Use and composition of diaphragm coupling
Diaphragm couplings are suitable for power transmission in high-speed, high-power, high-temperature and corrosive environments. It can replace gear couplings to achieve significant economic benefits.Main applications: steel rolling machinery, blowers, water pumps, steam turbines, air compressors, ships and aviation power plants, mining machinery, transportation machinery and petrochemical machinery, etc.Especially suitable for high-speed and high-power fans and pumps.
The diaphragm coupling is a flexible coupling consisting of a thin, high-strength stainless steel sheet metal flexible laminated group as a torsion element. The diaphragm group is interlaced with the main and driven shafts by bolts. The coupling halves are connected.Diaphragm is divided into monolithic type and connecting rod type.The diaphragm coupling relies on the elastic deformation of the diaphragm to determine the relative displacement of the two shafts connected. It is a flexible coupling with a metal elastic element with excellent performance.Because it does not require lubrication, is wear-free, and is especially suitable for high-speed and high-power applications, I am gradually replacing gear couplings as the main transmission components in the industry.
Working machine prime mover
Class I: Machinery with very small torque, such as generators, small fans, small centrifugal pumps, etc.
Class Ⅱ: Machinery with small torque changes, such as turbo compressors, blowers, woodworking machine tools, conveyors, hoists, cranes, etc.
Class III: Machinery with medium torque changes, such as mixers, compressors with flywheels, punching machines, etc.
Category IV: Machinery with medium torque changes and impact loads, such as rolling mills, ball mills, cement mixers, locomotives and ship power plants.
Features and uses:
Compared with other couplings, JMJ diaphragm coupling has the following characteristics:
Strong compensation ability. The flexible components that transmit torque are fastened on the flanges at both ends without gaps. The deformation of the flexible components compensates for the errors in the axial, radial and angular directions of the two connected shafts. The compensation ability is strong. And the axial reaction force is small.
Long life without wear It has no mutual friction between parts such as gear couplings, so it has no wear and does not need lubrication and sealing, so it has a very long life and does not require maintenance.
The structure is simple and reliable, and it is convenient to disassemble and assemble.
The transmission power is large and the speed is high.It can transmit tens of thousands of kw, and the applicable speed range is wide, up to tens of thousands of revolutions per minute.
The torsional rigidity is large, which can realize the transmission of high-precision movement.
It can work in high temperature and corrosive environment.
