During the effective service life of the diaphragm coupling, the wedge-shaped clearance surfaces that are inclined to each other need to be maintained, lubricated, and discharged from the large port into the small port.The two surfaces have sufficient relative movement speed, the fluid has sufficient viscosity, and sufficient oil is required.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.
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.

Maintenance method of diaphragm coupling:

1. Before installation, clean the end faces of the two shafts and check the fit of the key grooves on the end faces;
2,Diaphragm couplingAfter installation, all screws must be checked for normal operation during a shift. If they are found to be loose, they must be tightened. Repeat this several times to ensure that they will not loosen;
3. In order to prevent the diaphragm from running at high speedFretting wear, Resulting in micro-cracks and damage to the diaphragm bolt holes, you can coat between the diaphragmsMolybdenum disulfideWaitSolid lubricantOr apply anti-friction coating to the surface of the diaphragm;
4,Diaphragm couplingLong-term overload use and operation accidents should be avoided;
5,Diaphragm couplingDuring work and operation, check whether the diaphragm coupling is abnormal. If any abnormality occurs, it must be repaired;
6. The diaphragm coupling may cause personal damage due to the operating diaphragm coupling.Equipment accidentAppropriate safety precautions must be taken at each site
