Scope

The requirements of this Chapter, except where otherwise stated, are applicable to engine gearing for main propulsion purposes and for engine gearing for driving auxiliary machinery which is essential for the safety of the ship or for safety of persons on board where the transmitted powers exceed 220 kW for propulsion drives, and 110 kW for auxiliary drives. Alternatively, calculations using the methods defined in ISO 6336 – Calculation of load capacity of spur and helical gears will be considered. In any mesh, the terms ‘pinion’ and ‘wheel’ refer to the smaller and larger gear respectively. Bevel gears will be specially considered on the basis of a conversion to equivalent helical gears. For torsional vibration requirements, see Pt 5, Ch 6, 2.3 Scope of calculations.
