Engineered Couplings
For Naval Applications

Ideal for:

• Main Propulsion layouts
• Water Jet drives
• Auxiliary power systems, pumps, compressors
• Weapons and munitions handling systems

Ameridrives Couplings and Bibby Transmissions have the broadest selection of coupling types available from any single manufacturer for virtually any naval application. Diaphragm, Disc, and Gear Couplings as well as Universal Joints, are all available to suit the performance requirements of the application. With Naval experience dating to the 1950’s Nautilus and Polaris programs, Ameridrives and Bibby engineers will work to understand the application parameters and develop the best coupling solution from the broad selection of types available.

Ameridrives Couplings Ameriflex® High Performance Diaphragm Couplings Used on most critical marine drives High torque to weight ratio High axial travel and misalignment capabilities Low repeatable unbalance Multiple separated diaphragms in a pack provide a built-in, fail-safe feature with no wearing parts Unlimited possibilities for customization for Naval applications Bibby Turboflex TurboFlex HP Couplings Torsionally stiff, light weight couplings Capable of being torsionally tuned to suit specific requirements High torques at high speeds, torque Rating: Up to 5300000 lb.in. (600 kNm) Significant levels of angular, radial, and axial misalignment allowable Easy to install, suitable for hostile environments, require no lubrication and feature a high torque to weight ratio No maintenance Standard and reduced moment designs available Extensive experience in Naval propulsion both in the US and Worldwide Ameridrives Couplings Gear Couplings Fully-crowned gear teeth provide operational benefits including maximum load-carrying capacity with minimum size, maximum reliability and long life Both “O” ring and metal seal models are available Strong, rigid floating sleeve Precision-machined identical hubs Positive dust-tight seals Over 50 years experience of custom couplings in US Naval applications including those under current development     Ameridrives Power Transmission Americardan® Universal Joints High torque capacity Long bearing life High operating angle capability One-piece yolk and bearing housing construction Heat treated alloy steel components 2 rows of roller bearings with lube fitting in center of cross Bearing caps are retained by snap rings Units are typically installed as a connection between engines and water jet drives
