Abstract
A mount for a bearing comprising a hub portion having a cylindrical surface defining a seat of a predetermined diametral dimension to firmly support a race ring of the bearing. The mount is made of a molding material having a different longitudinal expansion coefficient than the bearing ring and a spiral cast in the molding material and made of a material having the same longitudinal expansion coefficient as the bearing ring. The spiral is mounted in a predetermined position so that at least a portion thereof forms the surface defining the seat. In the preferred embodiment, the spiral is in direct contact with the bearing ring.
Claims9
A bearing housing which is subjected to varying temperatures for mounting an annular bearing element including a section having a generally cylindrical surface defining a seat of a predetermined diametral dimension in relation to the annular bearing element to firmly support the same and formed of a molding material having a first longitudinal expansion coefficient and a spiral cast in the molding material having at least a portion thereof confronting the annular bearing element when mounted in the seat, said spiral being of a material having a second longitudinal expansion coefficient the same as the annular bearing element and different from said molding material, said section of the bearing housing with the spiral cast therein providing a seat having substantially the same heat expansion coefficient as the annular bearing member.
