EPICYCLIC GEARBOXES (PLANETARY GEARBOXES) FOR THE POWER GENERATION INDUSTRY

Allen Gears are internationally recognised as the leading manufacturer of epicyclic gearboxes. They offer standard Stoeckicht epicyclics as well as their own innovation, the Advanced Epicyclic Gear (AEG). The AEG eliminates the need for an inner coupling ring allowing a simpler, more efficient gearbox.

Benefits of the epicyclic gearbox include:

• High levels of mechanical efficiency
• Compact lightweight gearbox solution
• Reduced noise levels due to lower pitch line velocity
• A multitude of mounting options
• Co-axial shaft arrangement

PARALLEL SHAFT GEARBOXES

Parallel shaft gearboxes complement Allen Gears' range by offering a high specification gearbox solution suitable for applications up to 45MW. Particularly suited to high power, low ratio packages, the advantages of multipurpose parallel shaft gearboxes include:

• Vertical and horizontal offset
• Design simplicity and access for instrumentation
• Widely understood technology - applicable to AGMA and API specifications
• Option for PTOs/PTIs including starter and barring systems
• Option for common generator and gearbox oil system
• Option for high and low speed quill shafts

UNIQUE GEARBOX CONFIGURATIONS FOR OPTIMUM POWER

Sometimes gearbox configurations necessitate unique gearbox solutions. Allen Gears are skilled at designing and manufacturing tailor-made solutions to meet specific system specifications. A number of different options that provide optimum performance include:

• Combination parallel shafts and epicyclic units
• Two-stage parallel shaft units - typically used in marine applications
• Cradle gearboxes for test stands
• Two inputs and one output and reverse options
