Coupling is a mechanical part used to connect two shafts (active shaft and driven shaft) in different mechanisms to rotate together to transmit torque.In high-speed and heavy-duty power transmission
As for lubricating oil, viscosity is its main performance index. Viscosity reflects the internal friction of oil, and is an indicator of oil properties and fluidity.Without adding any functional additives, the higher the viscosity, the higher the oil film strength and the worse the fluidity.
The diaphragm coupling is composed of several groups of diaphragms (stainless steel thin plate) which are alternately connected with the two halves of the coupling with bolts. Each group of diaphragms is made up of several pieces. The diaphragms are divided into rod type and different shapes. The whole piece.
Flexible coupling without elastic elements: large load-bearing capacity, but also does not have cushioning and shock absorption performance, and there will be impact noise at high speed or unstable rotation or frequent forward and reverse rotation.It is suitable for occasions with low speed, heavy load and stable speed.
The clamp shell coupling and the flange coupling are both rigid couplings and have a wide range of applications. It uses two clamp shells split along the axial direction and tightened in a certain way to achieve the coupling of the two shafts. Shaft.
The coupling is an important part connecting the prime mover and the working machine. Its damage will cause the machine to stop and even spread to the entire operation line. Therefore, its reliability is very high.However, the conditions under which cross-shaft universal joints are located often have certain limitations.

The response process of the elastic coupling is faster when it is overloaded, and the disconnection of the elastic coupling or the separation of the power input end and the output is also faster.This type of elastic coupling is known for its good disengagement performance and relatively small red area in the performance curve.
