The scope of application and performance characteristics of the LMZ-I split brake wheel plum elastic coupling.
1. The LMZ-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 will have corresponding elasticity. Deformation plays a role of automatic compensation.
2、梅花弹性联轴器主要适用于起动频繁、正反转、中高速、中等扭矩和要求高可靠性的工作场合，例如：冶金、矿山、石油、化工、起重、运输、轻工、纺织、 水泵、风机等。工作环境温度 -35℃～+80℃，传递公称扭矩25～12500Nm，许用转速1500～15300r/min。
3. Compared with other couplings, plum elastic couplings have the following characteristics:
(1) Stable and reliable work, with good vibration damping, buffering and electrical insulation properties.
(2) It has large axial, radial and angular compensation capabilities.
(3) High-strength polyurethane elastic elements are wear-resistant and oil-resistant, have large carrying capacity, long service life, and reliability.
(4) Simple structure, small radial size, light weight, small moment of inertia, suitable for medium and high speed occasions.
(5) The coupling does not need to be lubricated, the maintenance workload is small, and it can run continuously for a long time.
