Abstract

The bearing has an inner race member and an outer race member. At least one of the race members has two axially separated races. Rolling members are provided in the annular space between the two race members. A permanently plastically deformed means such as a permanently plastically deformed ring separates the facing ends of the axially separated races, and provides a proper axial fit-up.

To assemble the bearing the axially separated bearing races, the deformable ring between them and the rolling members such as balls are placed within an outer race member. A force is then applied against each of the axially separated races to permanently deform the ring. The ring is permanently deformed in a manner to provide a proper axial fit-up of the bearing components.

Claims

1. A method of axially fitting-up a pair of axially separated bearing races forming part of a bearing having a second race radially separated from the pair of axially separated bearing races comprising:

assembling together the pair of axially separated races, rolling members, plastically deformable material, and the second race so that the plastically deformable material is between the facing ends of the axially separated races, and the raceways on the axially separated races are axially spaced from the rolling members;

applying sufficient axial forces against the axially separated races to go beyond the plastic limit of the deformable material to permanently deform said material so that the cross sectional length of the deformable material in the axial direction is permanently reduced, and move the axially separated races toward one another so that the raceways of the axially separated races will become properly axially spaced in relation to the rolling members;

stopping the application of the axial forces; and

permanently holding the axially separated races in the bearing.

2. A bearing comprising:

an inner race member and an outer race member, at least one of said race members having two axially separated races;

rolling members in the radial space between said two race members permanently plastically deformed means separating the facing ends of said axially separated races and providing a proper axial fit-up of the bearing components;

said permanently plastically deformed means having a permanently reduced cross-sectional length measured in the axial direction when compared to the cross-sectional length measured in the axial direction of the permanently plastically deformed means before being made a part of the bearing; and

separate means for holding the two axially separated races and permanently plastically deformed means together.

3. The bearing in accordance with claim 2 wherein:

said plastically deformed means comprises plastically deformable material located between the facing ends of the axially separated races.

4. The bearing of claim 2 wherein said plastically deformed means is a plastically deformed annular ring located between the facing ends of the axially separated races.

5. A method of axially fitting-up a pair of bearing races, at least one of said bearing races having a plastically deformable portion abutting the other bearing race, said bearing races forming part of a bearing having a second race radially separated from the pair of bearing races comprising:

assembling together the pair of separated races, rolling members, and the second race so that the raceways on the pair of bearing races are axially spaced from the rolling members;

applying sufficient axial forces against the pair of races to go beyond the plastic limit of the deformable portion to permanently deform said portion so that cross-sectional length of the deformable material in the axial direction is permanently reduced, and move the pair of bearing races toward one another so that the raceways of the pair of races will become properly axially spaced in relation to the rolling members;

stopping the application of the axial forces; and

permanently holding the pair of races in the bearing.

6. A bearing comprising:

an inner race member and an outer race member, at least one of said race members consisting of a pair of races;

rolling members in the radial space between said two race members, at least one of said pair of races having a permanently plastically deformed portion abutting an axial end of the other of said pair of races and providing a proper axial fit-up of the bearing components, said permanently plastically deformed portion having a permanently reduced cross-sectional length measured in the axial direction when compared to the cross-sectional length measured in the axial direction of the permanently plastically deformed portion before being made a part of the bearing.

7. The bearing of claim 6 wherein each of said pair of races has a permanently plastically deformed portion abutting the permanently plastically deformed portion of the other races of said pair of races.
