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:
“We do not want them to have less.
But it is only natural that we should think we have not enough.
We drive on, we drive on.
When we speak to each other our voices are a little gruff.”
—Gwendolyn Brooks (b. 1917)
