Backlash adjustment method for inlet bearings of rectangular axis speed reducer

Abstract

The invention discloses a backlash adjustment method for inlet bearings of a rectangular axis speed reducer. The backlash adjustment method is applied to a bevel gear component of the rectangular axis speed reducer. The bevel gear component comprises an umbrella gear shaft, two inlet bearings and a bearing block, wherein the inlet bearings sleeve the umbrella gear shaft; the bearing block is used for bearing the inlet bearings; the two inlet bearings are respectively a first bearing and a second bearing; firstly, the umbrella gear shaft and the first bearing are subjected to hot charging; the installed umbrella gear shaft and one side of a shaft head of the first bearing are put into the bearing block; a gasket is put on the combined surface between the first bearing and the bearing block; then the second bearing is installed, and pressed by virtue of a coupling and a pressure plate; the gasket is removed after the overall assembly is ended, thus finishing the overall assembly process. According to the backlash adjustment method, a required bearing backlash can be rapidly and accurately obtained by putting filler gauges (gaskets) with different thicknesses; the operation is simple; the labor workload of an assembler is reduced; the assembly efficiency is improved.

Description

technical field [0001] The invention relates to a technology for adjusting the clearance of an incoming shaft bearing of a right-angled shaft reducer, in particular to a method for adjusting the clearance of the incoming shaft bearing of a right-angled shaft reducer. Background technique [0002] In the assembly of the reducer, a very important step is to adjust the axial clearance of the bearing. Too small bearing clearance will cause the bearing to heat up and jam during operation, and in severe cases, the bearing will fail early; too large bearing clearance The gap will cause the bearing to move back and forth axially under the action of axial force, resulting in noise and vibration. Usually, the bearing part of the input shaft of the right-angle reducer is installed with a pair of tapered roller bearings back to back, and the clearance adjustment is adjusted through the spacer ring or lock nut and the end pressure plate between the two bearings. When adjusting, first pu...
