ABSTRACT:
A self-aligning bearing assembly particularly suited for use in a fractional horsepower electric motor includes a bearing having a partially spherical outer surface and a central hole for rotatably journaling a shaft therein. A housing defining a generally cylindrical opening having an internal surface which is radially spaced from the bearing, also defines a bearing seat adjacent to and conforming in shape with a portion of the outer surface of the bearing. The housing further includes a lip extending radially inward from the internal surface of the cylindrical opening. A spring bearing retainer of resilient flexible sheet-like material and having a generally planar body is inserted into the cylindrical opening. The retainer includes a plurality of radially deformable projections which extend outwardly from the body and has a central aperture for engagement with a second portion of the outer surface of the bearing. The lip on the internal surface of the housing cylindrical opening is so constructed that as the bearing retainer is moved axially into the opening toward the bearing seat, the projections deform radially inward in the vicinity of the ridge, the retainer body deforms axially and the retainer exerts a force against the lip and resiliently retains the bearing against the bearing seat.
