Notes for Technical Terms
- Helix Angle (β): The angle between the tooth helix and the gear axis; higher angles improve smoothness but increase axial force.
- Backlash: The clearance between non-working tooth surfaces; critical for precision applications (e.g., robotics ≤ 0.05mm).
- AGMA/ISO Grades: AGMA 10-12 (high precision), ISO 6-8 (industrial standard).
