Importance of heat treatment of couplings

Coupling heat treatment includes material pretreatment, quenching and tempering treatment after rough turning, high frequency quenching treatment after semi-finishing and overall nitriding treatment after finishing and so on.These are the keys to improving the overall performance of the coupling.Coupling materials are divided into many types, such as cast iron, round steel, forgings, cast steel, etc., and each material is divided into many types, for example, cast iron: unbranded cast iron, HT150, HT200, HT250, etc., round steel There are many categories, such as ordinary carbon structural steel (A3), carbon structural steel (45#), alloy structural steel 42CRMO, etc. There are also many types of corresponding forgings and steel castings.The grades of these materials are different, and the corresponding mechanical properties are different. However, in order to achieve the optimization of material strength and fatigue strength, it is necessary to follow up the heat treatment of various materials, such as the tempering treatment of cast iron and cast steel materials. The internal structure of the material can improve the overall performance of the material.Coupling is an important link in transmission equipment that affects the stability of the transmission system, the service life of the equipment and the cost of use. For example, the quenching and tempering of the drum gear coupling + high-frequency treatment of the tooth surface can improve the overall performance of the coupling. At the same time, the tooth surface meshing strength of the coupling is improved. Similarly, if the manufactured elastic coupling is quenched and tempered, the overall performance of the elastic coupling will be improved.
