Description

Auch die Klemmplatten b und V können zur Unterstützung der Kühlwirkung mit der Scheibe einen Luftspalt bilden mittels der Unterlagen h, h'. Dieser Luftspalt kann seine Luftzuführung erhalten durch besondere Öffnungen k, k'. The clamping plates b and V can also form an air gap with the pane by means of the supports h, h 'to support the cooling effect. This air gap can receive its air supply through special openings k, k '.

Luftgekühlte Schleifscheibe für Trockenschliff, dadurch gekennzeichnet, daß der Schleifzylinder aus mehreren, mit Zwischenraum (Abstandsstücke g) nebeneinander angeordneten Ringscheiben (a, a') besteht, die durch seitliche, in den Hohlraum mit zentrierenden Ansätzen angreifende Klemmplatten (b, b') mit Öffnungen (/, f) für den Luftzutritt in den Hohlraum mit der Welle (c) befestigt sind, so daß beim Umlauf der Scheibe infolge der Zentrifugalkraft in dem Raum zwischen den einzelnen Schleifringteilen ein Luftstrom entsteht, der kühlend auf Werkzeug und Werkstück wirkt.Air-cooled grinding wheel for dry grinding, characterized in that the grinding cylinder consists of several ring disks (a, a ') arranged next to one another with a gap (spacers g) , which are joined by lateral clamping plates (b, b') engaging in the cavity with centering lugs Openings (/, f ) for air entry into the cavity are attached to the shaft (c), so that when the disk rotates due to the centrifugal force in the space between the individual slip ring parts, an air flow is created that has a cooling effect on the tool and workpiece.

Patentanspruch:Claim: kann. Die einzelnen Ringscheiben sind mit einem schmalen Zwischenraum aufgebracht, dessen Größe zweckmäßig durch Beilagen g, g', g" bestimmt wird. Es entsteht also 'beim Umlauf des Schleifzylinders in dem Raum zwischen den einzelnen Schleifringscheiben ein Luftstrom ähnlich wie bei Schleuderscheiben eines Zentrifugalgebläses; die Außenluft tritt, wie durch Pfeil angedeutet, durch die Öffnungen f, f ein und strömt zwischen die Scheiben hindurch, wobei sie kühlend auf Werkzeug und Werkstück wirkt.can. The individual ring disks are applied with a narrow gap, the size of which is appropriately determined by enclosures g, g ', g " . Thus, when the grinding cylinder rotates in the space between the individual slip ring disks, an air flow similar to that of the centrifugal disks of a centrifugal blower arises As indicated by the arrow, outside air enters through openings f, f and flows between the panes, where it has a cooling effect on the tool and workpiece. Die in den Abbildungen dargestellte Ausführungsform der Scheiben läßt nur zwei einfache Ringscheiben α und a' erkennen. Es ist natürlich ohne weiteres möglich, unter Anwendung durchbrochener Zentrierkörper die Anzahl der Scheiben beliebig zu erhöhen.The embodiment of the disks shown in the figures shows only two simple annular disks α and a ' . It is of course easily possible to increase the number of disks as desired using perforated centering bodies.
