How to judge the quality of the coupling?

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, some couplings also have the function of buffering, damping and improving the dynamic performance of the shafting. Generally, the power is connected with the working machine by means of a coupling. Therefore, sometimes in the process of installing the coupling, we must pay attention to the deviation in the process of connecting the shaft to the shaft.

The quality of the coupling refers to the degree of performance of the coupling in the national standard strength index, and the inferior coupling should have a similar appearance and low strength performance. Regardless of whether it is a rigid or elastic coupling, there are clear national standards that specify structural shape and strength performance indicators.

However, there are many coupling manufacturers across the country, and the shape and structure of the coupling of each coupling manufacturer are basically the same (of course, there are differences in careful observation, such as the strength level and the number of diameters of the connecting bolts, etc.), and the strength performance indicators are It is the ultimate index to measure the quality of the coupling. However, this index is often the result of the coupling users comparing the failure modes of the coupling when the transmission equipment reciprocates and starts and stops or there is a little overload.
