Definition of coupling

  • Release time: 2022-11-07
Coupling refers to a device that connects two shafts or shafts and rotating parts, rotates together during the transmission of motion and power, and does not disengage under normal conditions. Sometimes it is also used as a safety device to prevent the connected parts from bearing excessive load, which plays the role of overload protection.

Coupling is also called coupling. A mechanical component used to firmly connect the driving shaft and driven shaft in different mechanisms to rotate together and transmit motion and torque. Sometimes it is also used to connect the shaft with other parts (such as gears, pulleys, etc.). It is usually composed of two halves, which are respectively connected with keys or tight fits, fastened on the two shaft ends, and then connected by some way. The coupling can also compensate the offset (including axial offset, radial offset, angular offset or comprehensive offset) between two shafts due to inaccurate manufacturing and installation, deformation or thermal expansion during operation; As well as impact mitigation and vibration absorption. [1] 

Most of the commonly used couplings have been standardized or normalized. In general, it is only necessary to correctly select the type of coupling and determine the model and size of the coupling. If necessary, check and calculate the load capacity of vulnerable weak links; When the speed is high, the centrifugal force at the outer edge and the deformation of the elastic element shall be checked, and the balance shall be checked.
