Excessive Noise and Vibration: The Silent Productivity Killer
Loud grinding or humming from your gearbox? This common symptom often indicates misalignment, improper lubrication, or worn teeth. For procurement specialists, identifying the root cause quickly can prevent cascading failures in production lines.
Problem | Diagnosis | Raydafon Solution |
---|---|---|
High-pitched whining | Incorrect gear meshing | Precision-ground spur gears |
Irregular knocking | Worn bearing surfaces | Hardened alloy steel gears |
Constant humming | Improper lubrication | Self-lubricating gear materials |
Overheating Gears: When Temperatures Rise Too High
Hot gear housings signal efficiency losses that increase energy costs. Our thermal analysis shows 68% of cases stem from excessive friction or overload conditions.

Premature Wear Patterns: Decoding the Damage
Pitting, spalling, or abrasive wear reduce gear life by up to 80%. Raydafon's metallurgists developed proprietary heat treatments that triple surface durability.

Common Gear Problem Questions
Q: How to troubleshoot common gear problems in machinery when lubrication seems adequate?
A: Even with proper lubrication, issues may stem from incorrect viscosity or contamination. Raydafon's lubrication analysis service identifies optimal lubricants for your operating conditions.
Q: What's the first sign of gear tooth failure?
A: Micro-pitting typically appears first, visible under magnification. Our gear inspection packages include microscopic surface analysis to catch issues early.
