Detailed parameters of LMD (formerly MLZ) type single flange plum-shaped elastic coupling
    LMD (formerly MLZ) type single flange plum blossom elastic coupling is mainly composed of two protruding teeth closely meshed and subjected to radial compression to transmit torque. When the two axes are relatively offset, the elastic element undergoes corresponding elastic deformation , Plays a role of automatic compensation.
　　The plum-shaped elastic coupling has the following characteristics: the flower-shaped elastic coupling has simple structure, small radial size, light weight, and small moment of inertia. It is suitable for medium and high-speed occasions. The plum-shaped elastic coupling is stable and reliable, and has good vibration reduction. , Buffer and electrical insulation properties.The quincunx-shaped elastic coupling has large axial, radial and angular compensation capabilities. The quincunx-shaped elastic coupling has high-strength polyurethane elastic elements that are wear-resistant and oil-resistant, have large load-bearing capacity, long service life, and are safe and reliable. No need for lubrication, low maintenance workload, and continuous long-term operation.

　　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。
