ABSTRACT:
A rotary assembly includes a shaft, a housing, and a bearing interposed between shaft and housing to provide radial support while also permitting relative rotation.
The invention permits optimum operation of the bearing, by permitting the bearing to be self-positioned even though slightly out of alignment with either the shaft or the housing, or both.
This is accomplished by providing a radial space between the bearing and the shaft or housing; placing a generally ring-shaped compensating member in circumferential engagement with the associated cylindrical surface of the shaft or housing; providing a longitudinal taper on the outer surface of the associated end of the bearing; and then placing the tapered surface of the bearing in overlapping engagement with the compensating member and resiliently urging the bearing and the compensating member axially together so as to provide a firm support both radially and axially for the bearing.
In the complete rotary assembly a radial space is preferably provided adjacent both the shaft and the housing, and separate inner and outer compensating members are utilized, one for the shaft and one for the housing.
