Abstract
A two-piece annular bearing ring seat with an annular concave spherical inside surface is adapted to slidably receive a spherical outer surface of a bearing ring. An annular strap having a coefficient of thermal expansion higher than the coefficient of thermal expansion of a bearing housing holds the bearing ring seat and annular strap together as a subassembly. The subassembly can be press fit into the housing to provide a housed self-aligning bearing.
Claims8
An insert for a housed self-aligning bearing assembly in combination with a bearing, the combination comprising:
- a bearing ring having a spherical outer surface;
- a multi-piece annular bearing ring seat with an annular concave spherical inside surface slidably receiving the spherical outer surface of the bearing ring;
- and
- an annular strap mounted on the bearing ring seat such that the bearing ring seat and annular strap are held together as a subassembly.
