Description
Freilaufkupplung Die Erfindung betrifft eine Freilaufkupplung, bei der Klemmrollen oder Klemmkugeln mit den Klemmflächen eines gegossenen Klemmrings zusammenwirken.Overrunning clutch The invention relates to an overrunning clutch, at the clamping rollers or clamping balls with the clamping surfaces of a cast clamping ring cooperate.
Es ist bereits ein Freilaufstern bekannt, der im Spritz-oder Druckgußverfahren hergestellt ist. Da dieser bekannte Freilaufstern als Guß stück nicht gehärtet werden kann, weisen seine Klemmflächen nur eine niedrige Belastbarkeit und eine geringe Verschleißfestigkeit auf.A freewheel star is already known, which is injection-molded or die-cast is made. Since this well-known freewheel star is not hardened as a cast piece can, its clamping surfaces have only a low load capacity and a low Wear resistance.
Die Lebensdauer einer Freilaufkupplung mit einem bekannten gegossenen Freilaufstern ist daher gering.The life of a one-way clutch with a known cast Free wheel star is therefore low.
Der Erfindung liegt die Aufgabe zugrunde, diesen Nachteil zu beseitigen und es wird erfindungsgemäß eine Freilaufkupplung mit einem gegossenen Klemmring vorgeschlagen, dessen Klemmflächen mit gehärteten Blechteilen verstärkt sind. Die Blechteile können entweder lose eingelegt oder auch in dafür vorgesehene Nuten eingeklemmt werden. Nach einer Ausführungsform der Erfindung ist es auch möglich, die gehärteten Blechteile auf die Klemmflächen aufzukleben.The invention is based on the object of eliminating this disadvantage and there is, according to the invention, an overrunning clutch with a cast clamping ring proposed whose clamping surfaces are reinforced with hardened sheet metal parts. the Sheet metal parts can either be loosely inserted or clamped in the grooves provided for this purpose will. According to one embodiment of the invention, it is also possible to use the hardened Glue sheet metal parts on the clamping surfaces.
Bei einer Freilaufkupplung, deren Klemmrollen durch Federelemente gegen die Klemmflächen angefedert sind, sieht eine Ausführungsform der Erfindung vor; daß die federelernente mit den gehärteten Blechteilen einstückig ausgeführt sind. Dies bringt erhebliche Vereinfachungen bei der Fertigung und bei der Montage.In the case of a one-way clutch, its pinch rollers are fitted with spring elements are sprung against the clamping surfaces, provides an embodiment of the invention before; that the spring element is made in one piece with the hardened sheet metal parts are. This brings considerable simplifications in production and assembly.
Bei einer Freilaufkupplung mit einem gegossenen Klemmring, dessen Klemmflächen mit gehärteten Blechteilen verstärkt sind, wird die Belastbarkeit und die Verschleißfestigkeit so erhöht, daß dieser Freilauf auch für Anwendungsfälle mit höherer Beanspruchung eingesetzt werden kann.In the case of a one-way clutch with a cast clamping ring, whose Clamping surfaces are reinforced with hardened sheet metal parts, the load capacity and the wear resistance is increased so that this freewheel is also suitable for applications can be used with higher loads.
Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und werden im folgenden näher beschrieben. Es zeigen: Fig. 1 einen teilweisen Querschnitt durch eine erfindungsgemäße Freilaufkupplung, Fig. 2 einen teilweisen Längsschnitt durch-die Freilaufkupplung der Figur 1, Fig. 3 einen teilweisen Querschnitt durch eine andere Ausführungsform einer erfindungsgemäßen Freilaufkupplung.Embodiments of the invention are shown in the drawings and are described in more detail below. They show: FIG. 1 a partial cross section through an overrunning clutch according to the invention, FIG. 2 is a partial longitudinal section through the overrunning clutch of FIG. 1, FIG. 3 shows a partial cross section through another embodiment of a one-way clutch according to the invention.
Im Ausführungsbeispiel der Figuren 1 und 2 ist der als Guß stück ausgebildete Klemmring 1 mit einstuckigen Stegen 2 versehen, zwischen denen die Klemmrollen 3 aufgenommen sind.In the embodiment of Figures 1 and 2 is formed as a cast piece The clamping ring 1 is provided with one-piece webs 2, between which the clamping rollers 3 are included.
Die Stege 2 weisen axial verlaufende Nuten zur Aufnahme von Federelementen 4 auf, mit denen die Klemmrollen 3 gegen die Klemmflächen angefedert sind. Die Klemmflächen sind mit gehärteten Blechteilen 5 verstärkt.The webs 2 have axially extending grooves for receiving spring elements 4, with which the pinch rollers 3 are spring-loaded against the clamping surfaces. The clamping surfaces are reinforced with hardened sheet metal parts 5.
An der linken Seite des Klemmrings 1 ist der Bord 6 einstückig angegossen, während die rechte Seite des Klemmrings durch den Blechring 7 abgeschlossen ist. Der Blechring kann zugleich als Dichtung ausgebildet sein. Die teilzylindrischen Flächen 8 in der Bohrung des Käfigs und die Bohrung 9 des Bordes 6 sind als Gleitflächen für eine in den Klemmring 1 einzusetzende Welle oder für einen glattzylindrischen Innenring gestaltet.On the left side of the clamping ring 1, the board 6 is cast in one piece, while the right side of the clamping ring is closed by the sheet metal ring 7. The sheet metal ring can also be designed as a seal. The part-cylindrical Areas 8 in the bore of the cage and the Hole 9 of the board 6 are used as sliding surfaces for a shaft to be inserted into the clamping ring 1 or for designed a smooth cylindrical inner ring.
In Figur 3 ist eine Freilaufkupplung dargestellt, deren Klemmrollen 3 durch Federelemente in Umfangsrichtung gegen die entsprechenden Klemmflächen angefedert sind. Zur Vereinfachung von Fertigung und Montage sind an die. gehärteten Blechteile 10 die Federelemente 11 einstückig angeformt.In Figure 3, a one-way clutch is shown, its pinch rollers 3 sprung by spring elements in the circumferential direction against the corresponding clamping surfaces are. To simplify production and assembly, the. hardened sheet metal parts 10, the spring elements 11 are formed in one piece.
