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 fed from the large port to the small port. The two surfaces must have sufficient relative movement speed, the fluid must have sufficient viscosity, and sufficient oil must be supplied. In the maintenance process, it is important to master 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 compact connection structures are 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.
