The coupling is also called coupling, and is used for firmly connecting a driving shaft and a driven shaft in different mechanisms to rotate together and transmitting mechanical components of movement 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. 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.
