Coupling refers to a device that connects two shafts or shafts with rotating parts, rotates together during the transmission of motion and power, and does not detach under normal circumstances. Sometimes it is also used as a safety device to prevent the connected components from bearing excessive loads, serving as overload protection.
Couplings are mechanical components used to firmly connect the active and driven shafts in different mechanisms for rotation, and to transmit motion and torque. Sometimes it is also used to connect shafts with other parts such as gears, pulleys, etc. Couplings are often composed of two halves, which are connected by keys or tight fitting, fastened at the ends of the two shafts, and then connected together in some way. Couplings can compensate for offset between two shafts due to manufacturing and installation inaccuracies, deformation during operation, or thermal expansion (including axial offset, radial offset, angular offset, or comprehensive offset); And to mitigate impact and absorb vibration.
Most commonly used couplings have been standardized or normalized, and in general, it is only necessary to correctly select the type of coupling, determine the model and size of the coupling. If necessary, the load capacity of vulnerable weak links can be checked and calculated; When the speed is high, it is necessary to verify the centrifugal force at the outer edge and the deformation of the elastic element, and perform balance verification.
