Key Responsibilities:
1. Gearbox Design & Development• Lead the conceptual, detailed, and final design of railway gearboxes (axle-hung, nose-
suspended, fully suspended, final drive, auxiliary gearboxes).• Perform gear train design and optimization (helical, spur, bevel) including:
o Gear ratios, torque transmission, efficiency
...
o Noise, vibration, and harshness (NVH)
o Fatigue life and reliability calculations
• Design gearbox housings, shafts, bearings, seals, lubrication systems, and mounting
interfaces.
• Ensure compliance with railway operational duty cycles, shock loads, thermal expansion,
and environmental conditions. 2. Materials Engineering (Critical Focus)
• Select appropriate materials for gears, shafts, housings, bearings, and fasteners, based
on:
o Fatigue strength
o Wear resistance
o Toughness
o Corrosion resistance
o Thermal performance
• Define heat treatment processes, such as:
o Carburizing, nitriding, induction hardening
o Quenching and tempering processes for gears and shafts
• Evaluate and recommend advanced materials and surface treatments, including:
o Alloy steels (e.g., CrMo, NiCrMo, etc)
o Cast irons and cast steels
o Aluminium alloys (where applicable)
o Coatings (shot peening, DLC, anti-scuffing, corrosion protection, etc)• Collaborate with materials and metallurgical teams on failure analysis and root cause
investigations.
3. Manufacturing Processes & DFM/DFA
• Ensure Design for Manufacturing (DFM) and Design for Assembly (DFA) principles are
applied throughout development.
• Define and validate manufacturing routes for gearbox components, including:
o Forging, casting, machining, grinding
o Gear cutting (hobbing, shaping, grinding, etc)
o Heat treatment and distortion control
• Work closely with suppliers and manufacturing plants to:
o Review manufacturability risks
o Optimize cost and lead times
o Resolve production quality issues
• Support process validation, pilot builds, and series production ramp-up.
4. Engineering Analysis & Validation
• Perform or guide strength, fatigue, and thermal calculations for gearbox systems.
• Use or review FEA and analytical methods to validate design of gearbox components,
Gears, Housings, Shafts, Bearings, etc.
• Define test plans for type testing, endurance testing, and validation per railway standards.
• Analyse test results and implement design improvements.
5. Standards, Compliance & Safety
• Ensure designs comply with applicable international and regional railway standards, such
as: EN, IEC, ISO; UIC; AAR
• Apply RAMS (Reliability, Availability, Maintainability, Safety) principles.
• Ensure gearbox designs meet life-cycle requirements (typically 30–40 years).
