Traveling wave type ultrasonic motor stator based on diaphragm amplification mechanism

The invention discloses a traveling wave type ultrasonic motor stator based on a diaphragm amplification mechanism, and relates to an ultrasonic motor technology. According to the traveling wave type ultrasonic motor stator based on the diaphragm amplification mechanism, the diaphragm amplification mechanism is installed on the tooth surface of the stator and fixed to the corresponding position through a bolt. According to the hydraulic amplification principle, the area ratio of the large end to the small end is adjusted for amplification, and the original micron-order displacement generated by the stator substrate is amplified by 3-5 times, so that the fitting depth of the friction interface of the stator and the friction material is higher, the driving force in the traveling wave advancing direction is increased, and the energy transmission can be effectively improved; therefore, the transmission efficiency and the mechanical output torque of the ultrasonic motor are improved. 本发明公开了一种基于膜片放大机构的行波型超声电机定子，涉及超
