Latest Patents

James E. Black holds a patent for a "Ball screw drive with dynamically adjustable preload." This invention features a threaded ball screw that is stationarily non-rotatably mounted in a machine tool, extending parallel to the line of action traversed by a carriage. The design includes a pair of threaded ball nuts that are laterally restrained and mounted for free rotation within the drive mechanism of the carriage. These nuts threadably and concentrically engage the ball screw in a laterally spaced apart co-axial relationship. The system incorporates digitally controlled electric drive motors that individually impart rotational torque to the nuts, allowing for precise control of linear motion and positioning of the carriage along the stationary ball screw.
