JMJ double diaphragm coupling maintenance needs to master the theory

JMJ double diaphragm coupling in the course of the specified service cycle, the coupling parts are required to maintain each other inclined wedge clearance surface, and to add lubricating oil, need to be from large mouth into small mouth out. Below you can follow the manufacturer's small series to understand the maintenance of JMJ type double diaphragm coupling lubrication need to master the theoretical basis.

JMJ double diaphragm coupling in the effective life cycle, need to maintain the oblique wedge clearance surface, add lubricating oil, from the big mouth into the small mouth out. The two surfaces need to have relative velocities, the fluid needs to have a specified viscosity, and the oil supply needs to be adequate. In the maintenance process, it is more important to master the basic category of hydrodynamic lubrication, which is also the theoretical basis of sliding bearing design. The JMJ double diaphragm coupling actively compensates for the axial, radial and angular offset caused by the motor, as well as the effects caused by factors such as manufacturing errors, installation errors, bearing deformation and temperature rise. It belongs to the flexible coupling in the metal elastic components, from the motor transmission torque, elastic vibration, no noise, no lubrication advantages are the current replacement gear coupling and general coupling use of common products.

JMJ double diaphragm coupling in the use of its bolt connection is not required to be connected on the cutting thread, and the use is not limited by the connector, simple structure, convenient disassembly and assembly. Stud bolt can be used in the case that the bolt cannot be used due to structural limitations, but the connection structure is tight. Bolt connections without nuts and polished exposed surfaces are not suitable for frequent removal of connections to avoid damage to threaded holes.
