There are several important mechanical parts in the power transmission such as the speed reducers, sprockets, worms, and gears, etc. Among them, couplings also play a very important part in the power transmission.
Couplings have various species, types, and sizes. Therefore, in order to choose appropriate products, customers should take many aspects into consideration. In addition to the correct understanding of the species, types, sizes, they should choose the couplings according to the requires of the transmission system. First of all, they can choose from couplings that have been formulated as a standard. At present, there are several kinds of standard couplings in China. Most of them are universal couplings. Each coupling has its own characteristics and applications. Basically, they can meet the needs 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, it is also 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 power machine. In the mechanical transmission, the power machines may refer to motor, internal combustion engine and the turbine. Due to the different operating principle and the structure of the power machines, their mechanical properties vary greatly. Some run smoothly, while some may have impact on the transmission system. The type of power machine is the basic factor to select coupling species. The power is one of main basis that can determine the specifications of the coupling. Besides, the energy is proportional to the torque of the coupling. Cardan Shaft Manufacturers
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 mainly resulted from the impact on work loads, vibration, rotating, and braking, etc. Load categories of the traditional system are the basis for the selection of coupling species.
The third one is the allowable speed. Different species and specifications of the coupling may lead to the different ranges of allowable speed. The noticeable 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 several others such as the transmission accuracy still, the sizes of coupling, installation, maintenance, and working conditions, etc. All of them are quite important for the choice of couplings.
