Description

Durch vorliegende Erfindung soll bei nachstellbaren Gleitlagern einfachste Nachstellbarkeit, stets zentrisch bleibende Lagerung und axiale Unverschiebbarkeit aller Teile erreicht S werden.The present invention is intended to be extremely easy to adjust for adjustable slide bearings, Always central bearing and axial immovability of all parts achieved S will be.

Der Aufbau und die Wirkungsweise des Erfindungsgegenstandes sind folgende:The structure and mode of operation of the subject matter of the invention are as follows:

Die Welle läuft in mehreren Lagerringen b, c und g, welche sich in einem Lagergehäuse d to befinden.The shaft runs in several bearing rings b, c and g, which are located in a bearing housing d to.

Die Lagerringe b und g (Lagerring b e.vtl. auch in der Mitte des Lagers) haben normales Spiel gegenüber der Welle*? und der lichten Weite des Lagergehäuses und dienen der Zentrierung als Lagerung. Die übrigen Lagerringe c besitzen ein verhältnismäßig großes Spiel, und zwar sowohl der Welle als auch dem Lagergehäuseinneren gegenüber. Sämtliche Ringe besitzen Stifte e, welche in ihnen zugehörige Löcher des jeweiligen Nachbarringes greifen. Der erste Lagerring b ist im Gehäuse d gegen Verdrehen gesichert. Der letzte Lagerring g ist mit Flächen zum Ansetzen eines Schlüssels versehen. Wird dieser letzte Ring g (und damit auch alle anderen Ringe) gedreht, so nähern sich die Scheiben c mit . einer Stelle ihrer Innenbohrung der Welle. The bearing rings b and g (bearing ring b, possibly also in the middle of the bearing) have normal play in relation to the shaft *? and the clear width of the bearing housing and are used for centering as a bearing. The remaining bearing rings c have a relatively large amount of play, both against the shaft and the interior of the bearing housing. All rings have pins e, which engage in them associated holes of the respective neighboring ring. The first bearing ring b is secured against rotation in the housing d. The last bearing ring g is provided with surfaces for attaching a key. If this last ring g (and with it all the other rings) is rotated, the disks c also approach. one point of their inner bore of the shaft.

Die Stifte e und die dazugehörigen Kupplungslöcher/ werden zweckmäßigerweise so angeordnet, daß die Berührung zwischen der Welle und einem Paar benachbart liegender Lagerringe um etwa l8o° versetzt erfolgt. Es wird das Lagerspiel durch eine einfache Drehung am letzten Lagerring g eingestellt. Ist das gewünschte Lagerspiel erreicht, so werden sämtliche Scheiben mit einer Ringmutter h festgezogen und so gegeneinander und im Lagergehäuse festgehalten. Jedes Nachstellen des Lagers besteht nur aus dem Lösen der Mutter h, einer Drehung an der Scheibe g und dem Wiederanziehen der Mutter h. Der zwischen jeder Scheibeninnenbohrung und der Welle entstehende sichelförmige Raum / ergibt eine außerordentliche gute Schmierung des Lagers. Hierdurch ist dieses Lager besonders für schnell lauf ende Wellen, insbesondere für Schleifspindeln, geeignet.The pins e and the associated coupling holes / are expediently arranged in such a way that the contact between the shaft and a pair of adjacent bearing rings is offset by about 180 °. The bearing play is set by simply turning the last bearing ring g . Once the desired bearing clearance has been achieved, all the washers are tightened with a ring nut h and thus held against each other and in the bearing housing. Any readjustment of the bearing consists only of loosening the nut h, turning the washer g and tightening the nut h again. The crescent-shaped space created between each inner disk bore and the shaft results in extremely good lubrication of the bearing. This makes this bearing particularly suitable for high-speed shafts, especially for grinding spindles.

Abgesehen von den niedrigen Herstellungskosten bewährt sich dieses Lager durch den spielfreien Lauf, seine einfache, zuverlässige Nachstellung, Unempfindlichkeit und seine Lebensdauer, besonders bei Schleifspindeln.Apart from the low manufacturing costs, this camp has proven itself through the backlash-free run, its simple, reliable readjustment, insensitivity and its Lifetime, especially with grinding spindles.

Claims (1)

Patentanspruch:Claim: Nachstellbares Gleitlager, insbesondere zur Lagerung von Schleifspindeln, dadurch gekennzeichnet, daß es aus mehreren in einem Lagergehäuse (d) befindlichen geschlossenen ringförmigen Scheiben (b, c und g) besteht, von denen die größere Anzahl (c) ein verhältnismäßig weites Spiel gegenüber der Welle {a) und der lichten Weite des Lagergehäuses aufweist, so daß sie durch Stifte (e) miteinander gekuppelt, etwas exzentrisch gegeneinander verdreht werden können, bis zum gewünschten Spiel gegen die Welle (a). Adjustable slide bearing, in particular for mounting grinding spindles, characterized in that it consists of several closed ring-shaped disks (b, c and g) located in a bearing housing (d) , of which the greater number (c) have a relatively wide clearance with respect to the shaft {a) and the inside width of the bearing housing, so that they can be coupled to one another by pins (e) and rotated somewhat eccentrically against one another, up to the desired play against the shaft (a).
