Abstract
A hub main body (13z) is supported by a support portion (18). At least one block (22) is engaged with a stationary flange (6) of an outer ring (2). As a support plate (21) rotates, the outer ring (2) rotates. A caulking portion (16) is formed by pressing a pressing die (20) on a cylindrical portion (31).
Claims16
A rotary caulking device comprising:
- a support portion including a reference axis;
- an annular support plate which is supported to be able to move close to and away from the support portion and which can be driven to rotate about a central axis coaxial with the reference axis;
- a rotary drive unit including blocks which are supported at one or more places of a circumference of the support plate to be able to be displaced in an axial direction thereof;
- and
- a pressing die which is supported to be able to perform a rotating motion about a main axis coaxial with the reference axis, and is rotatably supported about a rotation axis inclined relative to the main axis.
2 more elements
A rotary caulking device used in manufacturing a bearing unit, comprising:
- a base which supports a unit main body of the bearing unit;
- a pressing die which is configured to perform a caulking motion relative to the unit main body to which an inner ring is attached;
- and
- an adapter via which an outer ring moves around an axis of the unit main body;
- wherein the adapter includes an adapter main body, and at least one block which is held in the adapter main body, and is disposed to be movable in an axial direction of the unit main body relative to the adapter main body.
2 more elements
A method of manufacturing a hub unit bearing, comprising:
- supporting a hub main body;
- and
- caulking the hub main body to which an inner ring is attached;
- wherein the caulking includes:
- pressing a pressing die on the hub main body while the pressing die rotates;
- and
- moving an outer ring around an axis of the hub main body via an adapter, and
- the adapter includes:
- adapter main body;
- and
- at least one block which is held in the adapter main body, and is disposed to be movable in an axial direction of the hub main body relative to the adapter main body.
