The plum blossom coupling is a widely used coupling, also known as the claw coupling, which is composed of two metal claw discs and an elastic body.
The quincunx-shaped elastic coupling uses the quincunx-shaped elastic element to be placed between the two
half-coupling claws to realize the connection of the two half-couplings. It has the characteristics of compensating the relative displacement of the two shafts, vibration reduction, buffering, small radial size, simple structure, no need for lubrication, high bearing capacity, and convenient maintenance. However, the two halves of the coupling need to move axially when replacing the elastic element. The plum blossom coupling has a simple structure, no lubrication, easy maintenance, easy inspection, maintenance-free, and can run continuously for a long time. The high-strength polyurethane elastic element is wear-resistant and oil-resistant, has a large bearing capacity, a long service life, and is safe and reliable. The work is stable and reliable, and has good performance of vibration reduction, buffering and electrical insulation. It has large axial, radial and angular compensation capabilities. Simple structure, small radial size, light weight, small moment of inertia, suitable for medium and high speed occasions.
Structural features:
1. Intermediate elastic connection
2. Can absorb vibration, compensate radial, angular and axial deviation
3. Oil resistance and electrical insulation
4. The characteristics of clockwise and counterclockwise rotation are exactly the same
5. Set screw to fix
