NAVILUS Single Input/Output Marine Gearboxes: Reliable, efficient for single-engine marine propulsion.
NAVILUS Single Input / Output Marine Gearboxes, developed by Flender, are specialized marine gear units designed for single-engine ships, serving as a core component of marine propulsion systems[1[5]].
Constructed with premium industrial materials and precision manufacturing, the gearboxes feature torsionally rigid housings that ensure stable gear meshing even in rough seas, with built-in propeller shaft thrust bearings to transmit propeller thrust[2[3
Key specifications include a power rating range of 1,000 to 30,000 kW and transmission ratios from 1.5:1 to approximately 12:1, catering to diverse single-engine vessel needs[1
Core advantages include minimal noise and vibration, highest transmission efficiency, and an optimum power-to-weight ratio, enhancing on-board comfort and reducing operational costs[1[
Common applications include river boats, coastal vessels, and ocean-going ships, all equipped with single-engine systems
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.
NAVILUS Generator Gearboxes: Reliable marine gearboxes for on-board power generation and emergency use.
NAVILUS Multiple Input/Single Output Marine Gearboxes: Flexible, high-efficiency for multi-engine ship propulsion.
