Bearing axial play measurement method, measurement tool and bearing installation method

Abstract

The invention relates to a bearing axial play measurement method, a measurement tool and a bearing installation method. The bearing axial play measuring method comprises the steps that S1, a first bearing and a second bearing are arranged adjacently in the axial direction to form a bearing assembly; S2, a first cushion block is arranged between the outer ring of the first bearing and the outer ring of the second bearing, the height of the first cushion block is a first interval, one axial end of the first cushion block abuts against the outer ring of the first bearing, the other axial end of the first cushion block abuts against the outer ring of the second bearing, and the first cushion block, the inner ring of the first bearing and the inner ring of the second bearing are arranged in a non-contact mode; S3, pressing force is applied to the inner ring of the first bearing and the inner ring of the second bearing of the bearing assembly; the axial distance between the inner ring of thefirst bearing and the inner ring of the second bearing is measured as a second distance; and the axial clearance of the bearing assembly is obtained according to the difference between the first spacing and the second spacing.

Description

technical field [0001] The invention relates to the field of bearings, in particular to a method for measuring the axial clearance of a bearing, a measuring tool and a method for installing the bearing. Background technique [0002] For the gearbox of large machinery, such as the gearbox of the extruder in the petrochemical industry, it is necessary to accurately measure and adjust the axial clearance of the transmission gear bearing of the gearbox during installation and maintenance. [0003] During the measurement, a preload is applied to the bearing assembly. The commonly used technical means in the prior art is to use the weight of a suitable weight to apply force as a pre-tightening force, but it is difficult to find a weight that requires a suitable weight. Sometimes the weight of the shaft on which the bearing is installed is used to compress the bearing to perform the bearing. clearance measurement. [0004] This method is not only complicated to operate, but also ...

AI Technical Summary

Problems solved by technology

[0004] This method is not only complicated to operate, but also difficult to stabilize due to the shaking of the shaft during hoisting, low measurement efficiency and insufficient accuracy, and there is a great safety hazard in the process of hoisting the shaft, and the shaft is not stable during hoisting. The shock force generated by the stability may also cause damage to the bearing
