Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft ein Wälzlager, insbesondere Nadellager, mit zylindrischen, die Last übertragenden Wälzkörpern (Lastrollen) und zwischen diesen angeordneten Trennrollen, wobei die Trennrollen einen kleineren Durchmesser aufweisen als die Lastrollen und innerhalb des Teilkreises der Lastrollen angeordnet sind. Außerdem betrifft die Erfindung einen Ventiltrieb mit diesem Wälzlager.The The invention relates to a roller bearing, in particular a needle roller bearing, with cylindrical, the load transmitting rolling elements (Load rollers) and arranged between these separating rollers, wherein the separating rollers have a smaller diameter than the load rollers and are arranged within the pitch circle of the load rollers. Furthermore The invention relates to a valve train with this rolling bearing.
Hintergrund der ErfindungBackground of the invention
Ein
derart gattungsgemäß ausgebildetes Wälzlager
ist aus der
Nachteilig dabei ist, dass ein solches Wälzlager aufgrund der verschiedenartigen Trennrollen, die innerhalb und außerhalb des Teilkreises angeordnet sind, sehr aufwändig zu fertigen ist. Es ist weiter von Nachteil, dass sich die Lastrollen und die innerhalb des Teilkreises angeordneten Trennrollen sowie der Lagerinnenring ständig berühren, d. h., die Reibung in diesem Lager ist hoch, was sich negativ auf das Laufverhalten auswirkt.adversely It is the case that such a rolling bearing due to the various Separating rollers inside and outside the pitch circle are arranged, very expensive to manufacture. It is further disadvantage that the load rollers and within the Partial circle arranged separating rollers and the bearing inner ring constantly touch, d. h., the friction in this camp is high, which has a negative effect on the running behavior.
Zusammenfassung der ErfindungSummary of the invention
Ausgehend von den Nachteilen des bekannten Standes der Technik liegt der Erfindung daher die Aufgabe zugrunde, ein gattungsgemäßes Wälzlager mit Trennrollen derart zu verbessern, dass es wesentlich weniger reibbelastet ist.outgoing from the disadvantages of the known prior art is the invention therefore the object of a generic To improve roller bearings with separating rollers such that it is much less frictional load.
Erfindungsgemäß wird diese Aufgabe nach dem kennzeichnenden Teil von Anspruch 1 in Verbindung mit dessen Oberbegriff dadurch gelöst, dass die Durchmesser von Lastrollen und Trennrollen so aufeinander abgestimmt sind, dass unter Berücksichtigung eines Teilkreisspiels pro Lastrolle und unter Berücksichtigung des Teilkreisendspiels aller Lastrollen unabhängig vom jeweiligen Betriebszustand des Wälzlagers der Durchmesser der Trennrollen größer als ein variabel sich einstellendes Teilkreisspiel zwischen zwei beliebigen benachbart angeordneten Lastrollen ist, wobei die Trennrollen in radialer Richtung eine Bewegung ausführen können, die einerseits von einer Innenlaufbahn des Wälzlagers und andererseits von je einer Mantelfläche zweier benachbart angeordneter Lastrollen begrenzt ist.According to the invention this object according to the characterizing part of claim 1 in conjunction solved with the preamble by the fact that the diameter of load rollers and separating rollers are coordinated so that taking into account a partial cycle clearance per load roller and considering the pitch circle of all Load rollers independent of the respective operating condition of the rolling bearing the diameter of the separating rollers is greater than one variably adjusting subgroup play between any two adjacent load rollers is, the separating rollers in radial direction can perform a movement, on the one hand by an inner race of the bearing and on the other each of a lateral surface of two adjacently arranged Load rollers is limited.
Der vorteilhafte Unterschied gegenüber dem bisherigen Stand der Technik liegt darin, dass den Trennrollen eine Möglichkeit zu einer radialen Bewegung zwi schen Innenlaufbahn und Außenlaufbahn eingeräumt ist. Diese Bewegung wird in radialer Richtung nach außen durch die Anlage der Trennrollen an den Mantelflächen zweier benachbart angeordneter Lastrollen begrenzt. Mit steigender Drehzahl heben die Trennrollen aufgrund der Fliehkraft von der Innenlaufbahn ab, sodass der Reibkontakt mit dieser aufgehoben ist, was sich positiv auf das Laufverhalten der Lageranordnung auswirkt, weil die Reibung verringert ist. Auf diese Weise ist ein Wälzlager mit zylindrischen Last- und Trennrollen gebildet, das gegenüber einer vollrolligen Ausführung bei nahezu gleicher Tragfähigkeit eine wesentlich geringere Reibung realisiert und das gegenüber einer Käfigvariante aufgrund der erhöhten Anzahl von Wälzkörpern eine höhere Tragfähigkeit aufweist.Of the advantageous difference compared to the previous state The technique lies in the fact that the separating rollers a possibility granted to a radial movement between the inner raceway and outer raceway is. This movement is in the radial direction to the outside by the plant of the separating rollers on the lateral surfaces of two adjacent arranged load rollers limited. With increasing speed lift the separation rollers due to the centrifugal force of the inner raceway so that the frictional contact with this is canceled, which is positive affects the running behavior of the bearing assembly, because the friction is reduced. In this way is a rolling bearing with cylindrical Load and separating rollers formed, compared to a full complement Design with almost the same load capacity realized much lower friction and that opposite a cage variant due to the increased number of rolling elements a higher load capacity having.
Beim Umlauf eines Wälzlagers durchlaufen die Wälzkörper abwechselnd eine belastete und eine unbelastete Zone, wobei die Belastung der einzelnen Wälzkörper beginnend beim Einlauf in die Lastzone ständig ansteigt, bis sie in der Position des Scheitelwälzkörpers das Belastungsmaximum erreicht hat. Von da an schwächt sich die Belastung wieder ab, bis sie in der lastfreien Zone zu Null wird. Entsprechend der Wälzkörperbelastung ergibt sich auch eine elastische Verformung der Laufbahnen. Dadurch erhalten die einzelnen Wälzkörper auch bei konstanter Lagerdrehzahl unterschiedliche Umlaufgeschwindigkeiten. Wenn diese Geschwindigkeitsunterschiede auch nur minimal sind, so verursachen sie dennoch eine Abstandsänderung der einzelnen Wälzkörper in Umfangsrichtung voneinander, insbesondere in der Lastzone. Dies hat zur Folge, dass, bezogen auf die Erfindung, die Lastrollen in Umfangsrichtung ständig ihren Abstand voneinander ändern, d. h., das Teilkreisspiel zwischen den einzelnen Lastrollen wird sich ständig verändern. Dies bedeutet, an einer Stelle in Umfangsrichtung liegen die Lastrollen mit ihren Mantelflächen näher aneinander, während sie beispielsweise an der entgegengesetzten Richtung den größten Abstand voneinander aufweisen können. Das erfindungsgemäße Wälzlager ist daher so auszulegen, dass die Trennrollen und die Lastrollen bezüglich ihres Durchmessers so dimensioniert ausgelegt sind, dass die Trennrollen auch bei einem größtmöglichen Abstand zweier benachbart angeordneter Lastrollen in Umfangsrichtung zwischen diesen nicht hindurch rutschen können.At the Circulation of a rolling bearing pass through the rolling elements alternately a loaded and an unloaded zone, the Load of individual rolling elements starting at Enema in the load zone is constantly increasing until it is in the Position of the vertex body the load maximum has reached. From then on the load weakens again until it becomes zero in the no-load zone. According to the Wälzkörperbelastung also results in an elastic Deformation of the raceways. This gives the individual rolling elements even at constant bearing speed different rotational speeds. If These speed differences are only minimal, so cause Nevertheless, they change the distance of the individual rolling elements in the circumferential direction from each other, especially in the load zone. This has the consequence that, based on the invention, the load rollers in Circumferential direction constantly changing their distance from each other, d. h., the partial circle play between the individual load rollers becomes to change constantly. This means at one Position in the circumferential direction are the load rollers with their lateral surfaces closer to each other, for example, while the opposite direction the greatest distance may have from each other. The invention Rolling bearings must therefore be designed so that the separating rollers and the load rollers are dimensioned with respect to their diameter are designed so that the separation rollers even at the greatest possible distance two adjacently arranged load rollers in the circumferential direction between this can not slip through.
Es hat sich in Weiterbildung der Erfindung als vorteilhaft erwiesen, dass die Lastrollen und die Trennrollen einem gleichen Durchmesserbereich zugeordnet sind, wobei nach einem weiteren Merkmal der Erfindung die Zuordnung in Schritten von jeweils einem μm erfolgt. Durch diese Zupaarung von Lastrollen und Trennrollen zu den vorhandenen Laufbahnen wird es möglich, dass erstens ein optimales Betriebsspiel eingestellt ist und dass zweitens die Einstellung so erfolgt, dass es auch unter Berücksichtigung der unterschiedlichen Teilkreisspiele und des Teilkreisendspieles ausgeschlossen ist, dass eine Trennrolle zwischen den Lastrollen hindurch rutschen kann.It has been developed by the invention proved to be advantageous that the load rollers and the separating rollers are assigned a same diameter range, wherein according to a further feature of the invention, the assignment in steps of one micron takes place. By this pairing of load rollers and separating rollers to the existing raceways, it is possible that, firstly, an optimal operating clearance is set and second, the setting is made so that it is excluded even taking into account the different pitch circle games and the Teilkreisendspieles that a separation role between the load rollers can slip through.
Ein weiterer Gegenstand der Erfindung ist ein Ventiltrieb zur Betätigung eines Gaswechselventils einer Brennkraftmaschine, bestehend aus einem Nockenfolger, der von einem mit einer Nockenwelle verbundenen Nocken über eine Rolle beaufschlagt ist, wobei diese über ein Wälzlager drehbar auf einem Bolzen gehalten ist. Nach der Erfindung ist das Wälzlager als ein Nadellager gemäß den Ansprüchen 1–3 ausgebildet. Auf diese Weise ist ein besonders reibungsarmer Ventiltrieb geschaffen, der eine Spritersparnis realisiert. Es wurde nämlich gefunden, dass die Reibung in einem Zylinderkopf einer Brennkraftmaschine zu einem wesentlichen Anteil auf Nockenfolger zurückgeht, deren wälzgelagerte Rolle vom Nocken beaufschlagt ist.One Another object of the invention is a valve drive for actuation a gas exchange valve of an internal combustion engine, consisting of a cam follower connected by a camshaft Cam is acted upon by a roller, these over a rolling bearing is rotatably supported on a bolt. To the invention is the rolling bearing as a needle bearing according to the Claims 1-3 formed. That way is a particularly low-friction valve train created that saves fuel realized. It was found that the friction in a cylinder head of an internal combustion engine to a substantial Share on cam follower goes back, whose roller bearings Roller is acted upon by the cam.
Nach
