Abstract
A bearing closure assembly for a dynamoelectric machine (e.g., a fractional horsepower motor) is provided which reduces bearing contamination from both airborne dirt and water and which reduces subsequent bearing failure, but which permits increased manufacturing tolerances thus lowering costs. The assembly includes a surface (e.g., a wall) perpendicular to the shaft of the motor having a central opening in it for passage of the shaft. The shaft opening through the surface is defined by a flange integrally formed with the surface. The flange extends axially of the shaft for a substantially greater distance or dimension than the radial clearance between of the shaft and the flange. The closure assembly is also adapted to function as a keeper for a mounting hub ring which in turn enables the dynamoelectric machine to be intermounted to its intended application.
