Description
Kugelrollen, bestehend aus einer Kugel im Widerlager fixiert gelagert, sind bereits bekannt und werden hauptsächlich als Möbelrollen oder sonst zum Verschieben von Gegenständen verwendet. Hierbei ist das Widerlager der Kugel so ausgebildet, daß sich die Kugel unbelastet in jeder Richtung drehen kann, sich aber bei Belastung festsetzt. Es ist bisher nicht gelungen, eine im WiderlagerBall transfer units, consisting of a ball mounted fixed in the abutment, are already known and are mainly used as furniture castors or otherwise for moving objects used. Here, the abutment of the ball is designed so that the ball rotates unloaded in any direction can, but becomes stuck under load. So far it has not been possible to find one in the abutment
ίο fixierte Kugel so zu lagern, daß sie sich nicht bei Belastung festsetzt, selbst dann nicht, wenn die Kugelrolle nur wie vorliegender Erfindungsgegenstand in einer bestimmten Richtung laufen soll.ίο to store the fixed ball so that it does not move sets under load, not even if the ball transfer unit is only like the present subject of the invention should run in a certain direction.
Diesem Übelstand hilft die neue Erfindung dadurch ab, daß hier das Widerlager so gestaltet worden ist, daß die Kugel sich darin selbst bei größter Belastung drehen muß. Dieses wird erreicht durch die neue Ausbildung des Widerlagers der als Rolle dienenden Kugel als schwacher Konus, der die Kugel eben ■ oberhalb ihrer Mittelachse an zwei Punkten berührt, während er in Fahrtrichtung vor und hinter der Kugel frei gearbeitet ist, wodurch die Kugel sich drehen kann. Der Erfindungsgegenstand kann als Rolle für alle Zwecke zum Verschieben von Gegenständen verwendet werden-. In der Zeichnung ist er dargestellt, und zwar zeigt:The new invention remedies this drawback by designing the abutment here has been that the ball must turn in it even with the greatest load. This is achieved through the new training the abutment of the ball serving as a role as a weak cone, which the ball just ■ touches above its central axis at two points while looking in the direction of travel is worked freely in front of and behind the ball, so that the ball can rotate. Of the Subject of the invention can be used as a roller for all purposes for moving items be used-. In the drawing it is shown, namely shows:
Fig. ι eine Seitenansicht, Fig. 2 eine Draufsicht undFig. Ι a side view, Fig. 2 is a plan view and
Fig. 3 die Vorderansicht im Schnitt.3 shows the front view in section.
Die Kugel α liegt in dem Konus b des Widerlagers c und bewegt sich auf der Lauffläche c/. Der Konus ist so gewählt, auch unter Berücksichtigung der Reibungskoeffizienten an der Berührungsstelle der Kugel mit der Lauffläche und dem Konus, daß das Drehmoment aus dem Normaldruck 2 X N mal dem Hebelarm e stets kleiner ist als das Drehmoment aus der Kugelumfangskraft P mal Hebelarm /, so daß die Kugel sich immer drehen muß.The ball α lies in the cone b of the abutment c and moves on the running surface c /. The cone is chosen, also taking into account the coefficient of friction at the point of contact of the ball with the running surface and the cone, that the torque from the normal pressure 2 XN times the lever arm e is always smaller than the torque from the circumferential ball force P times the lever arm /, see above that the ball must always turn.
