   Wird dagegen Zahnkranz 23 gedreht, so muss naturgemäss eine Relativbewegung der Welle 7 gegen Welle 2 erfolgen und dadurch eine Verstellung des Werkzeugträgers herbeigeführt werden. 



   PATENT. ANSPRÜCHE :
1.   Bohr- und Schleifm. 8chine   mit während des Betriebes veränderbarem Durchmesser des vom Werkzeug beschriebenen Kreises, dadurch gekennzeichnet, dass die Bohrwelle (2) und die darin konzentrisch gelagerte Einstellspindel   (7)   gleiche Aussenverzahnung   (24,   25) besitzen, in welche zwei Räder (26, 27) von gleichem Durchmesser eingreifen, die mittels eines Halters   (28)   um die Achse der   Bohrwelle (2) heisen uud welche   andererseits in zwei Radkränze   (22,     2.   mit gleicher Innenverzahnung eingreifen, von denen der eine gegen den anderen verstellt werden kann, wodurch eine Relativbewegung der Einstellspindel (7) gegen die Bohrwelle (2)

   herbeigefÜhrt wird und dass ferner die Einstellspindel an ihrem anderen Ende ein Zahnrad   (15)   trägt, welches in einen exzentrisch dazu an der Bohrwelle   (2)   drehbar angeordneten und mit dem Werkzeugträger   (12)   in fester Verbindung stehenden Innenzahnkranz   (14)   eingreift.

   If, on the other hand, the ring gear 23 is rotated, a relative movement of the shaft 7 with respect to the shaft 2 must naturally take place, thereby causing an adjustment of the tool carrier.



   PATENT. EXPECTATIONS :
1. Drilling and grinding machine 8chine with variable diameter of the circle described by the tool during operation, characterized in that the drilling shaft (2) and the adjusting spindle (7) mounted concentrically therein have the same external toothing (24, 25) in which two wheels (26, 27) of the same diameter, which by means of a holder (28) around the axis of the drilling shaft (2) and which, on the other hand, engage in two wheel rims (22, 2) with the same internal toothing, one of which can be adjusted against the other, creating a relative movement the setting spindle (7) against the drilling shaft (2)

   is brought about and that the adjusting spindle also carries a gear (15) at its other end, which engages in an internal gear rim (14) which is rotatably arranged eccentrically thereto on the drilling shaft (2) and which is firmly connected to the tool carrier (12).

Claims (1)

2. Maschine nach Anspruch 1, dadurch gekennzeichnet, dass innerhalb der Einstellspindel (7) konzentrisch die Spindel (8) gelagert ist, welche zum Antrieb der exzentrisch gelagerten Schleifspindel (9) dient. 2. Machine according to claim 1, characterized in that the spindle (8), which serves to drive the eccentrically mounted grinding spindle (9), is mounted concentrically within the adjusting spindle (7).
