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:
“They shoulda called me Little Cocaine, I was sniffing so much of the stuff! My nose got big enough to back a diesel truck in, unload it, and drive it right out again.”
—Little Richard (b. 1932)
