Description
Die Erfindung betrifft Preß.stoffkörper mit tolerierter Bohrung zum Aufsetzen auf Tragkörper, insbesondere Schleifringkörper, Wicklungs.trüger od. dgl. für elektrische Maschinen..The invention relates to Preß.stoffkörper with tolerated bore for Put on support body, in particular slip ring body, Wicklungs.trüger or the like. for electrical machines ..
Um bei Preßteilen eine tolerierte Bohrung (Preßsitz und Festsitz) zu erzielen, ist eine mechanische Bearbeitung notwendig. Der bei der Bearbeitung auftretende hohe Werkzeugverschleiß, bedingt ständige Änderung der Werkzeugeinstellung, und es entsteht da-durch ,außer einer Verteuerung des. Arbeitsganges oftmals Aus.schuß. Es wurde deshallb angestrebt, Bohrungen mittels Pressen zu erreichen, bei denen eine mechanische Bearbeitung nicht erforderlich ist. Die in dieser Richtung durchgeführten Versuche dübrten jedoch nicht zum gewünschten Ziel, da die Preßstoffkörper, insbesondere unter der Einwirkung von Wärmedehnungen, leicht Risse bekamen oder zerplatzten..In order to achieve a tolerated bore (press fit and interference fit) in pressed parts Mechanical processing is necessary to achieve this. The one in the process of editing Occurring high tool wear, requires constant change of the tool setting, and as a result, apart from making the operation more expensive, there is often waste. The aim was therefore to achieve bores by means of presses, in which mechanical processing is not required. Those carried out in this direction Attempts, however, do not achieve the desired goal, since the molded bodies, in particular under the action of thermal expansion, easily cracked or burst ..
Gemäß der Erfindung werden nun Preßstoffkörper mit tolerierter Bohrung, bei welchen die vorerwähnten Nachteile nicht auftreten, dadurch erreicht, daß man auf der Innenseite der Bohrungswand Rippen geringer Höhe vorsieht. Diese Rippen sind möglichst flach gehalten und haben eine Höhe, die im allgemeinen nur einen Bruchteil eines Millimeters darstellen wird. In der Zeichnung. ist ein Ausführungsbeispiel angegeben..According to the invention are now molded bodies with tolerated bore, in which the aforementioned disadvantages do not occur, achieved by provides ribs of small height on the inside of the bore wall. These ribs are kept as flat as possible and have a height that is generally only one Will represent a fraction of a millimeter. In the drawing. is an embodiment specified ..
Fig. i zeigt einen Schleifringkörper in. Seitenansicht und Längsschnitt und Fig. 2 eine .Stirnansicht zu Fig. i.Fig. I shows a slip ring body in. Side view and longitudinal section and FIG. 2 is a front view of FIG.
Der Schleifringkörper i, dessen ,Schleifringe mit 2 .bezeichnet sind, hat eine Bohrung 3,, deren Innenwand mit flachen sehr niedrigen Rippeni q. versehen ist. Diese Rippen gewährleisten ohne besondere Bearbeitung der Bohrung 3 einen sicheren Paßsitz, die eingangs erwähnten Nachteile der bisherigen Anordnungen kommen in Fortfall, und ein Platzen oder Reißen des Preßkörpers infolge Wärmedehnung kommt nicht mehr vor.The slip ring assembly i, the slip rings of which are marked with 2. has a bore 3 ,, whose inner wall with flat, very low ribs i q. Mistake is. These ribs ensure that the bore 3 is safe without any special machining Fit, the disadvantages of the previous arrangements mentioned at the beginning are no longer applicable, and bursting or tearing of the compact due to thermal expansion no longer occurs before.
