Abstract

The invention relates to a test device, in particular to a dynamic performance test device for angular contact ball bearing retainers. The test device comprises a test main body, an electric main shaft, a frequency converter, a hydraulic loading system, a computer monitoring system and a data acquiring system, wherein the electric main shaft and the hydraulic loading system are respectively connected with the test main body; the frequency converter is connected with the electric main shaft; the electric main shaft provides power for the test main body; the hydraulic loading system provides a test load for the test main body; after the loading of the hydraulic loading system, a signal measured by a measuring device on the test main body and a test parameter of the frequency converter are respectively inputted to the data acquiring system; a signal output terminal of the data acquiring system is inputted in the computer monitoring system; a control signal of the computer monitoring system is inputted in the frequency converter; and the rotational speed of the electric main shaft is controlled through the frequency converter. The test device has the advantages of high reliability, wide measuring range, high sensitivity and resolution, and high response speed.

Description

technical field [0001] The invention relates to a test device, in particular to a dynamic performance test device of an angular contact ball bearing cage. Background technique [0002] Angular contact ball bearings are widely used in mechanical systems such as transmissions, motors, instruments and meters, and household appliances. As a very critical part of this type of bearing, the dynamic performance and reliability of the cage will affect the working performance of the entire bearing. When the structure design of the cage is unreasonable, the manufacturing accuracy is not high, and the operating condition is not good, the dynamic performance indicators such as the dynamic trajectory of the center of mass of the cage, the slip rate, the inclination angle and the skew angle will be extremely unstable. In severe cases, the cage will break or even Bearing failure. Therefore, monitoring the dynamic performance of the cage is very important in analyzing the dynamic character...
