摘要: A steering rack meshes with a pinion rotatably driven by the input shaft of a steering gear constituting an automotive steering device. The steering rack is provided with a an axially extending rod part of round cross section, and a plurality of rack teeth formed on a radial one side surface of an axial portion of the rod part, the rack teeth meshing with the pinion. At least one dummy tooth is formed in portions that are axial parts of the rod part and are adjacent to both axial sides of the plurality of rack teeth. The dummy tooth has a tooth height less than the rack teeth and does not mesh with the pinion.

摘要: The inspection device of the swing forging apparatus includes an inspection tool and a laser irradiation surface. When inspecting the swing forging apparatus, the inspection tool is supported to the head to which the processing roll is not supported, with a substantially same condition as the processing roll, and the inspection tool has a function of emitting a laser beam onto a central axis of the inspection tool. When inspecting the swing forging apparatus, the laser irradiation surface is arranged so that a relative position of the laser irradiation surface to the head in an axial direction of the head can be changed and the laser beam can be irradiated to the laser irradiation surface.

摘要: A method of manufacturing a rotating bearing unit includes to cause one end surface in the axial direction of the forming punch (46), formed by combining a plurality of punch elements (46, 46) divided in the circumferential direction, which are displaceable in the axial direction and which are not displaceable in the circumferential direction, and having a processing teeth (44, 44) at one end surface in the axial direction, to face the other end surface of the caulking section (20) in the axial direction. In this state, rolls (30a) are rotated about the central axis (a) of the hub main body (8) while pressing the other end surface of the forming punch (46) in the axial direction with a pressing surface (43) of the roll (30a) having a central axis (β) that is inclined with respect to the central axis (α) of the hub main body (8).

摘要: A steering rack includes a rack shaft (10), a plurality of rack teeth (11a) formed on the rack shaft and each having a tooth trace inclined with respect to a first direction perpendicular to an axial direction of the rack shaft, and a dummy tooth (33a) aligned with the rack teeth and formed on the rack shaft. The dummy tooth (33a) is non-uniformly formed in a second direction parallel to the tooth trace of the rack tooth (11a).

摘要: A plurality of press rolls (33) each having an inclined roll central axis (β) are used. Each of press rolls (33) and a hub ring (22z) are relatively rotated while pressing a roll processing surface portion (34) of each of the press rolls (33) against a plurality of locations of a tubular portion (25) of the hub ring (22z) in a circumferential direction to plastically deform the tubular portion (25).

摘要: A method of manufacturing a hub unit bearing (1) includes the step of applying an axial load to a shaft end of a hub body (21) so that a staking portion (26) for inner races (22a, 22b) is formed in the hub body (21). The load is adjusted based on at least one of first information acquired before applying the load and second information acquired while applying the load.
