Locking assembly ( also known as cone clamping elements, clamping sets, clamping elements,locking devices, locking elements, )  belongs to the category of general mechanical parts. It is often used to connect two shafts (driving shaft and driven shaft) in different mechanisms to rotate together to transmit torque. It is most commonly used to connect pulleys and shafts.The locking assemblies is a keyless connection device. Its principle and purpose is to generate a huge clamping force between the inner ring and the shaft, and between the outer ring and the hub through the action of high-strength tension bolts to achieve a keyless connection between the machine and the shaft.

A coupling is a device that connects two shafts or a shaft and a rotating part, and rotates together during the transmission of motion and power, and does not disengage under normal circumstances. Sometimes it is also used as a safety device to prevent the connected parts from being subjected to excessive loads, playing the role of overload protection.
