MLPK type plum blossom elastic coupling with brake disc

Product Details

Plum blossom elastic coupling is a coupling that uses plum elastic elements placed between the jaws of two halves of the coupling to realize the elastic connection of the two halves of the coupling. Definition of scientific and technological terms Chinese Name: plum blossom elastic coupling English name: Coupling with elastic spider Definition: Applied discipline: mechanical engineering (first-level discipline); Mechanical parts (second-level discipline); Coupling (Level 3 discipline) Plum coupling is a whole plum blossom elastic ring between the jaws of two half couplings of the same shape to realize the connection of two half couplings. The power is transmitted by the extrusion between the jaw and the elastic ring, and the relative offset of the two axes is compensated by the elastic deformation of the elastic ring to achieve vibration-damping buffering. This coupling has been standardized, GB/T5272-2002 formulated five structural forms: LM type (basic type), LMD type (single flange type), LMS type (double flange type), LMZ-I type (split brake wheel type) and LNZ-II (integral brake wheel type). Each form has 14 specifications, they are suitable for shaft hole diameter d=12-160mm, shaft hole length L=35-135mm, nominal torque T=25-25000N.m, allowable speed [n]=1500-15300r.min.

1. It has high elasticity (low stiffness, large flexibility), the rotation angle is 10 degrees when bearing the nominal torque, and the maximum torque is 25 degrees, which can reduce the natural vibration frequency of the shafting system, change the torsional vibration characteristics of the shafting system of the diesel engine power unit so that the diesel engine does not have a dangerous resonance speed in the range of required speed

2. It has good damping and damping characteristics, which can absorb part of the vibration energy, reduce the vibration amplitude when passing through the vibration point, and reduce the torsional vibration stress of the shaft section.

3. It has high elasticity (low stiffness, large flexibility), the rotation angle is 10 degrees when bearing the nominal torque, and the maximum torque is 25 degrees, which can reduce the natural vibration frequency of the shafting system, change the torsional vibration characteristics of the shafting system of the diesel engine power unit so that the diesel engine does not have a dangerous resonance speed in the range of required speed. It can absorb and reduce the fluctuation of diesel engine output torque, and for a diesel engine power units equipped with a reduction gearbox, it can reduce the knocking on the gear surface when changing torque and prolong the service life of the gear.
