Abstract
Description
Im Eingriff miteinander stehende ZahnräderGear wheels in mesh with one another
Stand der Technik Die Erfindung geht aus von Maschinen, die im Eingriff miteinander stehende Zahnräder aufweisen, wie Zahnradgetriebe, Zahnradpumpen, Zahnradmotoren und andere. Es hat sich auch gezeigt, daß dort, wo die im Eingriff miteinander stehenden Zahnräder geschmiert werden, die wechselnden Gleit-und Wälzbedingungen zwischen zwei Zahnflanken zu wechselnden Schmierfilmdicken und damit zu einer schwingenden Relativbewegung der im Eingriff befindlichen Zahnräder führen. Dieser Effekt wirkt sich nachteilig auf das Geräuschverhalten des Zahnradgetriebes aus, was besonders auch für Zahnradpumpen gilt.PRIOR ART The invention is based on machines that are engaged have interconnected gears, such as gear drives, gear pumps, gear motors and other. It has also been shown that where the are in engagement with each other Gears are lubricated, the changing sliding and rolling conditions between two tooth flanks to alternating lubricant film thicknesses and thus to a vibrating one Lead relative movement of the meshing gears. This effect works adversely affect the noise behavior of the gear transmission, which is particularly also applies to gear pumps.
Vorteile der Erfindung Die erfindungsgemäße Anordnung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß der Schmierfilm zwischen zwei sich im Eingriff befindlichen Zahnflanken möglichst konstant gehalten wird, um damit eine Geräuschminderung zu erreichen. Dies hat außerdem den Vorteil, daß die Drehgeschwindigkeit beider im Eingriff bebefindlichen Zahnräder konstant bleibt, d.h. Beschleunigungsspitzen mit daraus folgenden Zahn- bzw. Zahnradschwingungen bleiben aus. Dasselbe gilt für Druckspitzen im Schmierfilm und der damit verbundenen Geräuscherzeugung.Advantages of the invention The arrangement according to the invention with the characterizing Features of the main claim has the advantage that the lubricating film between two tooth flanks that are in mesh are kept as constant as possible, in order to achieve a noise reduction. This also has the advantage that the speed of rotation of both gears in mesh remains constant, i.e. acceleration peaks with resulting tooth or gear vibrations stay out. The same applies to pressure peaks in the lubricating film and the associated ones Noise generation.
Durch die in den Unteransprüchen aufgeführten Merkmale sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen Maßnahmen möglich.The features listed in the subclaims are advantageous Further training and improvements to the measures specified in the main claim are possible.
Zeichnung Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigen Figur 1 zwei im Eingriff befindliche Zahnräder, Figuren 2 und 3 die Zahnflanken zweier Zahnräder.Drawing An embodiment of the invention is shown in the drawing and explained in more detail in the following description. It show figure 1 two meshing gears, Figures 2 and 3 the tooth flanks of two Gears.
t-eschreibung des Ausführungsbeispiels Die Figur 1 zeigt zwei Zähne 10 und 11 zweier im Eingriff befindlichen Zahnräder 12, 13. Das Zahnrad 13 ist das treibende Rad, was durch den Pfeil P gekennzeichnet ist.Description of the exemplary embodiment FIG. 1 shows two teeth 10 and 11 of two meshing gears 12, 13. The gear 13 is that driving wheel, which is indicated by the arrow P.
An der Zahnflanke 10' des Zahns 10 sind in einem mittleren Bereich und über die gesamte Breite b des Zahnes verlaufend eine größere Anzahl von Vertiefungen 14 ausgebildet, siehe hierzu die Figuren 2 und 3. Im Falle des Ausführungsbeispieles nach Figur 2 bestehen die Vertiefungen aus Bohrungen 14' mit geringer Tiefe, die in mehreren übereinanderliegenden Reihen angeordnet sind, von Reihe zu Reihe jedoch gegeneinander versetzt sind. Die Vertiefungen befinden sich in einem Bereich, in dem der Schmierfilm dann - wenn keine besonderen Maßnahmen getroffen sind - dicker ist als in anderen Bereichen; dies ist im allgemeinen der mittlere Bereich bezogen auf die Zahnhöhe h.On the tooth flank 10 'of the tooth 10 are in a middle area and a larger number of recesses running over the entire width b of the tooth 14, see Figures 2 and 3. In the case of the embodiment According to Figure 2, the wells consist of bores 14 'with a small depth, the are arranged in several superimposed rows, but from row to row are offset from one another. The wells are in an area in the lubricating film then - if no special measures are taken - thicker is than in other areas; this is generally related to the middle range to the tooth height h.
Im usführungsbeispiel nach der Figur 3 bestehen die Vertiefungen 14' aus länglichen Querriefen, die ebenfalls in mehreren übereinanderliegenden Reihen angeordnet und zueinander versetzt sind - d.h. so wie im Ausführungsbeispiel nach der Figur 2.In the exemplary embodiment according to FIG. 3, there are depressions 14 ' from elongated cross-grooves, which are also in several superimposed rows are arranged and offset from one another - i.e. as in the exemplary embodiment according to of Figure 2.
Wesentlich ist, daß die Vertiefungen so gestaltet sind,daß beispielsweise bei der Anwendung in einer Zahnradpumpe deren Dichtheit und stoßfreies Gleiten der Zahnflanken aufeinander gewährleistet bleiben. Selbstverständlich sind auch noch andere Vertiefungen oder eine Mischung von Bohrungen und Querriefen denkbar.It is essential that the wells are designed so that, for example when used in a gear pump, its tightness and smooth sliding of the Tooth flanks remain guaranteed on each other. Of course are also still other depressions or a mixture of bores and transverse grooves are conceivable.
Zweckmäßigerweise sind die Vertiefungen nur an einer der beiden miteinander im Eingriff stehenden Zahnflanken ausgebildet, wodurch die Gleiteigenschaften besser sind als dann, wenn an beiden Zahnflanken solche Vertiefungen vorhanden wären. Selbstverständlich sind die beschriebenen Vertiefungen an jedem Zahn eines Zahnrads ausgebildet. Sie können auch am treibenden Rad vorgesehen sein.The depressions are expediently only connected to one another on one of the two engaging tooth flanks formed, whereby the sliding properties better are than if such depressions were present on both tooth flanks. Of course the recesses described are formed on each tooth of a gear. she can also be provided on the driving wheel.
