Disc Elastic Coupling Operating Characteristics

Disc elastic couplings can transmit large torque, and have the advantages of simple structure, easy processing, and no need for lubrication. Therefore, they are widely used in ships, petrochemical industry, machinery manufacturing and other fields.

Elastic disc couplings can absorb axis offset through the flexibility of the disc packs. Under the same working conditions, diaphragm elastic couplings can transmit larger torques, and have simple structure, easy processing, and no need for lubrication. Advantages; The disc elastic coupling can bend and twist under various deviations. The rigidity of a diaphragm elastic coupling is also affected in the same way when subjected to torsional loads. The disc packs is the key component of the disc elastic coupling. Since the stiffness of other parts in the diaphragm elastic coupling is much greater than that of the disc component, the stiffness of the diaphragm component can be regarded as the stiffness of the diaphragm elastic coupling. Because during operation, the disc elastic coupling will produce axial deviation, transmit torque, withstand centrifugal force, etc., the diaphragm assembly is in a complex stress state when working.

The torque of the diaphragm elastic coupling is input from the driving end hub, and is transmitted to the disc packs through the main transmission equispaced bolts. The disc packs then transmits it to the intermediate spacer through the bolts, and is also transmitted by The disc packs, bolts and driven end hub output at the other end. The metal diaphragm is a key component of the disc coupling. It is composed of metal diaphragms stacked together to form a disc packs, through which torque and motion are transmitted. The disc packs is composed of a different number of thin stainless steel-coated discs. It transmits torque and the two shafts connected by the diaphragm coupling. Due to manufacturing and installation errors, load-bearing deformation, thermal deformation and machine base Due to sinking and other reasons, there will be a certain degree of axial, angular and radial offset between the shafts. The relative offset of the shafts will cause additional loads on the shaft, bearings and couplings, making the unit's working conditions. The coupling can absorb the three-way deflection between the axes through the flexibility of disc packs.
