Abstract
The utility model relates to a speed reducer, in particular to a flange sealing mechanism for a gear worm speed reducer. The flange sealing mechanism comprises a case body, a worm is arranged in the case body, an input flange is arranged on the side wall of the case body, the worm penetrates through the input flange, the input flange is fixed with the case body, the input flange and the worm are sealed by an oil seal, the input flange and the case body are sealed through an O-shaped ring, a bearing is sleeved on the worm, and the bearing and the input flange are connected in a touching way. The flange sealing mechanism for the gear worm speed reducer has simple structure, high installation accuracy and good using effect.
Description
Technical field
The utility model patent relates to a kind of speed reducer, relates in particular to a kind of flange seal mechanism that is used for worm-gear speed reducer.
Background technique
Flange 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 flange 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 flange seal mechanism that is used for worm-gear speed reducer comprises casing, is provided with worm screw in the described casing; The sidewall of described casing is provided with input flange, and input flange is crossed in described worm screw cross-under, and described input flange and casing fix; Described input flange seals through oil sealing with worm screw mutually; Seal mutually through O type circle between described input flange and casing, be with bearing on the described worm screw, described bearing touches with input flange mutually.
The blue good airproof performance of this structure input method, operational effect is outstanding.
As preferably, the afterbody of described worm screw places in the input flange, and described input flange and casing fix through screw.
Therefore, the flange 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.
