摘要： A shaft diameter enlarging apparatus and a shaft diameter enlarging method are provided. The shaft diameter enlarging apparatus includes a presser to apply pressure to both ends of a shaft in an axial direction, a load generator to apply alternating load in a direction intersecting the axial direction to an intermediate portion of the shaft, a detector to detect an outer diameter of the intermediate portion being enlarged, along with a compression in the axial direction, through the application of the pressure and the alternating load, and a controller to control the presser and the load generator. The detector includes a contact element arranged to contact an outer peripheral surface of the intermediate portion to detect the outer diameter based on a displacement of the contact element. The controller adjusts the pressure applied by the presser and stops the compression of the intermediate portion, based on the detected outer diameter.

摘要： A method and an apparatus for manufacturing a stepped member are provided. An intermediate portion of a shaft workpiece is radially enlarged while being compressed in an axial direction by applying alternating load to the intermediate portion in a direction intersecting the axial direction in a state in which pressure that compresses the shaft workpiece in the axial direction is applied to both ends of the shaft workpiece. The enlarged intermediate portion of the shaft workpiece is cut in a direction perpendicular to the axial direction so that the shaft workpiece is divided into two stepped members. Each of the stepped members has a shaft portion and a head portion provided at an axial end of the shaft portion, and the head portion has a larger diameter than the shaft portion.

摘要： A composite member includes a metal shaft member, and a fit member having an insertion hole and secured onto the shaft member inserted in the insertion hole. The shaft member includes a receiving portion contacting a first end surface of the fit member, a first radially enlarged portion adjacent to the receiving portion in an axial direction and tightly contacting an inner peripheral surface of the insertion hole, and a second radially enlarged portion adjacent to the first radially enlarged portion in the axial direction and tightly contacting a second end surface of the fit member opposite to the first end surface. The first and second radially enlarged portions are formed by applying a compressive load in the axial direction to the shaft member and an alternating load in a direction intersecting the axial direction to a portion of the shaft member inserted in the insertion hole.

摘要： A sleeve is provided for a partial diameter enlargement in which a portion of a workpiece between a pair of holder units supporting both end portions of the workpiece is enlarged by applying pressure to the workpiece in a direction of an axis of the workpiece while at the same time applying energy to the workpiece in a direction intersecting the axis to form a diameter-enlarged portion between the holder units. The sleeve is provided in at least one of the holder units to support at least one of the end portions of the workpiece in a fitted manner. The sleeve has at least two portions, one of which contacting the diameter-enlarged portion when the partial diameter enlargement is completed, so that only the portion that contacts the diameter-enlarged portion can be replaced.
