梅花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。

　　Compared with other couplings, plum-shaped elastic couplings have the following characteristics:

　　(1) Stable and reliable work, with good vibration damping, buffering and electrical insulation properties.

　　(2) The structure is simple, the radial dimension is small, the weight is light, and the moment of inertia is small, which is suitable for medium and high speed occasions.

　　Structural characteristics of plum 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. It has large axial, radial and angular compensation capabilities.

　　4. High-strength polyurethane elastic elements are wear-resistant and oil-resistant, have large carrying capacity, long service life, and reliability.

　　5. The coupling does not need lubrication, the maintenance workload is small, and it can run continuously for a long time.

　　6. The fixing methods include top wire, clamping and keyway fixing.
