The ML type plum blossom coupling is mainly composed of two protruding 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.The nominal torque is 25~12500Nm and the allowable speed is 1500~15300r/min.
ML plum blossom coupling has the following characteristics: stable operation, good vibration damping, buffering and electrical insulation properties.The 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.Plum elastic couplingIt has large axial, radial and angular compensation capabilities. The polyurethane elastic element is oil-resistant, has a large bearing capacity, and has a long service life. The coupling does not need lubrication, and the maintenance workload is small, and it can run continuously for a long time.Plum blossom couplings are mainly suitable for working occasions with frequent starting, forward and reverse rotation, medium and high speed, medium torque and high requirements, such as: metallurgy, mining, petroleum, chemical industry, lifting, transportation, light industry, textiles, water pumps, fans Wait.
