Coupling drawings are generally structural drawings, which refer to the overall dimensions of the installation. For detailed processing dimensions, please refer to the relevant standards.There are many types of couplings, and there are those with national standard and non-standard ranges.Commonly used couplings include drum tooth type, elastic pin tooth type, diaphragm, star, plum blossom, tire, slider, roller chain and so on.

　　The drawings of the coupling are drawn according to the national standard data professionals, and the non-standard drawings are evolved according to the national standard data.When choosing a coupling, the designer should first choose among the couplings that have been formulated as national standards, machinery industry standards, and national patents. Only when the existing standard couplings and patented couplings cannot meet the design needs Need to design the coupling by yourself.
