These tracks may be adapted in cross-section to a longitudinal section through a rolling element along the axis of rotation thereof; To increase the life of such storage, the raceways can be additionally hardened.
  • the axial extent of the respective pivot unit is minimized in the direction of the respective bearing axis of rotation.
  • At least one respective annular structure of a swivel unit can have a toothing, preferably an external toothing.

  • An external toothing is not only suitable for the engagement of a pinion, but is also suitable for the meshing engagement of a worm.
  • toothing is located on the same lateral surface as the roller bearing (s), in particular on the lateral surface facing the gap.
  • Another measure for reducing the axial height of a pivoting unit is that the toothing is located in the axial direction between two rolling bearings.

  • a gear can be provided between pinion or worm and drive motor, in particular a reduction gear.
  • the invention further provides that a ring is formed as the toothing encompassing housing. This protects the gearing against contamination.
  • the ring designed as a toothing should be provided with a somewhat radial extension, in which a drive means meshing with the toothing is accommodated, while a drive motor rotatably coupled to the drive means is preferably located outside this housing widening.
  • the radial extension of the ring formed as a housing surrounds a (one) with the teeth of the other ring meshing (-s) worm or pinion.
  • a further design provision provides that a (e) meshing with the toothing of the other ring pinion or worm is mounted in / at the radial extension of the housing formed as a ring.
  • the invention can be further developed such that the housing or chassis or the stator of a drive is connected or coupled to the common mounting assembly.
  • a motor therefore moves with respect to all connected system parts at most about a single axis, which facilitates the electrical contacting of the power lines.
  • a device in which at least one pivoting unit is equipped with a drive worm, is preferably characterized by at least one braking device, which is connected on the one hand to the worm engaging or connectable and on the other hand supported on the formed as a housing ring or a connected or connectable part ,
  • a braking device is primarily assigned the task of avoiding unwanted rotation of one connected part of the plant in relation to the other or with respect to the foundation in the stopped state, so that the relevant drive motor can be switched off in order to save energy.
  • the braking device has no switching elements, the probability of failure can be kept within the smallest limits. It has proven to be advantageous that the braking device permanently generates a braking effect, that is never deactivated, not even when adjusting the beireffenden pivot unit.
  • the braking device should have a passive brake, ie without supply of auxiliary power, so that it consumes no additional energy.
  • the arrangement in the static, ie stopped state is completely energy neutral, which is important especially in solar systems in terms of good efficiency.
  • a simple realization of the braking device succeeds in that it has friction discs rubbing against each other with a normal force acting perpendicular to the discs, so that the generated friction torque is independent of the direction of rotation. It may be a housing fixed to the housing and a disk rotatable with the screw, or one or two packages of a plurality of disks.
  • the normal forces of the discs rubbing against one another preferably always act in the same, preferably in the axial direction of the worm. This can be achieved in a simple way, characterized in that the friction surfaces are arranged approximately perpendicularly penetrated by the axis of the screw.
  • the braking device may be a functionally separate from the worm brake, although acting on the same rotary shaft, but is not integrated with the worm, but only coupled thereto. As a result, the production of these highly different elements is decoupled from each other and thus simplified.
  • the braking torque from the braking device is permanently introduced into the worm shaft independently of the direction of rotation. This is an undesirable pulling through a load in any direction of rotation safely excluded, unlike, for example, when acting only in one direction of rotation freewheel.
  • the braking torque is transmitted from the braking device to the worm shaft by a positive engagement acting in the tangential direction.
  • a positive engagement acting in the tangential direction for example, can be used with a drive shafts known tongue and groove principle with two extending in the axial direction of the worm shaft and with each other fleeing grooves, wherein a common keyway can be used.
  • the braking device is not located between, but axially outside the pivot bearing of the worm shaft, so that the distance between these pivot bearings must not be increased and thus the precision of the storage of the screw is not affected.
  • the invention undergoes further optimization in that the direction of the brake is arranged in the region of an end face of the worm, which is not coupled or can be coupled to a drive motor.
  • the drive motor can be flanged directly in the region of a rotary bearing of the worm shaft to the housing, and this results in a particularly torsion-rigid arrangement, which allows a highly accurate Einsteiiung and compliance with a rotational position.
  • the braking torque of the braking device is on or adjustable, so it can be an optimal compromise between the desired self-locking of the worm gear on the one hand and a minimal braking effect on the other hand, to demand the drive motor for adjustment only a minimum of additional energy.
  • a worm gear which in itself is not self-locking; the self-locking effect instead generates the brake according to the invention.
  • the elements of the brake in particular friction surfaces and possibly spring elements, should be arranged in a preferably bell-shaped housing.
  • a particularly advantageous arrangement is characterized in that the common mounting assembly for connecting one or both pivoting units (each) has a flat pad. It has been proven that flat pads can be produced with the highest possible precision. In addition, the balance of power on such flat surfaces are particularly überschau- and manageable. Also, there can be provided perpendicular thereto connecting or connecting elements, for example. Arranged in a circle around the axis of rotation bores, which pass through the relevant pad vertically.
  • the invention further provides that at least one flat connection surface of the common assembly assembly for connection of a pivot unit has an opening.
  • pads can also be provided on the mutually corresponding end faces of both annular structures, ie in the same axial direction, for connection to the common mounting assembly on the one hand and to a foundation or plant component on the other hand.
  • the aperture should have a circular shape in a flat pad of the common mounting assembly, preferably with a diameter equal to or greater than the radially inner ring of the pivoting unit to be fixed thereto.
  • the common mounting assembly can be formed such or their pads can be aligned so that the two axes of rotation of the connected to the common mounting assembly pivot units are inclined or inclined to each other.
  • the common mounting assembly should be designed such or their pads to be aligned such that the two axes of rotation of the connected to the common mounting assembly pivot units lie in a common plane. If the two axes of rotation of the pivoting units connected to the common assembly assembly intersect, in particular at an angle which is not equal to zero, the free connection surface of the non-anchored pivoting unit can be moved along a spherical surface by combined adjustment of both pivoting units about their respective axes of rotation, the center thereof is defined by the intersection of both axes of rotation.
  • the adjustment is independent of an adjustment to each of the two axes of rotation other axis of rotation. Aligning the free pad of the non-anchored pivot unit in a desired direction is therefore particularly easy.
  • the axis of rotation of the pivot unit connected to a foundation can be exact be set vertically, so that can be aligned by adjusting this pivoting unit, the common assembly assembly in any direction, while the axis of rotation of the second pivoting unit remains exactly horizontal at all SchwenksteHept and thus allows the setting of the topocentric elevation angle.
  • the course of the sun can be tracked at any time exactly if their direction or azimuth and altitude are known.
  • Such a decoupling of the two rotational positions can be particularly easily achieved in that the common mounting assembly has two Anschiußfikieen which are perpendicular to each other, so that in particular the axes of rotation connected thereto pivot units are perpendicular to each other.
  • the common mounting assembly can be further developed to the effect that one of their pads rises vertically above its other pad, so is not offset laterally beyond the edge.
  • the center of gravity of the common assembly assembly and in particular also the center of gravity of the entire slewing mechanism lies above a pivoting unit to be connected to a foundation, and then to a support, column or other foundation as well as to the respective pivoting unit itself will not act in a free state from external forces too big overturning moments.
  • the invention recommends that the planes of the two Anschiußfiamba the common assembly assembly intersect along a line which is offset from the centers of the two pads.
  • the center of gravity of the entire swing can be moved exactly to a vertically oriented axis of rotation of the biaxial slewing, so that on the respective pivot unit itself in From external forces free state at most minimal or ideally no tilting moments act.
  • a particularly simple arrangement results by forming at least one pad by a plate.
  • a flat plate always has a flat connection surface, so that this - in addition to the cutting of a desired plate circumference - no special measures are required.
