Abstract
A harmonic drive mechanism of a wave generator, including a first bearing set, an input shaft, a left end cover, a second bearing set, an output shaft, a key, a bolt assembly, a vibratory hydraulic wave generator assembly, a rigid internal gear sleeve and a flexible external gear. The input shaft which is rotatable is provided on the left end cover through the first bearing set. A part of the input shaft and the flexible external gear are located in the rigid internal gear sleeve. The output shaft which is rotatable is provided on the rigid internal gear sleeve through the second bearing set. An end of the output shaft is connected to the flexible external gear via a key. The vibratory hydraulic wave generator assembly includes a casing, a vibrating plate, a backing plate and a check valve which are located in the flexible external gear.
