Abstract:
A hub ( ) includes a spindle ( ) which projects through a housing ( ) and rotates relative to the housing ( ) on a bearing ( ) that is located between the spindle ( ) and the housing ( ). The bearing ( ) has two sets of raceways ( ) that are oblique to the axis x, and in addition rolling elements ( ) arranged in two rows between the sets of raceways ( ). The inner raceways ( ) that fit around the spindle ( ) and have back faces ( ), with the back face ( ) for one of the races ( ) being against a shoulder ( ) from which the spindle ( ) projects. Initially, the end of the spindle ( ) projects straight beyond the back face ( ) of the outer raceâindeed, so that the races ( ) can be installed over the spindle ( ). But once the housing ( ) and races ( ) are in a position around the spindle ( ), the projecting end portion of the spindle ( ) is deformed radially and axially in a rotary forming operation such that it transforms into a formed end ( ) that lies behind back face ( ) of the race ( ). With the two races ( ) between the formed end ( ) and the shoulder ( ).
