Abstract
In a process for producing a shaft bearing-bearing housing assembly wherein the shaft bearing has an outer race firmly engaged in the bearing housing, a shaft bearing with a slightly conical outer surface is fitted into a slightly conical receiving bore formed in the bearing housing at an elevated temperature which is higher than the normal operating temperature of the bearing housing and the bearing housing is then permitted to cool down thereby providing for firm engagement of the shaft bearing outer race in the bearing housing.
Claims8
A process for producing a shaft bearing-bearing housing assembly, in particular for a vehicle cooling-water pump, including a shaft bearing having an outer race with an outer surface which is firmly engaged by a surrounding annular surface of a bearing housing, said process comprising the steps of:
- providing a shaft bearing with an outer race having a conical outer surface,
- providing a bearing housing with a conical receiving bore corresponding to the conical outer surface of said shaft bearing outer race and said bearing housing having an annular surface consisting of a material which shrinks upon cooling,
- fitting said shaft bearing into said receiving bore, while said bearing housing annular surface is at a temperature which is greater than a later operation temperature of said assembly, and
- permitting said bearing housing to cool down so as to provide for firm engagement between the shaft bearing outer race and bearing housing annular surface.
