Question 1 of 27070

When passing through mesh contact, the teeth of a reduction gear first go through a series of actions best described as __________.

🔍 Key Concepts

• Gear tooth contact pattern during engagement • Difference between sliding vs rolling action in gear meshes • How reduction gears share load when speed changes from high to low

💭 Think About

• Think about what happens exactly at the first instant when two gear teeth touch—are they mainly rolling on each other or is there relative motion along the tooth surface? • In a reduction gear, the smaller pinion drives a larger gear. How does that affect the type of contact between the tooth faces as they move through the mesh? • Which term describes a normal, designed action of the tooth surfaces, and which ones sound like damage or malfunction conditions?

✅ Before You Answer

• Identify which of the options refers to a normal, intended motion between gear teeth, not a failure mode • Recall that high-pressure areas at first contact involve both compression (normal force) and tangential motion along the tooth face • Eliminate any choices that describe permanent damage or abnormal wear rather than a standard phase of tooth engagement
