Test Rig - Analysis of Antifriction Bearing Under Different Conditions · 模型 85450
Rolling element bearing is a most critical part of any rotating machinery. The machine could be unsafe if any fault occurs in the bearing elements due to fatigue, manufacturing errors and operating conditions. Due to sudden failure of bearing the machine may cause serious accident, economical loss and time. Therefore, it is necessary to predict the faults in bearing well in advance preventive maintenance of machinery. The vibration based condition monitoring is most effective method for identifying fault in the bearing during its operation. In this project a test rig has been designed and developed for vibration measurement of shaft-rolling bearing system. The development of test rig includes design and manufacturing of shaft, selection of support and test bearing along with suitable pedestal, selection of belt, pulley and motor. The vibrations data has been captured by accelerometer for test bearing in presence of normal and defective bearing outer raceway. The measured vibrations has been analyzed in frequency domain to predict the fault characteristics. The vibrations generated by bearing depends on bearing geometry, load and shaft speed. It has been also study the effect of defect size, load and shaft speed on vibration response of healthy and defective bearing.
