Rack-Pinion / Ball-Screw

See: Add Rack-Pinion

After you add a Rack-Pinion element, you can (optionally) convert it to a Ball-Screw and Nut.

A Pinion is a gear-wheel with teeth that engage with a straight gear, or Rack.

A Ball-Screw is a shaft with threads that engage with a Nut with the same thread.

The motion of the Rack (or Pinion) controls the motion of the Pinion (or Rack).

Or, the motion of the Ball-Screw (or Nut) controls the motion of the Nut (or Ball-Screw).

Use the Rack-Pinion dialog to edit the parameters for the Rack and Pinion (module, number, etc), or a Ball-Screw (Pitch, Diameter, ...).
