20120042741, Feb 23, 2012

Filed:

Feb 15, 2011

Appl. No.:

13/027522

Inventors:

William Vincent Jacob - Chagrin Falls OH, US
Raymond A. Karmansky - North Olmsted OH, US
Nathan Ryan Daniher - Chagrin Falls OH, US

Assignee:

NOOK INDUSTRIES, INC. - Cleveland OH

International Classification:

F16H 57/04
F16H 25/12

US Classification:

74 8944

Abstract:

A mechanical actuator for translating rotational motion to linear motion. The actuator includes a motor, a screw assembly, a bearing assembly, and first and second lubrication systems. The screw assembly includes a housing, a threaded screw shaft disposed within the housing, a nut assembly, and an extension tube. The threaded screw shaft is rotatable by the motor. The nut assembly is arranged to move in either direction along a longitudinal axis of the threaded screw shaft when the threaded screw shaft is in rotational motion, thereby moving the extension tube between an extended position and a retracted position. The bearing assembly is arranged to provide support to at least a portion of a length of the threaded screw shaft. A pathway of the first lubrication system is remote and isolated from a pathway of the second lubrication system.
