 ## Introduction To The Coupling

##### Date:May 27, 2018

A mechanical part used to couple two shafts (active and driven) in different mechanisms to rotate together to transmit torque. In high-speed and heavy-duty power transmissions, some couplings also have the function of damping, damping and improving the dynamic performance of the shafting. The coupling consists of two halves, which are respectively coupled to the drive shaft and the driven shaft. Most of the general power machines are connected to the working machine by means of a coupling.

Folding common terms

1. Parallel deviation: The amount of deviation between the two axes when the two axes are connected.

2. Angle deviation: The deviation angle of the two axes when the two axes are coupled.

3. Axial deviation: The amount of displacement of the two axes in the axial direction when the two shafts are coupled.

4. Coupling torque: When a force drives a shaft to rotate, the force of the lead is multiplied by the shaft radius to be the torque (force * force arm). Torsional stiffness: When an object is subjected to a torsional force, it will actually produce a torsional deformation on its circumference. The nature of the deformation is characterized by the torsional stiffness of the nature reserve, and the large torsional stiffness means that the deformation is small, and vice versa. A small torsional stiffness indicates a large amount of deformation.
