ABSTRACT:
The invention provides a drive nut bracket for attaching a drive nut to a driven component to move the driven component. The drive nut is moved by a rotating drive screw. The drive nut bracket provides rotational constraint and linear constraint of the drive nut. It has a nut engaging portion pivotally connected to the base. The nut engaging portion has at least one slide surface portion for sliding engagement with the nut so that the nut may slide relative to the nut engaging portion in a direction substantially perpendicular to the pivot axis. The pivot and the slide surface accommodate misalignments of the drive screw and the driven component. The nut engaging portion includes at least one drive force receiving surface portion facing generally along the axis of the drive screw to provide the linear constraint of the drive nut relative to the driven component.
