Rolling bearing accelerated life testing machine

This paper summarizes the status and development of rolling bearing accelerated life testing machine and the test technology. Discusses the design of life testing, analysis and processing, the life test data. In the eleven five China bearing industry development planning, key requirements carried out to improve the bearing life and reliability engineering technology research. Low cycle load, high speed bearing ,the traditional bearing life test method of high speed, high cost and reliability of test results. And strengthen test while maintaining contact fatigue failure mechanism of the same premise. Shorten the test time.

Reduces the test cost, thus speeding up the development cycle in the product and improve the pace, angular contact thrust ball bearing ,so the accelerated bearing life test has attracted more and more attention, research and application.
