Description
Es ist bereits vorgeschlagen worden, bei der Lagerung von Spindeln, welche einer einseitigen Beanspruchung ausgesetzt sind, außer den üblichen die Spindel umgebenden Lagerschalen besondere, lediglich die einseitige Beanspruchung aufnehmende Lager anzuordnen, und zwar dienen hierzu Kugel- oder Rollenlager, deren innerer Ring festliegt, während der äußere Ring sich gegen die Spindel stützt und auf ihr abrollt.It has already been proposed in the storage of spindles, which one-sided Are exposed to stress, except for the usual bearing shells surrounding the spindle to arrange special bearings that only absorb the one-sided load, namely ball or roller bearings, whose inner ring is fixed, while the outer ring is supported against the spindle and rolls on it.
Die vorliegende Erfindung bezweckt eine Ausgestaltung dieser Einrichtung so, daß sie auch für die Lagerung der Arbeitsspindeln von Werkzeugmaschinen verwendbar wird, bei denen auf eine möglichst gedrängte Anordnung zum Zwecke der Raumersparnis Rücksicht zu nehmen ist, um eine Beeinträchtigung der Güte der Arbeit infolge einer durch den Riemenzug entstandenen einseitigen Ab-.nutzung der Lagerschalen vorzubeugen.The present invention aims to design this device so that it can also be used for the storage of the work spindles of machine tools which consider an arrangement that is as compact as possible in order to save space is to be taken to avoid any deterioration in the quality of the work as a result of the To prevent unilateral wear of the bearing shells caused by belt tension.
Zu diesem Zweck sind die den Riemenzug aufnehmenden Lager in Schlitzen des Lagers selbst angeordnet. Um eine Einstellbarkeit zu erzielen, können die Befestigungsbalzen der Lager, die vorzugsweise Kugellager sind, exzentrisch ausgebildet sein.For this purpose, the belt pull receiving bearings are in slots of the bearing arranged itself. In order to achieve adjustability, the fastening bolts of the bearings, which are preferably ball bearings, be eccentric.
Die Zeichnung zeigt eine beispielsweise Ausführungsform der Erfindung, und zwar istThe drawing shows an example embodiment of the invention, namely is
Abb. ι ein Schnitt durch den in Betracht kommenden Teil eines solchen Lagers, undFig. Ι a section through the relevant part of such a camp, and
Abb. 2 ist ein Schnitt in der Richtung A-B von Abb. 1.Fig. 2 is a section in the direction AB of Fig. 1.
Das in der Zeichnung dargestellte LagerThe bearing shown in the drawing
besteht aus dem Lagerbock α und dem Lagerdeckel b, welche durch die Schrauben c zusammengehalten werden. In den Teilen a und b sind die Lagerschalen h in an sich bekannter Weise angeordnet. Die Schalen können nach Belieben und den jeweiligen Verhältnissen entsprechend aus einem Stück bestehen, sie können aber auch zwei- oder mehrteilig ausgebildet und nachstellbar eingerichtet sein; schließlich können sie aus einem beliebigen Material bestehen oder mit einem Lagermetall ausgefüttert sein ti. dgl. mehr.consists of the bearing block α and the bearing cover b, which are held together by the screws c . In parts a and b , the bearing shells h are arranged in a manner known per se. The shells can consist of one piece at will and according to the respective conditions, but they can also be designed in two or more parts and set up adjustable; after all, they can be made of any material or lined with a bearing metal ti. like. more.
Gemäß der Erfindung sind nun in Aussparungen d des Deckels besondere Kugellager vorgesehen. Der innere Ring der Kugellager sitzt auf Bdzen e, welche in den Lagerdeckel eingesetzt und in beliebiger Weise in ihm gesichert sind, während der äußere Ring/ der Kugellager, der außen sauber abgeschliffen ist, durch eine Aussparung der Lagerschale h hindurchragt und unmittelbar auf der Spindel g aufliegt.According to the invention, special ball bearings are now provided in recesses d of the cover. The inner ring of the ball bearings sits on Bdzen e, which are inserted into the bearing cover and secured in it in any way, while the outer ring / ball bearing, which is cleanly ground on the outside, protrudes through a recess in the bearing shell h and directly on the spindle g rests.
Bei dem Ausführungsbeispiel sind zwei derartige Kugellager dargestellt. Ihre Anzahl ist aber natürlich eine beliebige. Man ordnet die Lager so an, daß der gesamte Zug des Riemens durch sie aufgenommen wird. Zweckmäßig wird man sie nachstellbar machen, ζ. Β. dadurch, daß man den in den mittleren Ring des Kugellagers eingreifenden Teil der BoI-zen e gegenüber dem übrigen Teil exzentrisch macht, so daß durch Drehen des Bolzens das ganze Kugellager der Spindel genähert oder von ihr entfernt werden kann. Die Kugellager können natürlich auch durch Rollenlager, Gleitlager o. dgl. ersetzt werden.In the embodiment, two such ball bearings are shown. However, their number is of course any number. The bearings are arranged so that all of the tension on the belt is taken up by them. Appropriately, they will be made adjustable, ζ. Β. characterized in that one makes the engaging in the central ring of the bearing part of the boi-zen e relative to the remaining part eccentrically so that approached the whole ball bearing of the spindle by rotating the bolt or can be removed from it. The ball bearings can of course also be replaced by roller bearings, plain bearings or the like.
