Recently, SKF (SKF) launched a series of diaphragm coupling, medium torsional stiffness and above the high torque applications provide economic and lubrication free service. SKF diaphragm coupling in a variety of configurations (including single disc, double disc, and horizontal and vertical installation of the ring gasket) with up to 178 kNm of the load range, for a wide range of applications has brought great benefits.

“Many devices are exposed to the natural environment, so the quality of the parts is needed to ensure the smooth running of the equipment.” SKF global power transmission technology manager David Beggs said. “SKF diaphragm coupling with all steel mechanical components, with a stable performance, easy for customers to easily cope with high speed applications. It also has two plane dynamic balance, which is usually applied to a higher speed.”

The SKF diaphragm coupling is composed of two wheels and a composite stainless steel diaphragm component which is fixed by a series of mounting bolts (retained by the built-in locking nut). SKF diaphragm coupling can bear a certain misalignment, and no need for lubrication, and therefore can minimize the maintenance requirements. The single disc type diaphragm coupling can be adapted to the angle deviation, and the double disc component unit with the ring spacer can be allowed to be angle, parallel or in combination. Disc components or ring gaskets can be installed and removed in the radial direction, which means that the user does not need to move the original motive and drive device.

SKF diaphragm coupling hub guide hole simplified borehole requirements, bringing high performance and considerable cost benefits, including the petrochemical industry (direct drive type wind machine transmission device, pumps and compressors, printing and paper industry (positioning), plastic industry, power plant (high speed turbine drives, AC generator, pump, refrigeration industry (compressor) and shipbuilding industry for a range of applications and industries.
