Thrust washer

Abstract

The invention relates to the technical field of thrust washers, in particular to a thrust washer which comprises an inner ring, the inner ring is in an annular plate shape, the inner diameter of the inner ring is equal to the outer diameter of a spline shaft, and the outer diameter of the inner ring is not smaller than the outer diameter of an installed axial steel wire check ring; the outer ring is in an annular plate shape, the inner diameter of the outer ring is not smaller than the outer diameter of the installed axial steel wire check ring, and the inner wall of the outer ring is connected with the outer wall of the inner ring; through sliding connection between the outer ring and the inner ring, the outer ring moves up and down relative to the inner ring of the thrust washer, disassembly and assembly of the steel cable baffle ring for the shaft are greatly improved, and the steel cable baffle ring for the shaft has the advantages of being efficient, convenient to operate, economical and practical; by means of the lever structure, the power arm is larger than the resisting arm to form a labor-saving lever, a worker applies certain force to the blocking piece through the labor-saving lever, so that the steel wire check ring for the shaft is opened, and the labor intensity of the worker for disassembling the thrust washer is relieved.

Description

technical field [0001] The invention relates to the technical field of thrust washers, in particular to a thrust washer. Background technique [0002] A thrust washer is an annular plate or two semi-annular plates usually used with radial sliding bearings to bear axial loads, and is usually used in mechanical devices such as clutch devices, transmissions, gear mechanisms or compressors, so that it can Withstand the axial force and prolong the service life of the mechanical device. [0003] Since the thrust washer is installed on the lower part of the steel wire washer for the shaft and the upper end of the thrust washer is engaged with the steel wire retaining ring for the shaft, the staff needs to smash the thrust washer downwards to separate it from the steel wire retaining ring for the shaft, and then The thrust washer can only be removed after the steel wire retaining ring for the shaft is removed; when installing, the thrust washer must be installed on the shaft first,...

AI Technical Summary

Problems solved by technology

[0003] Since the thrust washer is installed on the lower part of the steel wire washer for the shaft and the upper end of the thrust washer is engaged with the steel wire retaining ring for the shaft, the staff needs to smash the thrust washer downwards to separate it from the steel wire retaining ring for the shaft, and then The thrust washer can only be removed after the steel wire retaining ring for the shaft is removed; when installing, the thrust washer must be installed on the shaft first, then the steel wire retaining ring for the shaft should be installed on the shaft, and then the thrust washer should be knocked upwards , so that it is clamped on the steel wire retaining ring for the shaft. The whole working process is cumbersome and laborious, which seriously affects the work efficiency.

[0004] Although the existing technology can disassemble and assemble the thrust washer, the process is very time-consuming and labor-intensive, which affects work efficiency
