Method of manufacturing staking assembly, method of manufacturing hub unit bearing, staking device, staking assembly, and method of manufacturing vehicle
An application position of a processing force directed radially outward is continuously changed in the circumferential direction of a cylindrical portion ( 25 ) while applying the processing force to a part of the cylindrical portion ( 25 ) of a hub main body ( 21 ) in the circumferential direction. An application position of a processing force directed radially inward is continuously changed in the circumferential direction of a staking portion intermediary body ( 41 ) while applying the processing force to a part of the staking portion intermediary body ( 41 ) in the circumferential direction.
1. A method of manufacturing a staking assembly comprising:
providing a pressing die having a first processing surface portion and a second processing surface portion and a rotation axis that is inclined with respect to a reference axis, the second processing surface portion being located radially outward with respect to the first processing surface portion;
axially combining a first member with a second member in a first direction which is along the reference axis, the second member having a hole with a center portion defining the reference axis and into which the first member is inserted; and
forming a staking portion which is to be a part of the first member deformed radially outward to cover an end portion of the second member,
the forming of the staking portion including:
applying a load including a load component that is directed radially outward toward the first member, the load being applied by using the first processing surface portion of the pressing die; and
applying another load including another load component that is directed radially inward toward a radially outer portion of the first member, the another load being applied by using the second processing surface portion of the pressing die,
wherein the applying the another load includes, while a part of the first processing surface portion faces radially outward and a part of the second processing surface portion faces radially inward, displacing the pressing die in an axial direction of the rotation axis.
2. The method according to claim 1 ,
wherein the forming of the staking portion includes circumferentially moving a position in which the another load including the another load component is applied to the first member.
