Abstract
The utility model relates to a speed reducer, in particular to a worm gear speed reducer with a fastening oil seal mechanism. The worm gear speed reducer comprises a box body, a gear is inserted into the box body, both ends of the gear are fixed through bearings, an input flange is arranged on the side wall of the box body, the input flange and the head of the gear are sealed via an oil seal, the input flange and the box body are sealed via an O-ring, and the input flange and the box body are fixed via a bolt. The worm gear speed reducer with a fastening oil seal mechanism has simple structure, strong sealability, stable transmission and prolonged service life.
Description
Technical field
The utility model is a kind of speed reducer, particularly a kind of worm-gear speed reducer with fastening oil sealing mechanism.
Background technique
Speed reducer of the prior art, the structure relative complex, and also sealing is relatively poor relatively, and unstable during use, product is produced certain influence.
Summary of the invention
The utility model mainly is to solve the deficiency that exists in the existing technology, and it is not good to have solved stability, and a kind of worm-gear speed reducer with fastening oil sealing mechanism that improves the good airproof performance in working life is provided.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of worm-gear speed reducer with fastening oil sealing mechanism; Comprise casing, be plugged with worm screw in the described casing, the two ends of described worm screw fix through bearing; Described wall box is provided with input flange; Described input flange seals through oil sealing with the head of worm screw mutually, and described input flange seals through O type circle with casing mutually, and described input flange and casing fix through bolt.
As preferably, the bearing in described left side keeps off mutually through back-up ring with worm screw and connecing.
Therefore, the worm-gear speed reducer that the utility model provides with fastening oil sealing mechanism, simple in structure, sealing is strong, and transmission steadily improves working life.
