Description
Kaffeemühle Die Erfindung betrifft eine Kaffeemühle, dr-ren Mahlkegel auf einem in ihm liegenden Kugellager läuft, das von der zur Einstellung des Mahlkegels dienenden üblichen Stellschraube getragen wird.Coffee grinder The invention relates to a coffee grinder, dr-ren grinding cones runs on a ball bearing located in it, which is used by the setting of the grinding cone serving usual adjusting screw is worn.
Nach der Erfindung ist das Kugellager des Mahlkegels ein diesen in axialer und radialer Richtung tragendes Schrägkugellager. Dadurch wirken nicht nur alle beim Mahlen auftretenden Kräfte auf die Kugeln des Kugellagers, es ist durch die nachstellbare kegelförmige Kugelgegenlage auch eine dauernd wirksame Zentrierung des Mahlkegels im Mahlring erreicht.According to the invention, the ball bearing of the grinding cone is one of these in axial and radial direction bearing angular contact ball bearings. This not only works all forces occurring during grinding on the balls of the ball bearing, it is through the adjustable, conical ball counter-support also provides a permanently effective centering of the grinding cone in the grinding ring.
Auf der Zeichnung ist als Ausführungsbeispiel der Erfindung das Mahlwerk einer Schoß- oder Kastenkaffeemühle im Längsschnitt dargestellt.In the drawing, the grinder is an embodiment of the invention a lap or box coffee grinder shown in longitudinal section.
Unter dem Deckela des Mahlkastens ist der Mahlring b durch den Bügel c und die diesen haltenden Schraubend befestigt. Die Schraubend halten auch den auf cdem Deckel a stehenden Bügele, der eine Lagerbüchse f hat, in der sich die Mahlwerkspindel g dreht. Auf dem unteren Ende der Mahlwerkspindel g sitzt fest der Mahlkegel h. Under the lid of the grinding box, the grinding ring b is fastened by the bracket c and the screw that holds it. The screw also hold the bracket standing on the cover a, which has a bearing bush f in which the grinder spindle g rotates. The grinding cone h sits firmly on the lower end of the grinder spindle g.
Die in dem Bügel c gelagerte SteU-schraube k zur Einstellung des Mahlkegels trägt an ihrer Spitze einen Lagerkegell mit kurvenförmiger Mantelfläche, auf welcher die von einem Käfig m gehaltenen Kugeln n des Kugellagers laufen. Der Lagerkonus mit seinen Kugellagerkugeln greift in eine schalenförmige Ausnehmung i der Unterseite des Mahlkegels; der so durch die Kugellagerkugeln und die Formen ihrer beiden Laufflächen in axialer und radialer Richtung durch das Kugellager geführt ist. Die Stellschraube k hat an ihrem unteren Ende einen Handhebel p, auf ihr sitzt ferner eine Schraubenfeder o, welche gegen den festen Bügel c und den Hebel p drückt und ein unbeabsichtigtes Verdrehen der Stellschraube verhindert.The control screw k mounted in the bracket c for setting the grinding cone has at its tip a bearing cone with a curved outer surface on which the balls n of the ball bearing, held by a cage m, run. The bearing cone with its ball bearing balls engages in a bowl-shaped recess i on the underside of the grinding cone; which is guided through the ball bearing balls and the shapes of their two running surfaces in the axial and radial directions through the ball bearing. The adjusting screw k has a hand lever p at its lower end, and a helical spring o is seated on it, which presses against the fixed bracket c and the lever p and prevents the adjusting screw from turning unintentionally.
Diese Kugellagerung des Mahlkegels ist mit gleichen Erfolge auch bei Wandkaffeemühlen anwendbar.This ball bearing of the grinding cone is also with the same success Wall coffee grinder applicable.
