International ClassB23P 015/00Foreign Application Priority Data1995-05-10 SEAbstractA method for mounting on a shaft extending through a housing a preloaded rolling bearing assembly incorporating first and second rolling bearings capable of supporting axial load, involves mounting the outer race rings of both bearings in axially fixed positions in the housing, mounting the inner race rings with a shrink fit on the shaft and with rolling bodies disposed between the inner and outer race rings, and introducing in the interface between the inner envelope surface of the inner race ring of the second bearing and the shaft a pressure medium to create a thin medium film in the interface for allowing the inner race ring of the second bearing to be axially displaced on the shaft. An axial force is then applied to the inner race ring of the second bearing and the axial force thus applied is measured. The pressure medium is then drained from the interface between the inner race ring and the shaft when a predetermined axial force is reached, whereupon the axial force is relieved. | |
