Peeling test method and device for white layer tissues of rolling bearing

Abstract

The invention belongs to a peeling test method and a peeling test device for white layer tissues of a rolling bearing, which belong to a test method and a test device for the bearing and are used for peeling test of the white layer tissues of the rolling bearing. According to the test method, the adopted technical scheme is that lubricating grease is sealed in a rotary test rolling bearing, and current flows through the test rolling bearing to which radial load is applied; according to the test device, the adopted technical scheme is that: the test rolling bearing into which the lubricating grease is sealed is arranged on an installation shaft; a drive motor drives to apply radial load to the test rolling bearing; the installation shaft is arranged on a sliding seat; the acting force which is applied by a balance acting force device to the test rolling bearing has the same magnitude as the radial load and has the direction opposite to that of the radial load; the test rolling bearing is insulated from the sliding seat; and current of a power supply of the test device flows through the test rolling bearing. The technical problems of low test data consistency, repeatability and reliability, and long peeling time of the white layer tissues and scattered white layer tissues in the conventional peeling test method and the conventional peeling test device for the white layer tissues can be solved.

Description

technical field [0001] The invention belongs to a test method and device for bearings, in particular to a test method and device for exfoliation of white layer tissue of rolling bearings. Background technique [0002] Under special conditions of use of rolling bearings, the peeling off of the white layer tissue caused by fretting friction greatly shortens the service life of the bearings. Some scholars believe that the normal load, relative slip velocity and distance, and material properties have a significant impact on the formation and peeling of the friction white layer; some scholars believe that the formation and peeling of the friction white layer must have a high degree of deformation and rapid heating. and three conditions of rapid cooling. In short, there are many studies on the formation and exfoliation conditions and mechanisms of the white layer, but no breakthrough has been made, and there are no clear research results, and some only put forward some concepts a...
