Speed variation mechanism for cam operation has cam driver and follower respectively provided with grooves with ridge number adjusted to obtain desired speed variation between input and output shafts

摘要

A cam driver (24) and a cam follower (30) are respectively provided with grooves (38,66,56,88). The number of ridges in the grooves is adjusted. A desired speed variation between an input shaft (22) and an output shaft (28) is determined.
