Plum couplingIt is suitable for servo system, spindle drive, lifting platform, machine tool drive, gear box motor.Compact, no backlash, providing three different hardness elastomers, which can absorb vibration and compensate for radial and angular deviations.It is mainly suitable for working occasions with frequent starting, forward and reverse rotation, medium and high speed, medium torque and high reliability, such as: metallurgy, mining, petroleum, chemical industry, lifting, transportation, light industry, textile, water pump, fan, etc.Working environment temperature -20℃～+60℃, transmission nominal torque 25～12500Nm, allowable speed 1500～15300r/min.The quincunx-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.
