Abstract

PURPOSE:To prevent build-up of both side faces of a gear blank material by inserting said both side faces into the groove part of a grooved collar and force- flowing the build-up of both side faces produced during production to the central direction of the gear. CONSTITUTION:Holders H1, H2 are pressurized, and a grooved collar C1 is inserted until a collar C2 and a template T contact while both side faces of its groove part are allowed to contact with both sides of a gear blank material. The tips of a die roller D1 contact the outside circumference of the gear blank material, and as rolling pressure increases, a tooth profile is gradually formed. At the same instant of the formation of the tooth profile, the build-up of both side faces occurs, but the build-up is force-flowed to the inner side and the central direction of the gear from both side faces of the tooth trace by both side faces of the groove part of the grooved collar C1.
