Coupling in various host products, surrounding environment is more complex, such as temperature, humidity, water, steam, dust, sand, oil, acid, alkali, corrosion medium, salt water, radiation and other conditions, is to choose one of the important factors that must be considered when the coupling. For high temperature, low temperature, oil, acid, alkali medium quality of work, unfavorable choose general rubber as the elastic element materials of flexible coupling, should choose metal elastic element flexible coupling, diaphragm coupling, for example, snake-like spring coupling, etc.

The transmission accuracy

The torque and the transmission of the shaft system, which is mainly used to transfer motion, require the coupling to have higher transmission accuracy, and the flexible coupling of non-metallic elastic elements should be used. Large shaft transmission of torque and transmission power, there is no requirement for the transmission accuracy, high speed, should avoid to choose metal elastic element elastic coupling and clearance between moving components of flexible coupling, diaphragm coupling of appropriate chooses high driving accuracy.
