Keilverzahnungselementherstellungsgerät und -Herstellungsverfahren

摘要

A spline member manufacturing apparatus includes a shaving punch, a shaving die, a spline punch, and a stripper. The stripper supports a first surface of a base plate portion and an outer circumferential surface of a boss portion. The shaving punch is advanced relatively, while a material and the stripper are being pressed so that cutout portions are formed in an outer circumference portion of the base plate portion by the shaving punch and the shaving die. The shaving punch is further advanced relatively while the outer circumferential surface of the base plate portion is held by the shaving die, so that a spline portion is formed by inserting the spline punch along the inner circumferential surface of the boss portion.
