MLZ type single flange plum blossom elastic coupling

MLZ type single flange plum blossom elasticCouplingIt 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.

  MLZ typeSingle flange plum blossom elasticCouplingIt 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.

  MLZ type single flange typePlum blossomFlexible couplingA whole plum-shaped elastic ring is installed between the protruding 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.This MLZ type single-flange plum blossom elastic coupling has been standardized. There are five structural forms formulated by GB/T5272-2002: LM type (basic type), LMD type (single flange type), LMS type (double flange type) Type), LMZ-I type (split brake wheel type) and LNZ-II (full brake wheel type).There are 14 specifications for each type. The applicable shaft hole diameter d=12-160mm, the shaft hole length L=35-135mm, the nominal torque T=25-25000N.m, and the allowable speed [n]=1500- 15300r.min.
