Abstract
Lagerung und axiale Fixierung eines Zahnrades (1) auf einem Lagerhals (2) einer Gehäusewand (3) über mindestens ein Lager (6, 7), wobei das Zahnrad (1) eine Tragscheibe (1b) und eine Nabe (1c) aufweist, wobei das mindestens eine Lager (6, 7) durch ein Sicherungselement (9) auf dem Lagerhals (2) fixierbar ist, wobei in der Tragscheibe (1b) mindestens ein Durchbruch (10, 11) vorgesehen ist, dadurch gekennzeichnet, dass das Sicherungselement (9) über den mindestens einen Durchbruch (10) montiert ist, wobei auf der dem Lagerhals (2) zugewandten Seite der Tragscheibe (1b) oder der Nabe (1c) im Bereich des mindestens einen Durchbruches (10) ein Absatz (12) als Montagehilfe für den Sicherungsring (9) angeordnet ist.Bearing and axial fixation of a gear (1) on a bearing neck (2) of a housing wall (3) via at least one bearing (6, 7), wherein the gear (1) has a support disc (1b) and a hub (1c), wherein the at least one bearing (6, 7) can be fixed on the bearing neck (2) by a securing element (9), wherein at least one opening (10, 11) is provided in the support disk (1b), characterized in that the securing element (9 ) is mounted on the at least one opening (10), wherein on the bearing neck (2) facing side of the support disk (1b) or the hub (1c) in the region of the at least one opening (10) has a shoulder (12) as an assembly aid for the retaining ring (9) is arranged.
Description
Die Erfindung betrifft die Lagerung und axiale Fixierung eines Zahnrades nach dem Oberbegriff des Patentanspruches 1.The invention relates to the storage and axial fixation of a gear according to the preamble of
Durch die
Die
Ausgehend von diesem Stand der Technik, ist es Aufgabe der Erfindung, eine Lagerung und axiale Fixierung eines Zahnrades auch bei beschränkten Einbaubedingungen, insbesondere bei geringem axialen Bauraum vorzuschlagen.Based on this prior art, it is an object of the invention to provide a storage and axial fixation of a gear even with limited installation conditions, especially with a small axial space.
Die Aufgabe der Erfindung wird durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The object of the invention is solved by the features of
Erfindungsgemäß ist vorgesehen, dass das Lager in axialer Richtung durch ein Sicherungselement fixiert ist, welches durch eine in der Tragscheibe des Zahnrades angeordnete Montageöffnung zugänglich ist. Aufgrund der als Durchbruch ausgebildeten Montageöffnung ist es möglich, das Sicherungselement, vorzugsweise einen Sicherungsring von außen mittels einer Montagezange, welche durch die Montageöffnung hindurch greift, zu greifen und zu montieren. Damit wird der Vorteil einer extrem kurzen axialen Bauweise erreicht.According to the invention it is provided that the bearing is fixed in the axial direction by a securing element, which is accessible through a arranged in the support plate of the gear mounting hole. Due to the opening formed as a breakthrough mounting aperture, it is possible, the securing element, preferably a locking ring from the outside by means of an assembly tool, which engages through the mounting hole, grab and assemble. This achieves the advantage of an extremely short axial design.
Nach einer bevorzugten Ausführungsform ist das Zahnrad über zwei Wälzlager auf dem Lagerhals gelagert, welcher in eine Stufenbohrung des Zahnrades hineinragt, sodass sich die beiden Wälzlager etwa im Bereich der Breite der Verzahnung befinden. Damit wird eine annährend symmetrische Lagerung des Zahnrades erreicht, was sich vorteilhaft auf den Zahneingriff und das Verzahnungsgeräusch auswirkt. Das Zahnrad kann somit unmittelbar neben der Gehäusewand gelagert und axial gesichert werden.According to a preferred embodiment, the gear is mounted on the bearing neck via two roller bearings, which projects into a stepped bore of the toothed wheel, so that the two roller bearings are located approximately in the region of the width of the toothing. This achieves an approximately symmetrical mounting of the toothed wheel, which has an advantageous effect on the tooth engagement and the toothing noise. The gear can thus be stored directly next to the housing wall and secured axially.
Nach einer weiteren bevorzugten Ausführungsform ist an der Tragscheibe im Bereich der Montageöffnung und auf der dem Sicherungselement zugewandten Seite ein umlaufender Absatz vorgesehen, welcher einen dem Innendurchmesser des Sicherungsringes entsprechenden Außendurchmesser aufweist. Dadurch ist es möglich, den Sicherungsring bei der Montage zunächst auf dem Absatz der Tragscheibe (oder auch der Nabe) vorzupositionieren und anschließend – nach der Montage des Zahnrades – in die entsprechende Nut im Lagerhals einzusetzen. Vorteilhafterweise ist eine weitere Montageöffnung vorgesehen, welche eine Kontrolle der Montage des Sicherungsringes durch Sichtprüfung erlaubt.According to a further preferred embodiment, a circumferential shoulder is provided on the support disk in the region of the mounting opening and on the side facing the securing element, which has an outer diameter corresponding to the inner diameter of the securing ring. This makes it possible to pre-position the locking ring during assembly, first on the shoulder of the support disc (or the hub) and then - after the installation of the gear - to use in the corresponding groove in the bearing neck. Advantageously, a further mounting opening is provided, which allows a control of the mounting of the retaining ring by visual inspection.
Nach einer weiteren bevorzugten Ausführungsform ist das Zahnrad mit seiner Nabe auf einer Welle angeordnet, welche von einer Längsbohrung des Lagerhalses aufgenommen wird. Die Welle kann An- oder Abtriebswelle des Zahnrades sein, welches vorzugsweise mit mindestens einem weiteren Zahnrad in Eingriff steht und somit Teil eines Getriebes ist.According to a further preferred embodiment, the gear is arranged with its hub on a shaft which is received by a longitudinal bore of the bearing neck. The shaft may be input or output shaft of the gear, which is preferably engaged with at least one other gear and thus is part of a transmission.
