Abstract
Wälzlager von einem Gehäuse (1) und einer Welle (2) mit dazwischenliegendem Wälzkörpersatz (5) dadurch gekennzeichnet, dass die Wälzkörper (5) nicht alle den gleichen, identischen Abrolldurchmesser besitzen und einzelne Wälzkörper (6) eine Durchmesser-Vergrößerung haben, so dass ein zu erzeugendes Bremsmoment in Relation zu den Passungsverhältnissen von Gehäuse (3)- und Wellendurchmesser (4) entsteht.Rolling bearing of a housing (1) and a shaft (2) with an intermediate rolling element set (5), characterized in that the rolling elements (5) do not all have the same, identical rolling diameter and individual rolling elements (6) have a diameter increase, so that A braking torque to be generated is created in relation to the fit ratios of the housing (3) and shaft diameter (4).
Description
Die Erfindung betrifft Wälzlager mit einem Wälzlagersatz, der ein zusätzliches Bremsmoment integriert.The invention relates to rolling bearings with a rolling bearing set, which integrates an additional braking torque.
Wälzlager der hier angesprochenen Art sind bekannt; unter
Desweiteren stellt
In
Aufgabe der Erfindung ist es daher, ein Wälzlager über den Wälzkörpersatz mit integriertem Bremsmoment zu entwickeln.The object of the invention is therefore to develop a rolling bearing on the rolling element with integrated braking torque.
Die Aufgabe wird dadurch gelöst, daß das Wälzlager entgegen üblicher Anordnung mit ein oder mehreren im Durchmesser vergrößerten Wälzkörpern versehen ist, die auf Basis der Laufbahnpaarung von Gehäuse- und Wellendurchmesser gemäß dem erforderlichen, zu integrierenden Zusatzreibmoment bestimmt sind.The object is achieved in that the rolling bearing is provided, contrary to the usual arrangement with one or more enlarged diameter rolling elements, which are determined on the basis of the pair of raceway housing and shaft diameter according to the required, to be integrated Zusatzreibmoment.
Darüber hinaus ist diese reibungsangepasste Wälzlagerung auch in Verbindung mit Wälzlagerringen und als vollständiges Bremslager mit abgestimmtem Reibmoment einsetzbar.In addition, this friction-adapted rolling bearing can also be used in conjunction with roller bearing rings and as a complete brake bearing with a matched friction torque.
Die Wahl der Wälzkörper ist jeweils von der Art der Anwendung, dem Bauraum und der Belastung abhängig.The choice of rolling elements depends on the type of application, the installation space and the load.
Die Abhängigkeit des zu induzierenden Reibmomentes in Bezug auf Anzahl bzw. Vergrößerung des Wälzkörperdurchmessers ist über empirische Reibmoment-Meßreihen festgelegt. Die im Durchmesser vergrößerten Wälzkörper können vorzugsweise durch verschleißärmere Wälzkörperwerkstoffe, wie z. B. Keramikmaterialien eingesetzt werden.The dependence of the friction torque to be induced in relation to the number or increase in the rolling body diameter is determined by empirical friction torque measurement series. The enlarged in diameter rolling elements can preferably by low-wear rolling elements, such. B. ceramic materials are used.
Die Erfindung wird an einem Ausführungsbeispiel näher erläutert:The invention will be explained in more detail with reference to an exemplary embodiment:

In
In
Die Erfindung erstreckt sich in gleicher Ausführung auf alle Arten von Wälzlagern mit jeglicher Form von Wälzkörpern.The invention extends in the same design to all types of bearings with any form of rolling elements.
Die beschriebene Erfindung von derartigen Wälzlagern mit integrierter Bremswirkung ist sehr wirtschaftlich, da der einzubauende Wälzkörpersatz sich rein über die Passungssituation von Gehäuse und Welle oder über die Laufbahndurchmesser-Paarung bestimmen lässt. Auch sind keinerlei bauraumveränderte Zusatzelemente zur Erzielung der Bremswirkung nötig, die aufwendig und teuer sind. Alle herkömmlichen Lager-Funktionen wie Aufnahme radialer und axialer Kräfte bleiben erhalten.The described invention of such rolling bearings with integrated braking effect is very economical, since the Wälzkörpersatz to be installed can be determined purely on the fit situation of housing and shaft or on the raceway diameter pairing. Also, no installation space modified additional elements to achieve the braking effect necessary, which are complicated and expensive. All conventional bearing functions such as radial and axial forces are retained.
