Plum-shaped elastic coupling has a simple structure without lubrication

  Quincunx elasticCouplingThe elastic element is similar to a plum blossom shape. The coupling has the properties of compensating the relative deviation of the two shafts, damping, and buffering. It has a small diameter, simple structure, no lubrication, high load capacity and easy maintenance. The replacement of the elastic element requires axial movement. It is suitable for Coaxial connection, frequent starting, forward and reverse changes, medium speed, medium torque and other transmission shaft systems and working parts that require high working reliability.It is not suitable for low-speed, heavy-duty and limited axial dimensions where it is difficult to align the two shafts after replacing the elastic element.QuincunxFlexible couplingIt is processed by machining methods such as turning, milling, and broaching, and then is heat-treated as a whole to ensure sufficient strength.
  Plum-shaped elastic couplingIt has good balance performance and is suitable for high-speed applications (high speed up to 30000 rpm), but it cannot handle large deviations, especially axial deviations.Larger eccentricity and deflection angle will produce a larger bearing load than other servo couplings.Another value of concern is the failure of the quincunx elastic coupling.Once the quincunx elastic spacer is damaged or fails, the torque transmission will not be interrupted, and the metal claws of the two shaft sleeves mesh together to continue to transmit the torque, which is likely to cause problems in the system.Choosing the appropriate plum blossom elastic spacer material according to the actual application is a major trend of this coupling. Different hardness and temperature tolerance allow customers to select the appropriate material to meet the performance standards of the actual application.
