Abstract: A gear motor series has two pinions with different numbers of teeth (z1a, z1b), and several toothed wheels with different numbers of teeth (z2a, z3a, z4a). The pinions and the toothed wheels are designed such that each pinion, in several predetermined axial distances (a), can be paired with one of the toothed wheels in order to form a first gear stage. One individual toothed wheel is provided for each predetermined axial distance (a), which is embodied such that it can be optionally paired with the one pinion or with the other pinion to form a first gear stage.

Abstract: A geared motor series includes several motors with different dimensions, which respectively have a motor shaft with a receiving bore on the free end thereof. The nominal outer diameters of the motor shafts of the individual motor dimensions are different from each other. At least one plug-in pinion having a pinion journal is provided with a nominal outer diameter corresponding to the nominal diameter of one of the receiving bores, such that the push-in pinion is fixable to the corresponding motor shaft using a press assembly. The nominal diameter of a receiving bore of a motor shaft of a motor of a first motor dimension corresponds to the nominal diameter of a receiving bore of a motor shaft of a motor of at least one other motor dimension, such that the at least one push-in pinion is fixable to motor shafts of motors having different dimensions using a press assembly.

Abstract: In a two-axle drive system (10) for holding and moving large sunlight-absorbing, concentrating or reflecting surfaces about an azimuth axis (14) and an elevation axis (15), in the case of which a first gear unit which is driven by a first drive (43) is provided for a rotational movement about the azimuth axis (14), and a second gear unit which is driven by a second drive (45) is provided for a rotational movement about the elevation axis (15), the first gear unit being located in a first housing section (23), and the second gear unit being located in a second housing section (24), the first and second housing sections (23, 24) are immobile relative to each other. High stiffness is obtained as a result.
