The coupling is a simple transmission spare part. Because the coupling has a simple structure, easy disassembly and assembly, and simple texture, it has been favored by the public in recent years. The development of the coupling is getting better and better, and the metal diaphragm coupling is a kind of coupling.
The metal diaphragm coupling is one of the flexible couplings with metal elastic elements. The metal diaphragm coupling consists of a single piece or several diaphragms stacked together to transmit movement and power. The elastic element is a thin washer-shaped metal reed (diaphragm), with 4-8 bolt holes on its circumference, which are staggered to connect the two halves of the coupling with bolts. The elastic deformation of the diaphragm is used to compensate the connected two. The relative displacement of the shaft.
The metal diaphragm (disc) coupling has simple structure, light weight, convenient disassembly and assembly, reliable work, easy balance correction, and no relative sliding, so it does not need to be lubricated or noiseless, and it is convenient to maintain; but the diaphragm is torsionally flexible Small, poor cushioning and vibration absorbing ability. Therefore, it is suitable for high{{0}}speed transmission with relatively stable load and harsh working environment. The allowable angular displacement of this coupling is 0.5 degrees, the radial displacement is 1 mm, and the relative axial displacement is less than 2.5 mm.
Diaphragm couplings are widely used in the shaft transmission of different types of equipment and machinery, such as water pumps (especially high-power, chemical pumps), fans, compressors, hydraulic equipment, petroleum equipment, printing equipment, textile equipment, chemical equipment, Mining equipment, metallurgical equipment, navigation (helicopter), naval high-speed power transmission systems, steam engines, piston-type power equipment transmission systems, crawler vehicles, and new energy equipment group high-speed, high-power equipment transmission systems, after dynamic balance It is more common to be used in high-speed transmission shafting.
