Linear Actuator For Large-Angle Motions
US Patent:
4565104, Jan 21, 1986
Filed:
Sep 20, 1982
Appl. No.:
6/420033
Inventors:
Thomas A. Akin - Smyrna GA
Assignee:
Scientific-Atlanta, Inc. - Atlanta GA
International Classification:
F16H 2702, F16H 2902, F16H 2920, F16H 2145
US Classification:
74 8915
Abstract:
A linear actuator for rotating a load, such as an antenna, in which the load is pivoted about a load pivot axis and a drive point on an arm extending from the load is driven along a path of travel defined by a frame pivoted about a frame pivot axis parallel to the load pivot axis and normal to the path of travel, the load pivot axis being equally distant from the drive point and the frame pivot axis. The structure of the linear actuator reduces loss of moment arm at the extremes of travel and minimizes stress on the components of the actuator.
