Hebei LMD plum-shaped elastic coupling

The LMD plum-shaped elastic coupling is composed of two claw-shaped couplings and a plum-shaped elastic cushion. The plum blossom cushion is placed between the two claw-shaped couplings to realize the connection of the two halves of the coupling.

The middle elastic body of the LMD quincunx elastic coupling closely meshes with the claws of the two half-couplings and bears radial and circumferential extrusion to transmit torque. When the two axes are displaced relative to each other, the middle elastic body undergoes corresponding elastic deformation , Plays a role in automatically compensating for displacement.

LMD plum-shaped elastic coupling is mainly suitable for medium load, frequent starting, frequent forward and reverse rotation, high, medium and low, working occasions, and not suitable for heavy loads.For example: metallurgy, mining, petroleum, chemical industry, lifting, transportation, light industry, textile, water pump, fan, etc.The working temperature is -35℃～+80℃, the torque range is 45～25000, and the speed range is 1500～8500r/min.

LMD plum blossom elastic coupling features: simple structure, small radial size, light weight, small moment of inertia, used in medium and high speed applications,Plum couplingIt works stably and has good damping, buffering and electrical insulation properties.

1. 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.

2. 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 applied. It can reduce the natural vibration frequency of the shaft system and change the torsional vibration characteristics of the diesel engine power unit shaft system. 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, and prolong the service life of the gear.
