Description

Der Gegenstand der vorliegenden Erfindung verbessert die Bauweise von die Bewegung einer Maschine steuernden Wellen, beispielsweise Exzenterwellen, und ist insbesondere fürNockenwellen von .Bremskraftmaschinen, vorgesehen, bei der jeder über den Wellendurchmesser hinausragende Teil der Nockenwelle auf der Welle befestigt ist.The subject matter of the present invention improves construction of shafts controlling the movement of a machine, e.g. eccentric shafts, and is especially intended for camshafts of .Brake engines, in which any part of the camshaft on the shaft that protrudes beyond the shaft diameter is attached.

Die Erfindung besteht hierbei @darin, daß der Nocken,auf den Wellenteil jeweils in der erforderlichen, beliebig wählbaren Winkelstellung aufschiebbar und festklemmbar sowie ohne Vornahme irgendwelcher Veränderung oder Zerstörung eines Bauteiles vom Wellenteil wieder lösbar ist mittels eines Lagers, welches z. B. aus einem an sich bekannten, mit Gewinde und Feststellmutter versehenen, geschlitzten Spannring besteht, auf dem der mit einem entsprechenden Innenkonus versehene Nocken aufschiebbar und auf dem er feststellbar ist.The invention consists in that the cam on the shaft part each in the required, freely selectable angular position can be pushed and clamped as well as without making any change or destruction of a Component from the shaft part is detachable again by means of a bearing which, for. B. off one known per se, provided with a thread and a locking nut, slotted There is a clamping ring on which the cam provided with a corresponding inner cone can be pushed open and on which it can be locked.

An- sich ist es bereits bekannt, Spannhülsen od. dgl. mit Gewinde und Mutter zum Aufschieben auf eine Welle und zum Festklemmen der ihnen zugeordneten Maschinenteile auf .der Welle zu verwenden (Kugellager, Bundring ,zur Axialbegrenzung einer Kurbelwelle). Bei diesen bekannten Ausbildungen handelt es sich aber lediglich um ein. Festklemmen .auf einer tragenden Welle, nicht aber um das Festklemmen eines Steuernockens in einer zwar genauestens vorgeschriebenen, aber .beliebig wählbaren Winkelstellung auf einer :die Bewegung einer Maschine steuernden Welle.It is already known per se to have clamping sleeves or the like with a thread and nut for sliding onto a shaft and for clamping the associated one To use machine parts on the shaft (ball bearings, collar ring, for axial limitation a crankshaft). In these known trainings, however, it is only around a. Clamping. On a supporting shaft, but not about clamping one Control cam in a precisely prescribed, but freely selectable Angular position on a shaft that controls the movement of a machine.

Es sind. auch bereits mehrtenlige Nockenwellen für Brennkraftm@aschinen bekanntgeworden. So wurde eine von einem Reguliator verstellbare mehrteilige Daumenscheibe bekannt, die aus vier Teilen besteht, und zwar aus einem auf der Welle festgekeilten Teil und drei hintereinanderliegenden Zusatzteilen.There are. also multi-part camshafts for internal combustion engines known. This is how a multi-part thumb disk that can be adjusted by a regulator was created known, which consists of four parts, namely one wedged onto the shaft Part and three additional parts lying one behind the other.

Diese fächerartig und aus mehreren Einzelnocken bestehende Einrichtung ist im Gegensatz zum Gegenstand der Erfindung immer an eine Arretierung gebunden. Es ist bei der bekanntgewordenen. Einrichtung nicht möglich, das Steuerdiagramm auf jeden beliebigen Grad und Winkelwert und auf die größtmögliche Feinheit einzustellen. Die Einstellung-des Winkelwertes nach der bekanntgemachten Einrichtung kann nur sprunghaft sein, da dort ein auf der Welle starr befestigter Mutternocken vorgesehen -ist, an den sich fächerartig drei weitere Nocken entsprechend der jeweils gewählten Verstellburkeit anschließen.This fan-like device consisting of several individual cams In contrast to the subject matter of the invention, it is always linked to a lock. It is the one that has become known. Cannot set up the tax chart to any degree and angle value and to the greatest possible fineness. The setting of the angle value according to the announced device can only be leaps and bounds, since a nut cam is provided there that is rigidly attached to the shaft -is, on which three more cams fan-like according to the selected one Connect adjustability.

Ferner sind verschiedene Steuerwellen bekanntgeworden, bei der,die Nocken festgekeilt und durch Stift gegen axiale Verschiebung gesichert werden. Der Nachteil bei aufgekeilten Nocken ist immer der, daß beim jeweiligem Verändern, der Lage in Achsrichtung oder beim Verändern des Steuerdiagriamms neu aufgekeilt, also eine Abänderung der Keilnut im Wellen- oder im Nockenteil vorgenommen werden ruß.Furthermore, various control waves have become known in which, the Cams are wedged and secured against axial displacement by a pin. Of the The disadvantage of wedged cams is always that when changing, the Position in the axial direction or when changing the control diagram re-wedged, i.e. a modification of the keyway in the shaft or in the cam part can be made soot.

Hingegen besitzt die vorliegende Erfindung den Vorteil eines in, axialer Richtung und auf jeden beliebigen Winkelwert festklemmib@aren, jederzeit und ohne irgendwelche Veränderung oder Zerstörung eines Bautei,1es lösbaren Einizelnockens.In contrast, the present invention has the advantage of being in, axial Direction and can be clamped to any angle value, at any time and without any change or destruction of a component, 1s detachable single cam.

Die Erfindung ist in der Zeichnung in einem Ausführungsbeispiel veranschaulicht, und zwar zeigt Abb. i die zum Festklemmen eines Nockens auf den tragenden Wellenteil erforderlichen Teile im Schaubild, Abb. 2 die festgeklemmten Teile in, Seitenansicht und Abb. 3 die festgeklemmtenTeile inVorderansicht. Irr Abb. i ist der beiderseits abgebrochene tragende Wellenteil i und die danebenliegende Buchse 2 dargestellt. Diese mit Außenkonus versehene Buchse 2 besitzt einen Längsschlitz 3, beginnt vorn mit dem einer Mutter nachgebildeten Halteteil ¢ und endet mit dem Gewindeteils. Der Nocken 6 besitzt einen, entsprechenden, Innenkonus zum Aufschieben auf Buchse 2. Diese Buchse 2 wird auf den tragenden Wellenteil i an die erforderliche Stelle geschoben und der Nocken 6 seinerseits, in der erforderlichen, Winkelstellung auf den Außenkonus ,der Buchse 2 geschoben und das Ganze mittels der Mütter 7 auf den tragenden Wellenteil i Die Abb. 2 und 3 zeigen die festgeklemmten Teile in Seiten- und Vorderansicht.The invention is illustrated in the drawing in an exemplary embodiment, namely Fig. i shows the clamping of a cam on the supporting shaft part required parts in the diagram, Fig. 2 the clamped parts in, side view and Fig. 3 shows the clamped parts in front view. Irr Fig. I is the one on both sides broken supporting shaft part i and the adjacent bushing 2 shown. This socket 2, which is provided with an outer cone, has a longitudinal slot 3, starts at the front with the retaining part ¢ simulating a nut and ends with the threaded part. The cam 6 has a corresponding inner cone to be pushed onto the socket 2. This bushing 2 is placed on the supporting shaft part i at the required point pushed and the cam 6 in turn, in the required angular position the outer cone, the socket 2 pushed and the whole thing by means of the nuts 7 on the supporting shaft part i Figs. 2 and 3 show the clamped parts in side and front view.

Auf diese Weise ist jede Anzahl von Nocken. und Lagerstellen aufschiebbar und an den erforderlichen Stellen und bei den Nocken in jeder gewünschten Winkelstellung festklemmbar.That way is any number of cams. and bearings can be pushed open and at the required locations and at the cams in any desired angular position clampable.
