Multifunctional bearing test system

Abstract

The invention provides a multifunctional bearing test device, which comprises a rotation driving system unit, a loading system unit, a high and low temperature environment box, a lubrication cooling system unit and a measurement control system unit, and is characterized in that the loading system unit can control the loading force and the loading waveform of loading heads on an axial loading unit and a radial loading unit, and the high and low temperature environment box can realistically simulate a real temperature environment of a test. The multifunctional bearing test device can simulate service conditions of a test bearing in a test room, realizes performance testing for the test bearing under conditions of given rotating speed, lubrication, temperature, axial load, radial load and circumferential unbalanced impact load and the like, and analyzes influences imposed on the bearing performance by misalignment, poor lubrication, uneven stress and the like through data such as vibration acceleration, abrasive dust amount and the like acquired in the testing process, thereby being capable of more authentically simulating actual conditions of a rolling bearing when being subjected to the radial load, the axial load and the like, and being more reliable, systematic and scientific in service life and reliability evaluation for the test bearing.

Description

technical field [0001] The invention relates to the field of rolling bearing tests, in particular to a test system and a test method for life and reliability tests of rolling bearings. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized. The main function of rolling bearings is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The evaluation parameters of rolling bearings mainly include: maximum speed, rated load and working life. In order to determine the standard of rolling bearing life, the usual practice is to link the life of rolling bearings with reliability. There are many factors that affect the life of bearings, mainly includin...
