Description
Technical field
The utility model relates to technical field of automation in industry, specifically a kind of elimination gear backlash device.
Background technique
In existing industrial automation, most of gear transmission is all by structural member connection for transmission, and two engaging 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 output terminal of drive mechanism cannot keep original precision, and the gear of wearing and tearing even occurs that gear transmission " is dozed off " situation.In the gear transmission structure needing precision positioning, traditional gear transmission structure then can lose precision, cannot meet the normal needs produced.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is 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, gearwheel one of the present utility model is fixed on one end of transmission shaft, and transmission shaft connects with casing through bearing, and coupling is contained on electric machine main shaft, and the small gear one be arranged on coupling engages with gearwheel one; Described small gear one also engages with gearwheel two, and gearwheel two endoporus is equipped with lining, and described lining is contained in the transmission shaft the other end; Described gearwheel two exterior edge face connects spring one end, and the spring the other end connects with thrust bearing, and screw is fixed on gearwheel two through thrust bearing, spring; With loop mapping outside described thrust bearing, described ring, thrust bearing are enclosed within transmission shaft successively.
The small gear two on the opposite of described small gear one engages with gearwheel one, gearwheel two, and small gear two is contained in the bearing in bearing support, and described bearing support connects with casing.
Described small gear one, small gear two, gearwheel one, gearwheel two are angular wheel, and its module is identical.
Described spring is three pressure springs, and three springs are uniform along gearwheel biend.
The utility model compared with prior art, because spring acts on on gearwheel two always, the small gear one be engaged with is made to be in engagement all the time with gearwheel one, eliminate gear clearance, original precision transmission can be kept between gear always to run, solve because backlash appears in gear long-term work and make output terminal lose the problem of original transmission accuracy.Structure is simple, convenient and practical.
