Single stage marine gearboxes with parallel, vertically arranged shafts (HUW) Single stage marine gearboxes with parallel, horizontally arranged shafts (HNW)

Gearbox designThe gearbox is of single stage type for drive by diesel engine via a flexible coupling or electric motor drive.

HousingGrey cast-iron. The oil sump is integrally cast. Also available with nodular cast-iron, cast steel or welded housings. The base of the housing can be adapted to the ship's structure.

Owing to the torsionally rigid construction with strong internal ribs elevated temperatures cannot impair the accuracy of tooth engagement. Special care has been taken to minimise vibrations and to avoid resonant surfaces.

BearingsAll shafts are supported in series-produced roller bearings. All bearings are lubricated and cooled with pressurised oil.

Thrust bearingsSeparate, series-produced roller thrust bearings; -one each for both forward and reverse travel. Both bearings are designed for lubrication and cooling with pressurised oil.

The bearings for forward and reverse travel can be inspected without dismantling the gearbox.

Gearing systemAll gear-wheels consist of highly wear-resistant case-hardened alloy steels. The involute helical gearing with optimal computer-controlled addendum modification

in accordance with the latest scientific findings is case-hardened and ground. Owing to its high capacity it has been possible to achieve compact, low-weight gear unit designs.

LubricationBy means of an attached gear-type oil pump. A screw spindle pump can also be supplied if required.

Cooling and filtrationAchieved with the aid of a seawater-proof oil cooler attached to the gear unit housing and a separate double filter with secondary magnetic filtration system. The cooler uses sea-water temperatures up to 32°C. Higher cooling water temperatures and coolers for brackish water or fresh water are available on request.

TubingComplete tubing to connect the attached pump, the oil cooler, the double filter and the appropriate fittings with all gear connection points are provided. The internal suction and spray tubes have outer flanges and can be checked without dismantling the gear unit. The suction tube fitting for the pump is provided above the bottom of the gear unit, in a readily accessible position. The line leading to the starting and standby pump and the cooling water supply lines are not included with the gear unit.

Gearbox input shaftWith cylindrical stub shaft, the length of which is adapted to coupling which can be fitted on request. If required, input shafts can be supplied for flange mounting or with an air hole for connection to a clutch.

Gearbox output shaftSupplied with a flange, the diameter of which depends on the gear size and can, on request, be enlarged. A borehole for taking control linkage for controllable pitch propeller can also be added.

Protection of gear unitOuter coat RAL 9005 or 9007.

Inner coat 13 AL 3000, fire red.

Internal protection by oil used in testing.

Instruments and valves1 thermometer before double filter 1 thermometer after cooler 1 pressure gauge before double filter 1 pressure gauge after cooler 1 non-return valve after integral pump 1 check valve after external pump 1 pressure relief valve before double filter 1 suction valve on suction tube of external pump

We are prepared to provide the gear units with all transducer instruments required for operation in accordance with the regulations of the relevant classification societies. Other instruments and fittings can also be provided as required.

Spare parts for coastal- or ocean-going vessels in accordance with the regulations of the classification societies and the table below.

Secondary PTO systems are available on request

HUW/HNW single stage marine gearboxes Lubrication and cooling

The integral gear pump normally supplies the gearing and the bearings with oil. The system is so designed as to ensure that sufficient oil is supplied even if the engine idles. Drive is via pump gearing and gearbox input shaft.

The independent pump, driven by an electric motor, is used to start the gearbox and as a reserve pump

A suction filler valve on the suction line of the integral pump ensures that the lines are always filled with oil even when the system is inoperative.

Before it reaches the cooler the oil is cleaned by a double filter with a secondary magnetic filtration system. The double filter is readily accessible and can be cleaned even while the gear unit is in operation.

A pressure relief valve in the line leading to the double filter ensures that the lubricating oil pressure cannot rise above a certain value. The integral gear pump and the free standing starting and reserve pump are separated by means of check valves.

The integral pump, the oil cooler, the double filter and the appropriate fittings are connected by tubes to all gearbox connection points. The internal suction and spray lines have outer flanges and can be checked without dismantling the gear unit. The suction tube connection for the integral pump is located just above the bottom of the gear unit, in a readily accessible position.

We supply all connecting lines shown in the diagram by full and chain-dotted lines, but not the suction and pressure oil fittings for the starting and reserve pump.

One thermometer and one pressure gauge are provided both before the double filter and behind the oil cooler so as to enable visual monitoring of the oil pressure and temperature.

We are prepared to provide the gear units with any monitoring instrument required for maintenance-free operation according to the regulations of the classification society concerned. Other instruments and sensors can also be installed, if required.
