Description
Die !Teuerung betrifft ein. Wälzlager, das aus mindestens einem Laufring und einer Anzahl, von Wälzkörpern, die gegen eine Laufbahn dieses Laufringes abrollen, besteht. Bei derartigen bekannten Wälzlagern ist die der Lauffläche gegenüberliegende Mantelfläche des Laufringes als glatte zylindrische Sitzfläche ausgebildet. Diese Sitzfläche des Laufringes wird bei der Herstellung auf ein ganz bestimmtes Durchmessermaß gebracht und muß beim Einbau des Lagers durch Einpressen in eine im Durchmesser genau darauf abgestimmte Bohrung (wenn es sich um einen Außenlaufring handelt) oder auf eine Welle (wenn es ein Innenlaufring ist), um damit den festen Sitz des Wälzlagers in axialer Richtung zu erreichen. Es bereitet keine Schwierigkeiten, bei der Wälzlagerherstellung die Durchmesser der Sitzflächen von Wälzlagerlaufringen in sehr engen Toleranzen zu halten, da es sich bei der Wälzlagerherstellung um eine Präzisionsfertigung handelt und die hierfür in Frage kommenden Fabriken aufgrund ihrer masehi-The! Inflation affects a. Rolling bearing made from at least a race and a number of rolling elements that roll against a raceway of this race, there is. In known roller bearings of this type, the outer surface of the raceway opposite the running surface is designed as a smooth cylindrical seat. These The seating surface of the race is brought to a very specific diameter during manufacture and must be used in Installation of the bearing by pressing it into a bore with a precisely matched diameter (if it is a Outer race) or on a shaft (if there is a Inner race) in order to achieve a tight fit of the rolling bearing in the axial direction. It doesn't prepare Difficulties in manufacturing the diameter of the bearings to keep the seating surfaces of rolling bearing races within very tight tolerances, as this is the case in rolling bearing manufacture is a precision manufacturing and the factories in question due to their masehi-
nellen Ausrüstung auf die Einhaltung sehr geringer Maßabweichungen eingerichtet sind. Wesentlich größere Schwierigkeiten "bereitet häufig in der Praxis die Einhaltung so geringer Durehmessertoleranzen an den Bauteilen, an denen die Wälzlager eingebaut werden sollen. Dies trifft insbesondere im Baumaschinen- und Landmaschinenbau zu, wo es sehr häufig herstellungstechnisch schwierig und immer in unerwünschtem Maße kostensteigernd wäre, wenn man die Sitzflächen für die Wälzlagerlaufringe in sehr engen Toleranzen herstellen müßte.nell equipment are set up to comply with very small dimensional deviations. Much larger Difficulties "often causes in practice compliance with such low diameter knife tolerances on the Components on which the rolling bearings are to be installed. This is especially true in construction machinery and Agricultural machinery too, where it is very often difficult to manufacture and always to an undesirable extent It would increase costs if the seat surfaces for the roller bearing races were manufactured in very tight tolerances would have to.
Nach der Neuerung wird zur Vermeidung dieser Nachteile vorgeschlagen, den Laufring an seiner der Wälzkörperlaufbahn abgekehrten Mantelfläche mit einer Terzahnung zu versehen. Eine solche Ausbildung ermöglicht es, wesentlich größere Durchmessertoleranzen der Gegensitzflache (in der Bohrung bzw. auf der Welle) hinnehmen zu können, ohne daß der feste Sitz des Laufringes gefährdet wäre. Die vorstehenden einzelnen Zähne an der Sitzfläche des Laufringes graben sich beim Einpressen des Laufringes in die glatte Oberfläche der Gegensitzfläche ein und gewährleisten immer dann einen festen Sitz des Laufringes, so lange in der Gehäusebohrung ein gewisses Durchmessermaß nicht überschritten bzw. auf der Welle nicht unterschritten wird.According to the innovation, it is proposed to avoid these disadvantages, the race on its the rolling element raceway to provide remote surface with a third serration. Such training enables it to be essential larger diameter tolerances of the opposing seat surface (in the bore or on the shaft) without endangering the tight fit of the race were. The protruding individual teeth on the seating surface of the raceway dig when being pressed in of the race in the smooth surface of the opposing seat and always ensure a tight fit of the race as long as a certain amount in the housing bore The diameter dimension is not exceeded or not undershot on the shaft.
In den Abbildungen sind zwei Ausführungsbeispiele der „■ · beschriebenen Feuerung dargestellt* Die Abbildungen 1 und 2 zeigen ein an sich handelsübliches Fadellager, das aus dem Außenlaufring 1, dem Innenlaufring 2 und den Fädeln 3 besteht. Die Fädeln 3 sind bei dem dargestellten Beispiel in einem Käfig 4 achsparallel geführt. Ein fester Bord 5 an dem einen Ende des Außenlaufringea T und eine nachträglich eingesetzte Verschlußscheibe 6 an dem anderen Ende verhindern, daß der Käfig 4 mit den Ha~ dein 3 axial aus dem Außenlaufring 1 herausrutschen kann. Der Innenlaufring 2 ist in seiner Bahrung mit einer "Verzahnung 7 versehen«The figures show two exemplary embodiments of the "■ · The firing described is shown * Figures 1 and 2 show a commercially available thread bearing, that from the outer race 1, the inner race 2 and the threads 3 consists. The threads 3 are in the one shown Example guided in a cage 4 axially parallel. A solid rim 5 at one end of the outer race a T and a subsequently inserted locking washer 6 at the other end prevent the cage 4 from having the Ha ~ your 3 can slip axially out of the outer race 1. The inner race 2 is in its form with a "toothing" 7 provided «
In den Abbildungen 3 und 4 ist die Anwendung der beschriebenen Heuerung bei einem Kugellager gezeigt. Das Lager besteht aus dem Außenlaufring 8, dem Innenlaufring 9 und den Kugeln 10, die in einem Käfig 11 untergebracht sind. In diesem Beispiel ist der Außenlaufring 8 über seinen ganzen Umfang mit einer Verzahnung 12 versehen.In Figures 3 and 4, the application of the hay described is shown in a ball bearing. The camp exists from the outer race 8, the inner race 9 and the balls 10, which are accommodated in a cage 11. In this example, the outer race 8 is provided with teeth 12 over its entire circumference.
In den beiden dargestellten Ausführungsformen ist jeweils nur einer der beiden Laufringe an seiner Sitzfläche mit einer Verzahnung versehen. Es ist jedoch auch Gegenstand der Feuerung und kann in sehr vielen Pällen zweckmäßig sein, die Sitzflächen beider Laufringe mit einer solchen Verzahnung zu versehen.In the two illustrated embodiments is in each case only one of the two races is provided with a toothing on its seat. However, it is also subject matter the furnace and can be useful in many cases, the seating surfaces of both races with such a toothing to provide.
