  Plum blossomCouplingThere are many reasons for the deviation, and the common ones are: 1. The coaxiality deviation of the motor and the pump is different, which is commonly known as the misconcentricity; 2. The coupling is severely worn when there is no rubber pad, and there is a little contact phenomenon; 3. Glue The quality of the mat itself is not good, the elasticity is poor, and the toughness is not enough.Plum couplingIt is processed by machining methods such as turning, milling, and broaching, and then undergoes overall heat treatment.In order to ensure sufficient mechanical strength of the two types of plum blossom couplings, there is also a claw plate on the market that is a casting, which can be mass-produced and eliminates processing losses.So the price is much lower than machining. But the performance of castings is not very good.It is better not to use it in some important occasions.And the claws of the casting are prone to tooth punching (claws falling off) at high speed or high load.
  (1)Compact, no backlash, providing three different hardness elastomers;
  (2) Vibration can be absorbed, and radial and angular deviation can be compensated;
  (3) Simple structure, convenient maintenance and inspection;
  (4) Maintenance-free, oil-resistant and electrical margin, working temperature 20℃-60℃;
  (5) Plum blossom elastomer has four petals, six petals, eight petals and ten petals;
  (6) The fixing methods include top wire, clamping and keyway fixing.
  Elastomers are generally composed of engineering plastics or rubber.The life of the coupling is also the life of the elastic.Since elasticity is under pressure, it is obviously under tension.The life of the general elastic body is 10 years. Because the elasticity has the function of buffering and damping, it is used more in the occasion of strong vibration.The performance limit temperature of the elastomer determines the use temperature of the coupling, which is generally -35 to +80 degrees.
