Product Description
Rexnord Addax composite shaft systems are high-engineering flexible power transmission solutions specifically developed for industrial cooling towers, vertical pumps, and demanding applications requiring long-span power transmission. Manufactured from advanced carbon fiber composite materials instead of conventional steel shafts and metallic couplings, these systems combine lightweight construction with exceptional torsional strength.
In cooling tower applications, power transmission between the motor and gearbox is continuously exposed to humidity, chemical vapors, and significant temperature fluctuations. Addax composite shaft systems provide complete corrosion resistance, ensuring reliable and uninterrupted operation even in the harshest environmental conditions.
Key Technical Advantages of Rexnord Addax Composite Shaft Systems:
- Exceptional Strength with Lightweight Design: Up to 75–80% lighter than conventional steel shaft and coupling systems with comparable torque capacity, significantly reducing rotational inertia and dynamic loads on motor and gearbox bearings.
- Long Span Without Intermediate Bearing Support: Thanks to their high critical speed capability and low weight, the systems can span distances of up to 8 meters without requiring intermediate support bearings.
- Flexible Disc (Spacer) Technology and Misalignment Compensation: Specially engineered composite flexible disc (spacer) elements absorb angular and axial misalignment, minimizing vibration and reducing resonance throughout operation.
- Superior Corrosion, Chemical and UV Resistance: A specially formulated resin coating and UV-resistant exterior protect the shaft against sunlight, high humidity and cooling tower chemicals. Fasteners are manufactured from premium stainless steel or Monel as standard.
- Maintenance-Free Operation: Unlike gear couplings or metallic grid couplings, Addax composite shaft systems require no periodic lubrication. With no metal-to-metal wear surfaces, maintenance downtime and operating costs are significantly reduced.
- Fast and Safe Installation: The lightweight construction allows easy field installation and shaft alignment without cranes or heavy lifting equipment.
A properly engineered and precision-balanced Rexnord Addax composite shaft system minimizes vibration throughout the drivetrain, extends equipment service life, and significantly reduces total cost of ownership.
