Description
Bei Nadellagern bekannter Bauart besteht der Laufring aus einem Blechmantel, dessen Seiten so umgewalzt sind, daß sie die Nadeln an ihren Stirnflächen umgreifen und damit gegen Herausfallen sichern. Diese Nadellager haben den Nachteil, daß die Nadeln keine achsparallele Führung haben.In needle roller bearings of known designs, the raceway consists of a sheet metal jacket, the sides of which are rolled over so that they grip the needles at their end faces and thus secure against falling out. These needle bearings have the disadvantage that the Needles do not have an axially parallel guide.
Diesen Mangel zu beseitigen bezweckt die vorliegende Erfindung, und es wird dies dadurch erreicht, daß das Nadellager gebildet wird aus einem besonderen Käfig, in welchem die Nadelrollen gehalten und achsparallel geführt werden, und dieser Nadelkäfig in einem aus Blech oder dünnem Rohr bestehenden Laufring liegt und von diesem seitlich gehalten und geführt wird und mit dem Nadelkäfig zusammen ein einheitliches Lagersystem- bildet.The present invention aims to remedy this deficiency, and this is achieved in that the needle bearing is formed from a special one Cage in which the needle rollers are held and guided axially parallel, and this needle cage lies in a race made of sheet metal or thin tube and is held and guided laterally by this and together with the needle cage forms a uniform storage system.
In der Zeichnung ist der Gegenstand der Erfindung an einem Ausführungsbeispiel erläutert. Es zeigt Abb. i einen Längsschnitt durch das Lager, Abb. 2 einen Teilschnitt durch den Laufring. Das Nadellager wird gebildet aus dem Außenlaufring i, der aus einem Blechmantel besteht und an seinen Enden 2° und 26 seitlich umgewalzt ist und so ein U-förmiges Profil bildet.In the drawing, the subject matter of the invention is based on an exemplary embodiment explained. It shows Fig. I a longitudinal section through the bearing, Fig. 2 a partial section through the raceway. The needle bearing is formed from the outer race i, which consists of consists of a sheet metal jacket and is rolled over at its ends 2 ° and 26 and so forms a U-shaped profile.
Die Nadelrollen 3 werden durch den Käfig ,4 gehalten, in welchem sie in Gruppen aneinanderliegen und durch einzelne Stege voneinander getrennt werden. Diese Trennungsstege übernehmen die achsparallele Führung der Nadelrollen. Um die Nadeln gegen Herausfallen zu sichern, werden sie durch den Nadelkäfig an ihren Enden seitlich umfaßt.The needle rollers 3 are held by the cage 4, in which they lie next to one another in groups and are separated from one another by individual webs. These separation bars take over the axially parallel guidance of the needle rollers. To the To secure needles against falling out, they are secured by the needle cage at their ends laterally embraced.
Wie die Abb. 2 erkennen läßt, kann bei dein Außenlaufring i die eine Seite 2a bei der Fertigung bereits vorher umgewalzt werden, während die zweite Seite 26 zunächst offen bleibt.As can be seen in Fig. 2, one of your outer race i can Side 2a is already rolled over during production, while the second side 26 initially remains open.
Nachdem der Nadelkäfig mit den Nadeln in den Außenlaufring seitlich eingeschoben worden ist, wird auch das Ende 26 des Laufringes umgewalzt, und damit bildet dann der Laufring mit dem Käfig und den Nadelrollen ein einheitliches komplettes Lagerelement.After the needle cage with the needles in the outer race laterally has been inserted, the end 26 of the race is rolled over, and thus The race then forms a complete unit with the cage and the needle rollers Bearing element.
Der Laufring i wird aus Blech oder dünnem Rohr gewalzt oder gezogen. Er hat nur noch die Aufgabe, den Käfig, in dein die Nadelrollen gehalten und achsparallel geführt sind, zu halten, um so mit diesem ein in sich geschlossenes System zu bilden, wodurch ein leichter Ein- und Ausbau der Lagerteile gewährleistet wird.The race i is rolled or drawn from sheet metal or thin pipe. He only has the task of holding the cage in which the needle rollers are kept and axially parallel are to be held in order to form a self-contained system with it, whereby an easy installation and removal of the bearing parts is guaranteed.
Ein besonderer Vorteil dieser Konstruktion gegenüber bekannten Nadellagern mit Laufringen, die aus einem Blechmantel mit umgebördelten Enden bestehen, liegt darin, daß die Enden nur einmal um 9o° nach innen gezogen werden und hierbei die Nadel selbst nicht unterfassen. Die Verformung des Laufringes ist damit wesentlich erleichtert, was für die Herstellung von Bedeutung ist.A particular advantage of this design over known needle roller bearings with races, which consist of a sheet metal jacket with flanged ends, lies in that the ends are pulled inwards only once by 90 ° and in this case the Do not reach under the needle itself. The deformation of the race is therefore essential facilitates what is important for the production.
