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:
“Why should I let the toad work
Squat on my life?
Can’t I use my wit as a pitchfork
And drive the brute off?”
—Philip Larkin (1922–1986)
