Abstract
The utility model relates to a speed reducer, in particular to a worm gear speed reducer with a worm positioning mechanism. The worm gear speed reducer comprises a box, a worm is inserted into the box, a bearing is sleeved on the worm and is fixed to the box through a bearing end cap, and the outer side of the bearing and the worm are positioned through a positioning nut. The worm gear speed reducer with the worm positioning mechanism is simple in structure, high in radiating performance 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 worm-gear speed reducer with the worm screw positioning means.
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, provides a kind of and improves the transmission in working life stably with the worm-gear speed reducer of worm screw positioning means.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of worm-gear speed reducer with the worm screw positioning means, comprise casing, be plugged with worm screw in described casing, on described worm screw, cover has bearing, described bearing fixes by bearing (ball) cover and casing, and locate mutually by setscrew nut and worm screw in the outside of described bearing.
As preferably, locate mutually by sleeve and worm screw the inboard of described bearing, and described bearing (ball) cover seals mutually by oil sealing and worm screw.
As preferably, described oil sealing is by cover plate and the crimping of bearing (ball) cover phase.
As preferably, described bearing (ball) cover fixes by screw and casing, is provided with the adjustment pad between described bearing (ball) cover and casing.
Therefore, the worm-gear speed reducer with the worm screw positioning means that the utility model provides, simple in structure, thermal diffusivity is strong, and transmission steadily improves working life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
