Abstract

The invention relates to the installation of self-aligning thread bearings in pedestal bearings, flange bearings, ball-and-socket joints or ball-and-socket heads for drives in machines and plant. The prior art is as follows: there are self-aligning ball bearings, self-aligning sliding bearings, ball-and-socket bearings and ball-and-socket heads. On the basis of the invention of the self-aligning thread bearing, the person skilled in the art has the advantage that, in the case of relatively long carriage guides, the socket for the driving screw on the head sides can be bored in an offset position. The self-aligning thread bearing in the saddle or magazine adjusts itself at an angle of 90 degrees to the thread 1. By means of the flange nut 2 and inner ring 4 with the spherical shape 7 in the housing 0, the pendulum motion of the thread 1 relative to the swivelling motion alpha ( alpha ) in relation to the centre of rotation 13 and the swivelling motion beta ( beta ) compensates for the angular inaccuracy. In the case of carriage guides provided by round shafts and recirculating ball sleeves, it is possible to dispense with the second round shaft since the self-aligning thread bearing can assume the guiding function by means of the thread 1. <IMAGE>

Description

Die Erfindung betrifft den Einbau einer Flanschgewindemutter in Stehlager, Flanschlager, Gelenklager oder Gelenkköpfe.The invention relates to the installation of a flange nut in pillow blocks, flange bearings, spherical bearings or Rod ends.

Der Stand der Technik ist folgender, das es Selbsteinstellende und Selbstausrichtende Pendelkugellager, Pendelgleitlager, Gelenklager und Gelenkköpfe gibt.
Selbstausrichtende Pendelgewinde in Lagergehäuse gibt es nicht.The prior art is as follows, that there are self-aligning and self-aligning self-aligning ball bearings, self-aligning plain bearings, spherical plain bearings and rod ends.
There are no self-aligning pendulum threads in the bearing housing.

Lagergehäuse mit Pendelkugellager erhalten im allgemeinen einen Kugelsitz, so daß sie selbsteinstellend werden. Wenn der Kugelsitz jedoch leichtgängig ist, besteht die Gefahr, das der Innenring ins Taumeln gerät, wenn das Lager wenig belastet wird.Bearing housings with self-aligning ball bearings are generally preserved a ball seat so that they become self-adjusting. However, if the ball seat is smooth, there is Danger of the inner ring staggering when the bearing is little burdened.

Bei herkömmlichen Lagern ist im Außenring des Lagers ein Schmiermitteldurchlaß gebohrt, der eine Gewindebohrung hat, zur Aufnahme eines Schmiernippels. In der Schmiermittelbohrung wird ein runder Stab bis zur Einsenkung im kugelförmigen Innenring eingelassen.In conventional bearings, there is a in the outer ring of the bearing Bored lubricant passage that has a threaded hole to accommodate a grease nipple. In the lubricant hole becomes a round rod up to the depression in the spherical Inner ring embedded.

Eine weitere Variante zur verhinderung der Taumel bzw. der Begrenzung des kugelförmigen Innenringes ist, das eine Kugel zwischen Innen und Außenring über das Schmierloch eingebaut wird.Another variant to prevent the wobble or the Limitation of the spherical inner ring is that a ball installed between the inner and outer ring via the lubrication hole becomes.

Die Merkmale und Vorteile der Erfindung von Pendelgewindelager werden in der nachstehenden und zeichnerische Darstellung Fig. 1 Seite 5, in einem Ausführungsbeispiel beschrieben.The features and advantages of the invention of self-aligning thread bearings are described in an exemplary embodiment in the illustration below and in the drawing in FIG. 1 page 5.

Auf Grund der Erfindung des Pendelgewindelagers werden sich für den Fachmann zahlreiche Varianten ergeben, die bei der Konstruktion zum Beispiel bei langen Schlittenführungen (Schwalbenschwanzführungen oder Rundwellen mit Kugelführungsbüchsen) Antriebsprobleme durch Winkelungenauigkeiten nicht mehr entstehen. Magazine und Supporte die Heute durch Schweißkonstruktionen erstellt werden, können ohne Bearbeitung der Aufspannflächen für den Antrieb mittels Flansch oder Stehlager mit dem Pendelgewindelager montiert werden. Due to the invention of the self-aligning thread bearing result in numerous variants for the person skilled in the art Construction for example for long slide guides (Dovetail guides or round shafts with ball guide bushes) Drive problems caused by angular inaccuracies arise more. Magazines and supports today with welded constructions can be created without editing the Clamping surfaces for the drive using a flange or pillow block be mounted with the self-aligning thread bearing.  

Pendellageraufbau bestehend aus einem Gehäuse Pos. 0 mit kugelligem Außenring, der mit einem kugelförmigen Innenring Pos. 4 über ein Schlitz Pos. 11 im Gehäuse Pos. 0 eingesetzt wird. Durch Einsetzen einer Flanschgewindemutter Pos. 2 in den kugelförmigen Innenring Pos. 4, wird die Flanschgewindemutter mittels Befestigungsschrauben Pos. 12 angeschraubt. Die Pendelbewegung der Achse Pos. 1, zur Schwenkbewegung X zu X 1 und Winkel Alpha zum Drehpunkt Pos. 13, wird durch den runden Stab Pos. 8 sowie Ansenkung Pos. 6 im Innenring Pos. 4 begrenzt. Das gleiche gilt für die Winkelverstellung der Y Achse Pos. 1 mit dem Winkel Beta bei der Verstellung. Mit der Schmiermittelbohrung Pos. 9 und Radiuseinfräsung wird im runden Stab Pos. 8 die Schmiermittelzuführung gewährleistet. Ein Zwischenraum zwischen Schmiernippel Pos. 10 und runder Stab. Pos. 8 verhindert ein Einklemmen des kugelförmigen Innenringes Pos. 4 beim verdrehen zum Aussenring Pos. 0. Die Einfräsung Pos. 9 auf den Kopfseiten des runden Stabes Pos. 8 garantiert auch bei falschen Einbau ein Schmiermitteldurchlaß.Self-aligning bearing assembly consisting of a housing item 0 with a spherical outer ring, which is used with a spherical inner ring item 4 via a slot item 11 in the housing item 0 . By inserting a flange nut item 2 into the spherical inner ring item 4 , the flange nut is screwed on using fastening screws item 12 . The pendulum movement of the axis pos. 1 , for the swivel movement X to X 1 and the angle alpha to the pivot point pos. 13 , is limited by the round rod pos. 8 and countersink pos. 6 in the inner ring pos. 4 . The same applies to the angular adjustment of the Y axis pos. 1 with the beta angle during the adjustment. The lubricant supply is ensured in the round rod pos. 8 with the lubricant hole pos. 9 and radius milling. A space between the grease nipple pos. 10 and the round rod. Item 8 prevents the spherical inner ring item 4 from becoming jammed when rotating to the outer ring item 0 . The milled-in item 9 on the top of the round rod item 8 guarantees a lubricant passage even if installed incorrectly.

Die Schmiermittelbohrung Pos. 3 in der Flanschgewindemutter Pos. 2 muß mindestens den Durchmesser haben, wie der Verstellweg Flanschgewindemutter. The lubricant hole pos. 3 in the flange nut pos. 2 must have at least the same diameter as the adjustment path of the flange nut.
