Abstract
The lead screw assembly uses a traveler nut which includes a second 'nut' screw in meshed contact with the lead screw to transfer the load on the lead screw assembly to thrust bearings. The nut screw is rotational disposed within the nut housing and journaled between a pair of thrust bearings. The orientation of the nut screw to the lead screw and the operative engagement between lead screw and nut screw allows a portion of the load to be transferred to the thrust bearings, thereby reducing the sliding friction of the traveler nut under load. Consequently, the majority of the load is carried by the thrust bearings, which enhances the power efficiency of the lead screw assembly.
