Features of diaphragm coupling

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

2. Zero turning gap;

3. Has oil resistance and characteristics;

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

5. The characteristics of clockwise and counterclockwise rotation are 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.

The diaphragm coupling 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 advantages of driven torque transmission, elastic vibration, no noise, and no lubrication are the ideal products to replace gear couplings and general couplings.

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 service life of the diaphragm coupling, it is necessary to maintain the wedge-shaped clearance surfaces that are inclined to each other, add lubricating oil, and enter the small opening from the large port.The two surfaces have sufficient relative movement speed, the fluid has sufficient viscosity, and the oil supply is sufficient.In the maintenance process, it is important to grasp the basic scope of hydrodynamic lubrication.
