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:
“Ha, ha, my ship! thou mightiest well be taken now for the sea- chariot of the sun. Ho, ho! all ye nations before my prow, I bring the sun to ye! Yoke on the further billows ... I drive the sea!”
—Herman Melville (1819–1891)
