Comprehensive understanding of the pump drive components – couplings

The coupling, a universal component of machinery, plays a vital role in machine transmission. It connects the different mechanisms and enables the master and slave shafts to rotate in unison, thus transmitting torque efficiently. In high-speed, heavy-duty power transmission scenarios, couplings play an active role in cushioning, damping and enhancing the dynamic performance of the shaft system. Couplings are usually composed of two parts, which are connected to the main shaft and the driven shaft respectively, and are indispensable connecting parts between the power machine and the working machine.

In the face of a wide variety of coupling products on the market with different performance, how to make a reasonable choice according to the needs of the machine has always been a challenge for designers. Common types of couplings include diaphragm couplings, tooth couplings, plum blossom couplings, slider couplings, drum tooth couplings, universal couplings, safety couplings, flexible couplings, and serpentine spring couplings.
