Reliable Power Generation on board Generator gearboxes can be used for the low-cost production of electricity on board. They are used with low-speed diesel engines and can be used for generator operation as well as for PTI/PTH operation (emergency operation). They can transmit power up to 8,000 kW. Installation is on the propeller shaft or on the front of the main engine. By integration of a gear unit a smaller and thereby lighter shaft generator can be used. It can be driven with high speed. 1,800 up to 3,600 rpm are common. FLENDER gear units have been used for this application, since many years, so far. The high material and manufacturing quality of our gear units results in a long service-life. Meanwhile, the gear units care for an unceasing operation of the generator.

Flexibility on Board Single input/single output marine gearboxes are used in river boats and coastal vessels, but also in ocean-going vessels. Depending on the application they can be built with vertically, horizontally or diagonally offset shafts. These gearboxes cover a power range from 1,000 to 30,000 kW with transmission ratios from 1.5 to about 12.1. These gearboxes can optionally be supplied with or without built-in multiple disk clutch. Using a PTO (Power Take Off), on-board electricity can be produced by a generator. Here, a variety of solutions is available to our customers. For example, the generators can be driven via a primary or secondary PTO. Special solutions such as PTI (Power Take In) or PTH (Power Take Home) are also possible, as are switchable or two-stage PTOs. To adjust the propeller speed in PTH operation, FLENDER provides a switchable PTO with two different transmission ratios.
