Quill Drive

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:

    Certainly, words can be as abusive as any blow. . . . When a three-year-old yells, “You’re so stupid! What a dummy!” it doesn’t carry the same weight as when a mother yells those words to a child. . . . Even if you don’t physically abuse young children, you can still drive them nuts with your words.
    Mary Kay Blakely (20th century)
