3 General information marine gearboxes Single input / Single output gearbox Vertical, horizontal or diagonally offset shafts. PTO (Power Take Off) is provided to generate Inexpensive on-board current. PTH option also available. As standard, all gearboxes are equipped with an oil supply and monitoring system Power rating from 1,000 to 30,000 kw Ratio from 1.5 to 12:1. The propeller shaft thrust bearings are fitted into the gearbox. Housings of torsionally rigid design, which also ensures perfect meshing of the gear teeth under any condition Slide 3

4 General information marine gearboxes Twin input / Single output gearbox Primary PTO s are provided, i.e. the multiple disk Clutches which are fitted for connecting or Disconnecting an engine Design with primary or secondary PTO Quillshaft design at more than 10,000 kw Two-speed PTO s can be used to achieve higher Propulsion flexibility. Power rating from 1,000 to 45,000 kw Ratio from 2 to 6:1 Slide 4

5 General information marine gearboxes Generator drive gearbox Generator gearboxes for the generation of inexpensive on-board current are built as separate gearboxes in connection with low-speed diesel engines, and are arranged in the propeller shaft line or on the main engine face. Two-speed generator gearboxes for PTO/PTI operation also available. Power range up to 10,000 kw Slide 5
