Abstract
Shaft endplay reducing apparatus for a dynamoelectric machine includes a sheet of resilient material held only by its edges in the machine stator apparatus adjacent one end of the armature shaft. A hardened thrust bearing member is supported by the sheet in abutment with the end of the armature shaft. The sheet of resilient material has low noise transmissibility in tension to reduce noise transmitted from the armature or thrust bearing member to the stator apparatus for radiation to the environment.
