There are many types, types and specifications of couplings. On the basis of correctly understanding the respective concepts of varieties, types and specifications, the couplings are selected according to the needs of the transmission system. Firstly, they are selected from the couplings that have been formulated as standards. There are more than a dozen national standard and standard standards. Most of these standard couplings are universal couplings. Each type of coupling has its own characteristics and scope of application, which can basically meet the needs of various working conditions. In general, the designer does not need to design the coupling by himself.
Only when the existing standard coupling can not meet the needs, the coupling needs to be designed. Standard couplings are easy to purchase and are much cheaper than self-designed non-standard couplings. Among the many standard couplings, the correct choice of the best coupling for your needs is related to the working performance, reliability, service life, vibration, noise, energy saving, transmission efficiency, transmission accuracy of the mechanical product shafting transmission. A series of issues, such as economics, are also related to the quality of mechanical products.
Designers should choose the coupling from the perspective of the shafting drive system when selecting the coupling. Avoid simply selecting the coupling from the main and driven end connections.
