ABSTRACT:
A self-aligning bearing for a 0.5 kW PMDC electric motor has a bearing member having a cylindrical inner surface for receiving a rotatable shaft and an outer surface comprising a first external, part-spherical, surface-of-revolution and a second external surface-of-revolution comprising a first part extending inwardly from the first external, part-spherical, surface-of-revolution and a cylindrical second part extending from the first part. A housing has a convergent end defining an internal surface of revolution which engages the first external, part-spherical, surface-of-revolution and encloses a retainer engaging the first part of the second external surface-of-revolution. The housing also encloses a support ring which holds the retainer in place and has a radially inner part which surrounds the second part of the second external surface-of-revolution with a clearance space. The support ring thereby limits tilting movement of the bearing member about axes perpendicular to the axis of the bearing member.
