Description

Mühlsteinbefestigung für den oberen Mühlstein bei Mühlen mit sich drehendem Bodenstein und durch Schraubenspindel verstellbarem, gegen Drehung gesichertem Oberstein Die Erfindung betrifft eine Mühlsteinbefestigung für den oberen Mühlstein bei Mühlen mit sich drehendem Bodenstein und durch Schraubspindel verstellbarem, gegen Drehung gesichertem Oberstein.Millstone attachment for the upper millstone at mills with itself rotating floor stone and adjustable by screw spindle, secured against rotation Oberstein The invention relates to a millstone attachment for the upper millstone in mills with a rotating base stone and adjustable by means of a screw spindle, Oberstein secured against rotation.

Das Neue bei der Erfindung besteht darin, daß das untere- Ende der Schraubenspindel zu einem Bügel ausgebildet ist, in dem der U-förmig gebogene Bügel des Obersteines allseitig beweglich aufgehängt ist.The novelty of the invention is that the lower end of the Screw spindle is formed into a bracket, in which the U-shaped bent bracket of the upper stone is suspended on all sides so that it can move.

Durch. die Vorrichtung werden die Nachteile bei Einrichtungen ähnlicher Art, wie eine stetige Verschiebung der Spindel in axialer Richtung, Verschiebung des Halslagers im Bodenstein, die oft eintretende Verschiebung des Balancierlagers im Oberstein, die kurze Lebensdauer des Halslagers infolge Eindringens von Verunreinigungen und scharfen Teilchen sowie die kurze Lebensdauer infolge starker Abnutzung des Halslagers, vermieden.By. the device becomes more similar to the disadvantages in devices Kind of like a steady displacement of the spindle in the axial direction, displacement of the neck bearing in the Bodenstein, the shifting of the balancing bearing that often occurs in Oberstein, the short service life of the neck bearing due to the ingress of impurities and sharp particles as well as the short service life due to heavy wear of the Neck bearing, avoided.

Auf der beiliegenden Zeichnung ist eine Ausführungsform des Erfindunggegenstandes veranschaulicht, und zwar zeigt Abb. i einen senkrechten Schnitt durch die Mühlsteinbefestigung, Abb. 2 eine Draufsicht auf die die Drehung hindernde Sicherungsvorrichtung, Abb.3 eine Seitenansicht des Bügels mit seiner Befestigung ain Stein.On the accompanying drawing is an embodiment of the subject matter of the invention illustrated, namely Fig. i shows a vertical section through the millstone attachment, Fig. 2 is a plan view of the anti-rotation locking device, Fig. 3 a side view of the bracket with its attachment ain stone.

Der Oberstein i ismit einem Bügel :2 versehen, welcher mittels eingegossenen Bolzen 3 am Stein befestigt ist. Der Bügel 2 wird von einem anderen Bügel q. gehalten, in welchem der Oberstein hängt, und zwar unter Vermittlung einer Kugel, so daß die Lagerung eine äußerst leichte und fast reibungsfreie ist. Der Bügel q. dagegen ist an einer Schraubenspindel 5 befestigt, deren Gewinde von Gewindegängen in der Bohrung eines auf einem Rahmen gelagerten, auf einem Kugellager ruhenden Kegelrades 6 aufgenommen wird, welches mit einem Kegelrad 7 in Eingriff steht. Diese Lagerung des Obersteins ist eines der wichtigsten Merkmale der Vorrichtung nach der vorliegenden Erfindung.The upper stone is provided with a bracket : 2, which is attached to the stone by means of cast bolts 3. The bracket 2 is from another bracket q. held, in which the Oberstein hangs, with the mediation of a ball, so that the storage is extremely easy and almost frictionless. The bracket q. on the other hand, it is attached to a screw spindle 5, the thread of which is received by threads in the bore of a bevel gear 6 which is mounted on a frame and resting on a ball bearing and which is in engagement with a bevel gear 7. This bearing of the top stone is one of the most important features of the device according to the present invention.

Zwecks Führung des Obersteins ist dieser mit einer besonderen Vorrichtung ausgestattet. In Führungen 8 sind Führungszapfen g verschiebbar angeordnet, so daß eine parallele Verschiebung des Steines ermöglicht wird. Die Zapfen 9 haben dabei eine solche Form erhalten, daß sie eine Schwenkung des Steines sowohl in der waagerechten als auch in der senkrechten Ebene gestattet. Der Bodenstein io ruht auf einer Welle ii, welche von zwei Lagern 12 und 13 geführt wird, sowie einem axialen Traglager 1d..In order to guide the upper stone, it is equipped with a special device fitted. In guides 8 guide pins g are slidably arranged so that a parallel displacement of the stone is made possible. The pin 9 have it Get such a shape that it swivels the stone both in the horizontal as well as in the vertical plane. The Bodenstein io rests on a shaft ii, which is guided by two bearings 12 and 13, and an axial support bearing 1d ..
