摘要：
In forming helical splines with stoppers on a rotary shaft, its large-diameter portion is held between a pair of rolling tools, each of which comprises: a helical teeth forming die having inclined teeth; an aligning teeth die having aligning teeth which are aligned with every other inclined tooth when combined with the helical teeth forming die; and a finishing teeth die having finishing teeth which are equal in pitch to the aligning teeth. Under this condition, the shaft is rolled under pressure by moving the rolling tools, to form helical grooves, and communication grooves communicated with every other helical grooves on the large-diameter portion, leaving stoppers between the communication grooves. Hence, the helical splines are formed by one rolling operation, with burrs formed between the spline grooves and the communication grooves being automatically removed.
