Chosen for a 19,720-kW Ro/Ro ferry project were MAAG type MG- 150 W/P gearboxes. Two of the gear- boxes transmit the total 20 MW power developed by the Wartsila Diesel engines to two variable pitch KaMeWa propellers, to give the 538- foot ship a speed of about 22 knots. Each main gear train consists of two pinions that engage with an eight- foot diameter bull gear. Each gear- box weighs 25 tons complete with lubrications system. All rotating parts run in MAAG plain bearings. Additional PTO layshafts drive on-board generators with an output of 1.6 MW. Integral tilting pad thrust bearings with a thrust collar on each side of the bull gear take up the propeller thrust. The axial thrust is therefore trans- mitted directly from shaft to cast- ing, and hence to the foundations, resulting in a minimum of friction losses. MAAG gearboxes were cho- sen recently for another high-pro- file project, the building of the larg- est catamaran ferry ever for Stena. For the project, MAAG will supply a split power PROPJET Gearbox Sys- tem Type HPG-185/C system. A 50-ton crane capacity allows Cincinnati Gear to manufacture very large components, such as this 52,000-hp (39,000-kW), 140-rpm unit. Gears The Cincinnati Gear Com- pany, well-known for its marine reduction gears for military and commercial applications, has drawn upon its extensive gas turbine ex- perience to develop the "MA" series of gearboxes. These include a vari- ety of parallel shaft and epicyclic gearbox designs for gas turbine ap- plications of 1,000-hp and up. The gearboxes feature modular con- struction which permits them to be configured .in a variety of turbine- Hie One.The Only. The ORIGINAL The Simplex-Compact 2000 from Blohm+Voss AG & STI.
