Description

lagerung für Unruhwellen mit festem Locbstein und federnd gelagertem Deckstein. Die Erfindung betrifft eine Lagerung für Unruhwellen mit festem Lochstein und fe-, dernd gelagertem Deckstein. Das Neue besteht darin, daß die Feder durch ein in seiner Mitte den Deckstein erfassendesArmkreuz gebildet wird, dessen Arme an ihrer# freien Enden in Ausschnitte eines festgelagerten Tragringes radial zentriert eingreifen, derart, daß eine Verschiebung der Feder senkrecht zur Unruhwelle nur während der Federdurchbiegung möglich wird. Dadurch wird, der Vorteil erreicht, daß, im Gegensatz zu bisher bekannten Anordnungen, in der Ruhelage mit einer einzigen Feder eine vollkommene Sicherung der Unruhwelle gegen seitliche Kräfte erzielt wird, wobei aber eine Lockerung der Feder dann erreicht i#ird, wenn die Feder sich unter der Wirkung von achsialen, auf die Unruhwelle ausgeübten Kräften durchbiegt.Bearing for balance shafts with a fixed Locstein and a spring-loaded one Capstone. The invention relates to a bearing for balance shafts with a fixed perforated stone and spring-loaded capstone. The new thing is that the spring is through a cross is formed in its center, gripping the capstone, the arms of which at their # free ends radially centered in cutouts of a fixed support ring intervene in such a way that a displacement of the spring perpendicular to the balance shaft only becomes possible during spring deflection. This achieves the advantage that, in contrast to previously known arrangements, in the rest position with a single Spring a perfect protection of the balance shaft against lateral forces is achieved, but one Loosening of the spring is then achieved when the The spring is under the action of axial forces exerted on the balance shaft sags.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel der Erfindung. Abb. i ist eine Aufsicht auf die neue Lagerung der Un-, ruhwelle, Abb. 2 ein senkrechter Schnitt dadurch in größerem Maßstabe, Abb. 3 eine Auf -sicht auf die Feder, Abb. 4 eine Aufsicht auf die Fassung des Deckstei4es und Abb. 5 ein teilweise abgebrochen gezeichneter Aufriß des Tragringes.The drawing illustrates an embodiment of the invention. Fig. I is a plan view of the new bearing of the unsteady shaft, Fig. 2 is a vertical section through it on a larger scale, Fig. 3 is a plan view of the spring, Fig. 4 is a plan view of the socket of the cover piece and Fig 5 shows an elevation of the support ring, partially broken off.

Die Welle a der Unruhe b ist einerseits in der Unruhscheibe c und andererseits in der Scheibe d gelagert. Die Endzapfen der Unruhwelle a sind je in einem Lochsteid e, der in einem Ring J befestigt ist, gelagert. Gegen die Zapfenenden legt sich je ein Deck#-stein g, der gegebenenfalls in einer Fassung k mit einer mittleren Wulst kl untergebracht, ist. über die Wulst kl legt sich die mittlere öffnung 11 eines federnden Armkreuzes 1, dessen radiale Arme 12 in eine Nut kl eines festgelagerten Tragringes k radial zentriert eingreifen. Letzterer ist durch Schrauben k21 an der Platte c befestigt. Am unteren Zapfen der Unruhwelle a ist der Tragring k3, wel-# cher die Arme der Feder 1 in seiner Nut k:L aufnimmt, in die Platte d mit Gewinde eingeschraubt, so daß eine Verstellung, des unteren Decksteines in der Längsrichtung der Unruhwelle vorgenommen werden kann, Eine Schraube k4 dient zur Befestigung des Tragringes k3 in - der eingestellten Lage. Die federnden Armkreuze 1 können durch Einsprengen in die Nuten kl eingeführt werden.The shaft a of the balance b is mounted on the one hand in the balance disc c and on the other hand in the disc d. The end journals of the balance shaft a are each mounted in a perforated part e, which is fastened in a ring J. Against the shaft ends defines housed kl having an average bead depending on a deck # -stein g, k, where appropriate, in a version is. The middle opening 11 of a resilient spider 1, whose radial arms 12 engage radially centered in a groove kl of a fixed support ring k, lies over the bead kl. The latter is attached to the plate c by screws k21. On the lower pin of the balance shaft a, the support ring k3, which receives the arms of the spring 1 in its groove k: L, is screwed into the threaded plate d so that the lower cap stone is adjusted in the longitudinal direction of the balance shaft can be, k4 A screw is used to attach the support ring k3 in - the adjusted position. The resilient arm crosses 1 can be inserted into the grooves kl by being snapped into place.
