EXPERIMENT ON THE CAPABLITY OF DIAGNOSING BALL-BEARING DEFECT

Abstract

The paper presents the experimental results on confident degree of diagnosing defect of ball-bearing by the diagnose-instrument designed in the Lab. of Applied Mechanics-Ho Chi Minh City University of Technology. The experiment is carried out by utilizing reducer-box and model having ball bearing with foreknown conditions. The method of diagnose is based on the character of vibration spectrum.
