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, outlaws on God’s property,
Fling out imagination beyond the skies,
Wishing a tangible good from the unknown.
And likewise death will drive us from the scene
With the great flowering world unbroken yet,
Which we held in idea, a little handful.”
—Richard Eberhart (b. 1904)
