Description

i Zum Einbau des Drehzapfens 4 wird dieser bei I noch nicht eingesetzter Hülse 10 so weit durch den j Bund 9 hindurchgeführt, bis das Drehzapfenende 12 I in der Hülse 7 liegt. Dann wird die Hülse 10 von unten so weit über den Drehzapfen 4 geschoben, bis sie i in dem Bund 9 liegt und die Verjüngung 15 des Drehzapfens 4 zunächst lose umfaßt. Darauf wird eine Scheibe 13 von unten über den Drehzapfen 4 geschoben und mit Schrauben 14 auf dem Bund 9 verschraubt. Mit zunehmendem Einschrauben der Schrauben 14 drückt die Scheibe 13 die Hülse 10 in den Bund 9 und den Drehzapfen 4 in die Hülse 7.i To install the pivot 4 this is not yet inserted at I sleeve 10 so far through the j collar 9 passed through until the pivot end 12 I lies in the sleeve 7. Then the sleeve 10 from below pushed so far over the pivot 4 until it is i in the collar 9 and the taper 15 of the Trunnion 4 initially loosely included. A disk 13 is then pushed over the pivot 4 from below and screwed to the collar 9 with screws 14. With increasing screwing in of the Screws 14, the washer 13 presses the sleeve 10 into the collar 9 and the pivot 4 into the sleeve 7.

Die Schrauben 14 werden so weit eingeschraubt, daß die Verjüngung 15 des Drehzapfens 4 radial spiellos gehalten ist. Etwaige Paßungenauigkeiten oder Abnutzungen werden durch das Maß des Anziehens der Schrauben 14 ausgeglichen. Der Drehzapfen 4 wird zentrisch in die Hülsen und Bunde der beiden Lager eingeführt, so daß er nicht in seinen Lagern verkantet ist.The screws 14 are screwed in so far that the taper 15 of the pivot pin 4 has no radial play is held. Any inaccuracies in fit or wear and tear are determined by the degree of tightening of the Bolts 14 balanced. The pivot 4 is centered in the sleeves and collars of the two bearings introduced so that it is not jammed in its bearings.
