Throughout the life of a gearbox, operating requirements and conditions can change significantly.
Allen Gears Services is skilled in assessing the suitability of a unit within a current project and suggesting improvements and upgrades to offer increased reliability, ease of maintenance or increased power through a plant.
Whether there is an existing unit in a package which requires a change in duty, or a unit which has continual failures, Allen Gears will visit the site, technically assess the unit and design and fit new components as required; if necessary to fit into existing gear cases or space envelopes.
Recent upgrades have taken place on a number of units including increasing power to compressors, offering replacement units to increase power generation, or changing duty from power generation to test cells.
Reverse engineering
Typical calculations involved in any upgrade or reverse engineering programme include:
• Special purpose data sheet (AGMA 6001- H98)
• Interference fit gearwheel / shaft
• Thermal growth calculations
• Tip and end relief requirements
• Gear tooth particulars
• Summary of power losses
• Pinion torsion and bending deflection
• Inertia and stiffness values
• Bearing performance
• Thrust bearing (location)
• Detailed drawings of pinion, gearwheel & shaft bearings etc.
• Routings for material in manufacture
• No load full test procedure
Allen Gears Services has a particular skill in reverse engineering components. We can re-engineer, and then provide either exact replacements, or alternatively design replacements to AG standards which will offer the assurance of our design expertise and practices, whilst still fitting within the space constraints of the package. Our dedicated engineering team of designers are highly skilled and have vast experience of reverse engineering a range of components and complete gearboxes. |
