A quill drive is a mechanism that allows a drive shaft to shift its position (either axially, radially, or both) relative to its driving shaft. It consists of a hollow driving shaft (the quill) with a driven shaft inside it. The two are connected in some fashion which permits the required motion.
Famous quotes containing the word drive:
“Who will go drive with Fergus now,
And pierce the deep wood’s woven shade,
And dance upon the level shore?”
—William Butler Yeats (1865–1939)
