LMZ-I (formerly MLL-I) split brake wheel plum-shaped elastic coupling

LMZ-I (MLL-I) split brake wheel plum blossom elastic coupling is mainly composed of two convex teeth closely meshed and subjected to radial compression to transmit torque. When the two axes are relatively offset, the elastic element Corresponding elastic deformation occurs, which plays a role of automatic compensation.

LMZ-I (formerly MLL-I) split brake wheel plum-shaped elastic coupling
　　LMZ-I (MLL-I) typeSplit brake wheel plum-shaped elastic couplingIt 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.
　　Compared with other couplings, plum-shaped elastic couplings have the following characteristics:
　(1) Stable and reliable work, with good vibration damping, buffering and electrical insulation properties.
　(2) Simple structure, small radial size, light weight, small moment of inertia, suitable for medium and high speed occasions.
　(3) It has large axial, radial and angular compensation capabilities.
　(4) High-strength polyurethane elastic elements are wear-resistant and oil-resistant, have large carrying capacity, long service life, and reliability.
　(5) The coupling does not need to be lubricated, the maintenance workload is small, and it can run continuously for a long time.
