Motorized rotational drive system (8) for rotating a framework about an axis of rotation, preferably a horizontal axis of rotation, for a solar collector tracker support system, said motorized system comprising: two ring gear sectors (80) extending in two planes orthogonal to the axis of rotation and provided with means of attachment to said framework; a transmission shaft (82) supporting two pinions (81) in mesh with the corresponding ring gear sectors (80) for synchronized rotation of said ring gear sectors (80); and a motorized drive means for driving the rotation of said transmission shaft (82). |
