Abstract

Toothed belt drive consisting of two toothed pulleys and a toothed belt wrapped around them. To reduce noise, air channels are machined into the toothed pulleys, either in the form of grooves on the circumference between the teeth or as radial holes at the base of the gaps between the teeth. In the case of flanged toothed pulleys, the flanges are perforated or slotted, allowing the air to escape sideways.

Description

Zahnriementrieb Toothed belt drive

Die Erfindung betrifft einen Zahnriementrieb aus zwei Zahnscheiben und einem sie umschlingenden Zahnriemen.The invention relates to a toothed belt drive composed of two toothed pulleys and a toothed belt wrapped around it.

Bei schnellaufenden Zahnriementrieben entstehen erhebliche Geräusche dadurch, daß beim Auflaufen des Zahnriemens auf die Zahnscheiben Luft zwischen dem Zahnriemen und den Zahnscheiben komprimiert wird. Nach DE-OS 21 15 843 soll diese Geräuschentwicklung bei Riemenscheiben verhindert werden, indem die Riemenscheiben aus gesintertem, porösem Material hergestellt werden. Der geräuschmindernde Effekt ist hierbei aber nur gering, da der Luftreibungswiderstand in den engen Poren des Sintermaterials so hoch ist, daß durch sie hindurch die zwischen Riemenscheibe und Riemen befindliche Luft nur schwer entweichen kann.High-speed toothed belt drives generate considerable noises in that when the toothed belt runs up on the pulleys, there is air between the Toothed belt and the toothed pulleys is compressed. According to DE-OS 21 15 843 this should Noise generation from pulleys can be prevented by removing the pulleys be made of sintered, porous material. The noise-reducing effect is only low here, because the air friction resistance in the narrow pores of the Sintered material is so high that through it between the pulley and It is difficult for the air in the belt to escape.

Die Aufgabe der Erfindung liegt darin, der Geräuschbildung bei Zahnriementrieben durch wirkungsvollere, fertigungstechnisch einfache Maßnahmen zu begegnen.The object of the invention is to reduce the generation of noise in toothed belt drives to counteract with more effective, technically simple measures.

Als Lösung dieser Aufgabe werden die im Kennzeichen des Anspruchs 1 genannten Merkmale vorgeschlagen. Weitere die Erfindung ausgestaltende Merkmale enthalten die Unteransprüche.As a solution to this problem, the characteristics of the claim 1 proposed features. Further features defining the invention contain the subclaims.

Durch die erfindungsgemäßen Luftkanäle, die in die Zahnscheiben eingegossen sind oder spangebend eingearbeitet sind, kann die Luft weit besser entweichen als durch mikroskopisch kleine Poren im Material. Es läßt sich mit solchen Luftkanälen auch vermeiden, daß in den Spalt zwischen den ablaufenden Zahnriemen und die Zahnscheibe Luft explosionsartig eingesaugt wird, da der Raum zwischen Zahnriemen und Zahnscheibe über Luftkanäle mit der Umgebungsluft in Verbindung steht und somit immer unter normalem Atmosphärendruck gehalten ist.Through the air channels according to the invention, which are cast into the toothed disks are or are incorporated by cutting, the air can escape much better than through microscopic pores in the material. It can be done with such air ducts also avoid getting into the gap between the unwinding toothed belt and the toothed pulley air is sucked in explosively because the space between the toothed belt and toothed washer is in communication with the ambient air via air ducts and thus is always kept under normal atmospheric pressure.

Besonders wichtig ist die Anbringung von Luftkanälen bei Zahnscheiben, die zur Riemenführung Bordscheiben aufweisen. Durch Schlitze oder Durchgangslöcher in den Bordscheiben läßt sich auf einfachste Weise der seitliche Luftaustritt erreichen.It is particularly important to attach air ducts to tooth lock washers, which have flanged pulleys for belt guidance. Through slots or through holes The side air outlet can be achieved in the flanged disks in the simplest possible way.

Drei Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und werden nachfolgend kurz erläutert.Three embodiments of the invention are shown in the drawings and are briefly explained below.

Es zeigen Fig. 1 Perspektive Teildarstellung eines Zahnriementriebes mit gelochter Bordscheibe Fig. 2 Zahnriementrieb wie Fig. 1, im Querschnitt dargestellt Fig. 3 Zahnscheibe mit Lüftungsnuten am Umfang Fig. 4 Zahnscheibe mit Bohrungen am Zahnlückengrund Die Zahnscheibe 1 nach Fig. 1 und Fig. 2 ist mit einer Bordscheibe 2 versehen, in die jeweils zwischen und oberhalb der Zähne 3 die Bohrungen 4 eingearbeitet sind, die die Bordscheibe 2 quer durchdringen. Wenn der Zahnriemen 5 auf die Zahnscheibe 1 aufläuft, kann die Luft ungehindert durch die seitlichen Bohrungen 4 der Bordscheibe 2 entweichen.1 shows a partial perspective view of a toothed belt drive with a perforated flange plate Fig. 2 toothed belt drive as Fig. 1, shown in cross section Fig. 3 toothed disk with ventilation grooves on the circumference Fig. 4 toothed disk with holes The toothed disk 1 according to FIGS. 1 and 2 has a flanged disk 2, in each of which between and above the teeth 3, the bores 4 are incorporated are that penetrate the flange 2 transversely. When the timing belt 5 on the pulley 1 runs up, the air can unhindered through the side holes 4 of the flange 2 escape.

In Fig. 3 sind am Umfang der Zahnscheibe 6 jeweils am Kopf und am Zahnlückengrund der Zähne 7 Nuten 8 angebracht, die sich über die ganze Zahnbreite erstrecken. Der Luft zwischen Zahnriemen und Zahnscheibe 6 steht somit ein zusätz-licher Raum zur Verfügung, in den sie beim Einlaufen des Zahnriemens verdrängt werden und ins Freie entweichen kann.In Fig. 3 are on the circumference of the toothed disc 6 each on the head and on Tooth gap base of the teeth 7 grooves 8 attached, which extend over the entire tooth width extend. The air between Toothed belt and pulley 6 is up thus an additional space is available in which to enter when the toothed belt runs in can be displaced and escape into the open.

Zusätzlich oder anstelle dieser Nuten 8 kann die Zahnscheibe auch Bohrungen 9 aufweisen, die in Fig. 4 dargestellt sind. Die Bohrungen 9 sind jeweils am Zahnlückengrund etwa mittig zur Zahnbreite angebracht und münden in eine frontal an der Zahnscheibe 10 vorhandene Ringnut 11.In addition to or instead of these grooves 8, the toothed disk can also Have bores 9, which are shown in FIG. The holes 9 are each attached to the base of the tooth gap approximately in the middle of the tooth width and open into a frontal Annular groove 11 present on toothed disk 10.
