Pitting in the area close to the pitch line and on the same end of each gear tooth of a reduction gear unit would be caused by __________.

🔍 Key Concepts

• reduction gear tooth loading along the pitch line • difference between corrosion/pitting versus mechanical contact damage • effects of gear alignment and lubrication on the contact pattern

💭 Think About

• Think about what would make damage appear in the same location on every tooth, on the same end, near the pitch line. What does that say about how the gears are contacting each other? • Which of these choices would cause random, scattered damage versus a consistent, repeated pattern on each tooth? • How would the direction of load transfer between mating gears change if the shafts or bearings were not perfectly aligned?

✅ Before You Answer

• Is the damage pattern uniform on the same end of each tooth (suggesting a systematic mechanical issue) or random (suggesting contamination or corrosion)? • Would dirt in the oil or corrosion likely affect just one end of every tooth, or would it be more widespread and irregular? • Does gear speed alone create localized pitting on just one end of the teeth, or does that symptom point more toward how the teeth mesh together?
