　　Vibration is the main reason for the damage of the cam and groove coupling. In the design of the driving system of machine and selection of motor, cam and groove coupling must be considered when the condition coefficient K VI mechanical vibration is about 2.3 times of the I class, which is the torque changes and have a strong impact loading machinery must choose a larger factor of safety in the design selection. Although the safety coefficient is large, single impact load is still inevitable, often because of the torque changes and the impact load is strong and the premature failure.

　　After the application of fluid cam and groove coupling, cam and groove coupling separates the motor and working machine, motor load is directly coupling pump wheel, there is no direct contact with the work machine, thus avoiding the mutual transmission of vibration and superposition. In addition, hydraulic cam and groove coupling of liquid, and liquid has the function of vibration reduction, so after the application of hydraulic cam and groove coupling transmission, can reduce the impact and isolation of torsional vibration effectively. Select motor and coupling coefficient, conditions may be appropriate to reduce. For example, plants with single roll crusher, impact load is very strong.

　　Before not using hydraulic cam and groove coupling to transmit, and used for less than 3 months, the motor bearing was damaged, motor stator and rotor burnt. After using the hydraulic cam and groove coupling transmission, separated from the strong vibration machine, the motor will not damage. Another example of air spinning machine of spinning, speed up to 20000r/min, any vibration does not allow, application of hydraulic cam and groove coupling transmission, stable starting, no vibration and spaced from the vibration of a motor, the rotor can work smoothly.
