Alignment method for realizing grinding of steep-angle bearing outer ring on floor type grinding machine

Abstract

The invention discloses an alignment method for realizing the grinding of a steep-angle bearing outer ring on a floor type grinding machine, which comprises the following steps: grinding a reference arc surface (A) at the joint of an outer-ring race surface (B) and an outer-ring large end face (E) on an outer ring (1) firstly; if the steep angle of the outer ring is alpha degrees, tilting a chuck (3) by an angle of alpha degrees; tightly pressing the outer-ring large end face (E) on a pillar (2) configured on the chuck (3), and preliminarily fixing the outer ring by a pressing plate (5); sucking a magnetometer (6) at the end part of a grinding spindle (7), and enabling a contact probe of the magnetometer to point at the reference arc surface (A); rotating the chuck at a low speed and tapping the outer ring, so that the contact probe of the magnetometer is in a minimum oscillating state; and fastening the pressing plate so as to fix the outer ring. The alignment method disclosed by the invention mainly aims to realize the grinding of an outer-ring race surface on a floor type grinding machine, and then aims to indirectly meet the accuracy requirement for the difference in the wall thickness of an outer-ring small end face, thereby improving the grinding efficiency of the outer ring on the floor type grinding machine.

Description

technical field [0001] The invention belongs to the technical field of bearing grinding, and in particular relates to a method for aligning the outer ring of a large-cone-angle bearing on a floor grinding machine for grinding. Background technique [0002] Large taper angle tapered roller bearings are generally used in workplaces where there is only axial load or where the axial load is greater than the radial load. Because the angle of the raceway surface of the outer ring of the large taper angle bearing relative to the central axis of the outer ring is relatively large, it is beyond the angle grinding range of the electromagnetic centerless grinder, so the grinding of the raceway surface of the outer ring cannot be realized on the electromagnetic centerless grinder. [0003] The grinding of the raceway surface of the outer ring of the large taper angle bearing can be realized on a floor grinder, which is a professional grinder produced by Luozhou ZWZ Equipment Co., Ltd. ...

AI Technical Summary

Problems solved by technology

[0007] 1. The measurement of the wall thickness difference between the raceway surface B of the outer ring and the outer circular surface D of the outer ring requires high accuracy, and human errors are prone to occur;

[0008] 2. If the outer ring is loose during the grinding process, it needs to be aligned and clamped again, and the wall thickness difference between the raceway surface B of the outer ring and the outer circular surface D of the outer ring needs to be re-measured, which will increase the working hours and the efficiency is very low
