Abstract
An actuator (10) for effecting relative pivotal movement between two structures (12, 14) includes a bent beam member (18) having a first portion (20) rotatably secured to one structure and a second portion (22) supported for rotation and eccentric revolution by a housing (42) grounded to the other structure. Index gears (64, 66) assure eccentric revolution of the beam member (18) in an opposite direction in response to rotation of the bent beam member to produce relative pivotal movement between the beam members (20, 22). In the first two embodiments, the actuators (10, 120) incorporate internal hydraulic or electric drive arrangements. In other embodiments, the actuators (150, 172, 250, 270) employ various planetary type gear arrangements to achieve even greater mechanical advantage. In the last embodiment, both portions (304, 306) of the bent beam member (302) of the actuator (300) are driven and supported for eccentric revolution.
