The bolt connection of JM single diaphragm coupling does not need to be cut on the connector thread, and in 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.

JM type single diaphragm coupling in a long service cycle, is the need to maintain the oblique wedge clearance surface, add lubricating oil, from the big mouth into the small mouth out. The two surfaces have enough relative velocity, the fluid has enough viscosity, and the oil supply is sufficient. In the maintenance process, it is important to master the basic category of hydrodynamic lubrication, which is also the theoretical basis of sliding bearing design. The JM single 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. The coupling transmission part belongs to the flexible coupling in the metal elastic components, from the motor transmission torque, elastic vibration, no noise, no lubrication is the ideal product to replace the gear coupling and general coupling.

JM single diaphragm coupling system gradually develops towards the direction of heavy load. People have realized the seriousness of the misalignment problem of coupling products, and called many scholars to carry out relevant theories and tests, but mainly focused on the misalignment of diaphragm coupling needs to be seen in various literatures.
