear 2 is mounted opposite to the small gear 1, and is engaged with the large gear 1 and the large gear 2; the small gear 2 is connected with the box by a bearing and a bearing base; the small gear 1, the small gear 2, the large gear 1 and the large gear 2 are all bevel gears; the springs are three pressure springs; and the three springs are uniformly distributed along the end surface of the large gear 2. The gear engagement gap eliminating device eliminates gear gaps, can always keep traditional transmission precision, and is simple in structure, convenient and practical.

Description

A kind of elimination gear backlash device
Technical field
The present invention relates to technical field of automation in industry, specifically a kind of elimination gear backlash device.
Background technology
In existing industrial automation, major part gear drive is all connected transmission by structural member, and two meshing gears keep fixed position relative constant.Traditional gear transmission structure there will be the phenomenon of gear wear in long-term motion process, makes the outfan of drive mechanism cannot keep original precision, and gear drive " dozing off " situation even occurs in the gear of abrasion.In the gear transmission structure needing precision positioning, traditional gear transmission structure then can lose precision, it is impossible to meets the normal needs produced.
Summary of the invention
For overcoming the deficiencies in the prior art, the goal of the invention of the present invention is in that providing a kind of eliminates gear backlash device, to solve the phenomenon occurring gap in conventional gears transmission, meets the needs of stable drive between two gears.
For achieving the above object, the gear wheel one of the present invention is fixed on one end of power transmission shaft, and power transmission shaft couples with casing through bearing, and shaft coupling is contained on electric machine main shaft, and the little gear one being arranged on shaft coupling engages with gear wheel one;Described little gear one also engages with gear wheel two, and gear wheel two endoporus is equipped with lining, and described lining is contained in the power transmission shaft other end;Described gear wheel two outer face couples spring one end, and the spring other end couples with thrust bearing, and screw is fixed on gear wheel two through thrust bearing, spring;With loop mapping outside described thrust bearing, described ring, thrust bearing are sequentially sleeved on power transmission shaft.
The little gear two on the opposite of described little gear one engages with gear wheel one, gear wheel two, and little gear two is contained in the bearing in bearing block, and described bearing block couples with casing.
Described little gear one, little gear two, gear wheel one, gear wheel two are angular wheel, and its module is identical.
Described spring is three compression springs, and three springs are uniform along gear wheel biend.
The present invention is compared with prior art, due to spring act on always with on gear wheel two, the little gear one being engaged with is made to be in engagement all the time with gear wheel one, eliminate gear clearance, original precision transmission can be always maintained between gear run, solve the problem owing to gear long-term work backlash occurs and makes outfan lose original transmission accuracy.Simple in construction, convenient and practical.
