Abstract: A solar tracker having at least one post (7) for fixing to the ground at least one solar panel (8) that rotates by action of a drive, which has a rotation transmission support (1) on which the solar panel (8) is supported and which is coupled to the post (7) in such a way that it slides along a horizontal guide rail (2) fixed to the post (7) by a guide element (3), and the rotation transmission support (1) rolling on a rolling contact element (4) fixed to the post (7) to establish the rotation of the solar panel (8) in both directions.

Abstract: A bearing for fastening rotating shafts on support posts is provided, having a support (1) by which a clamp (3) is fastened on the support post (2), incorporating in the clamp (3) a ball joint (4.1) through which the rotating shaft (5) to be fastened passes, wherein the support (1) is made up of two complementary portions, which are axially attached facing one another, retaining the support post (2) between them, whereas on the assembly of the mentioned support (1) there is fixed a clamp (3) which houses internally a spherical ball joint (4.1) which determines a central opening through which the rotating shaft (5) to be fastened passes.

Abstract: A bearing (1) for rotational shafts supported by support pillars, to establish the fastening between a rotational shaft (3) and support pillars (2), able to rotate freely, having a support (4) which is fixed to the support pillar (2), the support (4) being axially clamped between two component parts (6.1), (6.2) of a clamp (6), which determines a ring (7) that houses a ball joint (5), through which the rotational shaft (3) being fastened is arranged.

Abstract: A plurality of posts and actuator posts connected to a foundation and to a torque tube on which solar panels are duly mounted is disclosed. The actuator posts include a hinge next to a radial arm that is disposed solidly connected to the torque tube, the arm being hinged at the other end to a linear actuator with screw drive, the bottom end is connected to the actuator post by a joint. Each linear actuator is actuated by a gear that engages with an endless screw solidly connected to a Cardan-type drive shared by all the actuators and is actuated by an electric motor, the Cardan-type drive fitting closely to the torque tube by supports.
