Couplings enable smaller machine designs
The quest for smaller machine footprints continues as designers seek new ways to reduce machine size while increasing output. The Zero-Max CD coupling pictured provides precise and reliable shaft connections in less space than other couplings. It operates without fatigue for reliable 24/7 operation required in the latest machine designs.
Key to this CD coupling design is the composite flex element. It provides high torsional stiffness, yet allows for misalignment in high stress applications. In addition, these zero-backlash CD couplings provide smooth operation at high speeds. The coupling’s high performance material is configured in a compact design like that pictured surpassing the performance of much longer couplings. The resulting space savings enables machine designers to reduce the foot print saving valuable floor space.
Focusing on the coupling pictured, Zero-Max highlights a torque rating of 76,800 in-lbs from a coupling that measures 12in in diameter and 4.5in in length, and which weighs 43.9 lbs. Torsional stiffness is 25,000 in-lbs per degree, while design speed is 5,000rpm. The coupling has been specifically engineered to operate in sub critical speed. Further characteristics include a maximum angular misalignment of 1.5 inches, maximum radial misalignment of 0.045 inches and maximum axial misalignment of 0.200 inches. Coupling inertia is 984 lb-inch2.
Designed around Zero-Max’s unique composite centre disc, Compact CD couplings perform at peak torques in the most hostile operating environments, from extreme cold to hot weather conditions of –57° 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.
