Capable of supporting large radial loads due to heavy panels, with a simplified assembly but without compromise in terms of precision and robustness. It comprises an annular structural casing (1), a toothed crown (2) mounted in the structural casing (1), whereon an endless screw (3) actuated by a motor (4) tangentially meshes, the toothed crown (2) of which comprises a central annular protuberance (5) with a toothing that meshes with the endless screw (3), and the circular projections (6) of which of the body of the toothed crown (2) comprise a plurality of threaded holes (7) for connecting the horizontal shafts that support the solar panels for their zenithal orientation, where the toothed crown (2) comprises a toothed track whereon the endless screw (3) tangentially meshes, and two independent raceways. |

1. A zenithal rotation module for orienting solar panels, wherein the panels are intended to be supported by horizontal shafts, the module comprising:
a structural casing having annular configuration; an endless screw; a motor for actuating the endless screw; and a toothed crown mounted inside the structural casing, and having;
an inner cylindrical surface;a central annular protuberance;a toothing, located on the central annular protuberance, and configured so as to tangentially mesh with the endless screw; anda body, comprising:
circular projections with cylindrical surfaces, anda plurality of threaded holes, located on the circular projections, for connecting the horizontal shafts so as to provide zenithal orientation to the solar panels, the zenithal rotation module further comprising:
two circular rings, disposed in opposition on both sides of the central annular protuberance, on the cylindrical surfaces of the circular projections, for fastening the toothed crown inside de structural casing; the circular rings comprising an inner cylindrical surface and an outer lateral surface;a plurality of ball bearings;raceways of semicircular section, for locating the ball bearings, the raceways comprising:
first raceways made in corresponding cylindrical surfaces of the circular projections, andsecond raceways located in the inner cylindrical surface of the circular rings, in correspondence with the first raceways, for establishing four points of contact with the bearings for supporting the radial loads,first ducts made in the body of the toothed crown, said ducts starting in the inner cylindrical surface of the toothed crown and ending in the first and second raceways, for allowing the bearings to be introduced in the first and second raceways, anda plurality of threaded holes located in the outer lateral surfaces of the circular rings for fixing the circular rings to the structural casing. |
