Abstract

The device for securing a hub to a shaft comprises a pair of collars seated ina groove of the shaft. The mutually remote faces of the collars are square to the shaft axis and bear against the one shoulder of the groove and an opposite end face of the hub. The confronting faces of the collars are oblique so that on relative rotation of the collars, the faces are urged apart and apply an axial force to the hub. To avoid undue friction at the oblique surfaces the collars are made of material e.g. a plastic having good sliding properties.

Description

Vorrichtung zum axialen Verspannen von dreh- oder/und längsbeweglich angeordneten Teilen wie Ringen, I3üchsen, Lagern, Muttern.Device for the axial bracing of rotatable and / or longitudinally movable arranged parts such as rings, sleeves, bearings, nuts.

Die Erfindung betrifft einen Sicherungsring, mit welchem es möglich ist, auf einer Welle oder in einer Bohrung sich befindende Maschinenteile axial starr zu verspannen.The invention relates to a locking ring with which it is possible machine parts located on a shaft or in a bore are axial to be rigidly braced.

Dies wird dadurch erreicht, dass zwei hintereinander angeordnete Sicherungsringe auf einer Welle oder in einer Bohrung durch Sitz in einer Nut eine Schulter wilden und dadurch Naschinenteile axial festlegen. ie Sicherungsringe sind offen, um über eine Welle geschoben bzw. in eine Bohrung eingebracht werden zu könen.This is achieved by having two securing rings arranged one behind the other wild a shoulder on a shaft or in a hole by seating in a groove and thereby fix machine parts axially. he retaining rings are open to over a shaft can be pushed or inserted into a hole.

Sie sind über ihren Umfang nicht gleich dick, sondern ihre beiden lslanseiten sind so ausgebildet, dass eine dieser Seiten in gestrecktem Zustand eine schiefe Ebene bildet.They are not equally thick about their circumference, but both of them Islanseiten are designed so that one of these sides is in the stretched state forms an inclined plane.

Die beiden Sicherungsringe sind in der Nut so angeordnet, dass ihre schiefe ebene aneinander zur Anlage kommt. IJie beiden anderen Planseiten sind nun parallel zur Schulter des Einstiche bzw.The two locking rings are arranged in the groove so that their inclined plane comes to rest against each other. The other two sides of the plan are now parallel to the shoulder of the puncture or

um Maschinenteil auf der Welle bzw. in der Bohrung. i)abei ist die ut so bemessen, dass sie breiter ist als die gemeinsame Dicke der beiden Sicherungsringe. Deshalb kommt im eingebauten die Planseite des einen Sicherungsringes an der Schulter des instiches, die Planseite des anderen Sicherungsringes an dem zu verspannenden Maschinenteil zur Anlage.around the machine part on the shaft or in the bore. i) this is the one ut sized so that it is wider than the combined thickness of the two retaining rings. That is why the flat side of one of the locking rings is installed on the shoulder des instiches, the flat side of the other locking ring to be braced Machine part for the system.

@erden nun die beiden Sicherungsringe geseneinander verdreht, so vergrössert sich die Gesamtdicke auf Grund der schiefen @bene. Dadurch ist es möglich, Laschinenteile auf einer welle bzw in einer Bohrung gegen einen JSund oder dergleichen zusammenzuspannen. @earth the two circlips twisted together, like this the total thickness increases due to the inclined plane. This makes it possible Lashing parts on a shaft or in a hole against a JSund or the like to clamp together.

solche Sicherungsringe sind bekannt @ie werden jedoch nicht hergestellt, weil als sierkstoff @tahl vorgesehen ist und es daher nicht möglich ist, die schiefe ebene nit einer solchen Oberfläche zu versehen, die notwendig ist, um einen solch kleinen @eibunskoeffizienten zu erhalten, dass mit einer kleinen Drehkraft eine grosse Axialkraft erzeugt werden kann.such circlips are known @ they are not manufactured, because @tahl is intended as sierkstoff and it is therefore not possible to use the crooked to provide a flat surface with a surface that is necessary for such a small @eibun coefficients to get that with a small torque a large axial force can be generated.

Der Erfindung liegen solche Sicherungsringe zu Grunde. Um jedoch bei kleiner Drehkraft einen grossen Axialdruck zu erzeugen, ist es notwendig, den Reibungskoeffizienten der schiefen Ebene sehr klein zu halten. Dieser ist aber nicht nur von der Rauhtiefe der Reibungsflächen, sondern hauptsächlich vom Werkstoff selbst abhängig.The invention is based on such retaining rings. However, in order to small torque to generate a large axial pressure, it is necessary to adjust the coefficient of friction to keep the inclined plane very small. But this is not only due to the roughness the friction surfaces, but mainly depends on the material itself.

Erfindungsgemäss sind daher die Sicherungsringe aus einem Werkstoff gefertigt, der gute Gleiteigenschaften aufweist und der sich fiir die Massenfertigung solcher Sicherungsringe eignet.According to the invention, therefore, the retaining rings are made of one material manufactured, which has good sliding properties and which is suitable for mass production such retaining rings are suitable.

»uch muss er eine solche Elastizität besitzen, dass ein geringes Aufspreizen der Sicherungsringe möglich ists um sie über eine Welle zu führen. Dieser Werstoff kann z.B. Kunststoff sein.»It must also have such elasticity that it can only be spread slightly the circlips is possible to guide them over a shaft. This material can e.g. be plastic.

Die Sicherungsringe nach DIN 471 sind aus Federstahl und so gestaltet, dass sie, auf einer Welle montiert, durch di c kraft nicht abgeschleudert werden können. Diese Gefahr besteht, weil sie lose in der Wellennut liegen. @in Abschleudern von der @elle ist bei den Sicherungsringen nach der Erfindung nicht möglich, weil sie axial verspannt sind. die Schiefe bene der Sicherungsringe muss kleiner als 40 sein, um in jedem falle Selbsthemmung zu gewährleisten. Durch diese kleine Steigung der schiefen ebene kann durch Verdrehen der beiden Sicherungsringe gegeneinander mit kleinem Kraftaufwand eine grosse @xialkraft zum Verspannen der Maschinenteile erzeugt werden.The circlips according to DIN 471 are made of spring steel and designed in such a way that that they, mounted on a shaft, are not thrown off by the force can. This danger exists because they are loose in the shaft groove. @in throwing off of the @elle is not in the circlips according to the invention possible because they are axially braced. the obliqueness of the locking rings must be be less than 40 to ensure self-locking in every case. Through this small incline of the inclined plane can be achieved by turning the two locking rings against each other with little effort a large @xialkraft to brace the Machine parts are generated.
