Abstract

PURPOSE: To perform reliable power transmission with the shaft at the plastic gear section thus to prevent the stress crack by fitting a washer over the shaft of plastic gear then fitting said washer and the shaft through a key.
CONSTITUTION: The plastic gear 1 has the shaft fitting hole 2 and key groove 2a is made in said hole 2. While the metallic washer 3 has a central through-hole 4 and key groove 4a is made in said through-hole 4. The washer 3 is fitted and adhered to the recess 1a made in the side of plastic gear 1 such that the through-hole 4 and the key groove 4a are matched with the shaft fitting hole 2 and the key groove 2a. Since the shaft 8 penetrates through the shaft fitting hole 2 and the through-hole 4 and engages with the key grooves 2a, 4a, the force produced at the key groove when transmitting the torque between the plastic gear 1 and the shaft 8 can mostly received by the key groove 4a in the rigid washer 4.
