Kop-Flex’s new High Performance Disc Coupling 2.0 redefines “high performance” with a lighter-weight, second-generation design aligned to the torque requirements of turbomachinery equipment. Introduced and exhibited at the Turbomachinery show in booth 2111, the new disc couplings are 15-30% lighter than previous generations and competitive designs. Engineering optimization of the disc pack, hardware and major components achieves significant reductions in weight and stress concentrations in the assembly, while conforming to API 671 4th Ed. requirements. 
In addition, the expanded range of 22 sizes is ideally matched for established English and metric shaft sizes to allow selection of the smallest, lightest coupling needed for an application’s torque requirement and service factor. Two reduced-moment styles are available: the standard RZS and the full featured RMS, which includes interlocking flanges for additional safety in the event of torque overload. The minimum nominal bore capacity for both RMS and RZS models is 40mm to 210mm, with maximum continuous torque ratings of 12,000 lb-in to 1,880,000 lb-in for both designs. Maximum speeds for both models range from 7,900 rpm for the largest coupling to 34,300 rpm for the smallest.
Julian Del Campo, Regal Senior Product Specialist made a statement that explained that the Kop-Flex High Performance Disc Coupling 2.0 uses refined classical stress calculations and advanced finite element analysis and the FEA model used 26 million degrees of freedom and required more than 500 days of problem solving during the process.
The new disc-pack geometry on the product improves the stress distribution and reduces reaction loads on the equipment. The lighter coupling and increased range of sizes allow us to match common customer shaft sizes and decrease the use of high-cost titanium parts.
Kop-Flex high performance disc couplings have provided over 100 million hours of reliable operation. Hubs, sleeves and spacers are heat-treated 4340 steel, while the flexible elements are a series of corrosion-resistant, high-strength, stainless steel discs coated with Koplon. Optional coupling features include; Powerlign Torquemeters, lateral and torsional tuning, electrical insulation and shear spacer sections
