Abstract
A bearing assembly is disclosed which addresses the problem of axially retaining a bearing journaled onto a shaft within a casing in an axially compact and technically economic and reliable way by first mounting a retaining plate (6) onto an outer race of the bearing (1). The mounting can be achieved by press fitting onto a shoulder so that the retaining plate can rotate relative to the outer race. The bearing is then journaled onto a shaft (4) and inserted into a compact casing (3) so that the outer race is guided into a housing (2) formed in an end wall of the casing (3). The retaining plate can then be rotated as required to align fastening bosses (7) with holes (8) to be engaged by screws (9) so that the retaining plate us urged axially against the outer race.
Claims17
A method of forming a bearing assembly comprising the steps of:
- first mounting a retaining plate on an outer race of a bearing whereby, when the bearing is subsequently seated in a bearing housing formed in an inside of a casing the bearing is axially retained by the retaining plate which is secured to a wall of the casing by fastening means of the retaining plate;
- the securing step comprising driving fastenings from an outside of the casing through the wall of the casing so as to engage with the fastening means formed in the retaining plate,
- wherein the retaining plate includes a hole extending therethrough that is configured to receive the outer race of the bearing, and a plurality of lips formed around an inside edge of the hole;
- wherein the plurality of lips each have a thickness that is less than a thickness of remaining portions of the inside edge of the hole of the retaining plate;
- and
- wherein the retaining plate is mounted onto the outer race to rotate relative to the outer race.
A method of forming a bearing assembly, said method comprising:
- mounting a retaining plate on an outer race of a bearing that is configured to be seated in a bearing housing formed in an inside of a casing;
- and
- axially securing the bearing in the bearing housing by fastening the retaining plate to a wall of the casing,
- wherein the retaining plate includes a hole extending therethrough that is configured to receive the outer race of the bearing, and a plurality of lips formed around an inside edge of the hole,
- wherein the plurality of lips each have a thickness that is less than a thickness of remaining portions of the inside edge of the hole of the retaining plate, and
- wherein, when the retaining plate is mounted onto the outer race, the retaining plate can rotate relative to the outer race.

- wherein the plurality of lips each have a thickness that is less than a thickness of remaining portions of the inside edge of the hole of the retaining plate, and
- wherein the plurality of lips include a first surface that is coplanar with a second surface of the retaining plate, the first surface abuts a third surface of the outer race of the bearing when the retaining plate is mounted to the outer race of the bearing.
