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:
“To drive Paul out of any lumber camp
All that was needed was to say to him,
“How is the wife, Paul?” and he’d disappear.”
—Robert Frost (1874–1963)
