New Zero-Max^® ISO Adaptor Mount and Hub Options For CD^® Power-Series Shaft Couplings Provide A Wide Range Of Design Flexibility

Zero-Max offers an ISO Flange Adaptor in its new CD Power-Series Flexible Shaft Couplings, along with a variety of options for the opposing hub of the coupling. The ISO Adaptor Mount Flange is compatible with ISO 9409-1 mounting patterns commonly used on Precision Gear Reducers, Specialized Motors, Actuators, and Robotic Equipment.
 

CD Power-Series Couplings With Adaptor Mount Flange Are A Great Option For Use With Precision Gear Reducers

Precision Gear Reducers with an ISO Flange output configuration are built for high demand and high-performance applications, and the design and direct connection of the Zero-Max ISO Adaptor Mount Hub maintains the high torsional stiffness and positioning accuracy for the driven components in the system. This direct connection also makes for a more compact solution, providing smaller dimensions and savings on both weight and inertia in the system.
           
Some manufactures opt to make their own shaft adaptor to serve as a transition piece from the ISO flange bolt pattern of the Gearbox to connect to a traditional shaft coupling hub bore. However, these shaft adaptors introduce an added component and typically weaken the overall torsional stiffness of the system. This leads to a performance compromise that can be avoided. 

Some Precision Gear Reducers include a locating pin feature in the ISO mounting flange to maintain angular orientation of the components, if ever taken apart for service. For Gear Reducers having the locating pin feature, it may or may not be utilized in the actual application. In applications that require the use of the ISO 9409-1 locating pin feature, Zero-Max can add that feature to the Adaptor Mount option for the CD Power-Series upon request.

In addition to the ISO Flange Adaptors, the CD Power-Series Couplings are available with additional hub options, which provide design and mounting flexibility as needed for individual applications. These hub options include a Two-piece Split Clamp Hub, a One-piece Integral Clamp Hub, Non-ISO Flange Mounts, and Integrated Shrink Disc Hubs. “These options provide design flexibility and can be interchanged for a variety of configurations in order to meet the needs of virtually any application,” reports Scott Boersma, Director of Sales and Marketing at Zero-Max.
 
For the CD Power-Series product line Adaptor Mounts and Hubs:

• Adaptor Mounts are available to fit ISO 9409-1 bolt patterns ranging from 31.5mm up to 160mm diameter bolt circles.
• Larger size Adaptor Mounts can be made as a customized solution.
• CD Power-Series Coupling sizes range from a 2.17” / 55mm OD to an 8.47” / 215mm OD.
• Torque ranges from 371 in-lbs / 42 Nm up to 65,000 in-lbs / 7,345 Nm Continuous Torque Rating, with Peak Torque Ratings twice the Continuous Rating.
• Hub bores can support shaft diameters from 0.500” / 12mm on up to 5.1875” / 130mm. 
• Larger bores can be made available upon request. 
• Hubs are available as keyed or keyless to match the shaft condition in the application.
• Customization is available to tailor the product to specific application requirements and can include: Dimension Alterations for space or fit-up considerations, Special Disc Packs for higher torque capacity or higher torsional stiffness, Alternative Plating / Coatings for enhanced corrosion protection, Larger Sizes, and more.

Reasons customers are choosing the CD Power-Series include:

Zero-Max is a proven supplier of high-performance and durable products that provide trouble-free operation over a long lifetime. The new CD Power-Series Flexible Shaft Couplings offer a higher Power Density, providing more torque in less space.  These Servo-Rated Shaft Couplings feature high torsional stiffness (providing precise positioning accuracy and minimizing settling time in indexing or other start/stop applications) as well as a compact design that saves on space, weight, and inertia.  Available for keyed or keyless shafts, the variety of hub options and ease of installation make them ideal for most applications.
