A method for joining a ring member, e.g. a bearing inner race ring, to a shaft so that the ring member is primarily prevented from axial motion relative to the shaft involves arranging the ring member over the shaft so that the shaft extends through a bore in the ring member, and applying between the ring member and the shaft a clamping wedge force in which a tapering locking surface acts against a substantially corresponding tapering surface. The device for joining the ring member to the shaft includes a locking member mounted on the ring member and provided with a tapering contact surface that faces towards the shaft. An arrangement is provided for pressing the locking element against a tapering counter surface that is fixed in position relative to the shaft to prevent axial movement of the ring member on the shaft.
A device for fitting a ring member, comprised of an inner ring member half having a tapered surface and an outer ring member half, to a shaft with the shaft extending through a bore of the ring member, comprising at least one locking element mounted on the ring member and provided with a tapering contact surface that faces towards the tapering surface of the inner ring member half, and means operatively associated with the locking element for pressing the tapering contact surface of the locking element against the tapering surface of the inner ring member half to prevent axial movement of the ring member on the shaft.
A device which fits a ring member on a shaft with the shaft extending through a bore in the ring member, the ring member including an inner ring member and an outer ring member, with the inner ring member having a tapering contact surface, the device comprising a locking element movably positioned within a seat in the outer ring member, the locking element being provided with a tapering contact surface that faces towards the tapering surface of the inner ring member, and means operatively associated with the locking element for pressing the tapering contact surface of the locking element against the tapering surface of the inner ring member half to prevent axial movement of the ring member on the shaft.
