ABSTRACT:
An electromechanical linear actuator assembly having in-line axial load support of its screw drive shaft is provided. The bearing support structure provides a single in-line ball bearing accommodated within a hardened end fitting and a screw pivot recess in the axial screw drive shaft. For axial loading in an opposite direction, a number of smaller ball bearings are provided around the outer periphery of the screw shaft in a groove, and are retained within the hardened end fitting by a bearing retainer. End rod support bearings providing heat compensation and lubrication fluid transfer are also provided. A braking mechanism having increased life and more consistent load engagement is also provided. Further, integrated electronics may be provided for position sensing and power efficiency control.
