Abstract

PURPOSE: To prevent the beakage of plastic gear due to the concentration of excess stress, by forming a gear groove on the inner periphery of a plastic gear and by force-fitting and fastening said gear onto a shaft having a similar gear groove.
CONSTITUTION: A plastic united gear 7 has an external gear 8 on the outer periphery and has a gear groove 9 in spline or serration, and these are molded at the same time with injection moulding. On the other hand, on a metal fastening shaft, external gear form such as spline or serration corresponding to the gear groove 9 is cut by rolling processing. Both are force-fitted and fastened by utilizing the elasticity of the plastic gear, and the insertion stress on the inner periphery of the plastic gear is regulated by controlling the gear dimension on the shaft side having a less thermal deformation. Thus, the breakage due to the internal stress of the plastic gear can be prevented easily
