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).
Claims6
A method of manufacturing a staking assembly comprising:
- preparing a first member, a second member including an engagement concave portion and a hole allowing the first member to be inserted thereinto, and an auxiliary member including a protrusion portion;
- combining the first member and the second member with each other in an axial direction;
- moving the auxiliary member and the first member relatively in an axial direction so that a part of the first member is deformed by the protrusion portion of the auxiliary member by the axial relative movement and is disposed inside the engagement concave portion of the second member;
- and
- forming a staking portion with respect to the second member in the first member,
- wherein the combining of the first member and the second member is performed by the relative movement in the axial direction between the auxiliary member and the first member, and
- after the part of the first member is disposed inside the engagement concave portion of the second member, the staking portion of the first member is formed with respect to the second member by using a die that is different from the auxiliary member.
