Abstract:
A wheel bearing forming assembly for deforming an end of a spindle about an inner bearing member to secure the inner bearing member to the spindle, said assembly comprising:a forming tool rotatably mounted about a rotational axis and having a deformation surface for engaging and deforming the end of the spindle about the inner bearing member with the inner bearing member receiving a deforming force during said deforming of the spindle; a constraining tool movable relative to said forming tool in an axial direction substantially parallel with said axis, said constraining tool having a contact surface adapted to abut an outer surface of the inner bearing member during said deforming of the spindle; and said contact surface of said constraining tool defining an angled chamfer extending outwardly away from said forming tool and said axis for presenting an opposing radial force against the inner bearing member opposite said deforming force such that as said forming tool applies an increased radial deforming force to deform the end of the spindle, said constraining tool moves axially toward the inner bearing member and said angled chamfer applies an increased opposing force opposite said deforming force thereby preventing distortion of the inner bearing member about said rotational axis.
