<p>The invention relates to an orientation mechanism with articulated bars and planet gearing, meant for the monoaxial orientation of photovoltaic or solar-thermal platforms, driven by means of a linear actuator, for the purpose of achieving larger angular strokes (> 200°) while avoiding the blocking tendency. According to the invention, the mechanism consists of a plane mechanism with articulated bars, consisting of a base (), a lever (), a connecting rod (), a slider () and a planet gearing whose gear wheels () are articulated to the lever (), a gear wheel () being integral with the connecting rod () and the other gear wheel () being integral with a movable pole () supporting a sun orientation platform, and under the action of a linear actuator () on the slider (), by means of the connecting rod () articulated to the slider (), the gear wheel () induces a large angular stroke to the gear wheel () and implicitly to the platform pole () in conditions of providing a simple construction and of ensuring a minimum allowable transmission angle.</p> |
