Abstract: A structure for fixing a thrust roller bearing interposed between a shaft and a housing rotating relative to one another comprises a race rest, provided on either the shaft or the housing, for supporting the thrust roller bearig in an unmoved state in the axial direction of the shaft and the housing, and a projection provided at the inner side of an inner race of the thrust roller bearing or the outer side of an outer race of the thrust roller bearing. The race rest has a recess by which the projection is locked to prevent the race and the projection from coming off. The recess can be provided generally in the middle of the face of the rest race whereby the inner or outer bearing will contact the face of the rest race in at least two positions to thereby hold the races stably. A spacer can also be provided between the shaft and the race having the projection to reduce the width of the recess whereby different sized thrust roller bearings can be fixed by the structure.

Abstract: A rolling bearing (12) is arranged to support a shaft (10) rotatably in a housing (13). In order to make simple mounting and dismounting of the bearing (12) possible this is first fitted with a loose fit to the shaft (10), whereupon the shaft (10) is caused to expand thus that an interference fit is obtained at the same time as desired preload can be obtained in the bearing (12). The invention is intended to be applied particularly when mounting a drill head to a tunnel drilling machine.
