ABSTRACT:
Auxiliary axial thrust bearing apparatus having a case abuttable on a base at one end with the other end supporting an axial thrust bearing. The case and bearing surround the shaft which is to be axially supported. A sleeve, spring or other spacer lie co-axially of the shaft between the bearing and the load or thrust member secured to the shaft. Axial force on the shaft is supported by the apparatus via the case abutting the base and the bearing abutting the load or thrust member on the shaft. The case has a layer of resilient material lying between the bearing and the case and between the case and the base to permit the case and/or the bearing to move to a position of dynamic balance concentric with the dynamic center of balance of the shaft. The resilient layer also damps vibration. A torque arm may extend from the case to the base to resist angular movement of the case relative to the base and/or the end of the case at the base may be serrated to resist relative angular movement.
