Abstract

PURPOSE:To eliminate a drop and a sag almost completely and to perform working with good size precision by making a tooth part thinner than a joint part when a ring blank material is worked plastically. CONSTITUTION:A pulse gear 1 is formed in a ring shape, the joint part 2 for a fitting-side member is formed at the peripheral part of its one end, and an almost corrugated part 3 where internal teeth 4 and external teeth 5 continue alternately is formed at the other-end peripheral part. This pulse gear 1 is formed by working the ring blank material plastically. Then, the thickness t1 of the internal teeth 4 of the teeth part 3 of the pulse gear 1 and the thickness t2 of the external teeth 5 are thinner than the thickness t3 of the joint part 3. Consequently, the blank material spreads to every outer of the tooth part and neither a drop nor sag is almost eliminated, so the gear is worked with good size precision.
