The invention relates to a tracking device comprising a receiving structure that can be adjusted about at least one axis, for mounting at least one element that is sensitive to electromagnetic waves and has a preferential radiation direction, and comprising at least one rotational drive per axis for the purpose of actively rotationally adjusting said receiving structure in order for the element(s) mounted thereupon to track a celestial body on one or multiple axes with the aid of a control system and according to a predetermined algorithm, (each of) the rotational drive(s) comprising two annular connection elements that are concentric with one another, are mounted one upon the other, and are or can be coupled to at least one motor for mutual relative adjustment, a first connection element comprising at least one planar connection surface for fixing in place to a foundation, base, column or a connection clement of another pivoting unit, and a second connection element comprising at least one planar connection surface for the purpose of coupling to said receiving structure or to a connection element of another pivoting unit in a rotationally-fixed manner. In addition, at least one row of roller elements is provided between the concentric annular connection elements of a pivoting unit, said roller elements rolling along raceways on the first and second connection elements, a toothing being provided that extends at least partially around one connection element and is formed, together with the raceway(s) that are in place, by machining or shaping a shared annular main part, and bore holes distributed in a circle and passing through the planar contact surface being provided on the other connection element for the purpose of fixing to a contact part, and being formed together with the raceway(s) that are in place by machining or shaping a shared annular main part. |
