The torque transmission of the coupling is mainly to set the nominal torque requirement of the transmission system. When overloading, the torque transmission element is separated from the two halves of the coupling to realize the protection of the transmission system at both ends of the main shaft.

　　High-quality couplings should match the strength of the two halves of the coupling with the overall strength of the transmission system, and the strength of the coupling accessories is the nominal torque requirement of the coupling, that is, the failure mode of the coupling should be the coupling accessories Damaged and the two halves of the coupling are basically intact, such a coupling is a coupling.

　　Coupling materials are roughly divided into sections (round steel), castings (cast iron or cast steel), forgings, etc., and cast steel and forgings are most of the choices of coupling materials.Profiles are generally the coupling materials that are often used in relatively small couplings. For example, plum blossom couplings below ML5 (outer diameter is 125). However, when such small couplings are manufactured using profiles, Note that quenching and tempering is the key to effectively improving material performance. The choice of coupling material is directly related to the performance of the coupling.
