Composition and characteristics of plum-shaped elastic coupling

Publisher: Ever-Power Mechanical Equipment

  Quincunx elasticCouplingIt is composed of two half-couplings with the same shape of the protruding claws and elastic elements. The plum blossom-shaped elastic element is placed between the two half-coupling protruding claws to realize the coupling of the two halves of the coupling.Compared with other couplings, quincunx-shapedFlexible couplingIt has the following characteristics: stable and reliable work, with good vibration damping, buffering and electrical edge performance.The structure is simple, the radial dimension is small, the weight is light, and the moment of inertia is small. It is suitable for medium and high speed occasions.It has large axial, radial and angular compensation capabilities.The high-strength polyurethane elastic element is wear-resistant and oil-resistant, has large carrying capacity, long service life, and reliability.The coupling does not need to be lubricated, the maintenance workload is small, and it can run continuously for a long time.
  QuincunxFlexible couplingIt is mainly composed of two convex 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.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℃, transfer nominal torque 25~12500Nm, allowable speed 1500~15300r/min.
  The quincunx elastic coupling is a commonly used coupling, also called a claw coupling, which is composed of two metal claw discs and an elastic body.The two metal claws are generally made of No. 45 steel, but aluminum alloys are also useful when load sensitivity is required.Plum couplingThe elastic element is similar to a plum blossom shape, and the replacement of the elastic element requires axial movement (except for LMD and LMS models).There are two types of quincunx elastic elements: polyurethane and cast nylon.There are mainly four petals, six petals, eight petals, ten petals, and twelve petals. MT1: four petals, MT2-MT7 six petals, MT8-MT9: eight petals, MT10-MT12: ten petals, MT13-MT14: twelve petals.The main structural forms of plum coupling are: basic type, single flange type, double flange type, split brake wheel type, and integral brake wheel type.
