Couplings for high power applicationsFor high power applications, customised high torque CD couplings up to 20 inches in diameter handling 78,000Nm peak torque are now available from Zero-Max. Available to system designers seeking the most robust coupling for very large and challenging applications, these 'super sized' couplings combine the highest torsional stiffness and high load capacity in this coupling design to date.
With torsional stiffness of 419,000Nm/DEG and continuous torque of 39,000Nm, these CD couplings have angular misalignment capacity of 1.5 degrees with axial misalignment of 6.5mm and parallel misalignment of 0.24mm. Designed around the composite centre disc, super-sized CD couplings perform at these peak torques in the most hostile operating environments - from extreme cold to hot weather conditions -57°C to +121°C. Time-proven applications include drive trains, gear boxes and generators providing trouble-free operation in sea water and abrasive desert sand conditions.
The coupling's composite centre disc is manufactured to strict aerospace and Six Sigma practices. The hub material is 1045 HR steel with fasteners made of titanium 6AL4V grade 5 materials. All components are tested with Finite Element Analysis (FEA) software for predict-able characteristics. Kevin Wells, Zero-Max regional sales manager says: "The demand for super-sized CD couplings is growing rapidly, especially in different areas of the energy industry. We see this as an important new trend and are pleased to do our part in making this industry more productive and efficient using our coupling technology."
