      Plum coupling

      TIME:2017-08-21    AUTHOR:admin




      Product introduction:
      The plum - flower coupling is a universal coupling, also called claw coupling, consisting of two metal clawed disks and a elastomer. The two metal clawed plates are generally 45 steel, but can also be used in case of high load sensitivity.
      Production process:
      The main couplings are processed by turning, milling, and pulling, and are processed by the whole heat treatment. In order to ensure sufficient mechanical strength, there is also a type of claw disc in the market, which can be produced in large quantities and removed from processing loss. Therefore, the price is much lower than machine processing. But the performance of the castings is not very good. In some important situations it is best not to use it. And the teeth of the castings are prone to tooth loss (claw tooth loss) in high speed or high load.
      (1) compact, toothless, providing three different hardness elastomers;
      (2) can absorb vibration, compensate radial and angular deviation;
      (3) simple structure, convenient maintenance and convenient inspection;
      (4) is a maintenance free, oil resistance and electrical insulation, the working temperature of 20 ℃ to 60 ℃;
      (5) the plum elastomer has four, six, eight and ten petals;
      (6) the fixed way has the top wire, clamping, the key groove fixed.
      Product features:
      Elastomers are generally made of engineering plastics or rubber. The life of the coupling is the life of the elastomer. Because the elastomer is compressed, it is not easy to be pulled. Generally, the life of elastomers is 10 years. As the elastomer has a buffer and vibration damping effect, it is used more in the case of strong vibration. The performance limit temperature of elastomers determines the use temperature of the coupling, generally -35 to + 80 degrees.
