Abstract: The Authors propose an electromechanical integrated harmonic
piezodrive system. The dynamics behavior of the movable tooth drive has
important effects on its operating performance. Here, the dynamic equations of
the movable tooth drive for the drive system are presented. Using the
equations, the natural frequencies and vibrating modes of the movable tooth
drive are investigated. Results show that five vibrating modes occur for the
movable tooth drive which include system modes, static crown gear modes,
movable tooth modes, translating rotor modes and translating crown gear modes.
Eccentric center, thickness and length of the flexible ring, diameter of the
movable tooth and speed ratio have significant effects on the natural
frequencies of the movable tooth drive and should be selected properly.
Keywords: Electromechanical integrated, harmonic piezodrive, vibrating modes, natural frequency
