Abstract
The utility model relates to a speed reducer, in particular to a high-accuracy worm gear speed reducer which comprises a box. An output shaft is inserted into the box, a worm gear is sleeved on the output shaft, two ends of the worm gear and the box are positioned by bearings, the two ends of the worm gear are respectively provided with a lubricating notch, the bearings are positioned above the lubricating notches, and two side walls of an outer ring of the worm gear are respectively provided with an internally inclined inside engaged groove. The high-accuracy worm gear speed reducer is simple in structure and stable in transmission, and the service life is prolonged.
Description
Technical field
The utility model is a kind of speed reducer, particularly a kind of highi degree of accuracy worm-gear speed reducer.
Background technique
Speed reducer of the prior art, the structure relative complex, and also thermal diffusivity is relatively relatively poor, and unstable during use, product is produced certain impact.
Summary of the invention
The utility model is mainly to solve the deficiencies in the prior art, has solved stability not good, and the highi degree of accuracy worm-gear speed reducer of highi degree of accuracy transmission is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of highi degree of accuracy worm-gear speed reducer, comprise casing, be plugged with output shaft in described casing, on described output shaft, cover has worm gear, locate mutually by bearing and casing at the two ends of described worm gear, the two ends of described worm gear are respectively equipped with lubricated notch, and described bearing is positioned at the top of lubrication groove mouth, and the two side of described worm gear outer ring is respectively equipped with and is interior skewed interior engagement groove.
As preferably, the knuckle of the two side ends of the worm gear of left-hand end is arc round angle, and the two side ends of described worm gear seals by oil sealing mutually with casing, and the sidewall of described casing is provided with output flange, and described output shaft extends output flange.
As preferably, described output shaft keeps off mutually by pad and connecing, and described pad is located mutually by back-up ring.
Therefore, the highi degree of accuracy worm-gear speed reducer that the utility model provides, simple in structure, transmission steadily improves working life.
