Self-aligning shaft support
First Claim
1. A guide for supporting a first member in a housing where said first member is capable of rotational and reciprocal movement relative to the housing;
- said guide including a bearing housing having a first angled face, said bearing housing supporting a guide element, said guide element including a central member having an axial passage therethrough which is adapted to sealingly receive the first member to permit said rotational and reciprocal movement, said guide member further including a substantially annular flange element which is received within the bearing housing adjacent the first angled face thereof, said guide member being supported from the first angled face by an annular bearing element, located between one axial face of the flange element and the first angled face of the bearing housing, wherein said bearing housing includes a base having said first angled face and a cap that cooperates with the guide member, said cap including a lower angled face cooperable with a second angled face provided on said base, and wherein the first angled face of the bearing housing and an angled face of the bearing element with which the first angled face is cooperable are of a substantially spherical configuration to enable angular displacement of the guide member relative to said base, and said second and lower angled faces are of substantially spherical configuration to enable angular displacement of the cap relative to the base.

Abstract
A guide to support a shaft such as a pump pull rod (11) which is capable of both rotary and reciprocal motion. The guide prevents any misalignment of rod (11) damaging a seal, e.g. a stuffing box, held in space (24). Guide element (18) has central portion (19) and annular flange (25). Element (18) can move laterally with respect to housing (12) and can also pivot, along with the cap (15) of the housing (12), with respect to the lower portion (14) thereof. The latter is achieved via movements of part-spherical bearing element (28) and similarly shaped faces (26, 37, 38) of housing 9120. Further seals (33, 34) prevents entry of pumped fluid into chamber (13).
