MARINE ADVANCED PLANETARY TRANSMISSION PROGRAM DESIGN, MANUFACTURE AND TEST OF SYSTEM "A" AND "F", FINAL REPORT

This report covers engineering design, procurement and testing of large marine planetary transmissions at the Curtiss-Wright Wood- Ridge Facility. This contract resulted from earlier studies conducted by Curtiss-Wright which indicated that such designs could result in significant savings in the area of manufacture, installation, maintenance and operations when embodying the principles of modular construction and hardened and ground gearing. The units selected for development represent the final reduction stages for a total ship system and include the propeller thrust bearings as an integral part of the output shafts. The two units, System A of 40,000 SHP @ 105 RPM single shaft output and System F of 60,000 SHP @ 105 RPM contrarotating shafts output, were successfully tested for 450 hours up to 44,000 SHP, and proved satisfactory for ship installation.
