     DiaphragmCouplingThe elastic element is a thick metal reed, often made into a washer (diaphragm), with 4-8 bolt holes on its circumference, which are connected to the two halves of the coupling with bolts staggered, usually several diaphragms are stacked on Torque is transmitted together, and the relative displacement of the connected two shafts is compensated by the elastic deformation of the diaphragm.This kind of coupling has simple structure, convenient disassembly and assembly, reliable operation, no relative sliding, no lubrication and no noise.butDiaphragm couplingThe diaphragm has low elasticity and poor cushioning and vibration absorption capabilities, and can be used for high-speed transmission with relatively stable loads.
     The allowable angular displacement of the diaphragm coupling is 0.5"; the radial displacement is related to the intermediate length, the intermediate shaft length is 100mm, the angular displacement is 0.5", and the radial displacement is 1mm. Generally, the intermediate shaft length should not exceed the outer diameter of the coupling It is suitable, because the thickness of the diaphragm is very thin, generally 0.25-0.50mm, the elastic deformation of the diaphragm can allow a small amount of relative axial displacement of the two axes (<2.5mm).
     The structure of the diaphragm of the diaphragm coupling:
In order to improve the torsional elasticity of the diaphragm, the diaphragm coupling diaphragm can be made into a structure with two rings of evenly distributed bolt holes, and a shaped hole is made between the two rings of screw holes to increase the elasticity of the diaphragm.This kind of diaphragm has a larger outer diameter and higher rigidity. The web part between the two rings of screw holes also bears torsion, so the load-bearing capacity is higher. The evenly distributed bolt holes on the annular diaphragm are arranged staggered.When the torsion is transmitted, one side stretches and the other side compresses, and the load-bearing part is mainly the stretched side.In order to increase the tensile elasticity of the diaphragm, the outer edge is processed into an arc to become a polygon, but the line of force (the connection between the two bolt holes) should not exceed the range of the side width to prevent the diaphragm from being loaded. Bending reduces the strength. The structure with fewer sides under the same outer diameter will increase the side length due to the decrease in the number of sides, and the elasticity is better. The relative displacement of the two shafts connected to the compensation can be larger, but due to the number of sides participating in the load transfer Decrease, its carrying capacity is reduced, and the driven shaft speed fluctuates.
