Home > Quill drive


A quill drive is a mechanism that allows a driven shaft to shift its position (either axially, radially, or both) relative to its driving shaft.

One example of a quill drive is found in a drill press where the quill allows the chuck to move up and down while still being driven. Another example of a quill drive can sometimes be found on a railroad locomotive in the connection between its traction motors and the driven wheels. The GG1 locomotive may be the most famous railroad use of a quill drive.
