COMBINATION GEARBOXES

One of Allen Gears key assets is the ability to use our extensive knowledge of gear technology and application requirements to provide solutions that achieve the optimum transmission solution for the desired drivers. We achieve this through combining the transmission technologies of parallel shaft, epicyclic and bevel gearing to produce combination gearboxes that best meet the installation and operation requirements.

Such arrangements have been applied in the marine industry for a significant number of projects, where the use of epicyclic gears in combination with parallel shaft stages, have achieved significant gains in weight, space envelope and efficiency.

In applications where the general industry offering would be a parallel shaft gear only, Allen Gears have introduced epicyclic gears on high speed gas turbine and steam turbine drives to remove ratio at the high speed side of the transmission resulting in smaller and more lightweight solutions.

Applications of this type of technology have been utilised on a large number of high speed lightweight craft such as patrol vessels and hovercraft but also on high power bulk carriers in the marine sector.

SIGNIFICANT SIZE AND WEIGHT REDUCTIONS

In certain applications significant advantages can also be gained by introducing an epicyclic unit on the low speed side of a transmission, again yielding significant size and weight reductions. In this case the epicyclic gear's ability to shaft load over 3 or more gear meshes results in a much more torque-dense solution and can effectively replace the large bull wheels required on low speed high power drives.
