Description
Schaltwalze aus keramischen Stoffen oder Preßmaterialien für Drehschalter Bei Drehschaltern mit Schaltwalzen; ist eine Verdrehungsmöglichkeit zwischen Walze und in ihr befindlicher Welle erforderlich. Z«rischen diesen beiden Organen ist die Fortschnellfeder- ein,geschältet, welche durch Drehung am Nebel gespannt die Schaltwalze nach der Freigabe ihrer Sperrfedern bis zum nächsten Rastenanschlag dreht. Ist die Scbaltwalze aus keramischen Stoffen hergestellt, so ist es erforderlich, daß zwischen. den Konstruktionsteilen genügend Luft ist; denn die Fabrikation - verlangt größere Toleranzen als bei Metallteilen. Die Folge davon ist, daß sich die Schaltwalze auf der Welle unter Umständen verkanten und einseitig abnutzen kann. Man hat. daher den aus keramischen Stoffen oder Preßmaterialien bestehenden Schaltwalzen metallische Stirnflächen gegeben, um die Achse mit ganz geringem Spielraum durchführen zu können.Shift drum made of ceramic materials or pressed materials for rotary switches For rotary switches with switching drums; is a possibility of rotation between the roller and the shaft in it is required. There is a problem with these two organs the rapid spring, peeled, which tensioned by turning the fog Shift drum after releasing its locking springs to the next detent stop turns. If the switch roller is made of ceramic materials, it is necessary to that between. there is enough air in the construction parts; because the manufacture - requires greater tolerances than metal parts. The consequence of this is that the shift drum on the shaft may tilt and wear on one side. One has. hence the shift drums made of ceramic materials or molding materials given metallic end faces to perform around the axis with very little play to be able to.
Die Erfindung besteht nun darin, eine der Stirnplatten als Sperrfeder auszubilden, wie dieses die Abb. i und 2 erkennen lassen. Diese Sperrfeder legt sich in dem Ausführungsbeispiel gegen einen Vorsprung eines die Schaltwalze übergreifenden Bügels und wird nach einer bestimmten Drehung der Schalterwelle durch Niederdrücken ausgelöst. In den Abbildungen bezeichnet 8 die Schaltwalze, welche auf der hohlen. Welle drehbar gelagert ist und auf der einen Stirnfläche eine Führungsscheibe 2, auf der anderen die als solche ausgebildete Sperrscheibe i erhält. Diese beiden Scheiben sind durch Nieten oder Schrauben 9 an. der Schaltwalze befestigt.The invention now consists in using one of the end plates as a locking spring train, as this can be seen in Figs. i and 2. This locking spring attaches in the embodiment against a projection of a shift drum overlapping Bracket and is pressed after a certain rotation of the switch shaft triggered. In the figures, 8 denotes the shift drum, which is on the hollow. Shaft is rotatably mounted and on one end face a guide washer 2, on the other, the locking disk i designed as such receives. These two Washers are attached by rivets or screws 9. attached to the shift drum.
Um die Fortschnellfeder 5, welche in Abb.3 getrennt abgebildet ist, mitsamt der hohlen Welle 3 nach dem Aufnieten der Stirnplatten in die Schaltwalze 8 einführen zu können, wird die Sperrfederplatte i mit einer schlitzförmigen Offnung q. versehen und durch diese die Schenkel der Fortschnellschraubenfeder 5' eingeführt.To use the rapid spring 5, which is shown separately in Fig. together with the hollow shaft 3 after riveting the end plates into the shift drum 8 to be able to introduce the locking spring plate i with a slot-shaped opening q. provided and inserted through this the legs of the rapid coil spring 5 '.
