Description

Kurvenscheibe aus elektrisch isolierendem Stoff Es ist bekannt, Kurvenscheiben, die zur Betätigung elektrischer Schaltapparate dienen, aus mechanisch festem Isolierstoff herzustellen und auf eine kantige Metallachse aufzuschieben. Da die Festigkeit auch der harten Isolierstoffe aber immerhin beschränkt ist, werden die Kuirvenscheiben, die in größerer Zahl für einen einzigen elektrischen Schaltapparat gebraucht werden, nach der Erfindung nicht unmittelbar auf die Schaltwelle aufgeschoben, sondern einzeln auf je eine eigene Metallhülse mit kantiger Kontur aufgepreßt, die ihrerseits undnehbar auf der Schaltwelle befestigt werden kann.Cam disk made of electrically insulating material It is known to produce cam disks, which are used to actuate electrical switching devices, from mechanically strong insulating material and to push them onto an angular metal axis. Since the strength is also the hard insulating materials but still limited, the Kuirvenscheiben that are needed in large numbers for a single electrical switch apparatus, pushed by the invention does not directly to the selector shaft but separately on each own metal sleeve pressed with edged contour, which in turn can be attached to the selector shaft in a non-removable manner.

Zwei derartige Scheiben, für selektrische Kontroller bestimmt, sind in der Zeichnung als Ausführungsheäspiele für die Erfindung dargestellt. Abb. i zeigt eine Kurvenscheibe aus Isolierstoff a im Schnitt, die auf die rund ausgebohrte Sechskantnabe b mit Loche für de Versstiftung mit der Kontrollerwelle aufgepreßt ist. Die Nabe b ist mit einer Rille c versehen, in die das Is,ohermateriial hineingep,reßt ist, so daß eine Achsialverschiebung ausgeschlossen isst. Abb. z zeigt die Scheiben in der Draufsicht; sie ist mit einer e'ngepreßten Gradeinteilung versehen,, durch die die Montage der verschiedenlen Kurvenscheiben auf der Sschaltwelle wesentlich erIeichtert wird. In Abb.3 wird die Scheibe a durch einen Bund d am Umfang der - Nahe b, . um. den das Isoliermaterizl herumgeprießt ist, an einer Achsialverschiebung verhindert.Two such discs, intended for selective controllers, are shown in the drawing as execution games for the invention. Fig. I shows a section of a cam disk made of insulating material a, which is pressed onto the round bored hexagonal hub b with holes for pinning with the controller shaft. The hub b is provided with a groove c into which the thermal material is torn, so that axial displacement is ruled out. Fig. Z shows the disks in plan view; it is provided with a pressed-in graduation through which the assembly of the various cam disks on the switch shaft is made considerably easier. In Fig.3, the disk a is supported by a collar d on the circumference of the - near b,. around. that the Isoliermaterizl is pressed around, prevented from an axial displacement.
