Low Inertia Aluminum CD® Couplings From Zero-Max Can Reduce Cycle Time And Increase System Productivity

“We surveyed design engineers to find out what was the most desirable feature when
specifying couplings for servo motor applications,” reports Robert Mainz, Zero-Max sales
manager. “Low inertia was the most important.” These engineers said they continually look for
ways to reduce cycle time and improve system productivity. A lightweight yet high strength
coupling design will enable the designer to increase the speed of the actuator. The combination of the lightweight aluminum hubs and unique composite disc provides the necessary
characteristics to increase speed and cut cycle times. Lightweight couplings will also have an
effect on the energy consumption in their designs. The aluminum CD® couplings meet those
objectives and more.”

The CD® coupling has a very robust yet lightweight aluminum design with the working
part made of a special composite material. The composite disc design withstands the stresses
of a servo motor’s high acceleration rates and high torque capacity better than other coupling
designs. This results in lower energy requirements, and longer life of the motor and other
operating components while ensuring uninterrupted system operation.

Applications include automated packaging systems and assembly machinery where
precise, high speed positioning is required.

Zero-Max CD couplings are available in single and double flex models with or without
keyways. The double-flex version is for precision applications requiring misalignment capacity
greater than the single flex design. The single flex models have a torque capacity range from 40
Nm to 1436 Nm and beyond with speed ratings from 4400 RPM to 17,000 RPM.

Zero-Max will design and build custom CD couplings to handle virtually any difficult
application. All CD couplings are environmentally friendly and are manufactured of RoHS
compliant materials.
