In the process of choosing the snake spring coupling, it is necessary to carry out a comprehensive study of the above factors according to the nature of each customer's own manufacturers and requirements, from now the standard coupling transmission parts to select their own needs of the coupling type, type and specification. Under normal conditions, the existing standard coupling can basically meet the needs of different working conditions.

Mechanical manufacturers in the design or selection of the transmission torque and activity of the snake spring coupling process, should be carried out torsional vibration analysis and calculation, the goal is to strike the natural frequency of the shafting, to the power of the critical speed of each order, so as to calculate the additional load and stress of the shafting and transmission device caused by torsional vibration. Because the driving torque of the power machine and the load moment of the working machine are unstable, and the dynamic load caused by the charging and the uneven centrifugal inertia force of the parts caused by the manufacturing deviation of the transmission parts, the mechanical vibration of the transmission shafting occurs under the variable load (periodic variable load and non-periodic charge load), which will affect the service life and function of the machinery. Destroy the normal working conditions of instruments and instruments, and form additional dynamic stress on shafting parts. When the total stress or alternating stress separation is greater than the promised limit, it will cause damage or fatigue damage to parts.

In the process of the need for snake spring coupling need to choose the countermeasures of damping and buffering, in fact, the basic principle is to correctly match the quality of the system, stiffness, damping and the size and frequency of the disturbance force, so that the transmission device is not in the resonance zone of the speed line operation, or in the running speed of the inner line does not appear intense resonance phenomenon.
