Product features of plum-shaped elastic coupling
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. Use high-strength polyurethane elastic elements that are wear-resistant and oil-resistant, have large carrying capacity, long service life, and reliability;
4. It has large axial, radial and angular compensation capabilities;
5. The coupling does not need lubrication, the maintenance workload is small, and it can run continuously for a long time.

梅花形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。
ML series quincunx elastic coupling is mainly composed of two protruding 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 and plays a role of automatic compensation.
