Definitions

  • the invention relates to a bearing arrangement for a drive pulley, in particular for an awning, and an awning itself equipped therewith.
  • Awnings of this type have an awning curtain and a supporting frame with lateral guide rails for the awning curtain running in the projection direction of the awning curtain. End rails running transversely to the guide rails, which are used for stationary mounting of the awning on a building and/or on supports.
  • the awning curtain is connected at its drop-out end to a drop-out profile, which can be extended and retracted in and against the drop-out direction by a drive belt driven in at least one of the guide rails in the drop-out direction.
  • the endless, circulating drive belt is guided at the output end of the guide rail via a deflection roller and at the other end via a drive pulley, which is rotatably mounted via a roller bearing in at least one bearing cheek of the guide rails and is driven by a motor.
  • the drive pulley is mounted via roller bearings, which are accommodated in a bearing shell in a bearing cheek of the guide rails.
  • Bearing shell could be designed as a bore where the connection to the outer ring of the roller bearing has a transition fit with very narrow tolerances is. In terms of production practice, this means that the hole is made with a smaller dimension by laser processing and the close-tolerance fitting dimension is reworked. Only a laser contour without post-processing is too roughly tolerant, so that the roller bearing then has too much play or is under too much pressure. In the latter case, the outer bearing ring can be so tight that the roller bearing becomes stiff.
  • the above solution has the disadvantage that after the laser machining of the bearing shell and clamp, these components still have to be machined so precisely that the clamp can first be screwed onto the bearing cheek without any problems. After that, further post-processing must be carried out in order to ensure the snug fit of the roller bearing in the combination of bearing shell and clamp.
  • the invention is based on the object of providing a bearing arrangement for a Indicate drive pulley in particular for use in an awning that can be manufactured with less tight tolerances and post-processing effort.
  • the bearing shell and/or clamp is provided with at least one elastic loading element, by means of which the roller bearing is held braced in the bearing shell.
  • a one-piece design of the at least one activating element with the bearing shell or the clamp further simplifies production.
  • the at least one loading element can be flanked by a fixed stop. This limits the degrees of freedom mentioned above, which benefits a defined bearing of the roller bearing. This has a particularly positive effect when the fixed stop is arranged between the free ends of two oppositely arranged wing-like extensions as the loading element.
  • the invention also relates to the use of the bearing arrangement according to the invention in an awning.
  • Two bearing cheeks, each with one of the bearing arrangements, are then preferably provided on the aforementioned lateral guide rail of the awning, between the axial alignments of roller bearings a drive disk sits connected via a drive shaft to the roller bearings.
  • This has a rectangular support frame 1 seen from above, which is composed of lateral guide rails 3, 4 running in the projection direction A of an awning curtain 2 and end rails 5, 6 connecting their ends.
  • the awning housing 5 which is usually referred to as the awning housing 5 and houses the electric drive for the awning curtain 2
  • the awning is mounted on a building wall 7 via appropriate brackets (not shown), the opposite end rail 6 rests on Supports 8, 9, which are, for example, on a terrace 10 to be covered.
  • the awning curtain 2 is an awning fabric 12 which, with its end pointing in the direction of projection A, is fastened in a projection profile 11 which runs transversely to the direction of projection A and is driven in this direction so as to be displaceable in the guide rails 3, 4.
  • the awning fabric 12 is also divided into individual strip zones 13 like a canopy and fastened to a fabric support profile 14 with the edge of each of its zones 13 .
  • the latter are guided with their ends freely in the guide rails 3, 4 in the direction of projection A and move under the influence of gravity and the tensile effect of the projection profile 11 from a retracted position of the awning with downward-hanging folds of the individual strip zones 13 - 2 and 3 - into the in 1 and 4 shown, extended position in which the awning fabric 12 with the fabric support profiles 14 is pulled through the driven front profile 11 in the direction of failure A and is just stretched when it reaches the bottom rail 4 on the front side.
  • the displaceability of the cloth support profiles 14 in the guide rails 3, 4 is achieved by a running rail arrangement as shown in 3 is shown in detail.
  • the guide rails 3, 4 each have a track 16 realized by inner profile webs 15—see FIG 3 - On, in each of which the cloth support profiles 14 carrying carriages 17 run on corresponding pairs of rollers 18 along.
  • the four rollers 18 of the two pairs of rollers per carriage 17 are rotatably mounted on a bearing body 19 of the carriage 17 .
  • the drop profile 11 and the cloth support profiles 14 are mounted at their ends 20 via a bearing axis 21 on the respective carriage 17 .
  • the drop profile 11 is connected via its carriage 17 to a drive belt 22 designed as an endless toothed belt, which runs around the two ends of the guide rails 3, 4 via deflection rollers.
  • the deflection roller on the side of the awning housing 5 is realized by a drive pulley 23 and in particular in 4 recognizable with its square opening 24.
  • a drive shaft 25 connected to an electric motor drive of the awning in the awning housing 5 engages in this—see FIG figure 5 and shown broken away 7 - non-rotatable. The retracting and extending movement of the awning curtain 2 described above can thus be accomplished via a corresponding reversing actuation of the drive pulley 23 .
  • bearing arrangement LA according to the invention of the drive pulley 23 is now in particular based on the Figures 4 to 7 described in more detail.
  • two congruently designed and horizontally aligned bearing cheeks 26 are attached to the guide rail 3 in the form of a flat bar contoured comparatively roughly by laser cutting, each of which has a semicircular bearing shell 27 .
  • a roller bearing 28 flanking the drive disk 23 on the opposite sides is inserted and held by a clamp 31 which can be fixed by screws 29 , 30 on the respective bearing cheek 26 .
  • the clamp 31 On the side of the clamp 31 facing the outer ring 32 of the roller bearing 28, the latter is provided with two elastic loading elements 33, 34 made in one piece from the clamp material, which are each designed as wing-like extensions 35 running approximately tangentially to the outer ring 32. These stand with their free ends 36 directed towards each other and are positioned in the unassembled initial state so that they engage in the assembly of the clamp 31 in the contour space of the roller bearing.
  • a fixed stop 37 is also integrally formed on the clamp 31, by which the deflection of the extensions 35 is limited radially outwards relative to the outer ring 32 of the roller bearing 28.
  • the drive shaft 25 with the drive pulley 23 and the two roller bearings 28 is inserted into the bearing shells 27 .
  • the clamp 31 is fixed with the help of the screws 29, 30, whereby the screw connection through the mutual stop shoulders 38, 40 on the bearing shell 27 and clamp 31 can simply be done "on block” regardless of the tolerance conditions.
  • the elastic loading elements 33, 34 increasingly load the outer ring 32 of the respective roller bearing 28, the extensions 35 are thus correspondingly elastically deflected and load the outer ring 32 with a radially inwardly directed, sufficient force component K.
  • the bearing is thus tolerance-compensated, at the same time the roller bearing 28 is positioned in a sufficiently defined manner and secured against rotation, without the holding forces on the outer ring 32 becoming so high that the roller bearing would become distorted with corresponding sluggishness.
  • the tensile forces of the drive belt 22, represented by the arrow Z are also compensated with the aid of the loading elements 33, 34.
