🔍 Key Concepts

• Reduction gear lubrication and why a continuous oil film is important between metal surfaces • What scoring looks like on gear teeth (scratches, gouges, metal-to-metal contact) • Difference between wear from contact and damage from corrosion or fatigue

💭 Think About

• Which option would most directly allow metal gear tooth surfaces to rub or scrape against each other under heavy load? • Which process depends on repeated cyclic loading over long periods, and which depends more on loss of separation between metal surfaces? • How would the presence or absence of contamination (like water) change the type of damage you see on the teeth?

✅ Before You Answer

• Identify which choice describes a loss of separation between moving metal surfaces. • Separate in your mind: corrosion-related damage vs. mechanical contact damage. • Ask: Which option is most clearly associated with scratches/galling from metal-to-metal contact rather than pitting or rust-like damage?
