Q

The function of a quill shaft used on a double reduction gear main propulsion unit is to __________.

🔍 Key Concepts

• Quill shaft design and where it is installed in a double-reduction gear train • Difference between radial misalignment, axial movement, and torsional (twisting) flexibility • How power is transmitted from the high‑speed pinion to the first reduction gear and then to the second reduction

💭 Think About

• Think about what kind of movement or flexibility a long, slender shaft is best at handling: sideways (radial), end‑to‑end (axial), or twisting (torsional). • Ask yourself: in a double‑reduction gear, where is vibration and shock most severe—on the high‑speed side or the low‑speed side? How would a quill shaft help with that? • Consider which pair of gears the quill shaft actually connects in most common marine double‑reduction arrangements.

✅ Before You Answer

• Identify between which two components the quill shaft is normally installed in a double reduction unit. • Decide whether the main purpose is to correct misalignment, to control backlash, or to provide flexibility (and what kind). • Check which answer choice correctly matches the location of the quill shaft with the type of flexibility it provides.
