Description
Die Erfindung bezieht sich auf einen Sicherungsring mit einem in eine Aufnahmenut einer Welle oder einer Bohrung einsetzbaren Ringkörper, der einen Ringspalt zwischen gleich langen spaltseitigen Endabschnitten aufweist, welche in radialer Richtung auf der bei Gebrauch von der Aufnahmenut abgewandten Seite gegenüber dem sich daran anschließenden Bereich des Ringkörpers verbreitert sind, um eine durch unterschiedliche Zentrifugalkräfte bei rotierendem Ring auftretende Unwucht auszugleichen.The invention relates to a retaining ring with an insertable into a receiving groove of a shaft or a bore annular body having an annular gap between the same gap-side end portions which in the radial direction on the side facing away from the receiving groove in use relative to the adjoining region of Ring body are widened to compensate for an occurring by different centrifugal forces with a rotating ring unbalance.
Ein Sicherungsring dieser Art, auch als Sprengring bezeichnet, ist in der
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Sicherungsring der eingangs genannten Art mit für die Herstellung und Funktion verbesserten Eigenschaften bereit zu stellen.The present invention has for its object to provide a locking ring of the type mentioned with improved for the production and function properties.
Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst. Hierbei ist vorgesehen, dass der Ringkörper bis auf die Endabschnitte gleichbleibenden Querschnitt aufweist und die Masse der Endabschnitte pro Längeneinheit in Umfangsrichtung so gewählt ist, dass die durch den Ringspalt hervorgerufene Unwucht ausgeglichen ist.This object is achieved with the features of
Der Ringkörper, der bis auf die Endabschnitte gleichbleibende radiale Breite aufweist, lässt sich vorteilhaft und präzise herstellen und ergibt eine stabile, in Umfangsrichtung gleichbleibende Abstützfläche und Aufnahme axial wirkender Kräfte. Dabei sind die auf beiden Seiten des Ringspalts liegenden Endabschnitte in ihrer radialen Breite so dimensioniert, dass eine Unwucht, die durch die fehlende Masse im Spaltbereich auftreten würde, kompensiert bzw. ausbalanciert wird. Die beiden Endabschnitte sind dabei bezüglich der Winkelhalbierenden des Spaltöffnungswinkels symmetrisch geformt.The ring body, which has the same radial width except for the end portions, can be produced advantageously and precisely and results in a stable, circumferentially constant support surface and receiving axially acting forces. The lying on both sides of the annular gap end portions are dimensioned in their radial width so that an imbalance that would occur due to the lack of mass in the gap area is compensated or balanced. The two end portions are symmetrically formed with respect to the bisector of the gap opening angle.
Eine für die Fertigung und Funktion vorteilhafte Ausgestaltung besteht dabei darin, dass der Sicherungsring in seinem freien Nichtgebrauchszustand in einem solchen Ausmaß unrund geformt ist, dass er beim Einsatz in eine Aufnahmenut über seinen gesamten Umfang am Nutgrund gleichmäßig anliegt, wobei die Dimensionierung der Endabschnitte auf den Ausgleich der Unwucht im eingesetzten Zustand abgestimmt ist. Mit diesen Maßnahmen wird die Kompensation der Unwucht wegen der gleichmäßigen Massenverteilung in Umfangsrichtung im Gebrauchszustand weiter verbessert und zudem auch ein präziser Sitz des Sicherungsrings in der Aufnahmenut erreicht, so dass auch über den Umfang des Ringkörpers die axialen Abstützkräfte homogen verteilt sind.An advantageous embodiment for the manufacture and function consists in that the circlip in its free non-use state is formed out of round to such an extent that it uniformly rests on the groove base when used in a receiving groove over its entire circumference, wherein the dimensioning of the end portions on the Balancing the imbalance in the inserted state is tuned. With these measures, the compensation of imbalance due to the uniform mass distribution in the circumferential direction in the use state is further improved and also achieved a precise fit of the locking ring in the receiving groove, so that the axial support forces are distributed homogeneously over the circumference of the ring body.
