Wärtsilä double input, single stage reduction gears connect two engines to a single propeller shaft and cover a power range from 2,000 to 25,000 kW. The gears are available with a horizontal offset between the input shafts and output shaft to allow two (diesel) engines to be connected.
Double input gears are applied to combine the output power of 2 medium speed diesel engines on a single propeller shaft. Typical applications include:
A key dimension of a double input gear is the horizontal offset, which is determined by the required service space between the two propulsion engines. Wärtsilä double input gears can be combined with Wärtsilä engines, as indicated in the table below, as well as with other engine brands.
