Gear Weight / Body Optimization
Calculates weight and lightening savings based on outer diameter, face width, bore diameter, and material density.
Gear Weight / Body Optimization
Estimates gear weight from geometry and material density; includes rib/pocketing effect using a lightening factor (typical 0-0.35, maximum 0.6).
Solid (non-lightened) weight14.53 kg
Lightened weight11.62 kg
Savings20.0 %
Volume (solid)0.0019 m3
Applied density7850 kg/m3
Lightening factor0.20
Lightening factor represents removed material ratio via ribs/pockets (0: solid, 0.3: 30% removal). For values above 0.6, run structural analysis. Also verify balancing, welds, or bolt holes for design safety.

Gear Weight OptimizationScope: What does this tool calculate?
Gear Weight Optimization performs the core engineering calculation for this tool type and presents results in a traceable format.
Assumptions and Units
- SI units are the baseline; input unit consistency must be verified by the user.
- The calculation path is deterministic (same inputs = same outputs).
- If default material/environment values are used, replace them with project-specific values.
Limits / Boundaries
- This tool is intended for preliminary sizing and technical checks, not final design approval.
- When inputs are outside expected ranges, validate input quality before interpreting outputs.
Reference Standard
- ISO / DIN / VDI references and common engineering handbooks
Validation Example
Validation example
| Input | Expected Output |
|---|---|
| Input set: Unit-consistent project values | Expected output: Tool result is in the same order as standard references |
Note: In real projects, run at least one manual check or reference-table comparison.
