Abstract
Description
Rolle, bestehend aus einem Hålzlager und einerRoll, consisting of a wood storage and a
Scheibe Die Erfindung bezieht sich auf eine Rolle gemäR dem Oberbegriff des ersten Anspruchs.Disc The invention relates to a roller according to the preamble of the first claim.
Rollen der obengenannten Art, z. B. aus Eunststoff, sind allgemein bekannt. Sie werden beispielsweise als Spannrollen auf den verschiedensten Gebieten benutzt. Aus verschiedenen Gründen wurden die Scheiben im mittleren Bereich mit Aussparungen versehen. Im Laufe der Zeit wurden. aber immer höhere Anforderungen insbesondere an ihre äußere Lauffläche gestellt. An diesen Stellen entstehen insbesondere bei Vorhandensein von axial gerichteten Versteifungsrippen wellige Bläschen.Roles of the type mentioned above, e.g. B. made of plastic are general known. They are used, for example, as tensioning pulleys in a wide variety of areas used. For various reasons the discs were in the middle area with Provide recesses. Over time were. but ever higher demands especially placed on their outer tread. At these points arise in particular in the presence of axially directed stiffening ribs, wavy bubbles.
Diese können insbesondere bei hohen Drehzahlen negative Einwirkungen auf die mit den Spannrollen versehenen Systeme bringen.These can have negative effects, especially at high speeds bring them onto the systems provided with the tensioning pulleys.
Es ist daher Aufgabe der Erfindung, Rollen auf zu zeigen, deren äußere Lauffläche durch die Versteifungsmittel bei der Herstellung nicht wellig wird.It is therefore an object of the invention to show roles on the outer The tread does not become wavy due to the stiffening means during manufacture.
Die Lösung dieser Aufgabe ist im kennzeichnenden Teil des ersten Anspruchs enthalten. Die Ansprüche 2 bis 4 enthalten spezielle Ausgestaltungen.The solution to this problem is in the characterizing part of the first claim contain. Claims 2 to 4 contain special designs.
Die im geringen Abstand angeordneten runden Vertiefungen in der Scheibe enthalten nicht nur die bisherigen Vorteile in Form von z.B. wenig Materialbedarf und geringem Gewicht, sondern sie bewirken auch, daß die Mantelflache der Scheibe bei hohen Drehzahlen nicht wellig wird. Die radiale Verbindung zwischen den Scheibenteilen erfolgt nämlich kontinuierlich und mit stark. gekrümmten Sbergängen.The small spaced round recesses in the disc not only contain the previous advantages in the form of e.g. little material requirement and light weight, but they also cause the outer surface of the disc does not become wavy at high speeds. The radial connection between the disc parts namely occurs continuously and with strong. curved sumps.
Weitere Vorteile bestehen darin, daß sich wegen der kontinuierlichen Wandstärkeübergänge wenig Verzug und kurze Spritzzeiten ergeben. Weiterhin werden Verspannungen, die zu Scheibenrissen führen können, vermieden.Other advantages are that because of the continuous Wall thickness transitions result in little distortion and short injection times. Continue to be Tension, which can lead to cracks in the pane, is avoided.
Wenn die Vertiefungen etwa in der Mitte der Scheibe einen Boden besitzen, ergeben sich im Querschnitt etwa H-förmige Ausführungen, die eine höhere Formstabilität in radialer Richtung besitzen. Um etwa gleiche Wandstärken mit ihren bekannten Vorteilen zu erreichen ist es zweckmäßig, die Vertiefungen in zwei radial und/oder in Umfangsrichtung zueinander versetzten Reihen anzuordnen. Ähnliches wird auch erreicht, wenn die Vertiefungen jeder Reihe voneinander abweichende Durchmesser besitzen.If the depressions have a bottom approximately in the middle of the disc, The result is an approximately H-shaped cross-section that provides greater dimensional stability own in the radial direction. Around the same wall thickness with their known advantages It is useful to achieve the depressions in two radial and / or circumferential directions to arrange staggered rows. Something similar is achieved when the Wells in each row have different diameters.
Die Erfindung wird anhand von vier Figuren näher erläutert.The invention is explained in more detail with reference to four figures.
Fig. 1 zeigt eine erfindungsgemäße Ausführung in Teilquerschnitt Fig. 2 zeigt eine axiale Draufsicht auf die Ausführung nach Fig. 1 Fig. 3 zeigt eine Variante zu Fig. 1 Fig. 4 zeigt eine axiale Draufsicht auf die Ausführung nach Fig. 3 Die Fig. 1 zeigt eine Riemenscheibe 1 mit einem zweireihigen Kugellager 2. Die H-förmige Gestalt entsteht durch die an beiden Stirnseiten angebrachten, großen runden Vertiefungen 3, wobei etwa in der Mitte der Scheibe 1 ein Boden 4 zur Versteifung vorgesehen ist Damit die Wandstärken etwa gleich bleiben, ist rioch eine R.-it-.e von kleinen Vertiefungen 5 angebracht, .Je ebenLalls einen Boden besitzen.Fig. 1 shows an embodiment according to the invention in partial cross-section. 2 shows an axial plan view of the embodiment according to FIG. 1. FIG. 3 shows a Variant of FIG. 1 FIG. 4 shows an axial plan view of the embodiment according to FIG. 3 Fig. 1 shows a pulley 1 with a two-row ball bearing 2. The The H-shaped shape is created by the large ones attached to both ends round depressions 3, approximately in the middle of the disc 1, a bottom 4 for stiffening is provided So that the wall thicknesses remain roughly the same, a R.-it-.e of small wells 5 attached, each also have a bottom.
Die Fig. 3 und 4 zeigen eine Variante zu Fig. 1 und 2. Hier sind in der Scheibe 8 jeweils zwei Reihen von Vertiefungen vorgesehen, wobei die größeren Vertiefungen 6 im Bereich der Mantelfläche 7 vorgesehen sind, während die kleineren Vertiefungen 9 dazu versetzt auf einem kleineren Durchmesser liegen.3 and 4 show a variant of FIGS. 1 and 2. Here, in the disc 8 each provided two rows of depressions, the larger Depressions 6 are provided in the area of the lateral surface 7, while the smaller Wells 9 offset to lie on a smaller diameter.
