Embodiment Construction
[0025] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0026] Such as Figure 1-Figure 3 As shown, a dust-proof traveling wave type ultrasonic motor pre-pressure rotor system of the present invention includes a central shaft, a motor casing, a rotor and a gland. The motor casing and the rotor are sequentially sleeved on the central shaft, and the motor casing, The rotor is concentrically arranged, and the gland is arranged on the top of the central shaft; the surface of the rotor is provided with a pre-pressing point, and the gland is in contact with the pre-pressing point, and the thickness of the rotor gradually becomes thinner from the center to the outside;
[0027] As a further preference of the present inve...
