Abstract
The utility model relates to a reducer, in particular to a roller bearing mechanism for a worm gear and worm reducer, which comprises a box body. A worm is arranged in the box body, a left roller bearing is sleeved at the left end of the worm, a right roller bearing is sleeved at the right end of the worm, an input flange is arranged on the lateral wall of the box body, one end of the worm extends in the input flange, the input flange and the worm are sealed through an oil seal, and the worm is meshed with a worm gear arranged in the box body. The roller bearing mechanism for the worm gear and worm reducer is simple in structure, high in installation accuracy 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 roller bearing mechanism that is used for worm-gear speed reducer.
Background technique
Roller bearing 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 roller bearing 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 roller bearing 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 the axis of a cylinder that rolls left and holds; The right-hand member of described worm screw is with right roller bearing, and the sidewall of described casing is provided with input flange, and the end of described worm screw extends in the input flange; Described input flange seals through oil sealing with worm screw mutually, and described worm screw is meshed with worm gear in the casing.
As preferably, the described axis of a cylinder that rolls left holds with right roller bearing and casing and fixes, and seals mutually through O type circle between described input flange and casing.
As preferably, described input flange and casing fix through screw.
Therefore, the roller bearing 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.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
