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 two shafts caused by inaccurate manufacture and installation, deformation or thermal expansion in work and the like, and can alleviate impact and absorb vibration.
