Definitions
- the present invention relates to a drive arrangement for driving at least one output unit.
- Such drive arrangements have a transmission element and an output unit.
- the transmission element is brought into engagement with the output unit in order to transmit a torque or a force to the output unit.
- Such drive arrangements are often referred to as Geneva drives or "Geneva drives”.
- the drive arrangement according to the invention for driving at least one displaceable output unit comprises at least one transmission element which can be rotated about an axis of rotation and has at least one drive element and at least one holding element.
- the at least one drive element is offset in the radial direction to the at least one holding element.
- the drive arrangement also includes at least one output unit, the output unit having at least one drive recess and at least one holding recess.
- the at least one drive element is associated with the at least one drive recess and engages in the at least one drive recess to drive the output unit.
- the at least one holding element is assigned to the at least one holding recess and engages in the at least one holding recess to hold the output unit in a set position.
- the at least one drive cavity has an entry opening, an end region and a middle region formed between the entry opening and the end region, the at least one driving cavity having a reduced cross-section in the middle region compared to the end region.
- the at least one transmission element and the output unit are designed in such a way that the function of the drive arrangement can be permanently guaranteed.
- the force-transmitting or torque-transmitting engagement between the at least one drive recess and the at least one drive element can be ensured even if the distance increases due to manufacturing tolerances, assembly tolerances and/or elastic deformations of the at least one transmission element and/or the at least one output unit between the at least one transmission element and the at least one output unit.
- the cross-section of the at least one drive recess can be larger at the entry opening than in the central area of the at least one drive recess.
- the at least one drive recess can have opposing wall sections.
- the opposite wall sections can have a curvature. Due to their curvature, the opposite wall sections can reduce the cross section of the at least one drive recess in the central area.
- the opposite wall sections can each have an apex.
- the opposite wall sections can have the smallest distance from one another at the crests.
- the distance between the opposite wall sections can reduce starting from the entrance opening to the crests.
- the distance between the opposing wall sections can increase starting from the apexes in the direction of the end region of the at least one drive recess.
- the end area of the at least one drive recess can comprise a base of the drive recess or be formed by a base of the drive recess.
- the at least one drive recess designed in this way contributes to the fact that a larger permissible play can be achieved between the output unit and the at least one transmission element in order to be able to compensate for assembly tolerances and manufacturing tolerances.
- a relative movement between the output unit and the at least one transmission element can be blocked longer by the at least one drive element, so that a premature release of the output unit due to a Movement of the output unit can be prevented under load.
- undesired movements of the drive unit can be reliably prevented.
- the at least one drive element can have a longitudinal axis.
- the at least one drive element can have a cross section that is curved at least in sections and differs from a circular cross section.
- the longitudinal axis can extend at least essentially parallel to the axis of rotation of the at least one transmission element.
- the cross section of the at least one drive element can have a radial distance from the axis of rotation. The axis of rotation can thus lie outside the cross section of the at least one drive element in the radial direction.
- the at least one transmission element and the output unit are coupled in a force-transmitting or torque-transmitting manner such that when the at least one transmission element executes a rotary movement, the output unit is adjusted step by step.
- a continuous rotational movement of the at least one transmission element about the axis of rotation accordingly leads to a gradual adjustment movement of the output unit.
- the adjustment movement of the output unit is always carried out when the at least one drive element is in engagement with the at least one drive recess.
- the at least one transmission element rotates, the at least one drive element can engage in the associated drive recess of the output unit, take the output unit with it and then leave the drive recess again.
- the at least one drive element presses against a wall of the drive recess, as a result of which a force or torque is exerted on the output unit, which leads to an adjustment movement of the output unit by one step.
- the at least one holding element always engages in the at least one holding recess of the output unit when the at least one drive element is not in engagement with the at least one drive recess of the output unit.
- the at least one holding element can engage in the at least one holding recess in a form-fitting manner. In this state, the output unit can be held in its set position. The Drive assembly is thus in a locked position. In the locked position, movement of the output unit is prevented.
- a section of the at least one holding element initially engages in the at least one associated holding recess of the output unit, with this section continuously increasing up to a maximum overlap due to the rotary movement of the at least one transmission element, before the superimposition decreases again with a continued rotational movement of the at least one transmission element in the same direction of rotation.
- the holding element can leave the at least one holding recess again. As soon as the at least one holding element engages even only partially in the holding recess, movement of the driven unit can be prevented.
- the holding element and the drive element rotate further or backwards so that the drive element can be brought into engagement with the next drive recess.
- the drive element can be rotated about the axis of rotation of the at least one transmission element in order to engage in the next drive recess.
- the at least one retaining element continues to rotate in the retaining recess and leaves the retaining recess when or shortly after the drive element engages the next drive recess. The at least one holding element thus releases the driven unit for the next adjustment step.
- the at least one drive element can have a cross section with at least one curved section that contacts a wall of the at least one drive recess for driving the at least one output unit.
- the at least one drive element can have a reduced cross section in the radial direction in relation to the axis of rotation of the at least one transmission element.
- the cross section of the at least one drive member may have at least one first apex and at least one second apex. The distance between the first apex and the second apex may define the greatest extent of the drive member.
- the cross section of the at least one drive element can have its greatest extent in a direction transverse to the have radial direction of the at least one transmission element.
- the cross section of the at least one drive element can have at least one first edge and at least one second edge, the distance between which defines the greatest extent of the drive element. If two edges are provided on the cross section of the drive member, the cross section of the drive member may have two curved portions extending between the two edges.
- the cross section of the drive element has two vertices
- the cross section is also curved in the region of the vertices.
- the cross section of the drive element can thus have several radii of curvature.
- the radius of curvature in the region of the vertices may differ from the radius of curvature of the section between the two vertices.
- the at least one drive element can be made larger or wider in the tangential direction, i. H. the distance between the first apex and the second apex of the driving element can be correspondingly greater.
- the at least one drive element can accordingly absorb greater forces and be more robust overall.
- the cross section of the at least one drive element may have at least one third vertex and at least one fourth vertex.
- the distance between the third vertex and the fourth vertex may be less than the distance between the first vertex or edge and the second vertex or edge.
- the third apex and the fourth apex can be aligned in the radial direction of the at least one transmission element.
- the distance between the first apex and the second apex may be tailored to the size of the drive cavity. Due to the reduced cross section of the drive element in the radial direction, the drive recesses in particular can be designed with a reduced cross section at the inlet opening, since the at least one drive element requires only little space due to its shape in order to be able to dip into the corresponding drive recess.
- the size of a radial free space between the at least one holding element and the at least one drive element can be determined, among other things, via the distance between the third or the fourth apex, i.e. via the cross section of the drive element that is reduced in the radial direction, which is necessary for the alternating engagement of the drive element and of the retaining element can support in the respectively associated drive recess and retaining recess.
- the at least one drive recess can widen in the direction of its entry opening. By widening the drive recess to the outside, the entry opening of the drive recess for the penetration or engagement of the drive element can be enlarged.
- the distance between two opposite wall sections of the at least one drive recess can increase in the direction of the inlet opening.
- the axis of rotation of the at least one transmission element can run through or along the at least one holding element.
- the at least one holding element can have an outer contour with a curvature.
- the curvature of the outer contour of the retaining element is matched to the curvature of the at least one retaining recess, so that the at least one retaining element can penetrate into the at least one retaining recess and rotate in the retaining recess. As soon as the at least one holding element penetrates into the at least one holding recess, a movement of the output unit can be blocked.
- the radius of curvature of the curved outer contour can be matched to the radius of curvature of the wall of the at least one holding recess.
- the at least one holding member may have a curved surface facing the at least one drive member.
- the curved surface can be concavely curved.
- the at least one drive element and the at least one holding element can be connected to one another via at least one contact section.
- the contact section can extend in the radial direction.
- the contact section can, for example, be disc-shaped or cam-shaped.
- the at least one contact section can also be connected to at least one coupling section be, via which the at least one transmission element can be coupled to at least one drive shaft.
- the coupling to the drive can take place directly or indirectly via other components.
- the at least one drive element and the at least one holding element can extend parallel to the axis of rotation of the at least one transmission element.
- the drive recesses and the holding recesses can be designed to correspond to the shape or the cross section of the drive element and the holding element.
- the at least one drive element can have an oval or elliptical or lenticular or circular cross-section.
- the at least one holding element can have a cross section in the shape of a segment of a circle or a crescent.
- the at least one output unit can be a unit that can be rotated or pivoted about an axis.
- the drive recesses and the holding recesses can be formed on the inner circumference or on the outer circumference of the output unit that can be rotated or pivoted about an axis.
- the at least one output unit can be a linearly displaceable unit.
- the drive recesses and holding recesses of the linearly displaceable output unit can be arranged along the movement axis.
- the linearly displaceable output unit can be a toothed rack, for example.

- the sleeve 70 has a radially inwardly projecting collar at its respective other axial end, with which the sleeve 70 can be supported on the end face of the coupling section 62 .
- the sleeve 70 is used to compensate for angular offsets between the drive shaft piece 28a and the transmission element 38.
- the tubular coupling section 64 and the drive shaft piece 28b are coupled to one another via the bolt 58 in a torque-transmitting manner.
- the bolt 58 extends perpendicularly to the axis of rotation DA through the coupling section 64 and the drive shaft piece 28b.
- An elastic element 72 in the form of a sleeve is arranged in the radial direction between the tubular coupling section 62 and the drive shaft piece 28b.
- the sleeve 72 is identical to the sleeve 70 described above.
- the sleeve 72 surrounds the end section of the coupling section 64 and is supported on the end face of the drive shaft piece 28b via a collar that protrudes radially outward.
- the sleeve 72 has a radially inwardly projecting collar at its respective other axial end, with which the sleeve 72 can be supported on the end face of the coupling section 64 .
- the sleeve 72 is used to compensate for angular offsets between the transmission element 38 and the drive shaft piece 28b.
- FIG. 11 shows a further enlarged detail from FIG. 8.
- the drive unit 26 is coupled to the drive shaft 28 or to the drive shaft piece 28a at the coupling point KS1 via the output element 54 and the bolt 56 .
- the axis of rotation DE of the motor 30 and the axis of rotation DA, in which the axis of rotation of the drive shaft piece 28a, the axis of rotation of the output element 54 and the axis of rotation of the transmission element 38 coincide, extend at least essentially parallel to one another.
- FIG 12 shows a view of the transmission element 38.
- the transmission element 38 comprises the two coupling sections 62 and 64 as well as the engagement section 66 arranged in the axial direction between the coupling sections 62 and 64.
- the coupling sections 60 and 62 each have a section 74 and 76 an increased diameter.
- the sections 74 and 76 each form a bearing section 74, 76, with which the transmission element 38 can be mounted on the bearing elements 36 (see, for example, FIG. 8).
- Each coupling section 62 and 64 has a groove 78 and 80 which extends from the end face of the respective coupling section 62, 64 in the axial direction into the respective coupling section 62, 64.
- the grooves 78 and 80 serve to prevent the sleeves 70 and 72 from rotating, which are slipped onto the ends of the coupling sections 62 and 64 before the respective coupling sections 62, 64 are inserted into the end of the corresponding drive shaft piece 28a or 28b (see FIG. 10).
- the sleeves 70 and 72 can have projections (see FIG. 10) on their radially inwardly projecting collars which engage in the grooves 78 and 80 in order to prevent the sleeves 70 and 72 from twisting.
- the engagement section 66 is delimited by two contact sections 82 and 84 .
- the contact sections 82 and 84 can be supported on the bearing elements 36 in the axial direction.
- the contact sections 82 and 84 have the largest diameter of the transmission element 38 .
- the abutment portions 82 and 84 form a guide for the drive arc 18 (see Figure 10).
- the drive arch 18 runs between the two contact sections 82 and 84 or between the opposing side faces of the contact sections 82 and 84 (see FIG. 10).
- the engaging portion 66 includes a driving member 86 and a holding member 88 .
- the drive element 86 is arranged at a distance from the holding element 88 in the radial direction in relation to the axis of rotation DUE.
- the drive element 86 is designed to engage in one of the drive recesses 40 of the drive arc 18 .
- the holding element 88 is designed to engage in a holding recess 42 in the drive bow 18 .
- FIG. 13 shows a view of the end face of the coupling section 64 of the transmission element 38.
- the coupling section 64 is tubular.
- the grooves 80 extend in the axial direction, starting from the end face of the coupling section 64 and into the coupling section 64 .
- the contact section 84 with its larger diameter forms the end of the coupling section 64. This also applies analogously to the coupling section 62, which is shown in FIG.
- Figure 14 shows a sectional view along line XIV-XIV in Figure 12.
- the drive element 86 In relation to the axis of rotation DUE, the drive element 86 is in the radial direction arranged at a distance from the holding element 88 . There is thus a radial free space between the drive element 86 and the holding element 88 .
- the axis of rotation DUE runs at a radial distance from the holding element 88.
- the drive element 86 is therefore arranged eccentrically, unlike the holding element 88.
- the drive element 86 is cylindrical (see Figures 12 and 14).
- the drive element 86 has a cross section that deviates from a circular cross section and is curved at least in sections.
- the cross section of the drive element 86 is reduced in the radial direction relative to its longitudinal axis L compared to a circular cross section.
- the cross section of the drive element 86 can be described as oval, lenticular or else elliptical. Due to the cross section of the drive element 86 that is reduced in the radial direction, the engagement of the drive element 86 in one of the drive recesses 40 can be ensured, so that the function of the drive of the swivel unit 16 can be permanently guaranteed.
- the cross-section of drive member 86 has four vertices Si, S 2 , S 3 and S 4 .
- the drive element 86 has its greatest extension in a direction transverse to the radial direction, ie in the tangential direction, between the vertices Si and S 2 .
- the distance between vertices Si and S 2 defines the greatest extent of drive element 86 .
- the vertices S 3 and S 4 are aligned in the radial direction. The distance between vertices S 3 and S 4 is smaller than the distance between vertices Si and S 2 .
- the longitudinal axis L of the drive element 86 extends parallel to, but offset in the radial direction, the axis of rotation DUE of the transmission element 38.
- the holding element 88 has an outer contour 90 in the form of an arc of a circle.
- the surface 92 of the holding element 88 facing the drive element 86 is curved.
- Surface 92 may be concavely curved.
- the cross section of the holding element 88 can be referred to as crescent-shaped.
- the axis of rotation DUE can extend through the center point of the arcuate outer contour 90 of the holding element 88 . Due to the concave curvature of the surface 92, the axis of rotation DUE does not extend through the cross section of the holding element 88 but along the surface 92.
- FIGS. 15a and 15b show views of the drive arch 18.
- the drive arch 18 has attachment openings 94 and 96 with which the drive arch 18 can be attached to the cross member 20 (see FIG. 3).
- the attachment openings 94 and 96 are configured to allow the drive bow 18 to be attached to the cross member 20 in various positions.
- the fastening openings 94 and 96 are in the form of elongated holes and are composed of three partial openings. Each of the partial openings defines a position in which the drive arch 18 can be attached to the cross member 20 . Mounting tolerances can be compensated for by the fastening openings 94 and 96 designed in this way.
- the drive arch 18 also has the drive recesses 40 and the retaining recesses 42 .
- the drive recesses 40 and the holding recesses 42 are arranged alternately in the circumferential direction of the drive arc 18 .
- the driving recesses 40 and the holding recesses 42 are provided on the outer circumference of the driving arc 18 .
- FIG. 15b shows an enlarged detail from FIG. 15a.
- the drive recesses 40 extend further in the radial direction than the retaining recess 42 into the drive arc 18 .
- the drive recesses 40 change their cross section in the radial direction. Starting from the inlet opening 98, the cross section of the drive recess 40 initially narrows. The cross section of the drive recess 40 widens again in the direction of the radial end region or the base 100 .
- the drive recesses 40 have opposing wall sections 102 and 104 .
- the wall sections 102 and 104 are curved.
- the curvature of the wall sections 102 and 104 reduces the cross section of the drive recess 40 in the middle area in the radial direction.
- wall sections 102 and 104 each have an apex S 5 and S 6 .
- the two opposite wall sections 102 and 104 of the drive recess 40 reduce their distance A from one another up to their respective apex S 5 and S 6 .
- the two wall sections 102 and 104 are at the smallest distance A from one another at the vertices S 5 and S 6 .
- the distance A between the two opposite wall sections 102 and 104 increases again in the direction of the radial end area or the base 100 of the drive recess 40.
- the drive recesses 40 are therefore designed with an undercut.
- the curvature of the two opposite wall sections 102 and 104 represents a convex curvature.
- FIGS. 16a, 17a and 18a The function of the pivoting unit 10 of FIGS. 16a to 18b is explained below.
- the driving arc 18 and the transmission element 38 are shown in FIGS. 16a, 17a and 18a.
- the transmission element 38 has a different rotational position.
- the drive arc 18 is moved to the “left” due to the rotary movement of the transmission element 38.
- the changing rotational position of the transmission element 38 can be seen from the different positions of the grooves 80 .
- FIGS. 16b, 17b and 18b show the sections marked accordingly in FIGS. 16a, 17a and 18a in an enlarged form.
- FIGS. 16a and 16b show a state of the drive arch 18 and the transmission element 38 in which the holding element 88 of the transmission element 38 engages in a holding recess 42 in the drive arch 18.
- the engagement of the holding element 88 in the holding recess 42 determines the set position of the drive arch 18 or the drive arch 18 is locked in the set position, ie. H. held in the locked position.
- the pivoting units 16 can be held securely in the set pivoting position even in the case of relatively strong external influences such as strong winds, without significant torques having to be transmitted to the drive system.
- FIGS. 17a and 17b the transmission element 38 was further driven.
- the rotational position of the holding element 88 in the holding recess 42 has been changed.
- the drive element 86 is located at the entry opening 96 of the drive recess 40 formed on the right next to the retaining recess 42 in Figure 17b.
- the drive arc 18 cannot yet be moved, since the retaining element 88 is still flat on the wall of the Retaining recess 42 is present.
- the drive element 86 acts on a wall section 102 of the drive recess 40 and moves the drive arch 18 further as a result of contact with the drive arch 18 .
- the drive unit 26, the drive shaft 28 and the at least one transmission element 38 can be coupled to one another in a torque-transmitting manner at a single axial coupling point KS1.
- KS1 a simple and compact construction of the drive of the tracking device 10 can be achieved.
- the axial coupling point KS1 means that little time is required to connect or disconnect the individual components during assembly or maintenance work.
- the functionality of the drive of the tracking device 10 can be permanently ensured by the drive recesses 40 and the retaining recesses 42 on the drive arc 18, which interact with the transmission element 38.

- FIG. 22 and 23 show perspective views of the tracking device 10.
- the hanger 106 is attached to the cross member 108 and supports the drive shaft sections 28a and 28b at the connection point VS.
- the hanger 106 hangs down from the cross member 108 .
- the suspension 106 has the connection element 110 and the support element 112 .
- the connector 110 may be a rod, wire, cable, or rope.
- the connecting element 110 extends between the crossbeam element 108 and the support element 112.
- the suspension 106 can be used to prevent the drive shaft sections 28a and 28b from “hanging down” in their central region or at their connection point VS. As a result, the suspension 106 can also be used to prevent angular offsets at the coupling points KS1 and KS2 (see FIG. 8).
- FIG. 24 shows a view of a tracking device 10 which is designed to support bifacial solar modules 12 .
- Adapter elements 114 and 116 are provided on the tracking device 10 in order to be able to attach bifacial solar modules 12 to the tracking device 10 and to avoid or reduce shading of the back of the module by the mounting rails 22 and 24 .
