Bolzensicherung insbesondere zur Lagerung von Kolbenbolzen in Kolben-Naben für insbesondere Schnell-Laufende Kompressoren oder Verbrennungsmotoren etc.Bolt retainer, particularly for the storage of piston pins in piston hubs for particularly high-speed compressors or combustion engines etc.

Als Grenzdrehzahlen werden die Drehzahlen definiert, bei denen die Massenkraft die Vorspannung gerade aufhebt bzw. die Einfederung der sogenannten Sprengringe am höchsten Punkt, der Ringnut-Tiefe entspricht. The speed limits are defined as the speeds at which the mass force just cancels out the preload or the deflection of the so-called snap rings at the highest point corresponds to the ring groove depth.

Vielerorts liegt diese Grenzdrehzahl im Drehzahl-Bereich heutiger Motoren und Kompressoren.In many places, this limit speed is within the speed range of today’s engines and compressors.

Deshalb werden herkömmliche Federringe aus den Ring-Nuten ausgeschlagen bzw. federn diese Federringe aus den Ringnuten aus.This is why conventional spring rings are knocked out of the ring grooves or these spring rings spring out of the ring grooves.

Um hier Abhilfe zu schaffen dient die vorliegende Neuerung. Erfindungsgemäß wird ein Ausschlagen oder Ausfedern dadurch verhindert, daß die Federringe (aus Federstahl ausgestanzt); Im Scheitel gesickt sind. Ohne die herkömmlichen Ringquerschnitte zu erhöhen, werden die Eigen-Spannkräfte bis 60 % erhöht.The present innovation is intended to remedy this situation. According to the invention, deflection or springing is prevented by the spring rings (punched out of spring steel) being beaded at the apex. Without increasing the conventional ring cross-sections, the inherent clamping forces are increased by up to 60 % .

Um die Sprengringe mit rechteckigem Querschnitt aus- bzw. einbauen zu können, sind die Ringenden nach innen hochgebogen bzw. für den Eingriff einer Zange gelocht ausgeführt. Durch die "Einbauchung" im Scheitel können die Querschnitte des Ringes dort verkleinert werden. Fig. 1 zeigt ein Ausführungsbeispiel des Neuerungs-Gedanken.In order to be able to remove or install the snap rings with a rectangular cross-section, the ring ends are bent upwards or perforated so that pliers can grip them. The "indentation" at the apex allows the cross-sections of the ring to be reduced there. Fig. 1 shows an example of the innovative idea.

Der Sprengring 1 ist im Scheitel 2 gesickt S die Enden 3,3', weisen Löcher 4,4' auf in die z. B. eine Zange zwecks (DE)-Montage eingreifen kann.The snap ring 1 is beaded at the apex 2 S the ends 3,3' have holes 4,4' into which, for example, a pair of pliers can engage for (DE) assembly.

Fig. 1 A zeigt ein weiteres Beispiel. Die Enden des Ringes E, E1 sind nach innen gerollt, sodaß wiederum eine Vorkehrung entsteht durch die (V) der Ring montiert bzw. demontiert werden kann.Fig. 1 A shows another example. The ends of the ring E, E1 are rolled inwards, so that another provision is created through which (V) the ring can be mounted or dismounted.

Der Ring wird dadurch leichter.This makes the ring lighter.

Fig. 2 zeigt ein leichtgewichtigen Ring in CO 'OMEGA' - FORM nach derFig. 2 shows a lightweight ring in CO 'OMEGA' - FORM after the

Claims (1)

ANSPRUCHCLAIM Bolzensicherung insbesondere für Kolbenbolzen, bei der ein offener in sich federnder schmaler Ring mit vorzugsweise kreisförmigem Querschnitt in eine entsprechende Ringnute so eingefedert bzw. eingesprengt ist, daß er aus der Nut so weit herausragt, daß für den Bolzen Anschlagflächen geschaffen sind, durch die eine seitliche Verschiebung des Bolzens in seiner Nut verhindert bzw. eingegrenzt wird, wobei der Ring an vorzugsweise beiden Enden Vorkehrungen z. B. Löcher besitzt in die eine Zange greifen kann und der Ring (de)montiert werden kann.Bolt lock, particularly for piston pins, in which an open, springy narrow ring with a preferably circular cross-section is sprung or snapped into a corresponding ring groove in such a way that it protrudes from the groove so far that stop surfaces are created for the bolt, which prevent or limit lateral displacement of the bolt in its groove, whereby the ring preferably has provisions at both ends, e.g. holes into which pliers can grip and the ring can be (dis)assembled. Dadurch gekennzeichnet, daß der Ring CO -(OMEGA) förmig ausgebildet d. h. im Scheitel gegenüber den Enden 3,3', E1, E eingebaucht (ausgestanzt) ist.Characterized in that the ring is CO -(OMEGA) shaped, ie it is dented (punched out) at the apex opposite the ends 3,3', E1, E.
