Product Description

Common Failure Modes	Relevance to the Role of Planetary Gears	Design Solutions
Tooth Surface Fatigue Pitting	Excessive contact stress causing surface spalling	Increase the number of planetary gears and optimize tooth surface roughness (Ra≤0.4μm)
Fracture of Planetary Shaft	Impact load exceeding material strength limit	Adopt high-strength alloy steel (e.g., 20CrNi2Mo) and increase shaft diameter safety factor
Seizure due to Lubrication Failure	High heat generation from multi-tooth meshing and insufficient lubrication	Design a forced lubrication system (oil temperature controlled ≤80ºC) and use extreme pressure gear oil
