This paper deals with the rib—roller end contact of taper roller hearings from the vibrational point of view in order to diagnose its failure when running under different operating conditions of axial loads, speeds, lubrication, and mounting fits. The dynamic response of an axially loaded tapered roller bearing is obtained experimentally. A test rig is built to investigate the vibrational response of the tapered roller bearings when running under different operating conditions.
The results show that the vibrational response of the tapered roller bearings increases with the axial loading, unbalance, rotational speed, lack of lubrication, grade of fit, and wear of bearing elements.
