Composition and insulation performance of plum blossom elastic coupling

　　The quincunx elastic coupling is composed of two half-couplings with the same shape of the claws and elastic elements. The plum-shaped elastic element is placed between the claws of the two coupling halves to realize the connection of the two halves of the coupling. .Plum elastic coupling made of carbon steel.Low-carbon steel has good plasticity and low strength. After adding an appropriate amount of carbon element, it will become hard, and the plasticity will decrease and the strength will increase.Plum blossom elastic coupling connection may need to withstand high tensile, compression, torsion and shear strength. Plum blossom elastic coupling is a better choice. Generally used in transmission parts. Transportation, storage and use environment Data: shock and vibration, ambient temperature and humidity range, the presence of oils, solvents, corrosive liquids, steam, sand, dust, salt water and radiation.The expected deviation between the connected shafts: the general and large deviations allowed in the running state in the angular, radial, and axial directions, and the general and large deviations allowed during operation and parking.The effect of temperature changes.
　　The performance requirements of the coupling: torsional stiffness; axial stiffness, the critical speed requirements of the intermediate shaft coupling.
　　The plum blossom flexible coupling has good electrical insulation properties and the following characteristics:
　　(1) The plum blossom coupling has greater axial, radial and angular compensation capabilities.
　　(2) The plum blossom coupling has simple structure, small radial dimension, light weight and small moment of inertia, suitable for medium and high speed occasions.
　　(3) The plum blossom coupling works stably and reliably, with good vibration damping, buffering and electrical insulation properties.
　　(4) The plum blossom coupling does not need lubrication, the maintenance workload is small, and it can run continuously for a long time.
　　(5) The high-strength polyurethane elastic element of the plum coupling is wear-resistant and oil-resistant, has a large bearing capacity, a long service life, and is reliable.
