Description

Schleifspindellagerung mit mindestens einem Schulterkugellager Die Erfindung bezieht sich auf eine Schleifspindellagerung mit mindestens einem Schulterkugellager, das einerseits zwei durch mehrere konzentrisch zur Spindelachse angeordnete Druckfedern axial verspannte Außenringe mit einem gemeinsamen. sowie an einer Schulter der Spindel anliegenden Innenring aufweist und das andererseits in einer glatten Bohrung des Spindelgehäuses durch einen in einer Ringnut sitzenden sowie mit einem der Außenringe zusammenwirkenden Sprengring axial festgehalten ist.Grinding spindle bearing with at least one shoulder ball bearing Die The invention relates to a grinding spindle bearing with at least one shoulder ball bearing, On the one hand, two compression springs arranged concentrically to the spindle axis axially tensioned outer rings with a common. as well as on one shoulder of the spindle has adjacent inner ring and the other hand in a smooth bore of the Spindle housing by a seated in an annular groove and with one of the outer rings cooperating snap ring is held axially.

Bei den bekannten Schleifspindellagerungen dieser Art sind für die axiale Festlegung der Außenringe im Gehäuse Bunde vorgesehen, durch die der Durchmesser der Spindel begrenzt wird. Es ist aber auch bereits die axiale Festhaltung von Wälzlagern in glatten Gehäusebohrungen durch in einer Ringnut gehaltene Sprengringe bekannt. Bei dieser Spindellagerung ist die Ringnut im Gehäuse angeordnet. Sie ist daher nicht einfach und genau herzustellen, wodurch die unbedingte Spielfreiheit der angestellten Lager nicht gewährleistet ist, was sich wiederum in einem unsauberen Schliff und einem zu häufigen Auswechseln der Lager nachteilig auswirkt.In the known grinding spindle bearings of this type are for axial fixing of the outer rings in the housing provided collars through which the diameter the spindle is limited. But it is also the axial retention of rolling bearings known in smooth housing bores by retaining rings in an annular groove. With this spindle mounting, the annular groove is arranged in the housing. She is therefore not easy and precise to manufacture, which means that the employees are completely free of play Bearing is not guaranteed, which in turn results in an unclean finish and too frequent replacement of the bearings is detrimental.

Die geschilderten Nachteile sind durch die Erfindung bei einer Schleifspindellagerung der eingangs erwähnten Art dadurch behoben, daß erfindungsgemäß der auf der Gehäuseaußenseite sitzende Außenring etwa in der Ebene der Nabenstirnseite der Gehäusebohrung zur Aufnahme des Sprengringes ringförmig genutet ist und durch vorgespannte Tellerfedern in Richtung Gehäusemitte und damit der Sprengring an die Nabenstirnseite gepreßt wird. Durch die erfindungsgemäße Anordnung ist der Vorteil vermittelt, daß sich die im Außenring befindliche Ringnut einfacher und genauer herstellen läßt als die bisher im Innern der Gehäusebohrung angeordnete Ringnut. Darüber hinaus ergibt sich der Vorteil, daß das Auswechseln schadhafter Lager nur einen Bruchteil der bisher dafür benötigten Zeit erfordert.The disadvantages outlined are due to the invention in a grinding spindle bearing remedied of the type mentioned in that, according to the invention, on the outside of the housing seated outer ring approximately in the plane of the hub face of the housing bore Recording of the snap ring is grooved in a ring shape and by pretensioned disc springs towards the center of the housing and thus the snap ring pressed against the hub face will. The arrangement according to the invention has the advantage that the ring groove located in the outer ring can be produced more easily and more precisely than that Annular groove previously arranged inside the housing bore. In addition, it arises the advantage that the replacement of defective bearings is only a fraction of what was previously required time required for this.

Die Erfindung ist in der nachstehenden Beschreibung an Hand der Zeichnung erläutert, in welcher der schleifscheibenseitige Teil einer Schleifspindel mit Lagerung und Gehäuse im Axialschnitt dargestellt ist.The invention is illustrated in the following description with reference to the drawing explains in which the grinding wheel-side part of a grinding spindle with bearing and housing is shown in axial section.

Die die Schleifscheibe 1 tragende Spindel 2 ist mindestens auf der der Schleifscheibe zugekehrten Seite in einer Wälzlageranordnung gelagert, die aus einem gemeinsamen Innenring 3, den Kugeln 4 sowie zwei Schultern aufweisenden Außenringen 5, 6 besteht, die durch in Aufnahmen 7 sitzende Druckfedern 8 auseinandergedrückt werden. Der in Axialrichtung äußere Lageraußenring 5 trägt in einer Nut den Sprengring 9, durch den allein die axiale Festlegung der Wälzlageranordnung an der Nabenstirnseite 10 des Gehäuses 11 vermittelt wird. Der Lageraußenring 5 steht unter dem Druck der gegen den Lagerdeckel 12 abgestützten Tellerfedern 13, die ihn mit seinem Sprengring 9 gegen die Nabenstirnseite 10 andrücken.The spindle 2 carrying the grinding wheel 1 is mounted at least on the side facing the grinding wheel in a roller bearing arrangement, which consists of a common inner ring 3, the balls 4 and two outer rings 5, 6 with two shoulders, which are pressed apart by compression springs 8 seated in receptacles 7 . The outer bearing ring 5 in the axial direction carries the snap ring 9 in a groove, through which only the axial fixing of the roller bearing arrangement on the hub face 10 of the housing 11 is conveyed. The bearing outer ring 5 is under the pressure of the plate springs 13 which are supported against the bearing cover 12 and which press it with its snap ring 9 against the hub face 10 .

Die nachstehend genannten Maßnahmen bilden keinen Teil der Erfindung: In dem Gehäuse 11 und dem Lagerdeckel 12 befindet sich eine Ansaugbohrung 14, durch welche bei Umdrehung des durch die Verschraubung 15 mit der Welle 2 verbundenen Gehäusedeckels 16 Luft angesaugt wird. Die Ansaugwirkung wird durch ein Schleudergewinde 17 noch verstärkt. An dem Lagerdeckel 12 ist ein radial nach außen gerichteter Flansch 18 vorgesehen, welcher die angesaugte Luft umlenkt und dazu beiträgt, daß sie bei ihrem Austritt bei 19 einen Windschirm bildet, welcher den Eintritt von Schleifwasser in die schleifscheibenseitige Lagerung zuverlässig verhindert.The measures mentioned below do not form part of the invention: In the housing 11 and the bearing cover 12 there is a suction hole 14 through which air is sucked in when the housing cover 16 connected to the shaft 2 by the screw connection 15 rotates. The suction effect is reinforced by a centrifugal thread 17. On the bearing cover 12 a radially outwardly directed flange 18 is provided, which deflects the sucked air and helps that it forms a windshield when it exits at 19, which reliably prevents the entry of grinding water into the grinding wheel-side bearing.
