ABSTRACT:
A specially constructed drive nut with both threaded and unthreaded axial bores, and a unique resilient mounting assembly therefor, are employed to couple a rotationally driven lead screw to a linearly driven carriage. The mounting assembly includes a specially constructed resilient O-ring which is coaxially positioned on the drive nut near the unthreaded end thereof and, in combination with a pair of adjustable O-ring clamping plates, resiliently mounts the drive nut in a cantilevered manner on an apertured carriage side wall through which the lead screw passes. As constructed and mounted, the drive nut is allowed to become slightly skewed relative to the axis of the lead screw, if required, in order to minimize frictional forces which can develop, for example, because of tolerance variations, bow in the lead screw, or axial misalignment of the latter with the carriage guide rods. By properly selecting the material for the O-ring, any kinetic energy-imparted bounce forces of the carriage may also be substantially, if not completely, absorbed and dissipated in the form of heat.
In an alternative drive nut embodiment, the wall of the threaded portion thereof is segmented so as to form a plurality of resilient, internally threaded fingers for minimizing backlash.
