FAQ
How does "module" affect gear performance?
Module (metric standard) determines tooth size and load capacity:
Module 0.5-2: Precision instruments (e.g., robotics)
Module 3-6: Automotive transmissions
Module 8-10: Heavy machinery.
Pitch Diameter = Teeth Count × Module.
What are the benefits of hubless designs?
15-25% weight reduction
Simplified shaft mounting
Reduced inertia for high-speed systems (>1000 RPM).
How to minimize operational noise?
Precision grinding (ISO 1328 Class 5-7)
Tooth profile modification (tip relief)
Vibration-damping alloys (e.g., phosphor bronze).
What causes premature gear failure in metal gears?
Pitting: Surface fatigue from overload
Abrasive wear: Contaminated lubricant
Scoring: Insufficient lubrication film thickness.
