The choice of coupling is very important, choose the right coupling, can improve its work efficiency, so we know the choice of the main basis of coupling what?

The type of engine is the basic factor for selecting the type of coupling:

The power of the engine is one of the main bases to determine the size of the coupling, and the coupling torque is proportional. Between the power machine to work through one or several different varieties or different types, specifications of the coupling will be the main, driven end up, the formation of shafting transmission system.

Select the best coupling suitable for the system:

In mechanical transmission, power engines are nothing more than electric motors, internal combustion engines and steam turbines. Because of the different working principle and structure of the power machine, its mechanical characteristics are very different, some running smoothly, some running impact, the formation of unequal impact on the transmission system. According to the mechanical characteristics of the engine, the corresponding engine coefficient KW should be selected, and the best coupling suitable for the system should be selected.

Load type of transmission system:

The load category of the transmission system is the basic basis for selecting the type of coupling. Impact, vibration and torque change larger load, should choose flexible coupling with elastic components namely elastic coupling, in order to buffer, vibration reduction, compensation axis offset, improve the transmission system performance. Start frequently, positive and negative rotation, braking torque is normal balanced working torque several times, is overloaded work, will shorten the service life of coupling elastic components, coupling is only allowed to short overload, generally short time load shall not exceed the nominal torque of 2~3 times, that is [Tmax]≥2~3Tn.
