Amarillo Gear Company, a leader in the design and manufacturing of gear drives for mechanical draft cooling towers and air cooled condensers, now offers the Amarillo Composite Drive Shaft product line for cooling tower service.





Our many years of experience in cooling tower power transmission systems
provided this natural extension into designing and manufacturing composite
drive shafts. Each drive shaft connects the electric motor to the gearbox
input shaft, thereby transmitting torque to rotate the cooling tower fan.
These drive shafts must accommodate spans ranging from 2 feet
in small HVAC towers, to over 20 feet in large field erected towers.

Amarillo Gear has always been a leader in new and innovative products
for the cooling tower and heat exchanger industries. We listen to what the
problems are, and then design our products to provide superior performance.
Based upon customer surveys and input from cooling tower industry
professionals, Amarillo Gear has designed, manufactured and tested
its composite drive shafts to incorporate the following features and benefits:

Comparison with Steel Drive Shafts
Features Benefits
High Strength to Weight Ratio Composite center spacer member weight is a mere fraction of the weight of a steel drive shaft center member.
Inherent Corrosion Resistance Composite materials have corrosion resistance exceeding that of 316 stainless steel.
Long Spans Eliminates requirement for high maintenance and costly intermediate pillow block bearings.
Patented Composite Flex Disc Low maintenance; no fretting corrosion of steel "shim" packs, plus much easier installation and maintenance.
Dimensionally Stable Very low Coefficient of Thermal Expansion (CTE).
Vibration & Shock Control The natural dampening of composite materials reduces the transmission of vibration throughout the power train, resulting in less wear and tear on mechanical equipment.


Comparison with Other Composite Drive Shafts
Features Benefits
Greater Misalignment Capacity When misalignment occurs due to mechanical equipment shifting, greater than one degree of angular misalignment per flex disc allowed.
Composite Flex Discs Color coded by size for easy identification. Includes integral 316 SS bushings.
Regsitered Bushings & Flanges Lower stress concentrations and better assurance of alignment.
High Strength Composite Flange Hubs Spacer tube flange hubs are strong and corrosion resistant, while at the same time lightweight, reducing overhung loads.
316 SS Flange Hubs Corrosion resistance of stainless steel for motor & gearbox hubs.
Standard 316 SS Hardware Since precision hardware is not required, fasteners are easily replaced, and at lower costs. Optional monel hardware available.
High Service Factor Rating Capable of withstanding repetitive high start-up torques.
Durable UV Resistant Coating Longer lasting protection from UV degradation.
Balancing All drive shafts are dynamically balanced to AGMA 9000-C90, Class 9 specifications.
Process Verification Each Amarillo composite drive shaft is tested to 4 times continuous operating torque prior to shipment.
Easier Installation Fewer parts required at each flex disc connection.
Special Shipping Tubes Designed to give ultimate drive shaft protection for both international and domestic shipments.
