What potentially dangerous condition might result from improper lubrication of gear couplings?

• A. Corrosion of metals
• B. Excessive friction leading to heat
• C. Increase in gear noise
• D. Improved gear efficiency

Answer: (B)

Improper lubrication of gear couplings can lead to excessive friction, which results in increased heat generation during operation. When lubrication is inadequate, metal parts rub against each other without the protective film that oil provides. This friction generates heat, which can elevate temperatures to levels that may damage components, reduce the lifespan of the gear couplings, and potentially lead to catastrophic failure if not addressed. Ensuring proper lubrication helps maintain smooth operation, minimizes wear and tear, and prevents overheating, making it essential for safety and equipment longevity. The other conditions listed, while potentially related to lubrication issues, do not directly represent the most immediate and dangerous consequence. For instance, corrosion requires moisture and may occur over a longer timeframe, while an increase in gear noise could indicate issues but isn't necessarily linked to a hazardous situation in the same way that excessive heat is. Improved gear efficiency, on the other hand, is a desired outcome and not a potential danger.
