LMD (formerly MLZ) type single flange plum blossom elastic coupling
Summary:The LMD (formerly MLZ) single-flange plum blossom elastic 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 will undergo corresponding elastic deformation. , Plays the role of automatic compensation.
The LMD (formerly MLZ) single-flange plum blossom elastic 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 will undergo corresponding elastic deformation. , Plays the role of automatic compensation.
The quincunx-shaped coupling is to install an integral quincunx-shaped elastic ring between the claws of two half-couplings of the same shape to realize the connection of the two half-couplings.The power is transmitted through the squeezing between the claw and the elastic ring, and the relative deviation of the two shafts is compensated by the elastic deformation of the elastic ring to realize vibration damping and buffering.Plum blossom flexible couplings are mainly suitable for working occasions with frequent starting, forward and reverse rotation, medium and high speed, medium torque and high reliability, such as metallurgy, mining, petroleum, chemical industry, lifting, transportation, light industry, textiles, water pumps, Fan etc.
The main features of LMD (formerly MLZ) type single flange plum blossom elastic coupling:
Stable and reliable work, with 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.
It has large axial, radial and angular compensation capabilities.
The coupling does not need to be lubricated, the maintenance workload is small, and it can run continuously for a long time.
High-strength polyurethane elastic elements are wear-resistant and oil-resistant, have large carrying capacity, long service life, and are safe and reliable.
