<p>An apparatus for producing linear motion from rotary motion is disclosed comprising a drive rod (10) of circular cross section which is arranged to be rotated at a constant speed in the same direction. A carriage (11) which is arranged to be mounted on the rod for axial movement along the length thereof is provided with at least one roller member (12a, 12b) arranged to engage the rod at an angle to the axis of rotation of the rod. The rotary motion of the red then causes the roller member to rotate, thereby generating an axial rector component in a direction along the rod, thus causing the carriage to move in a linear direction along the rod.</p> |
