Carbon fibre couplings reach out


‘Fit- and- forget’ carbon fibre disc couplings are ideal for use on cooling tower fans,  vertical pumps, marine drives, and high speed test beds.

Bibby has developed composite, carbon fibre versions of its market-leading Torsiflex shaft couplings for use on equipment such as cooling tower fans, large vertical pumps, marine drives, high speed test beds and performance car engine dynamometers. The unique ability of the composite couplings to operate over long lengths – up to 30-metres in one application – 10-m plus without central bearings, combined with their inherently low-mass and generous misalignment capacity, keeps maintenance of the equipment to a minimum. As a result, the couplings are virtually "fit & forget" units.

Bibby’s range of composite tube disc couplings have been designed using the latest material technology - providing lower mass and greater strength. The couplings are highly stable, lightweight units ideally suited to operating over longer lengths than equivalent metal type couplings. They are easier to install, do not require support bearings or lubrication, and are essentially maintenance- free.

The ability of the Bibby composite tube disc couplings to cover long spans without the need for central bearings and their inherent low mass can considerably reduce maintenance costs on equipment to which the couplings are installed. This feature is particularly advantageous on cooling tower fan drives, and in remote operated or inaccessible plants such as water and sewage pumping stations employing deep well pumps.

The same design features of low mass and the ability to handle long spans without support, combined with minimal levels of vibration, also make the Bibby composite couplings the first choice in many applications where conventional couplings have been inappropriate: on high speed engine test beds, for example, and on ship and hovercraft propulsion systems.                                              

The composite Turboflex tubes are filament wound on accurate mandrels using computer controlled machinery, and are cured whilst on the mandrel. This results in high accuracy in respect of tube dimensions, roundness and straightness; all of which contribute to an extremely high quality product that can deliver excellent operating reliability Purpose- developed software enables Bibby Turboflex to offer tubes with fibre windings at angles adjusted to give the optimum performance for specific lateral critical, torque and torsional stiffness requirements. In addition, Bibby offers the option to wind tubes using a variety of fibres: Carbon Fibre, Glass Fibre, Carbon/Glass Mix and High Modulus Fibre, all of which provide specific advantages in their relevant operating areas.
