Abstract
The utility model relates to a speed reducer, in particular to a worm fixing and sealing mechanism for a worm gear reducer, which comprises a box body. A worm is arranged in the box body, a left bearing is sleeved at the left end of the worm, and a right bearing is sleeved at the right end of the worm. The right end lateral wall of the worm is provided with an input flange, and the input flange is sealed with the worm through an oil seal. The input flange is sealed with the box body through an O-shaped ring, the worm is meshed with a worm wheel in the box body, and the left bearing and the right bearing are respectively fixed with the box body. The worm fixing and sealing mechanism for the worm gear reducer is simple in structure, high in installation precision and good in use effect.
Description
Technical field
The utility model patent relates to a kind of speed reducer, relates in particular to a kind of worm screw fixing seal mechanism that is used for worm-gear speed reducer.
Background technique
Worm screw fixing seal mechanism in the speed reducer of present existing technology, complex structure, and also operational effect is relatively poor relatively.
Chinese patent CN201020627721.2; Disclose a kind of accurate worm-gear speed reducer, comprise casing, end cap and be separately fixed at input flange, the capping of casing both sides, two helical pitch worm gear pairs are set in casing; Wherein two external input shafts of helical pitch worm screw; The two ends of two helical pitch worm screws are bearing in the casing by bearing, and the worm drive output sleeve is between the bearing and capping of two helical pitch worm screws rear end, all be provided with automatic adjustment spring between the bearing of two helical pitch worm screw front ends and the input flange.This complex structure, and sealing effect is poor.
Summary of the invention
The utility model mainly is to solve the deficiency that exists in the existing technology, provides a kind of simple in structure, and the outstanding worm screw fixing seal mechanism that is used for worm-gear speed reducer of using effect.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of worm screw fixing seal mechanism that is used for worm-gear speed reducer comprises casing, is provided with worm screw in the described casing; The left end of described worm screw is with left bearing, and the right-hand member of described worm screw is with right bearing, and the right-hand member sidewall of described worm screw is provided with input flange; Described input flange seals through oil sealing with worm screw mutually; Described input flange seals through O type circle with casing mutually, and described worm screw is meshed with worm gear in the casing, and described left bearing and right bearing fix with casing respectively.
This structure worm screw good sealing effect has promoted performance of products.
As preferably, the outer side wall of described left bearing is provided with back-up ring, and described back-up ring and casing fix.
As preferably, the sidewall of described casing is provided with oil seal cover, the symmetrical distribution of the left end of described oil seal cover and worm screw.
Therefore, the worm screw fixing seal mechanism that is used for worm-gear speed reducer of the utility model, simple in structure, installation precision is high, and using effect is good.
