Description
NadellagerNeedle roller bearings
Die Neuerung betrifft Nadellager mit einem Außenring aus Blech oder Rohr und einem die Nadeln in Taschen achsparallel führenden sowie zur Lagerachse hin haltenden Käfigo Derartige Nadellager e auch als Nadelhülse oder Nadelbüchse bezeichnet, werden in großem Umfang anstelle von Gleitlagerbüchsen verwendet, denen sie in vieler Hinsicht überlegen sind.The innovation relates to needle bearing having an outer ring of sheet metal or tube and the needles in pockets axially parallel leading and to the bearing axis toward retaining cage o Such needle bearing e referred to as a needle sleeve or a needle bush, are widely used in place of plain bearing bushings used, which they in many ways are superior.
Bei einigen bekannten Ausführungen solcher Nadellager werden die Nadeln in axialer Richtung durch Seitenringe des Käfigs geführt. Um dabei zu verhüten, daß sich die Nadelenden in die Käfigseltenringe einbohren oder auf die Seitenringe hinaufklettern, müssen die Seitenringe entsprechend gestaltet und behandelt werden, was den Käfig in der Herstellung verteuert. Bei einer anderen bekannten Ausführung stützen sich die Nadelenden an umgebördelten Rändern des Außenringes ab. Dabei muß entweder der eine Rand des Außenringes nach dem Einsetzen des Käfigs und der Nadeln umgelegt oder die Nadeln von innen in die Käfigtaschen eingeschnappt werden o In dem einen Fall muß der betreffende Rand des Außenringes bei dessen Härtung weich gehalten werden und im anderen Fall müssen die HaiteSchikanen des Käfigs eine Ausbildung erhalten, die das Einschnappen der Nadeln in die Käfigtaschen zuläßto Beides hat Nachtelle, die Lagerstörungen verursachen können0 In some known designs of such needle roller bearings, the needles are guided in the axial direction through side rings of the cage. In order to prevent the needle ends from boring into the cage rings or climbing up onto the side rings, the side rings must be designed and treated accordingly, which makes the cage more expensive to manufacture. In another known embodiment, the needle ends are supported on flanged edges of the outer ring. Here, either the one edge of the outer ring after insertion of the cage and of the needles must be folded or the needles are snapped from the inside in the cage pockets o in which the edge in question must of the outer ring can be kept soft during its curing a case and in the other case have the Haite chicanes of the cage receive a training that allows the needles to snap into the cage pockets o Both have drawbacks that can cause storage problems 0
Bei dem Gegenstand der Neuerung sind die geschilderten Nachteile vermieden und eine preisgünstige Fertigung und Montage des Lagers dadurch erreicht worden, daß in den Außenring wenigstens einenends ein ring- bzw. scheibenförmiger Körper aus Kunststoff, z.B# aus glasfaserverstärktem. Polyamid, selbsthaltend eingebracht ist, der eine ebene Ringfläche für den Stirnflächenanlauf der Nadeln sowie eine versetzt dazu liegende zweite Ringfläche für den Stirnflächenanlauf des Käfigs besitzt. Nach einem weiteren NeuerungsmerkmalIn the subject of the innovation, the disadvantages described are avoided and an inexpensive production and assembly of the bearing has been achieved that in the outer ring at least one end of an annular or disc-shaped body made of plastic, for example # made of glass fiber reinforced. Polyamide, is introduced in a self-retaining manner, which has a flat annular surface for the end face contact of the needles and a second annular surface, offset thereto, for the end face contact of the cage.

ist der als randlose zylindrische Hülse ausgebildete Käfig radial auf einer Schulter des oder der Kunststoffkörper geführt, deren zylindrische Fläche die beiden versetzt zueinander liegenden ebenen Ringflächen verbindet»is designed as a rimless cylindrical sleeve Cage guided radially on a shoulder of the plastic body or bodies, the cylindrical surface of which connects the two offset flat ring surfaces »
Die Zeichnung veranschaulicht vier Ausführungsbeispiele neuerungsgemäß gestalteter Nadellager, jeweils in einem Teilaxialschnitt.The drawing illustrates four exemplary embodiments of needle roller bearings designed according to the invention, each in a partial axial section.
Nach Figo 1 ist der aus einem gezogenen Blechtopf gefertigte Außenring 1 einenends mit einem beim Ausstanzen des Topfbodens erzeugten festen Bord versehen und anderenends mit einer keilförmigen Ringnut 3» Der Käfig 4 ist eine glatte zylindrische Hülse mit eingestanzten. Taschen 5 zur Aufnahme und achsparallelen Führung der Nadeln 60 Der Käfig liegt mit seinem Umfang innerhalb des Rollenteilkreises und die Taschen 5 besitzen in ümfangsrichtung eine Breite, die etwas kleiner ist als der Durchmesser der Nadeln. Der Käfig kann aus einem Rohrabschnitt oder auch aus einem flachen, aufgerollten und an den Enden zusammengeschweißten Blechstreifen wirtschaftlich hergestellt werden.According to Figo 1, the outer ring 1 made of a drawn tin pot is provided at one end with a solid rim produced when the pot bottom is punched out and at the other end with a wedge-shaped annular groove 3 »The cage 4 is a smooth, cylindrical sleeve with punched in. Pockets 5 for receiving and axially parallel guidance of the needles 6 0 The circumference of the cage lies within the pitch circle and the pockets 5 have a width in the circumferential direction that is slightly smaller than the diameter of the needles. The cage can be manufactured economically from a pipe section or from a flat, rolled-up sheet metal strip welded together at the ends.
Nachdem der Außenring t auf den mit Nadeln 6 gefüllten Käfig 4 aufgeschoben worden ist, wird in das offene Außenringende ein Kunststoffring 7 eingedrückt, der mit seiner Randleiste 8 in die Ringnut 3 einrastet. Der im Querschnitt winkelförmig gestaltete, vorzugsweise aus glasfaserverstärktem Polyamid hergestellte Ring 7 weist eine ebene Ringfläche 9 und eine versetzt dazu liegende weitere ebene Ringfläche 10 auf, die beide durch eine zylindrische Fläche 11 verbunden sind. Die Ringfläche dient dem Stirnflächenanlauf der Nadeln, während die Ringfläche 10 dem Käfig k als axiale Begrenzung dient und die zylindrische Fläche 11 der radialen Käfigführung.After the outer ring t has been pushed onto the cage 4 filled with needles 6, a plastic ring 7 is pressed into the open end of the outer ring and its rim 8 engages in the annular groove 3. The ring 7, which is angular in cross section and is preferably made of glass fiber reinforced polyamide, has a flat ring surface 9 and a further flat ring surface 10 offset thereto, both of which are connected by a cylindrical surface 11. The annular surface serves as the end face of the needles, while the annular surface 10 serves as an axial limit for the cage k and the cylindrical surface 11 serves as the radial cage guide.
