Axial play measurement tool for angular contact ball bearing

Abstract

The invention relates to the field of bearing parameter measurement instrument, specifically an axial play measurement tool for an angular contact ball bearing. The tool comprises a rack, a dial indicator, a bearing outer ring fixing mechanism, and a bearing inner ring axial force applying mechanism. The rack comprises a horizontal pedestal and a vertical column fixed on the horizontal pedestal, wherein the upper end of the vertical column is provided with a clamp for clamping the dial indicator. The bearing outer ring fixing mechanism comprises an upper fixing ring and a lower fixing ring, which are set coaxially. The lower fixing ring is fixedly connected with the central part of the vertical column, and the upper fixing ring is fixedly provided with a casing pipe which can slide on thevertical column. The bearing inner ring axial force applying mechanism comprises a pressing-down block and a jacking block, wherein the pressing-down block is a cylinder corresponding to the externaldiameter of the inner ring of a bearing, and the bottom of the jacking block is connected with a telescoping end of an electric push rod which is vertically set through the pressure sensor. A cylinderend of the electric push rod is fixed on the horizontal pedestal. The tool is simple in structure, is convenient to operate, and can precisely measure the axial play of the angular contact ball bearing.

Description

technical field [0001] The invention relates to the field of bearing parameter measuring instruments, in particular to an axial clearance measuring tool for angular contact ball bearings. Background technique [0002] Angular contact ball bearings are rolling bearings that can carry both axial and radial forces, and are widely used in mechanical transmission equipment. Axial clearance is an important parameter of angular contact ball bearings, which reflects the production level of angular contact ball bearings, and the force limit of bearings can be calculated according to axial clearance, which has important guiding significance for bearing selection. [0003] In the prior art, the axial clearance measurement method for angular contact ball bearings is generally to fix the outer ring, and then use a crowbar to pry the inner ring to generate axial displacement. The difference between the two limit displacements of the inner ring is the angular contact ball bearing. Axial c...

AI Technical Summary

Problems solved by technology

In this measurement method, it is difficult to control the strength of the crowbar to pry the inner ring. If the force is too large, the bearing fittings will be deformed, and the measured axial clearance will be too large; if the force is too small, the inner ring will not reach the limit. Position, the measured axial clearance is too small, which cannot accurately reflect the real performance of angular contact ball bearings
