Clamping spline plum blossom elastic coupling

  Clamping spline plum-shaped elastic coupling:  

  The clamp-type spline plum blossom elastic coupling has the characteristics of compensating the relative deviation of the two shafts, damping, buffering, small radial size, simple structure, no lubrication, high carrying capacity, and convenient maintenance.The polyurethane elastomer is limited by the convex claw block, which can avoid internal deformation caused by impact and external deformation caused by centrifugal force; the large concave surface of the convex claw makes the surface pressure on the involute tooth very small, even if the tooth is overloaded , The teeth will not be worn or deformed. The standard spline hole polyurethane plastic is an elastic element, which has the advantages of cushioning, shock absorption, wear resistance, easy disassembly and assembly, and the working temperature is -35~+80 degrees.

  Material of plum coupling:
  Plum blossom couplings are mainly made of cast steel and 45# steel; the connection forms include keyway connection, set screw connection, clamping connection, or a combination of two forms of connection.Axial plug-in installation.If radial installation is required, it can be made into a flange type to transmit power through the extrusion between the claws and the elastic ring, and the relative deviation of the two shafts can be compensated by the elastic deformation of the elastic ring to achieve vibration reduction.There are many types to choose from, such as keyway type, clamping type, extended type, flange type and so on.Widely used in water pumps, oil pumps, machine tools and other industries.

(1) The selected material is cast steel. Under the condition of bearing the same torque, the volume of the cast steel coupling is much smaller than that of cast iron, which improves the efficiency and reduces the cost;

(2) The structure is composed of half couplings on both sides and a plum blossom cushion in the middle. The structure is very simple, so it is very easy to disassemble and assemble. Just remove any half of the coupling and the plum blossom cushion can be disassembled;

(3) The two halves of the coupling are completely connected by the elastic plum cushion in the middle, so the allowable radial displacement is 0.8-1.2mm. It is much easier to correct the coaxiality of the two shafts. Compared with the elastic sleeve, the two halves of the coupling are connected. Under the premise of bearing the same torque, the contact area with the semi-coupling has been greatly increased, which prolongs the service life of the coupling. At the same time, the plum blossom cushion in the middle can also play the role of vibration isolation and insulation.
 Performance characteristics of plum-shaped elastic coupling:

    1. High cost performance, with buffering and vibration reduction performance, angular compensation, easy to disassemble and assemble

    2. With large torque, it is an ideal product with high output power, suitable for the use of industrial and mining machinery and equipment;

    3. The inner diameter of the coupling is divided into: straight hole type (B type), tapered hole type (F, H type), which has the advantages of convenient and accurate replacement and disassembly.

    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 industry, lifting, transportation, light industry, textile, Water pumps, fans, etc.Working environment temperature -35℃～+80℃, transmission nominal torque 25～12500Nm, allowable speed 1500～15300r/min.

    Cangzhou Ever-Power Co., Ltd. mainly produces eight series of couplings with more than 1000 specifications. There are more than XNUMX series of expansion sleeves and thousands of specifications. At present, the couplings with a torque of XNUMXKNm can be produced. Non-standard products can also be designed and produced according to user requirements.Products are widely used in metallurgy, chemical, printing, fan, transportation and other mechanical fields, and are exported to the Far East and Southeast Asia.
