- Quill drive
A quill drive is a mechanism that allows a
drive shaft to shift its position (eitheraxial ly,radial ly, or both) relative to itsdriving shaft . It consists of a hollow driving shaft (thequill ) with a driven shaft inside it. The two are connected in some fashion which permits the required motion.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.Quill drives have been extensively used in railroad
electric locomotive s to connect between thetraction motor s and the driven wheels. The two are linked by a flexible drive which allows a degree of radial motion and possibly a small amount of axial motion. This smooths the drive from the motors and isolates them from mechanical shock as well. Quill drives were used by many electric locomotives in theUnited States , particularly those of thePennsylvania Railroad —their long-lasting GG1 design being perhaps the best known. Many locomotives built inFrance ,Germany andItaly used quill drives as well, allowing higher locomotive speed.ee also
