Abstract

1. Drive for the winding spindle of a curtain or roller blind having a wheel (7) which can be driven by means of a cord, is rotatably mounted in a housing (2), which is to be arranged in a stationary manner, and is connected through gearing by means of a planetary gear unit with a cam (14, 15) which can be mounted on the winding spindle (1) in a manner secure against rotation, with a helical spring brake (12), which rubs on a cylindrical surface (11) secure with respect to the housing and axially surrounds the cam (14, 15), preventing the cam (14, 15) from turning relative to the wheel (7) and with, further, an element (9) which turns with the wheel (7) interfering with the path of rotation of the cam (14, 15) and releasing the helical spring brake (12) upon rotation of the wheel (7), characterised in that the wheel (7) has an inner ring gear (8) which mates with at least one planet pinion (10) which is rotatably mounted on the plate-like element (9) axial to the wheel and which operates a ring gear (5) which is secure with respect to the housing, is concentric to the internally toothed ring gear (8) and is secure with respect to the housing (sic).

Description

Die vorliegende Erfindung bezieht sich auf einen Antrieb für die Aufzugswelle eines Stores gemäss dem Oberbegriff des Anspruchs 1.The present invention relates to a drive for the elevator shaft of a store according to the preamble of claim 1.

Ein derartiger Antrieb ist aus der DE-A1-2 620 808 bekannt. Mit diesem ist es möglich vergleichsweise schwere Rolladenpanzer mit zumutbarem Kraftaufwand zu heben und zu senken. Diese vorbekannte Druckschrift zeigt zwei Ausführungsformen solcher Antriebe. Bei der ersten ist der Innenzahnkranz und bei der zweiten der Planetenradträger feststehend angeordnet. Bei beiden Ausführungsformen ist der Innenzahnkranz vom Kugelkettenrad getrennt. Sie liegen nebeneinander. Ebenfalls getrennt ist die Kupplung. Diese Teile sind in Richtung der Aufzugswelle nebeneinander angeordnet, wodurch sowohl in radialer als auch in achsialer Richtung grosse Getriebeabmessungen entstehen. Zudem erfordern solche Getriebe mehr Einzelteile, was ihre Herstellung einschliesslich ihres Zusammenbaus verteuert.Such a drive is known from DE-A1-2 620 808. With this it is possible to raise and lower comparatively heavy roller shutter curtains with reasonable effort. This previously known document shows two embodiments of such drives. In the first, the internal ring gear and in the second, the planet carrier is fixed. In both embodiments, the internal ring gear is separated from the ball sprocket. They are next to each other. The clutch is also separated. These parts are arranged side by side in the direction of the elevator shaft, which results in large transmission dimensions both in the radial and in the axial direction. In addition, such gears require more individual parts, which makes their manufacture, including their assembly, more expensive.

Die vorliegende Erfindung stellt sich die Aufgabe, ein Antrieb der erwähnten Art derart zu verbessern, dass unter Wahrung des Vorteils einer geringen Aufziehkraft die Baugrösse des Antriebs möglichst klein gestaltet werden kann.The object of the present invention is to improve a drive of the type mentioned in such a way that the size of the drive can be made as small as possible while maintaining the advantage of a low pulling force.

Erfindungsgemäss wird diese Aufgabe gelöst durch die kennzeichnenden Merkmale des Anspruchs 1.According to the invention, this object is achieved by the characterizing features of claim 1.

Anhand der beiliegenden schematischen Zeichnung wird die Erfindung beispielsweise erläutert. Es zeigen:

  • Fig. 1 einen Schnitt längs der Linie I - in Fig. 2,
  • Fig. 2 einen Schnitt längs der Linie 11 - 11 in Fig. 1 und
  • Fig. 3 einen Schnitt längs der Linie 111 - 111 in Fig. 2.
The invention is explained, for example, with the aid of the attached schematic drawing. Show it:
  • 1 shows a section along the line I - in Fig. 2,
  • Fig. 2 shows a section along the line 11 - 11 in Fig. 1 and
  • 3 shows a section along the line 111-111 in FIG. 2.

Das Ende einer Aufzugswelle 1 eines Stores oder Rolladens ist drehbar in einem Antriebsgehäuse 2 gelagert. Das Gehäuse 2 weist einen Deckel 3 mit einem nach innen weisenden Lagerauge 4 auf, das mit einem Aussenzahnkranz 5 versehen ist.The end of an elevator shaft 1 of a store or roller shutter is rotatably mounted in a drive housing 2. The housing 2 has a cover 3 with an inwardly facing bearing eye 4, which is provided with an external ring gear 5.

Der Deckel 3 ist fest mit dem Gehäusekörper 6 verbunden. Im Gehäuse 2 ist ein Kugelkettenrad 7 drehbar gelagert, das als Ring mit einem Innenzahnkranz 8 ausgebildet ist. Innerhalb des Kugelkettenrades 7 ist achsial zur Aufzugswelle 1 ein scheibenförmiges Organ 9 angeordnet, welches, mindestens eines, vorzugsweise drei Planetenritzel 10 trägt, die daran drehbar gelagert sind. Die Planetenritzel 10 kämmen einerseits mit dem Aussenzahnkranz 5 und anderseits mit dem Innenzahnkranz 8. Wird das Kugelkettenrad 7 gedreht, laufen die Planetenritzel 10 auf dem Aussenzahnkranz 5 ab und drehen das Organ 9 mit kleinerer Umfangsgeschwindigkeit als das Kugelkettenrad 7 mit. Das Untersetzungsverhältnis beträgt in etwa 1 : 1.8. In das Gehäuse 2 ist weiter eine Bremsbüchse 11 fest eingesetzt, die eine zylindrische Innenfläche bildet. In die Bremsbüchse 11 achsial eingesetzt ist eine Schraubenbremsfeder 12, deren Enden 13 nach innen abgewinkelt sind.The cover 3 is firmly connected to the housing body 6. In the housing 2, a ball chain wheel 7 is rotatably mounted, which is designed as a ring with an internal ring gear 8. Within the ball chain wheel 7, a disk-shaped member 9 is arranged axially to the elevator shaft 1, which carries at least one, preferably three, planet pinions 10, which are rotatably mounted thereon. The planetary pinions 10 mesh on the one hand with the external ring gear 5 and on the other side with the internal ring gear 8. If the ball sprocket 7 is rotated, the planetary pinions 10 run on the external ring gear 5 and rotate the member 9 at a lower peripheral speed than the ball chain sprocket 7. The reduction ratio is approximately 1: 1.8. In the housing 2, a brake sleeve 11 is also firmly inserted, which forms a cylindrical inner surface. A helical brake spring 12, the ends 13 of which are angled inwards, is inserted axially into the brake sleeve 11.

Achsial in die Schraubenfeder 12 ist weiter ein Mitnehmer 14 eingesetzt, der eine nach innen vorspringende Rippe 15 aufweist, die in eine Längsnut 16 der Aufzugswelle 1 eingreift. Der Mitnehmer 14 ist daher mit der Aufzugswelle 1 drehfest verbunden. Die Enden 13 der Schraubenfeder 12 liegen zwischen den Enden des im Querschnitt ringsegmentförmigen Mitnehmers 14. Zwischen die beiden Enden 13 greift ein Arm 17 des scheibenförmigen Organs 9 und liegt im Drehweg des Mitnehmers 14.A driver 14 is further inserted axially into the helical spring 12, which has an inwardly projecting rib 15 which engages in a longitudinal groove 16 of the elevator shaft 1. The driver 14 is therefore rotatably connected to the elevator shaft 1. The ends 13 of the helical spring 12 lie between the ends of the driver 14, which has a ring-shaped cross section. Between the two ends 13, an arm 17 of the disk-shaped member 9 engages and lies in the rotational path of the driver 14.

Bei stillstehendem Kugelkettenrad 7 erzeugt ein auf die Aufzugswelle 1 wirkender Lamellenpanzer ein Drehmoment, das die Aufzugswelle 1 und den Mitnehmer 14 drehen will. Dadurch kommt der Mitnehmer 14 mit einem der Federenden 13 in Anschlag und weitet die Schraubenfeder 12 derart aus, dass diese gegen die Bremsbüchse 11 drückt und die Aufzugswelle 1 bremst. Wird das Kugelkettenrad 7 gedreht, dreht sich das Organ 9 mit und der Arm 17 kommt mit einem der Federenden 13 in Anschlag, lockert die Bremse und trifft dann auf den Mitnehmer 14 und dreht nun die Aufzugswelle 1 mit. Sobald das Drehen des Kugelkettenrades 7 unterbrochen wird, drückt der Mitnehmer 14 wieder auf eines der Federenden 13 und verhindert eine Drehung der Aufzugswelle 1 relativ zum Gehäuse 2.When the ball sprocket 7 is stationary, a lamellar armature acting on the elevator shaft 1 generates a torque which the elevator shaft 1 and the driver 14 want to rotate. As a result, the driver 14 comes to a stop with one of the spring ends 13 and expands the helical spring 12 in such a way that it presses against the brake sleeve 11 and brakes the elevator shaft 1. If the ball sprocket 7 is rotated, the member 9 rotates with it and the arm 17 comes into abutment with one of the spring ends 13, loosens the brake and then hits the driver 14 and now also rotates the elevator shaft 1. As soon as the rotation of the ball chain wheel 7 is interrupted, the driver 14 presses again on one of the spring ends 13 and prevents rotation of the elevator shaft 1 relative to the housing 2.
