Ratio, lead angle, efficiency, locking hint.
Gear ratio G = Ng / Nw (starts). Lead L = Nw·Px, lead angle γ = atan(L / (πDw)). Static efficiency η ≈ tan γ / tan(γ + φ); self-locking is plausible when γ < φ (simplified check).
- Ratio G20
- Lead L12.56 mm
- Lead angle γ11.3043°
- Static efficiency η0.6416
- Self-locking (γ < φ)Unlikely
