Problems solved by technology

For many principle prototypes of ultrasonic motors, due to the lack of finalization, when the preload is applied in the prototype experiment, it is easy to have uneven force on different stress-bearing parts of the stator, and the magnitude of the applied force is not easy to measure, which affects the output performance of the motor.

Abstract

The invention discloses a pre-pressure applying device for a floating self-balancing ultrasonic motor, which includes a bottom plate and a pressure sensor. The bottom plate is provided with a positioning hole, and the positioning hole is set opposite to the flange hole of the stator of the ultrasonic motor; the lower end of the pressure sensor is The threaded rod passes through the compression spring and the flange hole in turn and falls into the corresponding positioning hole; the threaded rod at the upper end of the pressure sensor is fitted with a pressure plate; a pre-tightening bolt is set in the middle of the pressure plate, and the ultrasonic motor is adjusted by tightening the pre-tightening bolt. The stator applies preload evenly to ensure that the preload received by different parts of the stator is equal and measurable.

Description

technical field [0001] The invention belongs to the field of ultrasonic motors, in particular to a pre-pressure applying device for a floating self-balancing ultrasonic motor. Background technique [0002] In recent years, the linear ultrasonic motor has been greatly developed. The output performance of the motor is not only related to the structural design of the vibrator, but also affected by the preload. Whether the applied preload is uniform and the size is appropriate will affect the performance of the motor. . For many principle prototypes of ultrasonic motors, because they are not finalized, when the preload is applied in the prototype experiment, it is easy to have uneven force on different stress-bearing parts of the stator, and the magnitude of the applied force is not easy to measure, which affects the output performance of the motor. Therefore, it is urgent for those skilled in the art to find solutions for how to realize the uniform application of preload to th...
