Plum-shaped elastic couplings are mainly suitable for frequent starting, forward and reverse rotation, medium and high speed, medium torque and high reliability work occasions, such as: metallurgy, mining, petroleum, chemical, lifting, transportation, light industry, textile, Water pumps, fans, etc.Working environment temperature -35℃～+80℃, transmission nominal torque 25～12500Nm, allowable speed 1500～15300r/min. The ML series plum-shaped 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, which plays a role of automatic compensation.

The rated load of the Z13 expansion coupling sleeve when several expansion sleeves are used for one connection. When the rated load of the Z13 expansion coupling sleeve is less than the load to be transmitted, two or more expansion sleeves can be used in series. The total rated load is: Mtn=m.Mt where: Mtn--- total rated load of n expansion sleeves; m---load factor

JSB type serpentine spring coupling is a kind of metal elastic coupling with advanced structure.
