🔍 Key Concepts

• Location and function of a rotating seal in a reversing reduction gear • How lube oil is contained around roller bearings on a high‑speed shaft • Typical ways tachometers and operating air are connected to machinery

💭 Think About

• Look closely at where the seal is placed in relation to the output shaft and gear case. What needs to be kept in or out at that point? • Which of the listed functions would logically require a rotating, shaft-mounted seal instead of piping or mechanical linkage? • If lube oil is splashing inside the gear case, what prevents it from escaping along the shaft through the bearings?

✅ Before You Answer

• Confirm which component in the illustration actually rotates with the shaft and where the seal contacts the housing • Check whether there are any oil passages or air pipes leading directly to that rotating seal location • Decide which option best matches a seal’s normal duty: retaining fluid, transmitting motion, or supplying pressure
