The role and advantages of plum-shaped coupling

　　The quincunx coupling is a mechanical component that is mainly used to connect two rotating shafts in mechanical transmission, so as to transmit torque or rotation angle; it can also be used for equipment protection of the device; the shaft and the shaft cannot be separated during the movement. It can only be separated when the equipment is stopped.The quincunx coupling uses polyurethane plastic as the elastic element and the two-half coupling body is tightly combined, and the main body is made of imported aluminum alloy.The intermediate polyurethane plastic element is formulated with a unique formula, which has high wear resistance, good temperature resistance, strong toughness, and stable and durable quality with ordinary plastic parts.The quincunx body has 2 petals and 6 petals, and the fixing method has a keyway.
　　Advantages of plum blossom coupling
　　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.
　　The quincunx elastic coupling is mainly suitable for working occasions with frequent starting, forward and reverse rotation, medium and high speed, medium torque and high reliability; compared with other couplings, the quincunx coupling has the following advantages.
　　(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.
　　(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.
　　Plum-shaped couplings are widely used in metallurgy, mining, petroleum, chemical, lifting, transportation, light industry, textile, water pumps, fans and other workplaces.
