| abstract | (57) [Summary] [Structure] As in (A), the strip-shaped steel plate 1 is subjected to roller forming to form the spur tooth-shaped tooth portion 2. The steel plate 1 on which the tooth portion 2 is formed is cut into a predetermined length, and is circularly bent as shown in (B) to join the both ends to form the tooth portion ring 3. The tooth ring 3 is fitted in the die hole 14 formed in the core 13 of the movable die 12, and the movable die 12 is pressed against the fixed die 16 to be fixed. Molten synthetic resin is injected into the peripheral side. When the synthetic resin is solidified, the movable die 12 is returned and die-cut, and unnecessary portions are cut off to obtain a spur gear in which the steel tooth portion 2 is integrally formed on the outer periphery of the synthetic resin gear body portion. . [Effect] It is possible to manufacture a gear that is lightweight and has excellent tooth strength. A mold with a simple structure that is not restricted by die cutting can be used, and the cost of the mold can be reduced. |
