Abstract
A harmonic drive includes a circular rigid internal gear, a circular flexible external gear, a wave generator, a cover, and a fan blade. The circular flexible external gear is disposed in the circular rigid internal gear, and the wave generator has at least one through hole and is disposed in the circular flexible external gear. The cover and the fan blade are respectively disposed at two opposite sides of the wave generator, and the cover is located in the circular flexible external gear. The cover and the wave generator form an air chamber together, and the through hole and an air flow opening are respectively in communication with the air chamber. The wave generator operates to drive the fan blade to operate. The fan blade rotates to generate an air flow, thus performing heat dissipation on the harmonic drive.
