Those characteristics of diaphragm coupling

Publisher: Ever-Power Mechanical Equipment


  1. High torque rigidity and high sensitivity, high torque load;

  2. Zero gyration clearance;

  3. It has oil and corrosion resistance properties;

  4. The stainless steel diaphragm absorbs vibration and compensates radial, angular and axial deviations;

  5. The clockwise and counterclockwise rotation characteristics are exactly the same;

  6. Material: aluminum alloy;

  7. The keyway can be processed according to customer needs.Metric or imperial size aperture.Integrated design, often used in machine tool platform, stepping servo system, screw spindle drive.

  Diaphragm couplingIt can actively compensate the axial, radial and angular offset caused by the motor, as well as the influence caused by factors such as manufacturing error, installation error, bearing deformation and temperature rise.Diaphragm coupling is a metal elastic element in flexible coupling. The driven motor transmits torque, elastic vibration, noise-free, and non-lubricated point. It is an ideal product to replace gear couplings and general couplings today.

  The diaphragm coupling bolt connection does not need to be threaded on the connecting piece, the use is not restricted by the connecting piece, the structure is simple, and the disassembly and assembly are convenient.Stud bolts can be used in occasions where bolts cannot be used due to structural restrictions, but a compact connection structure is required.The bolt connection does not have a nut and has a smooth exposed surface, but it is not suitable for frequent disassembly and connection to avoid damage to the threaded hole.

  During the effective service life of the diaphragm coupling, the wedge-shaped gap surface that is inclined to each other needs to be maintained, lubricating oil is added, and the large opening enters the small opening.The two surfaces must have sufficient relative movement speed, the fluid must have sufficient viscosity, and the oil supply must be sufficient.In the maintenance process, it is important to grasp the basic scope of hydrodynamic lubrication, which is also the theoretical basis of sliding bearing design.
