Abstract
Description
Betr.: Patentanmeldung mit Gebrauchsmuster-Hilfsanmeldung für Kettenrad für Kettenantriebe und Kettenfahrzeuge, die in Schmutz arbeiten Die Erfindung betrifft ein Kettenrad für Kettenantriebe, die in Schmutz und Schlamm arbeiten.Re: Patent application with utility model auxiliary application for sprocket for chain drives and tracked vehicles working in dirt The invention relates to a sprocket for chain drives that work in dirt and mud.
Die bekannten Kettenräder sind so konstruiert, daß die Kettenbuchsen in den Zahumulden der Antriebsräder zur Anlage kommen. Laufen diese Kettenräder mit ihren Ketten nun in Schmutz und Schlamm, so daß sich der Schmutz zwischen die Kettenbuchsen und Zahnmulden der Kettenräder setzt, so verändert sich durch die Schautzschicht der Fußkreisdurchmesser des Antriebsrades und somit auch der Teilkreisdurchmesser, was bedeutet, daß die Teilung der Kette kleiner ist, als die Teilung des Kettenrades.The known chain wheels are designed so that the chain bushes come to rest in the grooves of the drive wheels. Are those sprockets running with their chains now in dirt and mud, so that the dirt is between the The chain sockets and toothed hollows of the sprockets are changed by the Protective layer of the root diameter of the drive wheel and thus also the pitch circle diameter, which means that the pitch of the chain is smaller than the pitch of the sprocket.
Durch diese Deilungsveranderung des Kettenrades steigt die Kette in dem Kettenrad auf, wird dadurch unnötig hoch belastet mit dem Resultat eines höheren Verschleißes und eines eventuellen Kettenbruches.This change in the division of the sprocket causes the chain to rise in the sprocket, is thereby unnecessarily heavily loaded with the result of a higher Wear and tear and a possible chain break.
Bei einigen Kettenantrieben wird nicht nur die Eettenkraft durch das Antriebsrad in Zugrichtung übertragen, Abb. I, sondern auch - insbesondere bei Kettenfahrzeugen -das Auflage gewicht der Maschine von der Kettenbuchse auf das Kettenrad übertragen, Abb. II + III.With some chain drives, not only the chain force is increased by the Transfer the drive wheel in the pulling direction, Fig. I, but also - especially with tracked vehicles -the bearing weight of the machine is transferred from the chain bushing to the sprocket, Fig. II + III.
Das Kettenrad, Abb. I, für'die Kettenantriebe hat.nur die Aufgabe, die Kette zu ziehen. Das.Kettenrad für Eettenfahrzeuge, Abb. II + III, hat die Aufgabe, die Kette zu ziehen unddas Fahrzeug zu tragen.The chain wheel, Fig. I, for the chain drives has only the task of to pull the chain. The task of the chain wheel for Eettenfahrzeuge, Fig. II + III, is to pull the chain and carry the vehicle.
Die Erfindung zeichnet sich nun dadurch aus, daß.Versuche an Kettenantrieben gezeigt haben, daß sich die Kette an einem Kettenrad, bei dem die Zahnmuide so ausgebildet ist, daß die Kettenbuchse zur Eettenradmitte nicht zur Auflage kommt, insbesondere im Schmutz besser abläuft., als ein Kettenrad, bei dem die Kettenbuchse in der Zahnmulde zur Radmitte hin aufliegt. Bei Kettenrädern, bei denen'zwischen Kettenbuchse und unterer Zahnmulde viel Platz ist, legt sich die Kettenbuchse - bedingt durch die Kettenteilung -nur an der Zahnflanke des Kettenrades an, d.h. die Kettenbuchse hat nur eine Auflagefläche, das ist die Zahnflanke, und nicht zwei wie die Zahnflanke und die untere Zahnmulde.The invention is now characterized in that attempts on chain drives have shown that the chain is attached to a sprocket in which the tooth muide is so formed is that the chain bushing does not come to rest in the middle of the Eettenrad, in particular runs better in dirt than a sprocket with the chain bushing in the tooth recess rests towards the center of the wheel. In the case of sprockets where 'between the chain bush and there is a lot of space in the lower tooth recess, the chain bushing lies down - due to the Chain pitch - only on the tooth flank of the sprocket, i.e. the chain bushing has only one contact surface, that is the tooth flank, and not two like the tooth flank and the lower tooth cavity.
Wird nämlich die untere Zahnmulde durch eingedrungenen Schmutz nach außen hin erhöht, so wird die Kettenbuchse durch den vorhandenen Schmutz weiter nach außen verlegt, das bedeutet, der Teilkreisdurchmesser wird vergrößert und der Ablauf zwischen Kette und Kettenrad ist gestört.Namely, the lower tooth recess after penetrating dirt increased towards the outside, the chain bushing is widened by the existing dirt relocated to the outside, that means, the pitch circle diameter is enlarged and the Process between chain and sprocket is disturbed.
Durch die Maßnahme, die gettenmulde eines Kettenrades zur Kettenradmitte hin zu verlegen, so daß möglichst viel tuft zwischen der Kettenbuchse und der Zannmulde entsteht, verhindert das Aufbauen von Schmutz und somit das Aufsteigen der Kette auf den nächsten Zahn, was eine '0berbelastung der Kette und des gesamten Antriebes bedeuten würde.By the measure, the gettenmulde of a chain wheel to the chain wheel center to relocate so that as much tuft as possible between the chain bushing and the Zannmulde prevents the build-up of dirt and thus the chain from climbing up to the next tooth, which overloads the chain and the entire drive would mean.
