Development Engineer / Lead Designer - Planetary Gearbox
HybridBudapest, Budapest, Hungary
Job Summary
Define planetary gear architecture based on torque, ratio, and space constraints. Perform analytical calculations for tooth stresses, bearing loads, and deformations. Optimize tooth geometry for NVH, efficiency, and durability. Select materials and heat treatments for gears and planet carriers. Lead 3D CAD modeling and drawing creation. Ensure manufacturing and assembly aspects are integrated into designs. Collaborate with subsystem managers for seamless integration. Review and approve designs. Troubleshoot and conduct root cause analysis for gearbox problems. Observe market trends in planetary gear technologies and manufacturing processes. Requires 5+ years of gearbox development experience and in-depth knowledge of gear theory and CAD software.
Required Qualifications
- Bachelor's or Master's degree in Mechanical Engineering or related field
- Long-term (5+ years) relevant experience in the field of gearbox / planetary gear development
- Experience and profound expertise in industrialization of gears, running, spline connections, shafts, rolling, plain bearings, freewheels, shaft-hub connections
- In-depth knowledge of related manufacturing technologies such as machining, turning, milling, heat and surface treatment, hard machining
- Extensive knowledge of gear theory
- In-depth knowledge of kinematics, dynamics, material sciences and CAD software
- Motivating communication (technical leadership)
- Clear, structured, and systematic way of working
- Definition of the planetary gear architecture (e.g. Ravigneaux, Lepelletier, Simpson, etc.) based on the gearbox requirements (gear ratios, torque capacity, installation space)
- Performing detailed analytical calculations for tooth stresses (bending, surface pressure), bearing loads and component deformations
- Optimization of the tooth geometry (profile shift, helix angle, pressure angle) with regard to NVH (noise, vibration, roughness), efficiency and durability
- Selection of suitable materials and heat treatments for gears and planet carriers
- Leading the 3D CAD modeling and creation of drawings for all planetary gear components
- Ensuring the consideration of manufacturing and assembly aspects in the design
- Collaboration with other subsystem managers (actuators, bearings, housing, system) to ensure seamless integration
- Review and approval of designs
- Troubleshooting and root cause analysis for problems related to the planetary gearbox
- Continuous market observation of planetary gear technologies and manufacturing processes
- Consideration of NVH aspects in the design
