  • Linear actuator for large-angle motions
    Patent number: 4565104
    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.
