Abstract
Die Erfindung stellt eine verbesserte Rollenschlepphebeleinheit zur Verfügung, die verbesserte / vergrößerte Flusspfade für die Schmierung aufweist.The invention provides an improved roller cam follower unit having improved / enlarged flow paths for lubrication.
Description
Gebiet der ErfindungField of the invention
Die vorliegende Erfindung bezieht sich auf einen Rollenschlepphebel, und insbesondere bezieht sie sich auf die Schmierung für einen Rollenschlepphebel.The present invention relates to a roller rocker arm, and more particularly relates to the lubrication of a roller rocker arm.
Hintergrundbackground
Anwendungen von Rollenschlepphebeln sind Hertz'schen Pressungen unterworfen, welche in der Regel die empfohlenen Werte für eine zugehörige Lagereinheit überschreiten. Um die Auswirkungen der hohen Pressungen auf Außenlagerring, und auf Achse und Wälzkörper zu mildern, ist es wünschenswert, die Schmieranordnungen zu verbessern.Roller follower applications are subject to Hertzian pressures, which typically exceed the recommended values for an associated bearing unit. In order to mitigate the effects of high pressures on the outer bearing ring, and on the axle and rolling elements, it is desirable to improve the lubrication arrangements.
ZusammenfassungSummary
Die Erfindung stellt eine verbesserte Rollenschlepphebeleinheit zur Verfügung, die vergrößerte / verbesserte Flusspfade für die Schmierung aufweist.The invention provides an improved roller cam follower unit having enlarged / improved flow paths for lubrication.
Kurze Beschreibung der ZeichnungenBrief description of the drawings
Die vorangehende Zusammenfassung und die folgende ausführliche Beschreibung werden durch Bezugnahme auf die beigefügten Zeichnungen besser zu verstehen sein. In den Zeichnungen ist eine bevorzugte Ausführung der Erfindung dargestellt. Die Figuren zeigen:The foregoing summary and the following detailed description will be better understood by reference to the accompanying drawings. In the drawings, a preferred embodiment of the invention is shown. The figures show:
Ausführliche Beschreibung der bevorzugten AusführungenDetailed description of the preferred embodiments
Bestimmte, in der nun folgenden Beschreibung verwendete Begriffe dienen lediglich der Bequemlichkeit und sind keineswegs als einschränkend zu verstehen. Die Begriffe „vorder...“, „hinter...“, „ober...“ und „unter...“ beziehen sich auf Richtungen in den Zeichnungen, auf welche hierin Bezug genommen wird. Die Begriffe “nach innen“ und „nach außen“ beziehen sich auf Richtungen zu oder weg von den in den Zeichnungen mit Bezugszahlen gekennzeichneten Teilen. „Axial“ bezieht sich auf eine Richtung entlang einer Achse einer Welle. Ein Bezug auf eine Liste von Posten bzw. Teilen mit der Formulierung „mindestens eines von a, b, oder c“, (worin a, b und c für die aufgezählten Posten stehen), bedeutet irgendeinen der aufgelisteten Posten a, b, oder c oder Kombinationen aus diesen Posten. Die Terminologie schließt die konkret genannten Begriffe, Ableitungen daraus und Begriffe mit ähnlicher Bedeutung ein.Certain terms used in the following description are for convenience only and are not to be construed as limiting. The terms "front ...", "behind ...", "upper ..." and "below ..." refer to directions in the drawings referred to herein. The terms "inward" and "outward" refer to directions to or away from the parts identified by reference numerals in the drawings. "Axial" refers to a direction along an axis of a shaft. A reference to a list of items having the phrase "at least one of a, b, or c" (where a, b, and c are the enumerated items) means any one of listed items a, b, or c or combinations of these items. The terminology includes the terms specifically mentioned, derivatives thereof, and terms of similar meaning.

Nach der vorhergehenden ausführlichen Beschreibung der vorliegenden Erfindung, muss es verstanden werden und für den Fachmann klar und naheliegend sein, dass zahlreiche physische Änderungen, von denen nur einige in der vorhergehenden ausführlichen Beschreibung beispielhaft angeführt sind, vorgenommen werden könnten, ohne die hierin verkörperten erfinderischen Ideen und Prinzipien zu verändern. Es muss auch verstanden werden, dass zahlreiche Ausführungen, welche nur Teile der bevorzugten Ausführung beinhalten, möglich sind, und, mit Bezug auf diese Teile die hierin verkörperten erfinderischen Ideen und Prinzipien der Erfindung nicht verändern. Aus diesem Grund sind die vorliegende Ausführung und optionale Ausbildungen der Erfindung in jeder Hinsicht als beispielhaft und/oder als erklärend und nicht als einschränkend zu verstehen, weil der Schutzbereich der Erfindung durch die angeführten Ansprüche angegeben wird und nicht durch die vorhergehende Beschreibung, so dass alle alternativen Ausführungen und an der vorliegenden Ausführung vorgenommenen Änderungen, welche im Sinne der Ansprüche zu verstehen sind und im Gleichwertigkeitsbereich der Ansprüche liegen, somit durch die Ansprüche abgedeckt sind.After the foregoing detailed description of the present invention, it must be understood and obvious to those skilled in the art that numerous physical changes, of which only some are exemplified in the foregoing detailed description, could be made without the inventive concepts embodied herein and change principles. It should also be understood that numerous embodiments incorporating only portions of the preferred embodiment are possible, and with respect to these parts, are not alteratory of the inventive concepts and principles of the invention embodied herein. For this reason, the present embodiment and optional embodiments of the invention are to be considered in all respects as illustrative and not restrictive, as the scope of the invention is indicated by the appended claims rather than the foregoing description, so that all alternative embodiments and changes made to the present embodiment, which are to be understood in the sense of the claims and are within the range of equivalence of the claims, thus covered by the claims.
