Update: The new standard is ANSI/AGMA 6032-B13 Standard for Marine Gear Units: Rating and Application for Spur and Helical Gear Teeth.
Members of the AGMA Helical Enclosed Drives Marine Units Committee are currently revising ANSI/AGMA 6032-A94
This committee evaluates the design, rating and application of enclosed drives in which helical gears are the principal form for propulsion and/or ship service generator sets. If you would like to become involved with the valuable work of the AGMA Helical Enclosed Drives Marine Units Technical Committee, email aboutaleb@agma.org or call AGMA Headquarters at (703) 684-0211 for details.
ANSI/AGMA 6032-B13 is applicable to marine reduction and reversing gears as follows:
- marine propulsion reduction gears driven by internal combustion engines or electric motors from 1500 to 20 000 horsepower (1120 to 14 900kW) per prime mover, when the rotor speeds do not exceed 3600 rpm.
- marine propulsion reduction gears driven by steam or gas turbine from 1500 to 30 000 horsepower (1120 to 22 370 kW) per prime mover.
- power take–off (PTO) gearing that is integral to the propulsion unit.
- auxiliary propulsion gears.
- combination of drives listed above.
The fundamental rating formulas are applicable for rating the pitting resistance and bending strength of external spur, helical, or double helical involute gear teeth. The formulas evaluate gear tooth capacity as influenced by the major factors which affect gear tooth pitting and gear tooth fracture.
This standard also addresses bearings, clutches, lubricating oil systems, shafts and certain aspects of vibrations.
