Abstract
In order to simplify mounting of the inner ring (5) of one of the bearings (102) of a wheel hub on the associated spindle (1) and in order to perform keying together of this ring and the spindle by means of multiple-lobe--for example three-lobe-machining which can be performed using the same machine for turning the spindle and the ring, this same three-lobe machining operation is such as to involve all or only partly the shoulder (6) of the spindle and involve, in recessed form, the corresponding inner end of the ring (5) intended to rest against this shoulder, so that the said ring (5) may be mounted on the spindle (1) as though these two parts were two normal parts with a round cross-section and therefore without any need for prior relative angular alignment thereof. After these two parts have been engaged together axially, a relative rotation of said parts is performed so as to engage correctly the three-lobe profile (100) of the ring (5) with the corresponding three-lobe profile (10) of the shoulder (6) of the spindle and vice versa and, after this step, the edge (201') for axially locking the said inner ring (5) of the bearing is formed by means of rolling.
