ABSTRACT:
A gear wheel engages a driving worm gear with teeth which have a face with a curved portion. As a result, the circumference of the gear wheel has a portion which extends around the worm gear to increase the tooth contact area between the gear wheel and the worm gear. The gear wheel provides flexible support for the teeth. When a driving load is applied between the worm gear and the gear wheel, the gear wheel is flexed and the stepped portion of the face helps to maintain tooth contact area.
