Abstract
Description
Die Erfindung betrifft eine Axialfixierungsanordnung für einen auf einer Welle gehaltenen Drehkörper, umfassend eine um eine Drehachse D zur Übertragung eines Drehmoments antreibbare Welle und einen Drehkörper, der auf der Welle drehfest und in zumindest einer Längsrichtung über ein in einer Umgangsnut der Welle einsitzendes erstes Sicherungselement axial unverschiebbar gehalten ist.The invention relates to an Axialfixierungsanordnung for a held on a shaft rotary body, comprising a shaft rotatable about a rotational axis D for transmitting a shaft and a rotary body which rotatably on the shaft and axially in at least one longitudinal direction via a eineingendes in a Umgangsnut the first fuse element is held immovable.
Die
Die Aufgabe der vorliegenden Erfindung besteht darin, eine Axialfixierungsanordnung für einen auf einer Welle gehaltenen Drehkörper bereitzustellen, die ein verbessertes Verschleißverhalten über eine relevante Betriebsdauer aufweist.The object of the present invention is to provide an axial fixing arrangement for a rotary body supported on a shaft, which has an improved wear behavior over a relevant period of operation.
Die Aufgabe wird gelöst durch eine Axialfixierungsanordnung für einen auf einer Welle gehaltenen Drehkörper, umfassend eine um eine Drehachse D zur Übertragung eines Drehmoments antreibbare Welle, einen Drehkörper, der auf der Welle drehfest und in zumindest einer Längsrichtung über ein in einer Umgangsnut der Welle einsitzendes Sicherungselement axial unverschiebbar gehalten ist, wobei das Sicherungselement über ein in das Sicherungselement und in eine Längsnut der Welle eingreifendes Arretierungselement gegen Relativdrehung gegenüber der Welle drehfest gehalten ist.The object is achieved by an axial fixing arrangement for a rotary body held on a shaft, comprising a shaft which can be driven about an axis of rotation D for transmitting a torque, a rotary body which is rotationally fixed on the shaft and in at least one longitudinal direction via a securing element located in a circumferential groove of the shaft is held axially immovable, wherein the securing element is held against rotation via a locking element engaging in the securing element and in a longitudinal groove of the shaft against relative rotation relative to the shaft.
Hierbei ist von Vorteil, dass das Sicherungselement durch das Arretierungselement gegen eine Relativdrehung gegenüber der Welle arretiert beziehungsweise gehalten ist. Weiterhin ist gewährleistet, dass der Montageablauf bezüglich des ersten Sicherungselements unverändert vorgenommen werden kann und lediglich in einem zusätzlichen Montageschritt das Arretierungselement angeordnet werden muss. Der Drehkörper ist erfindungsgemäß konzentrisch und umfänglich zu der Welle angeordnet. Der Drehkörper ist bevorzugt über eine Längsverzahnung drehfest gegenüber der Welle gehalten.It is advantageous that the securing element is locked or held by the locking element against relative rotation with respect to the shaft. Furthermore, it is ensured that the assembly process can be carried out unchanged with respect to the first securing element and only in an additional assembly step, the locking element must be arranged. The rotary body is arranged according to the invention concentrically and circumferentially to the shaft. The rotary body is preferably rotatably held against the shaft via a spline.
Bevorzugt umschließt das Arretierungselement das Sicherungselement umfänglich. Hierdurch wird eine insbesondere in axialer Richtung platzsparende Anordnung gewährleistet. Desweiteren wird hierdurch ein ungewolltes Aufweiten des Sicherungsrings unterbunden, so dass ein Auswandern des Sicherungsrings aus der Umfangsnut der Welle nicht möglich ist.Preferably, the locking element surrounds the securing element circumferentially. As a result, a space-saving arrangement, in particular in the axial direction, is ensured. Furthermore, an unwanted widening of the securing ring is thereby prevented, so that an emigration of the securing ring from the circumferential groove of the shaft is not possible.
Bevorzugt umschließt ein Umfangsabschnitt des Arretierungselements das Sicherungselement umfänglich, wobei der Umfangsabschnitt eine Rastnase zum radialen Eingriff in die Längsnut der Welle und zum Eingriff in das Sicherungselement ausbildet. Durch die Rastnase wird in einfacher Weise ein Formschlusselement bereitgestellt, mit dem das Sicherungselement mittelbar mit der Welle in Eingriff gebracht werden kann.Preferably, a peripheral portion of the locking element encloses the securing element circumferentially, wherein the peripheral portion forms a latching nose for radial engagement in the longitudinal groove of the shaft and for engagement in the securing element. By the latching lug a positive locking element is provided in a simple manner, with which the securing element can be indirectly brought into engagement with the shaft.
Weiterhin bevorzugt ragt die Rastnase ausgehend von dem Umfangsabschnitt nach radial innen und steht über eine von dem Drehkörper abgewandte Stirnfläche des Arretierungselements mit einem Verbreiterungsabschnitt axial über. Hierdurch ergibt sich eine breite Abstützung in Umfangrichtung des Arretierungselements in der Längsnut der Welle.Furthermore, the latching lug preferably projects radially inwards starting from the peripheral section and projects axially beyond a front face of the latching element facing away from the rotary element with a widening section. This results in a broad support in the circumferential direction of the locking element in the longitudinal groove of the shaft.
Bevorzugt ist das Sicherungselement als radial dehnbarer Sprengring mit einem Umfangsspalt ausgebildet, wobei das Arretierungselement formschlüssig in den Umfangsspalt eingreift. Hierdurch kann in vorteilhafter Weise das Sicherungselement als normierter und leicht verfügbarer Sprengring bereitgestellt werden.Preferably, the securing element is designed as a radially expandable snap ring with a circumferential gap, wherein the locking element engages positively in the circumferential gap. In this way, the securing element can be provided as a standardized and easily available snap ring in an advantageous manner.
Bevorzugt greift das Arretierungselement durch den Umfangsspalt hindurch in die Längsnut der Welle formschlüssig ein. Hierdurch ist es nicht erforderlich Veränderungen beziehungsweise Anpassungen an dem Sicherungselement vorzunehmen.Preferably, the locking element engages through the circumferential gap in the longitudinal groove of the shaft form-fitting manner. As a result, it is not necessary to make changes or adjustments to the fuse element.
In konkreter Ausgestaltung handelt es sich bei dem Drehkörper um einen Synchronkörper einer Drehzahlsynchronisierungseinrichtung. Hierdurch kann in vorteilhafter Weise das Verschleißverhalten an einer Drehzahlsynchronisierungseinrichtung verbessert werden.In a concrete embodiment, the rotary body is a synchronous body of a rotational speed synchronization device. As a result, the wear behavior at a rotational speed synchronization device can be improved in an advantageous manner.
Hierbei handelt es sich bevorzugt bei der Welle um eine in einem Gehäuse drehbar gelagerte Vorgelegewelle einer Getriebeeinheit, wobei das Sicherungselement und das Arretierungselement auf der dem angetriebenen Ende der Vorgelegewelle zugewandten Seite des Drehkörpers angeordnet sind. Hierdurch kann in vorteilhafter Weise das Sicherungselement mit handelsüblichen Montagewerkzeugen montiert werden. Weiter kann in vorteilhafter Weise das Arretierungselement ohne Montagewerkzeug montiert werden.These are preferably in the shaft to a rotatably mounted in a housing countershaft of a gear unit, wherein the securing element and the locking element on the driven end of the countershaft facing side of the rotary body are arranged. As a result, the securing element can be mounted with commercially available assembly tools in an advantageous manner. Further, the locking element can be mounted without an assembly tool in an advantageous manner.
