The prompt
Create a parametric helical bevel gear pair with a 90-degree shaft angle. Module m = 1 mm, pressure angle α = 20°, helix angle β = 35°. Pinion (driver): 8 teeth (z₁ = 8), right-hand helix, face width 8 mm, center bore 5 mm. Gear (driven): 16 teeth (z₂ = 16), left-hand helix, face width 8 mm, center bore 8 mm. Generate precise pitch cones, back cones, and involute tooth profiles. Output as a manufacturing-ready STEP file
Parameters
| Name | Value | Range |
|---|---|---|
| Module | 1 mm | 0.5 – 3 |
| Pinion teeth (z1) | 8 count | 5 – 30 |
| Gear teeth (z2) | 16 count | 8 – 60 |
| Pressure angle | 20 deg | 14.5 – 25 |
| Helix angle | 35 deg | 0 – 45 |
| Face width | 8 mm | 2 – 20 |
| Pinion bore | 5 mm | 2 – 20 |
| Gear bore | 8 mm | 2 – 30 |
| Mesh overlap (union allowance) | 0.15 mm | 0 – 0.5 |
