摘要： A first step of setting a steel material heated to a temperature not lower than an A 1 transformation point on a forming table and a second step of punching a ring-form member from the steel material and thereafter forming and quenching the ring-form member on the forming table are included. A press die (30) is constructed to be dividable into an inner cylinder (30B) and an outer cylinder (30A). In the second step, the ring-form member (2A) is punched from a coil material (2) by pressing a tip end portion of the inner cylinder (30B) and a tip end portion of the outer cylinder (30A) against the coil material (2). The punched ring-form member (2A) is formed and quenched by further pressing a tip end of the inner cylinder (30B) against the ring-form member (2A) while the ring-form member (2A) is held between the outer cylinder (30A) and a forming die (32). A method of manufacturing a rolling bearing ring which achieves a shortened manufacturing process while accuracy in forming of the rolling bearing ring is satisfactorily maintained is thus provided.

摘要： Tapered roller bearings have in many design forms an inner ring, an outer ring and a plurality of tapered rollers which are arranged to roll between the inner ring and outer ring. It is the object of the present invention to propose a method for producing a tapered roller assembly which can be mounted in a particularly simple manner. For this purpose, a method for producing a tapered roller assembly (1) having an inner ring (3) and a roller ring (12) is proposed, wherein the method comprises the following steps: a) providing the inner ring (3), wherein the inner ring (3) has a flanged mounting rim (10) which is produced within a preliminary flanging stage by flanging over an edge region (6) of the inner ring (3); b) mounting the roller ring (12) on the inner ring (3), wherein the roller ring (12) is pushed over the flanged mounting rim (10) onto the inner ring (3); c) flanging over the flanged mounting rim (10) into a flanged rim (15), wherein the flanged rim (15), as a retaining rim, captively retains the roller ring (12); and d) heat-treating the flanged mounting rim (10) before step b) or step c), wherein a hardness of the flanged mounting rim (10) is reduced by comparison with a hardness of a raceway (5) of the inner ring (3). Also proposed is a tapered roller bearing (20) formed with such a tapered roller assembly (1).

摘要： Tapered roller bearings make it possible to deflect both radial loads and axial loads via a bearing. The aim of the invention is to propose a method for producing an inner ring for a tapered roller bearing which is cost-effective but at the same time leads to a sufficiently high quality of the inner ring. For this purpose, a method for producing an inner ring (2) for a tapered roller bearing (2) is proposed in which the inner ring (2) has a raceway portion (13) and a fixed edge portion (14), said method comprising the steps of: providing an inner ring blank (25), the inner ring blank (25) having an unfinished raceway portion (26) and an unfinished fixed edge portion (27), the unfinished fixed edge portion (27) having a larger outside diameter than the unfinished raceway portion (26), and the inner ring blank (25) having a through-opening (28); cold forming the inner ring blank (25) into the inner ring (2) by means of extrusion in a main forming step, wherein the unfinished fixed edge portion (27) is transformed into the fixed edge portion (14) and the unfinished raceway portion (26) is transformed into the raceway portion (13).

摘要： A rotary press device (33) includes a restriction section (36) configured to restrict a motion of a roll (30) around a central axis of a roll (30) against movement of the roll (30) around a central axis of a hub main body (8) during rotary forging. In an example, the restriction section (36) has guide teeth (44) meshed with teeth formed on a processing surface of the roll (30).

摘要： An outer ring 6a for a shell-type radial needle bearing having a cylindrical shape with a bottom is achieved for which fatigue life of the bottom plate section 9a and the continuous section between the bottom plate section 9a and the cylindrical section 8a is improved, as well as the anti-corrosion characteristic of the outer ring 6a is improved and the outer ring 6a can be prevented from coming out of the bearing without an increase in cost. After obtaining an intermediate raw material 35 having a cylindrical section and a bottom plate section from a metal raw material, shot peening is performed on the intermediate material 35 to create residual compressive stress in the surface and surface layer section on the outer surface side of the cylindrical section 8a and the bottom plate section 9a such that the residual compressive stress in the surface layer section on the outer surface side is greater than the in the surface layer section on the inner surface side, and from the surface to a depth of 0.03 mm is 700 MPa to 1600 MPa.

摘要： Provided is a bearing device for a wheel capable of suppressing radial play and allowing firm and easy connection between a hub and an outer ring of a constant velocity universal joint. Axially extending projections are provided on a shaft portion of a joint outer ring, and the shaft portion is press-fitted into a hole of a hub. Through this press-fitting, recesses held in close fit-engagement with the projections are formed by the projections in an inner diameter surface of the hub, forming a recess/projection fit-engagement structure in which the projections and the recesses are held in close contact with each other over an entire f it-engagement region thereof. A press-fitting margin Δd of the projections with respect to the hub and a height h of the projections are set to the following range: 0.3
