Abstract
This paper use sensor to diagnose antifriction bearings’ vibration signal for failure examination and diagnosis. It can study different kinds of vibration signals of different bearings which expressed out. This text mainly take the diameter of antifriction bearings are 50mm and 60mm for example to design the experiment pedestal. It contains motive source, gearbox, transfer device and charge equipments. Its’ work principle is to gather vibration signals of the examined points by sensor when antifriction bearing is wheeling, and then draw a frequency chart, then compare with the already built database. Analyze where the vibration value is increased, then judge the failure places and kinds. The pedestal can show more about the discipline of failure diagnosis, especially about the subject of antifriction bearings’ failure diagnosis. And acquaintance the importance of failure diagnosis subject.
