KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft ein Rollenlager mit Rollenkäfig, dessen eigentümliche Bauart und Anordnung für getrenntständige Rollen die gesicherte Führung im Verhältnis zu dem inneren und äußeren Laufringe mitbedingt. Gemäß der Erfindung ist der Rollenkäfig zur Aufnahme zweier Gruppen von Rollen hergerichtet, derart, daß die die eine Gruppe bildenden Käfigrollen, sofern sie an durchgehenden, ίο die Seitenringe des Käfigs verbindenden Stehbolzen la.ufen, dem Käfig die Umlaufführung geben, während die anderen Freilaufrollen unter sich und gegen jene Käfigrollen durch vorzugsweise plattenförmige Zwischenstücke, die als Versteifungsglieder die Seitenringe des Käfigs von Seite zu Seite verbinden, parallel gerichtet und getrennt gehalten werden.The invention relates to a roller bearing with Roller cage, its peculiar design and arrangement for separate roles the secured guidance in relation to the inner and outer races. According to the invention, the roller cage is designed to accommodate two groups of rollers, in such a way that the cage rollers forming a group, if they are attached to continuous, ίο the stud bolts connecting the side rings of the cage run, the cage the circumferential guide give, while the other free-wheeling rollers among themselves and against those cage rollers through preferably plate-shaped spacers, which act as stiffening members, the side rings of the Connect cage from side to side, parallel and kept separate.
Der Seitenschub wird bei dieser Anordnung des Rollenkäfigs von den Stirnwangen des inneren und äußeren Laufringes zweckmäßig mittels Kugellagerung aufgenommen.With this arrangement of the roller cage, the sideshift is caused by the front cheeks of the inner and outer race suitably added by means of ball bearings.
Auf der Zeichnung ist:On the drawing is:
Fig. ι eine Ansicht eines gemäß der Neuerung eingerichteten Rollenlagers, zur Hälfte aufgedeckt gezeichnet, indem der Seitenring des Käfigs teilweise fortgelassen ist,Fig. Ι a view of a roller bearing set up according to the innovation, half drawn face up, with the side ring of the cage partially omitted,
Fig. 2 eine Querschnittfigur zu Fig. 1.FIG. 2 shows a cross-sectional figure relating to FIG. 1.
Fig. 3 ist eine Schnittdarstellung der hauptsächlichen Käfigteile, in etwas kleinerem Maßstäbe aus Fig. 2 herausgezeichnet.Fig. 3 is a sectional view of the main cage parts, on a slightly smaller scale drawn out from FIG.
Fig. 4 stellt im Schnitt einen Teil einer anderen Ausführungsform des Lagers dar.Fig. 4 shows in section a part of another embodiment of the bearing.
Zwischen dem inneren Laufringe u und dem äußeren Laufringe v, die zylindrische Laufflächen besitzen, sind die Rollen r, w eingebaut, welche von dem Käfig a, a (Fig. 3) getragen werden. Der Käfig hat als Verbindungsmittel seiner Seitenringe die Zapfen c und die Zwischenstücke s.Between the inner races u and the outer races v, which have cylindrical running surfaces, the rollers r, w are installed, which are carried by the cage a, a (Fig. 3). The cage has the pins c and the spacers s as the connecting means of its side rings.
Die Rollen sind in zwei Gruppen vorhanden, und zwar sind die mit w bezeichneten in ihrer Achsenrichtung durchbohrt, während die anderen Rollen r voll sind. Die Rollen w sind auf den Zapfen c zwischen den Käfigseitenringen α, α gelagert; sie brauchen nur in verhältnismäßig geringer Anzahl (z. B. fünf oder ' drei) rings um den Lagerkranz verteilt, angeordnet zu sein, da sie vornehmlich dem Zwecke dienen, dem Rollenkäfig eine Führung zu bieten, damit seine Seitenringe möglichst ohne Reibung (d. h. mit Spielraum) an den entsprechend gleichachsig ausgedrehten Laufringstirnseiten laufen. Unter Bestimmung eines den Rollen einen gewissen Spielraum übriglassenden gegenseitigen Abstandes sind zwisehen den Käfigseitenringen a die Zwischenstücke s so befestigt, daß sie die Rollen voneinander getrennt halten. Man bemerkt, daß die Rollen w eine Außenberührung an den Zwischenstücken s weder nach der einen noch nach der anderen Richtung haben, gleichzeitig aber — wofern eine etwas lose Lagerung an den Zapfen c vorausgesetzt ist — eine Führung von den Wangen der Käfigseiten α (die stirnseitig wiederum von den Laufringen u, ν selbst geführt werden) erhalten. Die andere Gruppe von Rollen r wird an gegenseitiger Berührung durch die Zwischenstücke s gehindert; an diesen selbst ist, wenn überhaupt die Anlage stattfindet, immer nur eine einseitige Berührung mit geringer Reibung möglich. Beim Durchgange jeder RolleThe rolls are in two groups, namely those marked w are pierced in their axial direction, while the other rolls r are full. The rollers w are mounted on the pin c between the cage side rings α, α ; they only need to be distributed in a relatively small number (e.g. five or three) around the bearing ring, since they primarily serve the purpose of providing the roller cage with a guide so that its side rings are as free as possible from friction (i.e. with Clearance) run on the correspondingly coaxially machined face of the race ring. By determining a mutual distance that leaves a certain margin for the rollers, the spacers s are fastened between the cage side rings a in such a way that they keep the rollers separated from one another. One notices that the rollers w have external contact with the intermediate pieces s neither in one direction nor in the other, but at the same time - provided that a somewhat loose mounting on the pin c is assumed - a guide from the cheeks of the cage sides α (the end face are in turn guided by the races u, ν themselves). The other group of rollers r is prevented from touching one another by the intermediate pieces s; on these themselves, if the contact takes place at all, only one-sided contact with little friction is possible. When going through every role
durch die entlastete Stelle des Rollenlagers kann eine Einstellung und Einrichtung auf die Freilauflage von selbst erfolgen. Dabei wirken die zweckmäßig plattenförmigen Zwischenstücke s als hilfsweise Führungs- und Einstellmittel, während die stirnseitige Führung anderseits durch die Käfigseitenringe α, α bedingt wird. Die Befestigung der Zwischenstücke s an den Seitenringen α kann in beliebiger Art, z. B. durch Nietvorsprünge o. dgl., bewerkstelligt werden.Due to the relieved point of the roller bearing, an adjustment and set-up on the free-wheel support can be carried out by itself. The expedient plate-shaped spacers s act as an auxiliary guide and adjustment means, while the frontal guidance is on the other hand caused by the cage side rings α, α . The attachment of the spacers s to the side rings α can be done in any way, for. B. by rivet projections o. The like., Can be accomplished.
Etwaiger Seitendruck wird mittels der Käfigseitenringe a, a, die durch die Zwischenglieder c, s eine widerstandsfähige Versteifung und Verbindung besitzen, durch die Laufringwangen aufgenommen. Infolge der Einlagerung der Ringe α, α des Käfigs in die Laufringseiten wird die innere Laufringbahn auf beiden Seiten völlig gedeckt und gegen Eindringen von Fremdkörpern gesichert. Zwischen den Seitenringen α und den Stirnflächen der Laufringe u, ν können Kugellager p, g angeordnet werden, wie aus Fig. 4 ersichtlich ist.Any side pressure is absorbed by the race ring cheeks by means of the cage side rings a, a, which have a resistant reinforcement and connection due to the intermediate links c, s. As a result of the inclusion of the rings α, α of the cage in the raceway sides, the inner raceway is completely covered on both sides and secured against the ingress of foreign bodies. Ball bearings p, g can be arranged between the side rings α and the end faces of the races u, ν , as can be seen from FIG.
