Clamping type spline plum blossom elastic coupling

Plum ElasticityCouplingIt is composed of two half couplings with the same shape of the protruding claws and elastic elements, using plum blossomsFlexible couplingThe element is placed between the two halves of the coupling claws to realize the connection of the two half quincunx couplings.The quincunx elastic coupling has the characteristics of compensating for the relative deviation of the two shafts, damping, buffering, small radial size, simple structure, no lubrication, high carrying capacity, convenient maintenance, etc.

      Plum ElasticityCouplingIt is composed of two half couplings with the same shape of the protruding claws and elastic elements, using plum blossomsFlexible couplingThe element is placed between the two halves of the coupling claws to realize the connection of the two half quincunx couplings.It has the characteristics of compensating for the relative deviation of the two shafts, damping, buffering, small radial size, simple structure, no lubrication, high carrying capacity, convenient maintenance, etc. Basic typePlum couplingWhen replacing the elastic element, the two halves need to move in the axial direction. The double flange type can replace the elastic element without moving the coupling axially.It is suitable for connecting two coaxial lines, frequent starting, forward and reverse changes, medium and low speed, medium and small power transmission shaft systems, and working parts that require high working reliability. The basic plum blossom flexible coupling is not suitable for heavy loads and axial directions. The size is limited, and the two axes are difficult to align after replacing the elastic element.After the revision of the standard, the materials of plum elastic coupling components are polyurethane and cast nylon.According to different working conditions, choose different materials, such as fans, water pumps, light industry, textiles, etc. When the work is stable and the load changes little, polyurethane can be selected.The prices of the two materials are relatively related.Strength calculation of plum blossom elastic coupling
The strength calculation of the quincunx coupling is mainly to check the pressure of the bearing surface when the elastic element is loaded.
 P=16TC÷Zb(D1-D2)≤〔P〕
WhereTCMeans: the calculated torque of the coupling N. mm;
Z means: the number of plum petals of the plum elastic coupling element;
B means: Axial width of quincunx coupling elementmm;
[P] means: allowable pressure of elastic element material 2N/mm2.When using rubber materials, generally take [P]=1.8-2N/mm2; When the load is stable and the speed is not high, the allowable pressure can be increased by more than 1 time; when using polyurethane material, it is possible to take [P]=2.5-3 N/mm2; When using cast nylon material,〔P〕=3.5-4N/mm2.
