Abstract

The device has an omega circlip (3) for axially securing locking of a ball bearing (2) on a shaft (1), where the circlip is arranged between the shaft and a bearing. The circlip is mounted before the assembly of a bearing cover such that a borehole in the cover lockable by a screw cap for mounting the safety device is omitted, where the shaft is a side shaft of a stepless belt drive. An independent claim is also included for a method for mounting an axial locking device.

Description

Die vorliegende Erfindung betrifft eine axiale Sicherung einer Welle und des Lagers der Welle gemäß dem Oberbegriff des Patentanspruchs 1. Des weiteren betrifft die Erfindung ein Verfahren zur Montage der erfindungsgemäßen axialen Sicherung und des Lagers.The The present invention relates to an axial securing of a shaft and the bearing of the shaft according to the generic term of claim 1. Furthermore, the invention relates to a method for mounting the axial according to the invention Fuse and the bearing.

Nach dem Stand der Technik wird zur axialen Sicherung des Lagers, das üblicherweise als Kugellager ausgebildet ist, und der Welle ein Sprengring verwendet. Hierbei kann die Montage des Sprengringes auf der Welle nur durch eine Bohrung im Lagerdeckel erfolgen, welche in nachteiliger Weise nach der Sprengringmontage durch einen Verschlussdeckel, der üblicherweise als gummierter Stahldeckel ausgebildet ist, verschlossen werden muss.To The prior art is used for axial securing of the bearing, which is usually is designed as a ball bearing, and the shaft uses a snap ring. Here, the mounting of the snap ring on the shaft only by a bore in the bearing cap done, which disadvantageously after the snap ring assembly by a closure lid, which is usually is designed as a rubberized steel lid, to be closed got to.

Diese Vorgehensweise resultiert ist in nachteiliger Weise in hohen Bearbeitungs- und Herstellungskosten sowie in einem erhöhten Montageaufwand, da vor der Montage des Lagerdeckels auf der Welle, was durch Aufpressen über den Lagerinnenring erfolgt, die Kugellager in den Lagerdeckel montiert werden müssen, wobei anschließend der Sprengring durch eine Bohrung im Lagerdeckel auf der Seitenwelle montiert wird und die Bohrung mit dem Verschlussdeckel verschlossen wird.These Procedure results disadvantageously in high processing and manufacturing costs as well as in an increased assembly costs, as before the assembly of the bearing cap on the shaft, which by pressing on the Bearing inner ring takes place, the ball bearings mounted in the bearing cap Need to become, subsequently the snap ring through a hole in the bearing cap on the side shaft is mounted and the bore closed with the cap becomes.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine axiale Sicherung der Welle und des Lagers der Welle anzugeben, welche einfach zu montieren ist und dazu führt, dass die Herstellungskosten reduziert werden. Des weiteren soll ein Verfahren zur Montage der axialen Sicherung und des Lagers der Seitenwelle gemäß der Erfindung angegeben werden.Of the present invention is based on the object, an axial securing To specify the shaft and the bearing of the shaft, which is easy to assemble is and leads to that the manufacturing costs are reduced. Furthermore, should a method for mounting the axial securing and the bearing of Side shaft according to the invention be specified.

Diese Aufgabe wird für eine axiale Sicherung durch die Merkmale des Patentanspruchs 1 gelöst. Ein Verfahren zur Montage der erfindungsgemäßen axialen Sicherung und des Lagers ist Gegenstand des Patentanspruchs 2.These Task is for an axial securing solved by the features of claim 1. One Method for mounting the axial securing device according to the invention and of Warehouse is the subject of claim 2.

Demnach wird eine axiale Sicherung der Welle und des Lagers der Welle vorgeschlagen, welche einen „Omega"-Sprengring aufweist, der zwischen der Welle und dem Lager anordbar ist, wobei der „Omega"-Sprengring vor der Montage des Lagerdeckels montierbar ist, so dass eine mittels eines Verschlussdeckels verschließbare Bohrung zur Montage der axialen Sicherung im Lagerdeckel entfällt.Therefore an axial securing of the shaft and the bearing of the shaft is proposed, which has an "omega" snap ring, which can be arranged between the shaft and the bearing, wherein the "omega" snap ring before the Mounting the bearing cap is mountable, so that one by means of a cap lockable Bore to mount the axial securing in the bearing cap is eliminated.

Gemäß der Erfindung umfasst das Verfahren zur Montage der axialen Sicherung und des Lagers der Welle folgende Schritte:

  • – Einlegen des „Omega"-Sprengrings zwischen der Welle und dem Kugellager und Montieren des Kugellagers auf der Welle;
  • – Montieren der Welle im Lagerdeckel und
  • – Montieren des „Omega"-Sprengrings im Lagerdeckel.
According to the invention, the method for assembling the axial securing and the bearing of the shaft comprises the following steps:
  • - insert the "omega" snap ring between the shaft and the ball bearing and mount the ball bearing on the shaft;
  • - Mount the shaft in the bearing cap and
  • - Mount the "Omega" snap ring in the bearing cap.

Durch die erfindungsgemäße Konzeption wird neben der Montagevereinfachung eine signifikante Kostenersparnis durch den Entfall des Verschlussdeckels erzielt. Ferner entfällt durch den Entfall des Verschlussdeckels eine Leckagestelle.By the concept of the invention is in addition to the simplification of assembly, a significant cost savings achieved by the elimination of the cap. It also disappears the elimination of the cap a leak point.

Die Erfindung wird im Folgenden anhand der beigefügten Figuren beispielhaft näher erläutert.The The invention will be explained in more detail below by way of example with reference to the attached figures.

Es zeigen:It demonstrate:

2 ein Schnittansicht entlang der Linie F-F aus 1. 2 a sectional view taken along the line FF 1 ,

Gemäß der Erfindung und bezugnehmend auf 1 und 2 weist die axiale Sicherung der Welle 1 und des Lagers 2 der Welle 1 einen „Omega"-Sprengring 3 auf, der zwischen der Welle 1 und dem Lager 2 anordbar ist. Der „Omega"-Sprengring 3 ist in vorteilhafter Weise vor der Montage des Lagerdeckels 4 montierbar, so dass eine mittels eines Verschlussdeckels verschließbare Bohrung zur Montage des Sprengrings im Lagerdeckel 4 entfällt. In den 1 und 2 ist der Sprengring zur Sicherung des Lagers 2 auf der Welle 1 mit 5 bezeichnet.According to the invention and referring to 1 and 2 indicates the axial securing of the shaft 1 and the camp 2 the wave 1 an "omega" snap ring 3 on that between the shaft 1 and the camp 2 can be arranged. The "omega" snap ring 3 is in an advantageous manner before mounting the bearing cap 4 mountable, so that a sealable by means of a closure cover hole for mounting the snap ring in the bearing cap 4 eliminated. In the 1 and 2 is the snap ring to secure the bearing 2 on the wave 1 With 5 designated.

Selbstverständlich fällt auch jede konstruktive Ausbildung, insbesondere jede räumliche Anordnung der erfindungsgemäßen axialen Sicherung an sich sowie zueinander und soweit technisch sinnvoll, unter den Schutzumfang der vorliegenden Ansprüche, ohne die Funktion der axialen Sicherung, wie sie in den Ansprüchen angegeben ist, zu beeinflussen, auch wenn diese Ausbildungen nicht explizit in den Figuren oder in der Beschreibung dargestellt sind.Of course, too any constructive training, especially any spatial Arrangement of the axial according to the invention Fuse in itself and to each other and as far as technically reasonable, under the scope of the present claims, without the function of axial security, as indicated in the claims to influence, too if these trainings are not explicitly in the figures or in the Description are shown.
