High-speed diaphragm couplingSeveral groups of diaphragms (stainless steel thin plates) are alternately connected with the two halves of the coupling with bolts. Each group of diaphragms is composed of several stacked ones. The diaphragms are divided into connecting rod type and different shape of the whole piece type.
The high-speed diaphragm coupling relies on the elastic deformation of the diaphragm to compensate for the relative displacement of the two shafts connected. It is a high-performance flexible coupling with strong metal components. It does not require lubrication, has a compact structure, and has a long service life. There is no rotation gap, and it is not affected by temperature and oil pollution. It has the characteristics of acid and alkali resistance. It is suitable for high temperature, high speed, and corrosive medium conditions.
high speedDiaphragm couplingThe diaphragm is fastened to the shaft sleeve with a pin and generally does not loosen or cause backlash between the diaphragm and the shaft sleeve.Some manufacturers provide two diaphragms, and some provide three diaphragms, with one or two rigid elements in the middle, and the two sides are connected to the shaft sleeve.The difference between the single diaphragm coupling and the double diaphragm coupling is the ability to handle various deviations. In view of the complex bending of the diaphragm, the single diaphragm coupling is not suitable for eccentricity.The double diaphragm coupling can bend in different directions at the same time to compensate for eccentricity.
The diaphragm coupling can compensate for the axial, radial and angular deviations between the active machine and the driven machine due to manufacturing errors, installation errors, load-bearing deformations and the effects of temperature rise changes.The diaphragm coupling is a flexible coupling with a metal elastic element. It relies on the metal coupling diaphragm to connect the main and driven machines to transmit torque. It has the advantages of elastic vibration damping, no noise, and no need for lubrication. Ideal product for type coupling and general coupling.
The structure of high-speed diaphragm coupling:
Make the left and right centers of gravity close to the support bearings of the units on both sides to the greatest extent, and the additional bending moment to the rotor shaft head is small, which is conducive to high-speed and stable operation.Intermediate joint spigot connection, integral assembly and disassembly, the entire coupling maintains centering and dynamic balance even if it is assembled and disassembled many times.The distance between the two flexible bodies (diaphragm) is large, and the coupling absorbs the misalignment of the unit.
Features of high-speed diaphragm coupling:
High-speed diaphragmCouplingThe components are made of AIS4140 or equivalent lightweight alloy. Therefore, the coupling has outstanding characteristics such as light weight, excellent axial rigidity, torsional strength and other mechanical properties, which can protect the output shaft of the unit and prolong the service life of the unit.
