Description
Kugelkäfig für Radialkugellager mit zur Lagerachse schrägen Druckrichtungen. Bei Radialkugellagern mit schrägen Druckrichtungen, z. B. doppelreihigen Kugellagern mit hohlkugeliger Außenlaufbahn, sind unter anderem Kugelkäfige verwendet worden, welche mit seitlich offenen, durch Bohrung oder Pressung hergestellten Kugeltaschen von hauptsächlich zylindrischer Form versehen sind, wobei der Boden der Taschen gewölbt oder kegelig ist. Bisher sind diese Taschen stets in der Weise ausgeführt worden, daß deren Achsen oder Mittellinien parallel zur Lagerachse liegen. Da aber in einem Lager mit zur Lagerachse schrägen Druckrichtungen die Drehung der Kugeln um eine Achse erfolgt, welche hauptsächlich senkrecht zu der Druckrichtung steht, somit einen Winkel mit der Achse der Kugeltasche bildet, so wird das Anliegen der Kugel sowohl an den Seitenwänden als an dem Boden der Tasche unsymmetrisch im Verhältnis zur Drehachse der Kugel. Dadurch wird die Rollbewegung der Kugel nachteilig beeinflußt und die Reibung erhöht.Ball cage for radial ball bearings with pressure directions inclined to the bearing axis. For radial ball bearings with oblique pressure directions, e.g. B. double row ball bearings with a spherical outer raceway, ball cages have been used, among other things, those with laterally open ball pockets made by drilling or pressing of mainly cylindrical shape, with the bottom of the pockets is curved or conical. So far, these pockets have always been designed in this way been that their axes or center lines parallel to the bearing axis lie. But since the rotation is in a bearing with pressure directions inclined to the bearing axis of the balls takes place around an axis which is mainly perpendicular to the direction of pressure stands, thus forms an angle with the axis of the ball pocket, the concern is of the ball both on the side walls and on the bottom of the pocket asymmetrically in the Relation to the axis of rotation of the ball. This makes the rolling motion of the ball disadvantageous affects and increases the friction.
Vorliegende Erfindung bezweckt, diesen Übelstand zu vermeiden. Sie besteht darin, den Kugeltaschen eine solche Richtung zu geben, daß ihre Achsen oder Mittellinien senkrecht oder hauptsächlich senkrecht zu dem auf die Kugeln wirkenden Lagerdruck stehen, also mit den Drehachsen de'r Kugeln zusammenfallen.The present invention aims to avoid this drawback. she consists in giving the spherical pockets such a direction that their axes or Center lines perpendicular or mainly perpendicular to that acting on the balls Bearing pressure stand, so coincide with the axes of rotation of the balls.
Die Erfindung ist auf der beiliegenden Zeichnung in einigen Ausführungsformen veranschaulicht.The invention is on the accompanying drawing in some embodiments illustrated.
Abb. i ist ein achsialer Schnitt eines Teiles eines doppelreihigen, selbsteinstellenden Kugellagers mit hohlkugeligem Außenlaufring und einem Kugelkäfig gemäß der Erfindung.Fig.i is an axial section of part of a double-row, self-adjusting ball bearing with a spherical outer race and a ball cage according to the invention.
Abb.2 ist ein ähnlicher Schnitt eines doppelreihigen Rillenkugellagers mit schrägen Druckrichtungen, das mit einem etwas abgeänderten Kugelkäfig gemäß der Erfindung versehen ist, und Abb.3 ist eine ähnliche Ansicht eines doppelreihigen Kugellagers mit schräg auswärts gerichteten Lagerdrücken, das ebenfalls mit einem Kugelkäfig gemäß der Erfindung versehen ist.Fig.2 is a similar section of a double row deep groove ball bearing with oblique pressure directions, with a slightly modified ball cage according to of the invention, and Fig.3 is a similar view of a double row Ball bearing with diagonally outward bearing pressures, which is also with a Ball cage is provided according to the invention.
Bei dem in Abb. i gezeigten Lager ist der auf die Kugeln wirkende Lagerdruck längs Radien 0-A und 0-B vom Mittelpunkt der kugeligen Außenlaufbahn durch die Berührungspunkte der Kugeln mit dem Außenring i gerichtet. Die Drehachse u-a einer Kugel steht hauptsächlich senkrecht zu der Richtung 0-A des auf die Kugel wirkenden Druckes. Der Kugelkäfig 3 ist mit seitlich offenen, gebohrten Taschen versehen, deren Achsen oder Mittellinien mit den Drehachsen der zugehörigen Kugeln zusammenfallen. Der Querschnitt des Kugelkäfigs wird zweckmäßig firstförmig, wie in der Zeichnung gezeigt; oder bogenförmig ausgeführt.In the case of the bearing shown in Fig. I, the bearing pressure acting on the balls is directed along radii 0-A and 0-B from the center of the spherical outer raceway through the contact points of the balls with the outer ring i. The axis of rotation of a ball is mainly perpendicular to the direction 0-A of the pressure acting on the ball. The ball cage 3 is provided with laterally open, drilled pockets, the axes or center lines of which coincide with the axes of rotation of the associated balls. The cross-section of the ball cage is expediently ridge-shaped, as shown in the drawing; or curved.
Bei dem in Abb. 2 gezeigten Lager haben die Richtungen O-A ünd 0-B der auf die Kugeln wirkenden Lagerdrücke eine größere Neigung zur Lagerachse als bei dem Lager der Abb. i. Die Neigung der Achsen der Kugeltaschen ist entsprechend ausgeführt, so daß die erwähnten Achsen auch hier senkrecht zu den Druckrichtungen stehen. Irn übrigen ist die Ausführung des Kugelkäfigs 3 im wesentlichen die gleiche wie bei dem Lager nach Abb. i.In the case of the bearing shown in Fig. 2, the directions OA and 0-B of the bearing pressures acting on the balls have a greater inclination to the bearing axis than in the case of the bearing in Fig. I. The inclination of the axes of the spherical pockets is designed accordingly, so that the axes mentioned here are also perpendicular to the printing directions. Otherwise, the design of the ball cage 3 is essentially the same as that of the bearing according to Fig. I.
Abb. 3 zeigt die Erfindung bei einem doppelreihigen Lager bekannter Bauart verwendet, bei dem der Außenring aus zwei Laufbahnringen 4. und 5 mit kugeligen Laufbahnen zusammengesetzt ist, deren Mittelpunkt 0, und 02 auf der Lagerachse in solcher Entfernung voneinander liegen, daß die Kugeldrücke, von der Mittelebene des Lagers aus gerechnet, schräg auswärts gerichtet sind. Der Kugelkäfig ist gemäß der Erfndung entsprechend ausgeführt, so daß die Achsen seiner gebohrten Taschen mit den Drehachsen der Kugeln zusammenfallen.Fig. 3 shows the invention in a double row bearing known Type used in which the outer ring consists of two raceway rings 4. and 5 with spherical Raceways is composed, the center of which is 0, and 02 on the bearing axis in such a distance from each other that the ball pressures, from the median plane of the bearing are directed obliquely outwards. The ball cage is according to executed according to the invention, so that the axes of its drilled pockets coincide with the axes of rotation of the balls.
Die Erfindung kann auch an Kugelkäfigen verwendet werden, die aus Blech gepreßt und mit seitlich offenen Kugeltaschen versehen sind.The invention can also be used on ball cages made from Pressed sheet metal and provided with laterally open ball pockets.
