ABSTRACT:
An apparatus for converting rotary motion to translatory motion. The apparatus contains shaped rollers located therein so that the longitudinal axis of the rollers forms an acute angle with the longitudinal axis of a shaft passing through the apparatus. The rollers are contained in a cylindrical housing having end pieces. The rollers are shaped to have maximum contact with the shaft. Roller race means and spring means contained within the housing retain the rollers and provide a load to maintain tight shaft to roller contact. Rotation of the apparatus about a shaft causes a shaft to move in a longitudinal direction, while rotation of the shaft within the apparatus causes the apparatus to move in a longitudinal direction.
