Accurate cutting or shaping of internal or external evolute gear teeth - involves tool shaped as globoidal worm gear for plastic deformation by rolling, grinding or cutting

摘要

The system is for prodn. of evolute teeth (3) on a gearwheel (2). A variety of different shaping processes may be used, including plastic deformation by rolling, grinding and cutting with a machine tool. The tool (1) may be shaped as a globoidal worm gear and may conform to given official standards. It may work on internal or external straight or helical teeth and its centre may be displaced from the centre of the gearwheel, and may travel round on a circular path (4). USE/ADVANTAGE - Accurate cutting or shaping of internal or external evolute gear teeth.
