What are the characteristics of DJM expansion sleeve diaphragm coupling?

DJM expansion sleeve diaphragm coupling is a coupling that uses plum blossom elastic elements to be placed between the two halves of the coupling claws to realize the elastic connection of the two halves of the coupling.

特点

1. It has high elasticity (low stiffness, high flexibility), the rotation angle is 10 degrees when bearing the nominal torque, and 25 degrees when the torque is large, which can reduce the natural vibration frequency of the shaft system and change the torsional vibration of the diesel engine power unit shaft system. Characteristics, so that the diesel engine does not appear dangerous resonance speed within the required speed range.

2. It has good damping and vibration reduction characteristics, which can absorb part of the vibration energy, reduce the vibration amplitude when passing through the vibration point, and reduce the torsional vibration stress of the shaft section.

3. It has high elasticity (low stiffness, high flexibility), the rotation angle is 10 degrees when bearing the nominal torque, and 25 degrees when the torque is large, which can reduce the natural vibration frequency of the shaft system and change the torsional vibration of the diesel engine power unit shaft system. Features, so that the diesel engine does not appear dangerous resonance speed within the required speed range. It can absorb and reduce the fluctuation of the output torque of the diesel engine. For the diesel engine power unit equipped with a reduction gear box, it can reduce the impact on the gear surface when the torque is changed. Knock to extend the service life of gears.
