Optimum setting of coupling parts strength

Nominal torque is the standard setting of all kinds of rigid or elastic coupling, which is also the optimal setting of the strength of the coupling parts, and the strength of the two halves of the coupling should match the specific transmission equipment. There are many coupling manufacturers, the price competition of the coupling is fierce and obvious, and the quality competition of the coupling is often evaluated by the coupling direct user after the transmission equipment for a long time reciprocating start and stop or a little overload, feeling the coupling parts and the durability of the two halves of the coupling. The nominal torque of the coupling parts is reflected in the selection of the strength of the coupling parts at the same time, we should pay attention to the strength optimization of the two halves of the coupling, for example, the HL elastic pin coupling coupling parts are nylon pin, in the optimization of the standard material nylon rod at the same time, we should pay attention to the strength and fatigue strength of the two halves of the coupling, Common type of cast steel strength and fatigue strength is relatively low, so the two halves of the coupling is often coupling parts vulnerable at the same time, accompanied by two and a half coupling deformation of the discarded, it is need to coupling and coupling of the concern of users, the same situation also exists in other various types of rigid or flexible coupling series, such as, The two halves of the metal diaphragm coupling components elastic coupling material and heat treatment, etc., the coupling of material and heat treatment process is different, price of coupling is different at the same time, the quality of the coupling is different, the coupling ratio of benign competition should be under the coupling are of good quality price competition, which is a common concern to the industry.
