MOREGuangdong MLL plum blossom coupling
Main features of MLL plum coupling:
1. MLLPlum couplingThe structure is simple, the radial dimension is small, the weight is light, and the moment of inertia is small. It is suitable for medium and high speed occasions.
2. MLL plum coupling works stably and reliably, with good vibration damping, buffering and electrical insulation properties.
3. MLL plum coupling has greater axial, radial and angular compensation capabilities.
4. MLL plum coupling has high-strength polyurethane elastic elements, with large load-bearing capacity, long service life and reliability.
5. The coupling does not need lubrication, the maintenance workload is small, and it can run continuously for a long time.Plum blossom-shaped elastic couplings are mainly suitable for frequent starting, forward and reverse rotation, medium and high speed, medium torque and high reliability work occasions, such as: metallurgy, mining, petroleum, chemical, lifting, transportation, light industry, textile, Water pumps, fans, etc.Working environment temperature -35℃~+80℃, transmission nominal torque 16~25000Nm, allowable speed 1500~15300r/min.
The MLL plum coupling is mainly composed of two convex teeth that are closely meshed and subjected to radial compression to transmit torque. When the two axes are relatively offset, the elastic element undergoes corresponding elastic deformation, which plays a role of automatic compensation.
