Abstract

The bearing supports (2), concentric to the centre point, are equally distributed over the base plate to which they are screwed. By rotation of a threaded bush (1), the cone roller (8) is located and arrested against an output flange. The forces produced are absorbed via the cone roller (8) and shaft (3) via bearings (4-6) and a plate spring (7). The load peaks occurring during milling operations are picked up elastically by the plate spring (7), and distributed equally to all bearing supports. The shaft (3) has the convexly ground cone roller (8) fitted on it, and is axially displaceably located at an outward angle (alpha) in a bearing support (2). It is supported by a plate spring (7). USE - As an output flange bearing arrangement in a spring roller milling gear.

Description

Abtriebsflanschlagerung bei einem Federrollenmühlenge­ triebe.Output flange mounting for a spring roller mill drives.

Die Leistungsfähigkeit und Betriebssicherheit einer Federrollenmühle hängt im wesentlichen von der funktionellen Gestaltung der die Mehlschüssel aufnehmenden Abtriebsflanschlagerung ab.The performance and operational reliability of a Spring roller mill depends essentially on that functional design of the flour bowl Output flange mounting.

Diese Baugruppe unterliegt beim rauhen Betrieb des Mahlvorgangs besonderen Stoßbelastungen und stellt daher besonders hohe Anforderungen an die Lagerung zur Aufnahme der variierenden Vertikallast.This assembly is subject to the rough operation of the Grinding process special shock loads and therefore represents particularly high storage requirements for admission the varying vertical load.

Die bisher überwiegend in der Praxis eingesetzte Ölflutgleitlagerung wurde zwecks Aufwandsverringerung bei kleinen und leistungsschwächeren Typen bereits durch die Anwendung eines einzigen geschlossenen Pendelrollenlagers abgelöst. Dieser Lösung des Lagerproblems sind jedoch material- und aufwandseitig Grenzen gesetzt. (Fachzeitschrift "Zement-Kalk-Gips" Nr. 11/B1). Daher ist bereits vorgeschlagen worden, die Abtriebsflanschlagerung mit speziellen Lagerböcken, welche auf einer Grundplatte und in zum Mittelpunkt führenden Paßnuten befestigt sind, zu bewerkstelligen, wobei die Lagerböcke in ihrem Aufbau mit drehbar gelagerter Welle und über ein Schwenklager abgestützter Kegelrolle vollständig identisch sind (DD 258 324).The oil flood plain bearing used mainly in practice has already been replaced by the use of a single closed spherical roller bearing in order to reduce the effort required for small and less powerful types. However, there are limits to this solution to the storage problem in terms of material and effort. (Trade journal "Zement-Kalk-Gips" No. 11 / B 1 ). It has therefore already been proposed to accomplish the output flange mounting with special bearing blocks which are fastened on a base plate and in fitting grooves leading to the center, the bearing blocks being completely identical in their construction with a rotatably mounted shaft and a tapered roller supported by a pivot bearing (DD 258 324).

Diese Art der Abtriebsflanschlagerung hat nach Meinung der Fachwelt Vorteile in bezug auf die Verringerung der Anlagenmasse, Justierung, Überwachung und Wartung, jedoch wird diese Lösung insgesamt als zu statisch angesehen, um die auftretenden Stoßbelastungen ohne negativen Einfluß auf die Lebensdauer zu kompensieren.In the opinion of the Professional benefits in terms of reducing the Plant mass, adjustment, monitoring and maintenance, however overall this solution is considered too static to the occurring shock loads without negative influence to compensate for the lifespan.

Der im Anspruch angegebenen Erfindung liegt daher das zu lösende Problem zugrunde, eine Antriebsflanschlagerung zu schaffen, die zum Abfangen von Belastungsspitzen sowie zum Ausgleich von Tragunterschieden zwischen den einzelnen Lagerböcken nicht nur geeignet ist, sondern die mit den erfindungsgemäßen Mitteln verbundenen Vorteile, wie gleichmäßige Lastverteilung, Entlastung des Getriebegehäuses, Verhinderung des Kantentragens der Kegelrollen, Erhöhung der Zuverlässigkeit der gesamten Axiallagerung, Verringerung des Wartungs- und Reparaturaufwandes, vollständig zur Wirkung bringt.The invention specified in the claim is therefore due solving problem based on a drive flange mounting create that for the interception of peak loads as well as Compensation of differences in load between the individual Bearing blocks is not only suitable, but the one with the  Advantages associated with agents, such as even load distribution, relief of the Gear housing, prevention of edge wear Tapered rollers, increasing the reliability of the whole Axial bearing, maintenance and reduction Repair effort, fully effective.

Die Erfindung wird nunmehr anhand eines in der Zeichnung dargestellten Ausführungsbeispieles beschrieben.The invention is now based on one in the drawing illustrated embodiment described.

Die Figur zeigt einen Schnitt durch den Lagerbock.The figure shows a section through the bearing block.

Die Lagerböcke 2 werden, gleichmäßig auf dem Umfang verteilt, konzentrisch zum Mittelpunkt auf der nicht dargestellten Grundplatte aufgeschraubt. Durch Verdrehen der Gewindebuchse 1 wird die Kegelrolle 8 jeweils gegen den nicht dargestellten Abtriebsflansch angestellt und arretiert. Die auftretenden Kräfte werden über die Kegelrolle 8 und Welle 3 durch die Lager 4, 5 und 6 sowie die Tellerfeder 7 aufgenommen. Die im Mahlbetrieb auftretenden Belastungsspitzen werden von der Tellerfeder 7 elastisch abgefangen und gleichmäßig auf alle Lagerböcke verteilt. Ein Kantentragen der Kegelrolle 8 wird durch den Balligschliff verhindert, wobei die Geometrie der Kegelrolle 8 in Verbindung mit dem Winkel α einen schlupffreiem Lauf garantiert.The bearing blocks 2 are, evenly distributed over the circumference, screwed concentrically to the center on the base plate, not shown. By turning the threaded bushing 1 , the tapered roller 8 is set and locked against the output flange (not shown). The forces occurring are absorbed by the tapered roller 8 and shaft 3 through the bearings 4, 5 and 6 and the plate spring 7 . The load peaks occurring in grinding operation are intercepted elastically by the plate spring 7 and evenly distributed over all bearing blocks. Edge wear of the tapered roller 8 is prevented by the spherical grinding, the geometry of the tapered roller 8 in conjunction with the angle α guaranteeing a slip-free run.
