Q

Wear occurring at the tips of the reduction gear teeth is usually the result of __________.

🔍 Key Concepts

• gear tooth contact pattern along the face of the tooth (root, pitch line, and tip) • how misalignment changes where the tooth load is carried • difference between fatigue/pitting in the middle of the tooth vs. wear concentrated at ends or tips

💭 Think About

• Think about what would cause the tips of the gear teeth to carry more load than the rest of the tooth surface. • Which condition would change the way the teeth mesh and shift the contact pattern toward the ends rather than evenly across the whole face? • Which options usually cause damage near the pitch line or whole surface, and which one would localize damage to just the tips?

✅ Before You Answer

• Identify which choices are typically associated with pitting and spalling over the whole working surface, not just the tips. • Consider which condition would result from poor alignment of shafts, bearings, or housings, changing the way the teeth meet. • Eliminate any answer that normally produces damage mainly at the pitch line or root instead of the tips.
