Embodiment Construction

[0017] Such as figure 1 and figure 2 As shown, an axial clearance measuring tool for an angular contact ball bearing of the present invention includes a frame, a dial indicator 10, a fixing mechanism for the outer ring of the bearing, and an axial force applying mechanism for the inner ring of the bearing.

[0018] The frame includes a horizontal base 1 and two columns 6 vertically fixed on the horizontal base 1. A clip 11 for clamping and fixing the dial gauge 10 is provided on the upper end of one of the columns 6. By clamping or loosening the clip 11 to adjust the height of dial gauge 10.

[0019] The bearing outer ring fixing mechanism includes an upper fixing ring 9 and a lower fixing ring 5 arranged coaxially, and both the upper fixing ring 9 and the lower fixing ring 5 are arranged parallel to the horizontal base 1 . The both sides of lower fixed ring 5 are fixedly connected with the middle part of two columns 6 respectively, and the both sides of upper fixed ring 9 ...

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...
