BENDING ENGAGEMENT-TYPE GEAR DEVICE

摘要

PURPOSE: A bending engagement type gear apparatus is provided to enlarge load torque by avoiding the interference of a tooth form of an internal and an external gear for deceleration and to control bending stress by the deformation of the external gear. CONSTITUTION: A bending engagement type gear apparatus comprises an internal gear and an external gear for deceleration, and a vibration body(104). A circumference shape of the vibration body forms so that the internal gear and the external gear for deceleration are engaged. A first curve part(FA), a second curve arc part(SA), and a third curve arc part(TA) are respectively connected. A vibration body bearing having a plurality of rolling elements is arranged between the vibration body and the external gear for deceleration.
