Shaft Coupling is an important mechanical device mainly used to connect two shafts or shafts with rotating parts, ensuring that they can rotate together during the transmission of motion and power, and do not detach under normal circumstances. This type of device is sometimes used as a safety device to prevent the connected components from bearing excessive loads and serve as overload protection.
The working principle of a shaft coupling is that when the transmission torque acts on the coupling, it is first transmitted to a shaft sleeve through the driving shaft. When the transmission torque reaches a certain value, the shaft sleeve begins to undergo expansion and contraction deformation, transmitting the torque to the passive shaft sleeve. The passive shaft sleeve rotates synchronously, thereby transmitting torque to the passive shaft. When the transmission torque disappears, the coupling returns to its original state and prepares for the next transmission.
The structure of a shaft coupling is usually composed of two halves, which are connected by keys or tight fits, and fastened at the ends of the two shafts. Then connect the two halves together through some means (such as bolts, pins, etc.). In addition, the coupling can also compensate for the displacement (including axial displacement, radial displacement, angular displacement, or comprehensive displacement) between the two shafts due to inaccurate manufacturing and installation, deformation during operation, or thermal expansion, as well as mitigate impacts, absorb vibrations, and other functions.
