It 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. 2. 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, Textiles, 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 widely 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.
The quincunx-shaped elastic coupling is composed of two half-couplings with the same shape of the claws and elastic elements. The quincunx-shaped elastic element is placed between the two halves of the coupling claws to realize the coupling of the two halves. Join.
Compared with other couplings, quincunx elastic couplings have the following characteristics: (1) Stable and reliable operation, with good vibration damping, buffering and electrical insulation properties. (2) Simple structure, small radial size, light weight, small moment of inertia, 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 are safe and reliable. (5) The coupling does not need lubrication, the maintenance workload is small, and it can run continuously for a long time.
