Applications

MARINE PROPULSION DRIVES

Application expertise is the foundation of our marine propulsion business. For over 50 years, Allen Gears has been solving its customers design problems, often minimising the weight and installation space of its transmissions beyond the ability of its competitors.

We have the confidence to approach the boundaries of engineering limits, while still ensuring the ultimate in reliability. This is a result of intimate application knowledge and successful installations over many years.

Flexibility is the key
For each new project we have no preconception or preference for any particular engineering solution. In the early stages, only our customers’ design issues are important and we are at their disposal to optimise engine, propulsor and machinery layout to guarantee that vessel performance is optimised.

Flexibility to enable co-axial machinery layouts
Where a co-axial arrangement of engine and driven shaft is the customer’s optimum layout, the most complimentary gearbox configuration is likely to be epicyclic. These offer the most power dense solution where a single-in, single-out gearbox is required.

Flexibility to enable the most power dense machinery layout whilst achieving desired shaft centres
Where the optimum machinery layout calls for large centre distances between drivers, whilst minimising gearbox weight and dimension, Allen Gears will offer a tailored solution that achieves both aims.

Flexibility to enable any machinery orientation
Allen Gears will design the drive train and casing to ensure that the driving machinery, the driven machinery and surrounding structures can be positioned as desired.

Electron Beam Welding
Electron Beam Welding is applied in the construction of geared rotors and shafts to produce an extremely power dense solution. Allen Gears has worked closely with leading aerospace companies to develop designs and welding processes that ensure a robust and reliable product. The result is components weighing as much as 50% less than alternative light weight marine solution.

Electron Beam Welding allows precision gearwheels to be constructed from thinner section gear rims, side plates and shafts without generating the high levels of distortion prevalent with other welding practices.

• Electron beam welding does not use filler material
• Only parent material is utilised, providing a high level of weld integrity and strength properties

• Only highly localised heating is applied, minimising distortion.
