Detection of defects at different locations in ball bearings by vibration and shock pulse monitoring

摘要: In the present study, vibrations and shock pulse values of good defective bearings have been measured. Bearings with one defect two defects (with different degrees separation) on outer race used. The position respect to maximum load zone axis was also varied. study shows that it is easier detect when are in zone. vibration levels decrease increase angle between defects. as moved away from position. Shock method showed better detectability compared overall levels. However, at low speed, has not proved be effective higher speeds.
