Anti-deformation long service life worm gear speed reducing box

Abstract

The invention provides an anti-deformation long service life worm gear speed reducing box and belongs to the technical field of worm and gear transmission. The anti-deformation long service life wormgear speed reducing box comprises a box body which is internally provided with a worm and a worm gear engaged with the worm; the worm gear is fixed to a main shaft which is rotationally connected withthe worm and the box body; the two ends of the worm are rotationally connected with the box body through a first conical roller bearing assembly and a second conical roller bearing assembly; and thetwo ends of the main shaft are rotationally connected with the box body through a third conical roller bearing assembly and a fourth conical roller bearing assembly. The anti-deformation long servicelife worm gear speed reducing box can resist deformation under high-speed rotation, long-time using of a bearing is achieved, and the service life of the whole gear box is prolonged.

Description

technical field [0001] The invention belongs to the technical field of worm gear transmission and relates to a deformation-resistant and long-life worm gear reducer. Background technique [0002] The input end of the worm and the main shaft connected to the worm gear, that is, the power output end, are in rigid contact, and the bearings on the worm and the main shaft are stressed, so the life of the bearing is directly related to the life of the entire worm gear box. [0003] In the prior art, a deep groove ball bearing assembly is used to realize the rotational connection between the worm, the main shaft and the casing. Since there is a tolerance of several wires (usually 2 wires) between the balls of the deep groove ball bearing and the outer and inner rings of the bearing, when the worm and the main shaft rotate at high speed, the deep groove ball bearing will produce a distance corresponding to the tolerance in the radial direction The beating and long-term beating will...

AI Technical Summary

Problems solved by technology

Since there is a tolerance of several wires (usually 2 wires) between the balls of the deep groove ball bearing and the outer and inner rings of the bearing, when the worm and the main shaft rotate at high speed, the deep groove ball bearing will produce a distance corresponding to the tolerance in the radial direction Long-term beating will cause deformation and damage to deep groove ball bearings, and failure of worm gear reducer

To restore the use of the worm gear reducer, it is necessary to disassemble the worm and the main shaft, replace it with a new deep groove ball bearing, and then reassemble, which is time-consuming and laborious, and is not conducive to continuous production
