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 absorption. Most of the commonly used couplings are standardized or standardized, and generally, only the type of the coupling needs to be correctly selected and the model and the size of the coupling need to be determined. If necessary, the vulnerable weak links can be checked and calculated for the load capacity; when the rotating speed is high, the centrifugal force of the outer edge and the deformation of the elastic element need to be checked, balance check is carried out, and the like.
