Abstract

The modular ultrasonic clutch and brake mechanism consists of control and power source module, driving element, driven element, support assembly, pre-stress regulator, fixing seat and pedestal. Both the driving element and the driven element have piezoelectric component and contact tightly, so that the load end will rotate synchronously with the motor shaft in use as clutch and will produce braking effect in use as brake. When alternate power source is applied onto the piezoelectric components, the counter-piezoelectric effect of the piezoelectric components will make the combining surface of the mechanism produce mechanism vibration and separation, and this makes the load end stop rotating in use as clutch and the load end produce no braking effect in use as brake.

Description

technical field [0001] The invention relates to a modularized ultrasonic clutch and brake device, which utilizes a piezoelectric element to generate an inverse piezoelectric effect, thereby combining or separating a driving element and a driven element, so as to achieve the functions of a clutch device such as start, stop, and speed change. . Background technique [0002] Known clutch device is of a great variety at present, can be divided into manipulation type and automatic type by its control mode. The functions of the clutch device include starting, stopping, reversing, speed change, or for occasions such as shaft-to-shaft engagement or separation. The types and disadvantages of the clutch device are as follows: [0003] 1. Embedded clutch device: It uses teeth, teeth or keys to transmit torque. There are protruding teeth or teeth on the end faces of its two engaging parts. If the teeth or teeth on the driving element and the driven element are engaged or disengaged f...
