Disc couplings for high torque ­applications

4th Quarter 2018 Shaft power components

SKF’s range of disc couplings in a variety of configurations offer cost-effective, lubrication free service in medium to high torque applications that require torsional rigidity. They consist of two hubs and a laminated stainless steel disc pack secured by a series of fitted bolts retained by nylon insert lock nuts. The couplings feature a capacity range up to 178 kNm in a variety of configurations including single disc, double disc and spacer for both horizontal and vertical mounting.

“In many applications, the challenge posed by exposure to the elements requires quality parts that continue to operate smoothly,” says power transmission global technical manager, David Beggs. “The SKF disc coupling offers robust performance, with all-steel machined components that allow for high-speed applications to be handled with ease. With two-plane dynamic balancing, higher speeds are often permissible.”

The couplings minimise the need for maintenance because they offer some allowance for misalignment and do not require lubrication. Single disc couplings accommodate angular offset, while double disc pack units with a spacer will allow for angular, parallel or combined offset. The disc pack or spacer may be removed and re-installed radially, meaning the prime mover and driven machine need not be moved at all.

With hub pilot bores to simplify boring to requirements, the disc couplings bring cost-effective performance to a range of applications and industries including petrochemical (direct drive fan drives, pumps and compressors), printing and paper (positioning), plastics, power generation (high-speed turbine type drives, alternators, pumps), refrigeration (compressors) and marine.
