Rolling bearing cage slip research experiment system

Abstract

The invention provides a rolling bearing cage sliding research experiment system. The rolling bearing cage sliding research experiment system comprises a test spindle connected with a DC speed regulating motor; the rotating speed of the test spindle is measured through a first speed sensor; the rolling bearing is mounted on the test spindle; the cage is connected with a second speed sensor; radialload is applied to the test spindle through a load applying module and a loading bearing; the first speed sensor and the second speed sensor are connected with a speed acquisition module; the load applying module is connected with a load acquisition module through a force sensor; the DC speed regulating motor is connected with a motor control module to realize measurement on a cage sliding rate.Test research is carried out on the influencing factor of the sliding rate. In order to be applicable to a rolling bearing with a dustproof cover, a concave surface can be processed on the outer ringof the bearing and a strain gauge can be attached, and the rotating speed of the cage is measured through the periodic variation of the strain peak collected by the strain gauge. The above system fills the gap in the domestic technology.

Description

technical field [0001] The invention relates to an experimental system for researching the slipping of a rolling bearing cage, which is used for detecting and studying the slipping of the rolling bearing cage and the influence of various related factors on it. Background technique [0002] Rolling bearings are important components of various construction machinery transmission systems, and their failure or failure directly affects the service life of related construction machinery. In most rolling bearing applications, the operating environment is suitable enough to ensure that the motion between the bearing rollers and the inner and outer rings is pure rolling. In some light-load and high-speed operating conditions, such as aircraft engine main shaft bearings, cage slippage and roller slippage will occur inside the bearing. The relative sliding between the internal components of the bearing will cause friction and wear inside the bearing, and eventually lead Damage to the ...
