Abstract
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.
Claims18
A method of manufacturing a staking assembly comprising the steps of:
- axially combining a first member with a second member, the second member having a hole into which the first member is inserted;
- and
- forming a staking portion which is a part of the first member deformed radially outward in the first member, the step of forming the staking portion including applying a load including a first load component directed radially inward to a radially outer portion of the first member.
A method of manufacturing a hub unit bearing including an outer race having double-row outer race tracks provided on an inner peripheral surface, a hub having double-row inner race tracks provided on an outer peripheral surface, and a plurality of rolling elements arranged for each row between the double-row inner race tracks and the double-row outer race tracks, the hub including a first hub element and a second hub element in which an inner race track on one side in the axial direction in the double-row inner race tracks is provided on an outer peripheral surface, and the second hub element being externally fitted to the first hub element and suppressing a side surface on one side in the axial direction by a staking portion provided at one axial end portion of the first hub element, the method comprising the steps of:
- axially combining the first hub element with the second hub element;
- forming the staking portion in the first hub element, the step of forming the staking portion including applying a load including a first load component directed radially inward to a radially outer portion of the first hub element.
A staking device comprising:
- a reference axis;
- a pressing die which includes a rotation axis inclined with respect to the reference axis and a processing surface portion formed by an inner surface of an annular concave portion centered on the rotation axis;
- and
- a mechanism which (a) displaces the pressing die in the axial direction of the rotation axis or (b) changes an inclination angle of the rotation axis with respect to the reference axis.
A staking assembly comprising:
- a first member;
- and
- a second member having a hole into which the first member is inserted and axially combined with the first member,
- wherein the first member includes a staking portion for the second member formed by deforming a shaft end of the first member radially outward, and
- wherein the staking portion includes a radially outer portion having a deformed portion at which a load was applied.
