Einreihige Kugeldreliverbindung für hohe Drehzahlen.Single row ball reli connection for high speeds.
Die Heuerung bezieht sich auf eine einreihige Kugeldrehverbindung für hohe Drehzahlen, die als Vierpunktlager ausgebildet ist und einen geteilten Außenring aufweist. Die Kugeln werden durch einen Flachkäfig auf Abstand gehalten. Diese Bauart dient z.B. zur Lagerung der schweren Messerköpfe von Baumschälmaschinen, die eine Geschwindigkeit von 11-12 m/sek am Kugellaufkreis aufweisen.The hiring refers to a single-row slewing ring for high speeds, which is designed as a four-point bearing and has a split outer ring. The bullets will held at a distance by a flat cage. This type of construction is used, for example, to support the heavy cutter heads of tree peeling machines, which have a speed of 11-12 m / sec on the ball running circle.
Die bisher verwandte Bauform benutzte zwar ebenfalls eine Vierpunktbauweise, arbeitete jedoch die Laufbahnen zu einem normalen Rillenradius von 0,962 r aus. Abgesehen davon, daß dadurch ein verhältnismäßig großes Spiel gegeben war, entstanden beim Oberflächenhärten im Querschnitt auch WärmeStauungen, die eine gleichmäßige Härtung verhinderten. Diese Stauungen wurden hervorgerufen durch die Ecken, die infolge der Bauart in unmittelbarer Nähe der Laufbahnen an den Ringen entstanden und an denen die Wärme plötzlich abfloß, so daß eine gleichmäßige Härtung nicht zu erzielen war.The previously used design also used a four-point design, however, worked the raceways to a normal groove radius of 0.962 r. Aside from that there was a relatively large amount of play, there was also heat build-up during surface hardening in the cross-section prevented uniform hardening. These congestion were caused by the corners, which are in the immediate vicinity as a result of the design Near the raceways on the rings were created and where the heat suddenly flowed away, so that a uniform hardening could not be achieved.
Die !Teuerung beseitigt diese lachteile, indem sie den Rillenradius durch Hohlschleifen ungefähr gleich dem Kugelradius gestaltet und zwar wird ein Maß von etwa 0,999 r erreicht« Dadurch ist auch das Spiel sehr klein. Es wird ferner eine Erhöhung der Tragfähigkeit des Lagers insofern erzielt, als durchThe! Price rise eliminates this disadvantage by reducing the groove radius made roughly equal to the spherical radius by hollow grinding and a dimension of about 0.999 r is achieved the game is also very small. It is also achieved an increase in the load capacity of the bearing, as by
ein hohles Anschleifen der Schrägflächen keine Punktberührung sondern bereits eine Linienberührung zwischen Kugel und Laufbahn erzielt wird. Die Kugel wird an vier Stellen in einer Breite von etwa 10 mm von der Laufbahnrille umschlossen.a hollow grinding of the inclined surfaces no point contact but a line contact between the ball and the raceway is already achieved. The ball is in four places in one Width of about 10 mm enclosed by the raceway groove.
Infolge der Weiterführung der Schrägflächen des Lagers entfernen sich die Ecken von der Laufbahnrille 5 damit erhöht sich die Gleichmäßigkeit der Erwärmung, so daß die Härteverzüge sich verringern. Daraus ergibt sich wieder eine geringer werdende spanabhebende Nachbearbeitung.As a result of the continuation of the inclined surfaces of the bearing, the corners move away from the raceway groove 5 so that it increases the uniformity of the heating, so that the hardening distortions are reduced. This again results in a decreasing one machining post-processing.
Ein Ausführungsbeispiel der Eugeldrehverbindung gemäß der Neuerung ist in der Zeichnung im Querschnitt dargestellt.An embodiment of the Eugel slewing ring according to FIG The innovation is shown in cross section in the drawing.
In der AbbildungK bezeichnet 1 den Innenring und 2, 2' den geteilten Außenring. Letzterer ist mittels nicht dargestellterIn the figure K, 1 denotes the inner ring and 2, 2 'denotes the split one Outer ring. The latter is not shown by means of
Schrauben in den Bohrungen 3 zusammen gehalten, wobei Ver— Schleißerscheinungen durch Nachstellen ausgeglichen werden können. Die Kegeln 4 werden mittels Kugelkäfigen 5 auf Abstand gehalten.Screws held together in the holes 3, whereby ver- Signs of wear can be compensated for by readjusting. The cones 4 are spaced apart by means of ball cages 5 held.
In den Schrägflächen 6 des Lagers sind etwa mittig die Laufrillen 7 eingeschliffen. Durch Weiterführung der Schrägflächen werden die Ecken 8 bzw. 8' von der Laufrille abgesetzt, so daß sie beim Oberflächenhärten keinen nachteiligen Einfluß auf die Gleichmäßigkeit der Erwärmung der Laufrillenumgebung ausüben können.In the inclined surfaces 6 of the bearing, the grooves 7 are ground approximately in the middle. By continuing the inclined surfaces the corners 8 and 8 'are set off from the running groove, so that they have no adverse effect on surface hardening can exert the uniformity of heating of the raceway environment.
