Abstract
Axial relative movement of an auxiliary member (30) and a hub body (22z) is performed, the hub body (22z) and an inner race (21) are combined with each other in an axial direction, and a part of the hub body (22z) deformed by a blade (33) of the auxiliary member (30) is disposed inside an engagement concave portion (26) of the inner race (21).
Claims9
A method of manufacturing a staking assembly comprising:
- preparing a first member, a second member including a concave portion and a hole allowing the first member to be inserted thereinto, and an auxiliary member;
- moving the auxiliary member and the first member relatively in an axial direction and including (a) combining the first member with the second member in the axial direction in accordance with the axial relative movement and (b) forming a convex portion engaging with the concave portion in accordance with the axial relative movement in the first member by the auxiliary member;
- and
- forming a staking portion with respect to the second member in the first member.
