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:
“I am every day more convinced that we women, if we are to be good women, feminine and amiable and domestic, are not fitted to reign; at least it is contre gré that they drive themselves to the work which it entails.”
—Victoria (1819–1901)
