ABSTRACT:
A bearing retainer for use in a dynamoelectric machine having a rotating shaft and a bearing having a passage therethrough for rotatably receiving the shaft and being positioned within a bearing seat, includes inner and outer concentric support elements. The inner support element defines a thrust portion. Each of the inner and outer support elements defines a plane. A plurality of connectors extend between and connect the inner and outer concentric support elements. The connectors are configured so as to support the inner support element in concentric relation to the outer support element and to support the inner and outer support elements such that the planes defined thereby are non-coplanar with one another. A plurality of bearing load support projections extend inwardly from the outer concentric support element. The support projections extend inwardly a distance so as to define a gap between an end of each projection and the inner support element.
