The design of the rolling bearing fault test bench

Abstract In the design of the rolling bearing fault test bench , there are some following requirements : 1、Design the rolling bearing fault test bench；2、Complete the drawing of parameters about the bearings and the bearing basic；3、Determine the various parts of the platform；4、The platform can simulate several typical faults of rolling bearings and achieve the fault simulation and testing by replacing several typical faults bearing 。

The design of the platform focus on four typical bearing failure about fatigue, wear, plastic deformation and corrosion, achieve fault simulation and testing by simulating these four typical bearing failure。 And there are several innovations in this platform：1、The Bearing basic is easy to disassemble, and can do experiment of the different bearing fault；2、The speed of shaft is adjustable, the aim of it is to study the impact on the speed of rolling bearings faults；3、Test bench is designed so that it can be easily mounted on vibration, speed, power and other sensors in order to obtain a true test signals。

There are 28 figures and 30 references in this paper。
