Job Description: Lead Gearset & Planetary design for e-Axle transmission projects, including acquisition, customer, and innovation projects, ensuring “ON Spec, ON Time, ON Cost” Evaluate Transmission Endurance & Overload Requirement & develop Cost & Performance optimal solution Own concept to B/C/D Sample design release of gearsets and planetary gear trains for e-Axle transmissions, ensuring durability, NVH, efficiency and package compliance. Lead cross-functional integration for Gearset realization with FEA, Testing, Purchase, Supplier ,Quality and Manufacturing for B & C & D sample Perform Macro-geometry sizing (module, face width, helix, pressure angle) to meet vehicle targets and e-Axle duty cycles. Perform Micro-geometry design & profile optimization (crowning, lead correction) using MASTA/ROMAX/KISSsoft; LTCA and scuffing/pitting checks. Execute Shaft/spline design, fits and tolerances, bearing selection and gearbox stack-up.Planetary Gearset Design Responsibility Architecture selection: single-stage, compound, and double-pinion planetary sets; ratio planning and power flow definition. Perform Macro-geometry calculations for sun/planet/ring (module, teeth numbers, profile shifts) to meet ratio, efficiency and strength targets. Perform Micro-geometry and contact pattern optimization for load sharing across planets, planet phasing strategy and float considerations. Design Carrier (forged/cast) including struts/spiders, pin sizing, retention (press fit/shouldered/snap ring), and stiffness optimization. Design Bearing concepts for planet pins (needle/roller/bronze bush) with L10 life calculations and lubrication paths. Design Ring gear (machined/insert, integral housing ring), spline and bolted interfaces Efficiency modeling, churning loss estimation; lubrication selection (spray/splash/active) and oil flow features. Review and release 3D models and 2D drawings created in NX, ensuring compliance with design standards and Bosch guidelines.
