Background

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 vibration absorption.

When the coupler is machined, violent vibration is generated, the coupler is generally fixed by a clamp, but when the coupler is fixed by the general clamp, the coupler is easy to fall off and shake from the clamp, and the finished product rate of the machined coupler is low.
