Background

The coupling is a device for connecting two shafts or a shaft and a rotating part, rotating together in the process of transmitting motion and power and not separating under normal conditions. Sometimes it is used as a safety device to prevent the coupled machine parts from bearing excessive load, and it plays the role of overload protection. The coupling is also called coupling. Mechanical parts for firmly coupling the driving shaft and the driven shaft in different mechanisms to rotate together and transmitting motion and torque. Sometimes also to couple the shaft with other parts (e.g. gears, pulleys, etc.). Usually, the two halves are combined and fastened to the two shaft ends by a key or a tight fit, and then the two halves are connected in a certain way. The coupling can compensate the offset (including axial offset, radial offset, angular offset or comprehensive offset) between the two shafts due to inaccurate manufacture and installation, deformation or thermal expansion in work and the like; and shock mitigation and absorption.

The existing coupler is used for firmly connecting a driving shaft and a driven shaft in different mechanisms to rotate together, but has limited vibration isolation or vibration reduction effect on the operation of high-speed precision rotating machinery, generates large noise, is easy to wear, reduces the transmission effect and prolongs the service life.
