H Zwei- bzw. dreiteiliges, ein- oder doppel-H Two or three-part, one or double
reihiges selbsthaltendes Kugellager aus Stahl, bestehend aus spanlos verformten Kugellager-Laufringen n Kugellager, bestehend außer den Kugeln aus nur zwei Laufringen mit winkelförmigem Querschnitt, sind bereits bekannt geworden, so z.B. DT-PE.row self-retaining ball bearing made of steel, consisting of non-cutting deformed ball bearing races n ball bearings, consisting of only the balls two race rings with an angular cross-section are already known, so e.g. DT-PE.
Xr. 192 8580 Die Laufringe dieser bekannten Kugellager sind aus massivem Material, meist aus Kunststoff, hergestellt oder im Fließpreßverfahren ad. dergl. gefertigt und benötigen vielfach zu ihrem Zusammenhalt besondere hinrichtungen. Derartige Kugellager erfordern in ihrer Herstellung einen erheblichen Aufwand und sind wegen ihrer hohen Herstellungskosten bei großen Bedarfszahlen von Lagern einfacher Bauweise nur unvorteilhaft einsetzbar0 Man hat deshalb auch bereits Kugellager entwickelt, deren Laufringe aus Flachmaterial (z.Bo Bandstahl) bei spanloser Verformung hergestellt werden, z.B. DT-GM 1 996 774, 7 310 449, jedoch ist deren Herstellung außerordentlich kompliziert und meist auch nur für Spezialzwecke gedacht I)ie vorgenannten und weitere Nachteile zu vermeiden, ist Aufgabe vorliegender Neuerunb, deren Lösung dadurch gekennzeichnet ist, daß bei zweiteiligen einreihigen Kugellagern mit winkelförmigem wuerschnitt die aui'rine spaiilos ver-formt sind und nierbei der Innenlaufring einen nach außen strebenden flansch aufweist und die Kugellaufbahn im zylindrischen Teil des innenlaufringes eingerollt oder eingepreßt hinterschnitten ist; sowie der spanlos verformte Außenlaufring einen nach innen strebenden Flansch aufweist und die Kugellaufbahn im zylindrischen Teil des Außenlaufringes ebenfalls eingerollt oder eingepreßt hinterschnitten ist.Xr. 192 8580 The races of these well-known ball bearings are made of solid Material, mostly made of plastic, or made using an extrusion process ad. the like. Manufactured and often require special executions to keep them together. Such ball bearings require considerable effort and expense in their manufacture are simpler because of their high manufacturing costs when large numbers of bearings are required Construction method can only be used unfavorably 0 Ball bearings have therefore already been developed whose races are made of flat material (e.g. steel strip) with non-cutting deformation e.g. DT-GM 1 996 774, 7 310 449, but their production is extraordinary complicated and mostly only intended for special purposes I) the aforementioned and others Avoiding disadvantages is the task of the present new company and thereby solving them is characterized in that with two-part single row ball bearings with angular the aui'rine spaiilos are deformed and the inner race ring is missing has outwardly striving flange and the ball raceway in the cylindrical part the inner race is rolled up or pressed in undercut; as well as the chipless deformed outer race has an inwardly striving flange and the ball raceway also rolled or pressed undercut in the cylindrical part of the outer race is.
Eine weitere Lösung der gestellten Aufgabe besteht in der Herstellung eines dreitaligen doppelreihigen Kugellagers mit winkelförmigem Querschnitt der auBenlaufringe, wobei der einstückige vorzugsweise spanlos hergestellte Innenlaufring eine nach außen zeigende mittlere rundumlaufende Sickenwulst aufweist, in deren hinterschnittenen Kugellaufflächen die Kugeln laufen, über die von den beiden Stirnseiten her je ein Außenlafring aufgedrückt ist.Another solution to the problem is the production of a three-point, double-row ball bearing with an angular cross-section of the outer races, the one-piece inner race, preferably produced without cutting an outward-facing central, all-round bead having, the balls run in their undercut ball bearing surfaces, over which the An outer ring is pressed on each of the two end faces.
Noch eine weitere MöDlichkeit der herstellung eines dreiteiligen doppelreihigen Kugellagers mit winkelförmigem Querschnitt der innenlaufringe besteht darin, daß der einstückige vorzugsweise spanlos hergestellte außenlaufring eine mittlere rundumlaufende, nach innen zeigende Sickenwulst aufweist, in deren hinterschnittenen Kugellaufbahnen die Kugeln laufen, in die von beiden Stirnseiten her je ein innenlaufring eingedrückt ist.Yet another way of making a three-piece double-row Ball bearing with an angular cross-section of the inner races consists in that the one-piece, preferably non-cutting manufactured outer race has a central all-round, has inwardly pointing bead in the undercut ball tracks the balls run into which an inner race ring is pressed from both ends is.
Wie die Neuerung im einzelnen ausgeführt sein kann, ergibt sich aus der nachfolgenden Beschreibung und den Zeichnungen, in denen Ausführungs beispiele zum Teil schematisch dargestellt sind, und ear zeigen 2igo 1 einen Innenlaufring-eines einreihigen Kugellagers im Mittelquerschnitt, Fig. 2 einen Außenlaufring passend zu tigo 1 Fi. 3.ein komplettes einreihiges Kugellager gem. ig. 1 + 2, Fig. 4 einen einstückigen Innenlaufring eines doppelreihigen Kugellagers mit nach außen tragenuer Sickenwulst, Pig, 5 einen Mittelquerschnitt eines der beiden Außenlaufringe passend zu Fig. 4, Fig. 6 ein komplettes doppelreShiges Kugellager gem. Fig. 4 u. 5, Fig. 7 einen einstückigen Außenlaufring eines doppelreihigen Kugellagers mit nach innen ragener Sickenwulst, Fig. 8 einen Mittelquerschnitt eines der beiden lnnenlaufringe passend zu Fig. 7, Fig. 9 ein komplettes doppelreihiges Kugellager gem. Fig. 7 u. 8.How the innovation can be carried out in detail emerges from the following description and drawings in which execution examples are partly shown schematically, and ear 2igo 1 show an inner race-one single-row ball bearing in the central cross-section, Fig. 2 an outer race ring fitting to tigo 1 Fi. 3. a complete single row ball bearing according to. 1 + 2, Fig. 4 a one-piece inner race of a double row ball bearing with outward bearing Beading, Pig, 5 shows a central cross-section of one of the two outer races 4, 6, a complete double-braced ball bearing according to FIGS. 5, Fig. 7 with a one-piece outer race of a double-row ball bearing inwardly protruding bead, FIG. 8 a central cross section of one of the two Inner races matching Fig. 7, Fig. 9 a complete double row ball bearing according to Fig. 7 and 8.
Zweck der neuerungsgemäßen Kugellager ist deren Laufringe aus lachmaterial, z.B. Bandstahl bei spanloser Verformung herzustellen, d.h. in sehr großen Stückzahlen sehr preiswert zu fertigen bei guter Qualität und hoher Präzision.The purpose of the ball bearings according to the innovation is their races made of laughing material, E.g. to produce steel strip with non-cutting deformation, i.e. in very large quantities very inexpensive to manufacture with good quality and high precision.
Demzufolge wird der Innenlaufring 1 (Fig. 1) eines einreihigen sugellagers bei spanloser Verformung mit winkelförmigem Querschnitt hergestellt aus Flachmaterial z.B. Bandstahl, mit nach außen strebendem Flansch 2 vollautomatisch in einem Folgewerkzeug, und zwar mit im zylinrischen Teil 3 des Innenlaufringe etwas hinterschnittener Kugellaufbahn 4. Hierzu passend wird ebenso der Außenlaufring 5 bei spanloser Verformung hergestellt aus Flachmaterial mit nach in- nen strebendem Blansch 6 mit ebenfalls im zylindrischen Teil 7 des Äußenlaufringes 5 etwas hinterschnittener Kugellaufbahn 8o Wesentlich ist hierbei, daß zwischen dem innen und außenlaufring 1 u. 5 BuZftspalte 9 vorgesehen sind, um ein Schleifen der Ringe 1 u0 5 aneinander zu vermeiden. Zwischen den beiden Kugellaufflächen 4 und 8 sind die Kugeln 10 angeordnet und ist in die mit Kugeln 10 gefüllte Kugellaufbahn 8 des außen laufringes 5 der Innenlaufring 1 eingepreßt. Das Material der beiden Laufringe gibt während dem momentanen und nur sehr kurzen Überdruck in soweit ohne Schaden nach und halten die drei Teile des Lagers, und zwar innen und Außenlaufring und die Kugeln durch die hinterschnittenen Kugellaufflächen zusammen.As a result, the inner race 1 (Fig. 1) becomes a single row sugar bearing in the case of non-cutting deformation with an angular cross-section made from flat material e.g. steel strip, with flange 2 extending outwards fully automatically in a subsequent tool, with a slightly undercut ball raceway in the cylindrical part 3 of the inner race 4. For this purpose, the outer race 5 is also produced with non-cutting deformation made of flat material with NEN aspiring Blansch 6 with also in the cylindrical part 7 of the outer race 5 slightly undercut ball race 8o It is essential that between the inner and outer race 1 and 5 BuZft gaps 9 are provided in order to avoid grinding of the rings 1 u0 5 against each other. Between the two ball running surfaces 4 and 8, the balls 10 are arranged and is in the with balls 10 filled ball raceway 8 of the outer race 5 of the inner race 1 pressed in. The material of the two races gives during the moment and only very brief overpressure in as far as without damage and hold the three parts of the bearing, namely the inner and outer race and the balls through the undercut Ball treads together.
Der gleiche Grundgedanke der Fertigung eines einreihigen Kugellagers gem. Etigo 1 - 3 ist aber auch anwendbar für die Fertigung von doppelreinigen Kugellagern gem. Fig. 4 - 6 , und zwar mit einem Innenlaufring 11 aus einem Stück, welches rohrartig gebildet ist mit einer nach außen zeigenden rundum laufenden Sickenwulst 12, die eingerollt, möglicherweise aber auch eingepreßt ist. Die aus senlaufringe 13 sind hierbei unter Zwischenfügung der Kugeln 14 von den beiden Stirnseiten her auf den gemeinsamen Innenlaufring 11 aufgedrücXt, wobei auch hier die Kugeln in hintersclmittenen Kugellaufbahnen laufen und Luftspalte an den möglichen Schleifflächen zwischen dem lnnenlaufring 11 und den hußenlaufringen 13 vorgesehen sind0 Darüber hinaus besteht die Möglichkeit der Fertigung eines dreiteiligen und doppelreihigen Ku- gellagers der gleichen Art wie vorbeschrieben mit dem Unterschied, daß ein einstückiger rohrartiser Außenlaufring 15 (Fig. 7) vorgesehen ist mit einer eingerollten oder eingepEeßten nach innen zeigenden Sickenwulst 16o Dieser einstückige Außenlaufring 15 weist beiderseits von der Sickenwulst 16 ebenfalls in den zylindrischen Teilen hinterschnittene Kugellaufbahnen auf, in denen die Kugeln 17 laufen und gehalten werden durch die jeweils beiderseits eingedrückten Innenlaufringe 18, die wie die vorbeschriebenen lnnenlaufringe 1 - 4 ebenfalls spanlos hergestellt werden.The same basic idea of manufacturing a single row ball bearing according to Etigo 1 - 3 can also be used for the production of double-clean ball bearings 4-6, with an inner race 11 made of one piece, which is tubular is formed with an outwardly pointing all around bead 12, which rolled up, but possibly also pressed in. The senlaufringe from 13 are here with the interposition of the balls 14 from the two end faces on the common inner race 11 pressed on, with the balls in the rear center Ball races run and air gaps on the possible grinding surfaces between the Inner race 11 and the sleeve races 13 are also provided the possibility of manufacturing a three-part and double-row plastic gellager of the same type as described above with the difference that a one-piece pipe artiser Outer race 15 (Fig. 7) is provided with a rolled or pressed-in inwardly pointing bead 16o This one-piece outer race ring 15 has on both sides from the bead 16 also undercut in the cylindrical parts ball tracks on, in which the balls 17 run and are held by each of the two sides indented inner races 18, which like the inner races 1 - 4 can also be produced without cutting.
Wesentlicher Zweck und Vorteil der vorbeschriebenen Kugellager ist, daß bei spanloser Fertigung sowohl ein- als auch doppelreihige Kugellager gefertigt werden, deren Innen- und Außenlaufringe des einreihigen Kugellagers auch bei doppelreihigen Kugellagern dieser Art Verwendung finden und damit eine sehr wirtschaftliche Fertigung gegeben ist Die Neuerung ist nicht auf die dargestellten Einzelheiten beschränkt, vielmehr auch abgeändert ausführbar, sofern nur die Erfindungsmerkmale zum Ausdruck kommen.The main purpose and advantage of the ball bearings described above is that both single-row and double-row ball bearings are manufactured in non-cutting production whose inner and outer races of the single-row ball bearing are also used in double-row Ball bearings of this type are used and thus a very economical production The innovation is not limited to the details shown, rather, it can also be carried out in modified form, provided that only the features of the invention are expressed come.
