Harmonic Drive, also called Harmonic Drive gear, harmonic gear, or strain wave gearing,
mechanical speed-changing device, invented in the 1950s, that reduces the gear ratio of a rotary
machine to increase torque. It operates on a principle different from that of conventional speed
changers. Harmonic drive products are unique precision speed reducers playing important roles in
robots, semiconductor manufacturing systems, factory automation equipment and furthermore, in
aerospace equipment that may convey our human dreams.
