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.
Claims8
A bearing assembly comprising:
- a bearing having an outer race for reception in a bearing housing formed in a casing and an inner race to be journaled onto a shaft, wherein
- a retaining plate is mounted onto the outer race before assembly into the bearing housing and provided with fastening means to cooperate with fastening means provided in or on a wall of the casing opposing the retaining plate, the retaining plate is mounted by means of a press action loose fitting clinching lip formed on a circular inside edge of the retaining plate which deforms plastically to engage in a circular groove formed in a circular shoulder in the outer race of the bearing.
