Definitions
- the present invention relates to a Schrägraffstore with a drive and elevator rollers on which elevator members are wound on which a Lamellenbehang is suspended, wherein the provided on the lower side of Schrägraffstores elevator roller from the drive by means of a switching device can be decoupled.
- the switching device may be formed in such a way that it has a multi-stage planetary gear, the gear stages each having a sun gear, with this meshing planetary gears, a planet carrier supporting them and a ring gear, wherein the winding roller is rotationally coupled to the ring gear of the last gear stage and in the last gear stage between the ring gear and the sun gear or the planet carrier a rotation stop is provided which limits the relative rotation of the ring gear to the planet carrier or sun gear of the last gear, so that when adjacent rotation stop the drive entrains the elevator pulley.
- the object of the invention is to provide a Schrägraffstore with a planetary gear, which can be easily integrated into the upper rail of the system.
- the object is achieved by a Schrägraffstore according to claim 1, wherein the winding roller of the lower side of the plant is arranged on the outer circumference of the ring gear of the last gear stage.
- the ring gears had an outer diameter, which was well above the core diameter of the Auszugsrollen, it has surprisingly been found that it is possible with the inventive design of ring gears and elevator role to arrange them axially practically congruent and thereby the axial space requirement considerably to diminish.
- the planetary gear stages therefore have radial dimensions, which nevertheless allow a design of the elevator pulley with a sufficiently small core diameter on the outer circumference of the ring gears. This makes it possible to integrate the multi-stage planetary gear in the top rail of Schrägraffstores, so that no drive parts more protrude laterally from the rail profile and are exposed to the risk of damage.
- a two-stage planetary gear which is a first, rotationally connected to the drive sun gear, a combing with this set of first planet gears, which are mounted on a first planet carrier, a rotationally connected thereto second sun , Having a meshing with this set of second planetary gears and a second planetary carrier to the storage.
- a two-stage planetary gear which is a first, rotationally connected to the drive sun gear, a combing with this set of first planet gears, which are mounted on a first planet carrier, a rotationally connected thereto second sun , Having a meshing with this set of second planetary gears and a second planetary carrier to the storage.
- the ring gears of the gear stages are rotationally connected to each other.
- about the ring gears and a bearing of the planetary gear is possible.
- the winding roller is arranged axially between the planetary gear sets.
- This embodiment allows the core diameter of the winding roll between the two ring gears, in which the planetary gear sets mesh, radially to draw relatively far inward, without weakening the ring gears.
- the thus possible slightly enlarged outer diameter of the ring gears has a favorable effect on the strength properties, so that less expensive materials for the gears can be used.
- the drive acts in each case via a bevel gear on the elevator rollers, so that they lie with their axes of rotation perpendicular to the shaded wall opening.
- the inventive design of the two-stage planetary gearset allows even in this embodiment to integrate all the parts within the upper rail, although Also, the bevel gear still requires a certain axial space in the region of the axis of rotation of the elevator rollers.
- the advantage of the described arrangement of the elevator rollers is that an entanglement of the elevator members, which are usually designed as elevator belts, in the region of the exit point from the upper rail is not required.
- the ring gears and the elevator pulley can be made in one piece on the lower side of the system, but should an increased strength requirement exist for the teeth, but it is also readily conceivable that ring gears are designed as separate insert elements sitting in inner peripheral surfaces of the elevator pulley.
- the rotation stop is formed on a disc which cooperates with a shoulder on the ring gear, wherein it can be fixed to the second planetary carrier, for example by a releasable clamping seat or a toothing with a sufficiently small tooth width, or even the second Planet carrier forms.
- a so-called elevator bearing 10 an oblique firing system (not shown) is shown, as it comes on the lower-lying plant side used.
- the elevator bearing 10 is mounted in an upper rail and connected via a drive shaft 12 with a drive, not shown.
- the drive shaft 12 also drives a turning device 14 (see Fig. 2 . 5 and 6 ), which acts via a ladder cord 16, on which the slats are suspended, on the curtain to adjust different slat tilt positions can.
- the turning device is known as such and should therefore not be discussed further here.
- the elevator bearing 10 has a housing 18 with a base 20 and a lid 22, which in Fig. 2 is removed to allow insight into the interior of the elevator bearing 10.
- the drive shaft 12 is rotationally connected to a bevel pinion 24, which is in engagement with a bevel gear 26.
- the axis of rotation of the Kegeltellerrades 26 is perpendicular to the surface of the slat slope or perpendicular to the wall opening, which is to be shadowed by the Schrägraffstore.
- an elevator pulley 28 is disposed coaxially with the bevel gear 26.
- Lifting tape wound which is connected to the fall profile of the Lamellenbehangs and with the help of the curtain is einholbar. Since the entry length on the lower side of the system is naturally smaller than on the higher side of the plant, the rotational connection between the bevel gear 26 and the elevator pulley 28 must be interrupted at an appropriate time, the drive then only drives the elevator pulley on the higher side of the plant.
- the drive should first be made exclusively on the higher side of the installation until the fall profile has reached a slope corresponding to the upper rail.
- a switching device 30 between the bevel gear wheel 26 and the elevator pulley 28 then establishes the rotational lock between these two parts, so that in a further catching up also takes place on the lower side of the plant.
- the exact structure and function of the designed as a two-stage planetary gearbox switching device 30 is off 4 to 6 seen.
- the bevel gear 26 is rotationally rigidly connected to an input shaft 32 which extends through the entire planetary gear drive.
- the input shaft 32 is formed with a first sun gear 34 (see Fig. 5 ), which lies in spatial axial proximity to the conical disk wheel 26.
- a first sun gear 34 (see Fig. 5 )
- the first sun gear 34 With three planet wheels 36 which are rotatably mounted in each case a first planet carrier 38.
- the planetary gears 36 further mesh in a ring gear 40.
- the planet carrier 38 is rotationally rigidly connected to a hollow shaft 42, which on the outer circumference of the input shaft 32 relative is mounted rotatably to this.
- the hollow shaft 42 is in its outer periphery with a second sun gear 44 for the second gear stage (see Fig. 6 ) which engages a second set of planet wheels 46, which in turn mesh in a ring gear 48.
- the planet gears 46 are each rotatably mounted on a second planet carrier 50 which is formed as a disc and at its periphery with a radial projection 52 (see Figure 3 ) is formed, which cooperates with an axial projection 54 of the ring gear 48 and forms a rotation stop, which limits the relative rotation between the ring gear 48 and the second planetary carrier 50.
- both ring gears 40, 48 and the winding roller 28 are made as a one-piece part, for example, zinc die casting, ie, both the ring gear 40 of the first gear stage and the ring gear 48 of the second gear 48 are rigidly connected.
- the winding roller is located centrally between the two gear stages and their core diameter 56 is displaced radially inwards, whereby a sufficiently small core diameter 56 for the winding roller 28 can be combined with a diameter of larger diameter for the ring gears 40, 48 that is advantageous for reasons of strength ,
- the planetary gear shown has the advantage that the rotation stop between the second planet carrier 50 and the ring gears always remains closed, as long a load is introduced into the elevator pulley 28 via the elevator belt. But as soon as the drop profile moves against a stop, for example an end stop in the extended end position, the elevator roller 28 stops and the radial projection 52 moves away from the axial projection 54 until the drop profile of the curtain reaches the extended end position also on the higher side of the system.
- the planetary gear with the arranged on the outer circumference of the ring gears 40, 48 elevator pulley 28 is designed to save space and can be easily integrated into the elevator bearings without parts projecting laterally or a particularly large wound reel diameter would be required.
