Description
dem Gehäuse 1 hervor.the housing 1 emerges.
Die Druckkammern 7 liegen im Spannelement annähernd in derselben Radialebene axial hinter der Druckkammer 16.The pressure chambers 7 are located in the clamping element in approximately the same radial plane axially behind the pressure chamber 16.
Die Hohlräume der Druckkammern 7 und 16 sowie die diese Hohlräume miteinander verbindenden Kanäle 14 sind mit einem Hydraunkmedium gefüllt Beim Einschrauben der Druckschrauben 8 in die Druckkammer 7 wird mit Hilfe des Kolbens 11 über das Hydraulikmedium ein Druck auf die Dichtlippe 18 und damit auf den Ringkolben 19 ausgeübt, welcher sich aus dem Gehäuse I heraus, in Fig.2 nach rechts, verschiebt Wie aus F i g. 2 hervorgeht wird der Ringkolben 19 dabei gegen das anzupressende Maschinenteil, z. B. gegen einen auf einer Maschinenwelle 22 Ln axialer Richtung frei verschieblichen Wälzfräser 23 angepreßt Der Anpreßdruck kann dabei durch die Einschraubtiefe der Schrauben 8 in die Druckkammern 7 eingestellt werden.The cavities of the pressure chambers 7 and 16 and the channels connecting these cavities to one another 14 are filled with a hydraulic medium when the pressure screws 8 are screwed into the pressure chamber 7 a pressure is exerted on the sealing lip 18 and thus on the with the aid of the piston 11 via the hydraulic medium Annular piston 19 exerted, which moves out of the housing I, to the right in FIG F i g. 2 shows the annular piston 19 against the machine part to be pressed, for. B. against one a machine shaft 22 Ln the axial direction freely displaceable hob 23 pressed The contact pressure can be adjusted by the screwing depth of the screws 8 in the pressure chambers 7.
Es ist möglich, an dem Spannelement mehr oder weniger als drei Druckkammern vorzusehen, deren Achsen entlang von Sekanten verlaufen.It is possible to more or less on the clamping element than to provide three pressure chambers, the axes of which run along secants.
Beim Einschrauben der Druckschrauben 8 in die Druckkammern 7 wirkt der erzeugte hydraulische Druck auch auf die Kolben 30,31 der Druckanzeige, so daß sich der Anzeigestift 25 mit dem Kolben 31 unter Spannung des Federpakets 29 entsprechend verschiebt Die Ablesung der Druckanzeige erfolgt über geeichte Meßringe 33 am Anzeigestift 25.When the pressure screws 8 are screwed into the pressure chambers 7, the hydraulic pressure generated acts Pressure also on the pistons 30,31 of the pressure indicator, see above that the indicator pin 25 moves with the piston 31 under tension of the spring assembly 29 accordingly The pressure display is read off via calibrated measuring rings 33 on the display pin 25.
Am Gehäuse 1 sind radiale Sackbohrungen 24 vorgesehen, in die ein Spannschlüssel eingesetzt werden kann, wenn das Spannelement auf der Maschinenwelle 22 festgeschraubt weiden soll.Radial blind bores 24 are provided on the housing 1, into which a wrench can be inserted. when the clamping element is to be screwed tightly onto the machine shaft 22.
