There are various important mechanical parts in the power transmission such as the speed reducers, sprockets, worms, and gears, etc. Among them, couplings play a very important part in the power transmission also.
Couplings have various species, varieties, and sizes. As a result, in order to choose appropriate products, customers should take many aspects into consideration. In addition to the correct understanding of the species, varieties, sizes, they ought to pick the couplings according to the desires of the transmission system. First of all, they can choose from couplings that have been made as a standard. At present, there are various kinds of standard couplings in China. Most of them are universal couplings. Each coupling has its own characteristics and programs. Basically, they are able to meet the requirements of a variety of conditions.
Among so many standard couplings, the good choice of products is related with the performance, reliability, service life, vibration, noise, energy, transmission efficiency, transmission accuracy, economy and other issues of the machinery shaft. Besides, additionally it is related to the quality of the product. The following are some aspects which should be considered when choosing the right products.
The first one is the mechanical properties of the charged power machine. In the mechanical transmission, the charged strength machines may refer to motor, internal combustion engine and the turbine. Due to the different operating principle and the structure of the charged power machines, their mechanical properties vary greatly. Some run easily, while some may have impact on the transmission system. The type of power device is the basic factor to select coupling species. The energy is one of main basis that can determine the specifications of the coupling. Besides, the energy is definitely proportional to the torque of the coupling.
The second one is the type of loads. Because structures and materials are different, the carrying capacity of couplings that used in various transmission systems of the mechanical products also vary greatly. Different types of loads are resulted from the impact on work loads mainly, vibration, rotating, and braking, etc. Load categories of the traditional system are the schedule for the selection of coupling species.

The third one is the allowable speed. Different specifications and species of the coupling may lead to the different ranges of allowable speed. The change of coupling materials can increase the allowable speed range. For example, allowable speed of steel material is greater than that of cast iron materials.
Addition to the above aspects, there are various others such as the transmission accuracy still, the sizes of coupling, installation, maintenance, and working circumstances, etc. All of them are quite important for the choice of couplings.
