Coupling designed with operational speed below ANF point

The 80” floating shaft coupling pictured is designed around Zero-Max’s CD Composite Disc technology bringing to bear several engineering disciplines. This coupling design was optimised such that the operational speed (2600RPM) is below the ANF point. That means that the coupling will never go through the critical speed and always operate in a sub-critical speed.

Key to this design is the accurate prediction of the axial natural frequency point based on Zero-Max’s composite flex disc performance. Connecting to these custom discs are 316 stainless steel hubs passivated for extra cleanliness required for the application. A 3x80” thin-walled alloy tube connects the two coupling assemblies at each end for mounting in the motion system.

Zero-Max applied to this and many other custom coupling applications include: metallurgy and alloy material design, composite disc formation, disc deflection control, precision fastening of components and dynamic coupling balancing. These engineering disciplines required precise control of tube stiffness, stiffness properties of the composite disc and overall weight of the coupling assembly.

A wide range of custom CD couplings available

System designers needing a robust coupling for challenging applications will find Custom CD Couplings combine the highest torsional stiffness and high load capacity better than any other coupling.

Custom designs include couplings handling high power in a small space, blind fit couplings, large scale floating shaft couplings, high misalignment and high torque couplings, high speed couplings, high precision small package couplings, plus many more.

Zero-Max is ideally qualified as the premier supplier of custom couplings. The technology of the Composite Disc design and the 50-year application acumen of Zero-Max Engineers work together to provide a superior solution for the most demanding coupling needs.
