Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
130 words
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.
Claim 2
Dependent Claim
130 words
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.
Claim 3
Dependent Claim
22 words
A bearing housing as claimed in claim 1 wherein the inner peripheral surface of said spiral directly engages the annular bearing element.
Claim 4
Dependent Claim
22 words
A bearing housing as claimed in claim 1 wherein said annular bearing element engages interiorly of said cylindrical surface of said seat.
Claim 5
Dependent Claim
22 words
A bearing housing as claimed in claim 1 wherein said annular bearing element forms an outer ring of a ball bearing assembly.
Claim 6
Dependent Claim
47 words
A bearing housing as claimed in claim 1 wherein said spiral is made of a steel having a thermal expansion coefficient of about 10-6 and said molding material is a reinforced epoxy plastic having a thermal expansion coefficient about 2 to 4 times greater than said spiral.
Claim 7
Dependent Claim
18 words
A bearing housing as claimed in claim 1 wherein the bearing element and spiral are the same material.
Claim 8
Dependent Claim
25 words
A bearing housing as claimed in claim 6 wherein said spiral and bearing element are made of steel and the said molding material is plastic.
Claim 9
Dependent Claim
19 words
A bearing housing as claimed in claim 1 wherein the spiral includes terminals for connection of electric wires thereto.
Claim 10
Dependent Claim
23 words
A bearing housing as claimed in claim 1 including a thin layer of the molding material between said spiral and the bearing element.
