Description
Die Erfindung betrifft ein Verfahren zur Herstellung einesThe invention relates to a method for producing a
aus Kunststoff bestehenden Wälzkörperhalters, der durch eine Wälzkörperführung und durch Wälzkörper gebildet ist, Ferner betrifft die Erfindung eine Einrichtung in Form eines Spritzgußwerkzeuges zur Durchführung des Verfahrens, einen nach dem Verfahren hergestellten Wälzkörperhalter und eine spezielle Verwendung desselben.Rolling element holder made of plastic, which is supported by a rolling element guide and is formed by rolling elements. The invention also relates to a device in the form of an injection molding tool to carry out the process, one after Process produced rolling element holder and a special use of the same.
Bei bisher bekannten Wälzkörperhaltern, die als Lagerelemente in Rädern und Rollen Verwendung finden, ist die Wälzkörperführung aus Kunststoff hergestellt, während die Wälzkörper meistens aus Stahl gefertigt sind. Beide Teilearten erfordern unterschiedliche Fertigungsmethoden, die als bekannt vorausgese#tzt werden dürfen. Der Zusammenbau dieser Teile zum fertigen Wälzkörperhalter muß in einem weiteren Arbeitsgang vorgenommen werden. Eine solche Art der Herstellung ist aufgrund der verschiedenen Arbeitsgänge relativ kostenintensiv. Oft müssen diese Teile dann vor ihrer Montage noch zwischengelagert werden, da in Betrieben gewöhnlich die Kunststoffteilefertigung und die mechanische Fertigungsabteilung zur Herstellung der Wälzkörper räumlich auseinander liegen. Dies verursacht ebenfalls Kosten.In previously known rolling element holders, which are used as bearing elements in wheels and rollers are used, the rolling element guide is made of plastic, while the rolling elements are mostly made of steel. Both types of parts require different manufacturing methods that can be assumed to be known. The assembly of these parts to the finished rolling element holder must be done in a further Operation to be carried out. Such a way of manufacture is due to the different operations relatively cost-intensive. Often these parts then have to be applied their assembly are still temporarily stored, since in factories usually the plastic parts production and the mechanical production department for the production of the rolling elements to be apart. This also incurs costs.
Die Aufgabe der vorliegenden Erfindung besteht somit darin, ein Verfahren und eine Einrichtung zur Herstellung eines Wälzkörperhalters der eingangs genannten Art zu entwickeln, bei dem die Anzahl der erforderlichen Arbeitsgänge gegenüber dem bisher bekannten Stand der Technik weiter verringert wird und ein Zwischenlagern der einzelnen Bauteile entfällt.The object of the present invention is therefore to provide a method and a device for producing a rolling element holder of the type mentioned at the beginning Kind of develop in which compared to the number of operations required the previously known prior art further reduced will and there is no need for intermediate storage of the individual components.
Die Aufgabe ist erfindungsgemäß dadurch gelöst, daß die Wälzkörper und die Wälzkörperführung als ein Teil gespritzt werden und daß nach erfolgtem Spritzvorgang, während des Öffnens des Spritzgußwerkzeuges, die Wälzkörper durch die Einwirkung von axial gerichteten Schubkräften und der dadurch in den Ringabschnitten sich bildenden Scherkräfte von der Wälzkdrperfjji'rung getrennt und auf an der Wä.lzkörperführung befindliche Zapfen gedrückt werden.The object is achieved according to the invention in that the rolling elements and the rolling element guide are injected as one part and that after the injection process has taken place, during the opening of the injection molding tool, the rolling elements by the action of axially directed thrust forces and the resulting in the ring sections Shear forces are separated from the rolling element perfection and applied to the rolling element guide located pins are pressed.
Dank dieses vorteilhaften Verfahrens ist es möglich, in einem Arbeitsgang und mit einem einzigen Spritzgußwerkzeug sowohl die Wälzkörper, als auch die Wälzkörperführung herzustellen und zusammenzufügen, sodaß der Wälzkörperhalter nach Beendigung des Spritz- und Auswerfvorganges gebrauchsfertig zur Verfügung steht.Thanks to this advantageous process, it is possible in one operation and with a single injection molding tool both the rolling elements and the rolling element guide manufacture and assemble, so that the rolling element holder after completion of the Injection and ejection process is ready to use.
Die Erfindung wird aiiliand eines bevorzugten Ausführungsbeispieles näher beschrieben.The invention forms part of a preferred embodiment described in more detail.
Es zeigt Fig. 1 in einem Schnitt und in einer Teilansicht einen Wälzkörperhalter; Fig. 2 bis Fig. 4 drei Verfahrensschritte zur Herstellung des Wälzkörperhalters, sowie Fig. 5 einen Anwendungsfall für einen Wälzkörperhalter.1 shows a rolling element holder in a section and in a partial view; FIGS. 2 to 4 show three method steps for producing the rolling element holder, and FIG. 5 shows an application for a rolling element holder.
Der in Fig. 1 dargestellte Wälzkörperhalter 1 besteht aus einer Wälzkörperführung 2 und darauf gelagerten zylindrischen oder kegeligen Wälzkörpern 6. Die Wälzkörperführung 2 ist als Ringkörper 3 gestaltet, bei dem an einer Seite in gleichmäßigen Abständen und parallel zur Längsachse des Ringkörpers 3 verlaufend, zylindrische Zapfen 4 angeformt sind, auf welchen die Wälzkörper 6 beweglich gelagert sind. Die axiale Begrenzung der Wälzkörper 6 erfolgt an den freien Zapfenenden durch je einen Bund 5 und zur anderen Seite hin durch den Ringkörper 3. Wälzkörperführung 2 und Wälzkörper 6 sind zweckmäßigerweise aus Polyamid gefertigt.The rolling element holder 1 shown in Fig. 1 consists of a rolling element guide 2 and cylindrical or tapered rolling elements mounted on it 6. The rolling element guide 2 is designed as an annular body 3, in which on one side at regular intervals and parallel to the longitudinal axis of the ring body 3, cylindrical pins 4 are formed on which the rolling elements 6 are movably mounted. The axial The rolling elements 6 are delimited at the free journal ends by a collar each 5 and to the other side through the ring body 3. Rolling element guide 2 and rolling elements 6 are expediently made of polyamide.
Die Figuren 2 bis 4 beschreiben das Verfahren zur Herstellung des Wälzkörperhalters 1. Das dafür notwendige Spritzgußwerkzeug 7 weist Merkmale und Bauteile auf, die in der Spritzgußtechnik geläufig sind. Deshalb sind in der nachfolgenden Beschreibung anhand eines Wälzkörperbereiches nur jene Teile aufgeführt, die zur Erklärung des Verfahrensablaufes notwendig sind.Figures 2 to 4 describe the method for producing the Rolling element holder 1. The injection molding tool 7 required for this has features and Components that are common in injection molding technology. That is why in the following Description based on a rolling element area, only those parts are listed that are used for Explanation of the process sequence are necessary.
Das Spritzgußwerkzeug 7 besteht aus einem starren Formblock 8, der auch die Angüsse 19 beinhaltet, sowie aus einem beweglichen Formblock 9. Im Formblock 9 sind Formen 10 zur Bildung der Wälzkörper 6 eingearbeitet. Jede Form 10 wird von einem Kern 11 durchdrungen,um die Bohrungen 12 der Wälzkörper 6 bilden zu können. An die Formen 10 schließen sich Formabschnitte 13 zur Bildung der Zapfen 4 an. Jedem Wälzkörper 6 ist ein Zapfen 4 zugeordnet, wobei Wälzkörper 6 und Zapfen 4 jeweils auf einer gemeinsamen Achse angeordnet sind. Die Formabschnitte 13 werden teilweise durch den Formblock 8, durch die Kerne 11, durch bewegliche Schieber 14 und durch im Formblock 8 befindliche Ausstoßer 15 gebildet, wobei diese Teile so plaziert sind, daß Verbindungen zwischen Wälzkörper 6 und Zapfen 4 in 1orm vor verhältnismäßig dünnen Ringabschnitten 16 hergestellt sind. Die irormabsehnitte 13 teilweise schneidend, schließt sich eine Ringform 17 zur Bildung des Ringkörpers 3 an. Die Ringform 17 wird durch die Schieber 14, den Formblock 8 und die Ausstoßer 15 begrenzt. Am Rand der Stirnfläche 18 wenigstens zweier Ausstoßer 15 befinden sich Angüsse 19, durch welche die Spritzmasse in die einzelnen Formen 10, 13 und 17 geleitet wird, sodaß ein einziges Teil, bestehend aus Wälzkörperführung 2 und Wälzkörpern 6 entsteht, da ja die Formen 10, 13 und 17 miteinander verbunden sind. Die Formen 10, 13 und 17 können über mehrere Forllmester im Spritzgußwerkzeug 7 verteilt sein, sodaß mit einem Spritzvorgang mehrere Wälzkörperhalter 1 gleichzeitig hergestellt werden können.The injection molding tool 7 consists of a rigid mold block 8, the also includes the sprues 19, as well as from a movable mold block 9. In the mold block 9 molds 10 for forming the rolling elements 6 are incorporated. Each Form 10 is made from a core 11 penetrated in order to be able to form the bores 12 of the rolling elements 6. Mold sections 13 adjoin the molds 10 to form the pins 4. Each Rolling body 6 is assigned a pin 4, wherein Rolling elements 6 and Pin 4 are each arranged on a common axis. The mold sections 13 are partially through the mold block 8, through the cores 11, through movable Slide 14 and formed by the ejector 15 located in the mold block 8, these Parts are placed so that connections between rolling elements 6 and pin 4 in 1orm are made in front of relatively thin ring sections 16. The irormabsehnitte 13 partially intersecting, an annular shape 17 closes to form the annular body 3 at. The ring mold 17 is formed by the slide 14, the mold block 8 and the ejector 15 limited. At least two ejectors 15 are located on the edge of the end face 18 sprues 19, through which the injection molding compound in the individual molds 10, 13 and 17 is passed, so that a single part, consisting of rolling element guide 2 and Rolling bodies 6 is created because the forms 10, 13 and 17 are connected to one another. The molds 10, 13 and 17 can be placed in the injection molding tool 7 over a number of molding machines be distributed, so that several rolling element holders 1 at the same time with one injection process can be produced.
Fig. 3 zeigt das Spritzgußwerkzeug 7, wobei die Schieber 14 angehoben sind und der Formblock 9 vom Formblock 8 soweit wegbewegt ist und wobei auch die Ausstoßer 15 um die gleiche Wegstrecke in Richtung Formblock 9 mitbewegt werden und dabei die Angüsse 19 abtrennen, sodaß freie Räume 20 ent stehen, die so beillessell sind, daß gemäß Fig. 4 die auf den Kerne) 11 bei j.ti(i Lichei# Stößel 21 dtlrch anschließendes axiales Bewegen in Richtung der Zapfen 4 die Wälzkörper 6 auf die Zapfen 4 drücken können. Dabei entstehen durch die Schubkraft im Bereich der dünnen Ringabschnitte 16 Scherkräfte, die das Abreißen der Wälzkörper 6 von den Zapfen 4 bewirken. Die Wälzkörper 6 werden durch Ausnützen der dem Werkstoff Polyamid eigenen Elastizität über je einen am freien Zapfenende befindlichen Bund 5 auf den Zapfen 4 soweit in Richtung Ringkörper 3 gedrückt, bis die seitliche Begrenzung der Wälzkörper 6 durch den Ringkörper 3 einerseits und durch je einen Bund 5 andererseits erfolgt. Dadurch, daß der Innendurchmesser der Wälzkörper 6 geringfügig kleiner ausgebildet ist, als der Durchmesser der Bünde 5, sind somit die Wälzkörper 6 auf den Zapfen unverlierbar gelagert.Fig. 3 shows the injection molding tool 7 with the slide 14 raised are and the mold block 9 is moved away from the mold block 8 and with the Ejector 15 are moved along the same distance in the direction of the mold block 9 and at the same time cut off the sprues 19 so that free spaces 20 are created that are so beillessell are that, according to FIG. 4, the on the cores) 11 at j.ti (i Lichei # ram 21 dtlrch subsequent axial Move the rolling elements in the direction of the pin 4 6 can press on the pin 4. This is caused by the thrust in the area of the thin ring sections 16 shear forces that cause the tearing off of the rolling elements 6 from cause the pin 4. The rolling elements 6 are made by utilizing the material Polyamide has its own elasticity via a collar located at the free end of the peg 5 pressed on the pin 4 in the direction of the ring body 3 until the lateral limit the rolling element 6 by the ring body 3 on the one hand and by a collar 5 on the other hand he follows. Because the inner diameter of the rolling elements 6 is slightly smaller is formed than the diameter of the collars 5, the rolling elements 6 are thus on the pin stored captive.
Nach Beendigung dieses Montagevorganges, der also durch Bewegen verschiedener Teile des Spritzgußwerkzeuges 7 erfolgt, wird durch weiteres Wegbewegen des Formblockes 9 vom Formblock 8 und durch nachfolgendes kurzes Bewegen der Ausstoßer 15 in die gleiche Richtung, der Wälzkörperhalter 1 vom Spritzgußwerkzeug 7 abgestoßen. Der Wälzkörperhalter 1 steht somit gebrauchsfertig zur Verfügung. Durch Schließen des Spritzgußwerkzeuges 7 werden dann erneut die Voraussetzungen zum Herstellen eines neuen Wälzkörperhalters 1 geschaffen.After completion of this assembly process, that is, by moving different Parts of the injection molding tool 7 is made by further moving the mold block 9 from the mold block 8 and then briefly moving the ejector 15 into the in the same direction, the rolling element holder 1 repelled from the injection molding tool 7. Of the Rolling element holder 1 is thus available ready for use. By closing the Injection molding tool 7 are then again the prerequisites for producing a new rolling element holder 1 created.
Gemäß einer Variante zum Ausführungsbeispiel ist es denkbar, beim Öffnungsvorgang des Spritzwerkzeuges 7, zum Zwecke einer etwas einfacheren Bauweise des Spritzgußwerkzeuges, die Walzksirper 6 nicht auf die Zapfen lt ZU drücken, sondern sie im ursprünglichen gespritzten Zustand, über die Ringab- SChllitte l(> mit den Zapfen 4 verl)un(lerl zu Lassen und #:i.e erst beim Einsetzen eines Wälzkörperhalters 1 in ein Had 23, durch Einwirkung manuell oder maschinell erzeugter axialer Schubkräfte auf die Zapfen 4 zu drücken, da der Wälzkörperhalter 1 ohnehin in axialer Richtung in die Lagerbohrung 24 eines Rades 23 gedrückt oder gepreßt werden muß.According to a variant of the exemplary embodiment, it is conceivable when Opening process of the injection molding tool 7, for the purpose of a somewhat simpler construction of the injection molding tool, the Walzksirper 6 do not press on the pin lt ZU, but it in its original injection-molded state, via the ring Slider l (> leave with the pin 4) un (lerl to let and #: i.e only when inserting one Rolling element holder 1 into a had 23, generated by action manually or by machine to press axial thrust forces on the pin 4, since the rolling element holder 1 anyway pressed or pressed in the axial direction into the bearing bore 24 of a wheel 23 must become.
Eine weitere Variante zum Ausführungsbeispiel schlägt vor, am Ringkörper 3 an der den Zapfen 4 abgewandten Seite, in achsparalleler Weise angeordnete Bohrungen und Zapfen so vorzusehen, daß zwei Wälzkörperhalter 1 in über die Bohrungen und Zapfen korrespondierender Weise zu einem einzigen Bauteil, schnappschlüssig zusammengesteckt werden können.Another variant of the embodiment suggests on the ring body 3 on the side facing away from the pin 4, bores arranged in an axially parallel manner and pin to be provided so that two rolling element holder 1 in over the bores and Pin in a corresponding manner to form a single component, snap-fitted together can be.
Einen Anwendungsfall für zwei erfindungsgemäße Wälzkörperhalter 1 zeigt Fig. 5. In die abgesetzte Lagerbohrung 24 eines Rades 23 ist beidseitig je ein Wälzkörperhalter 1 eingefügt, wobei die Wälzkörperbahnen durch zwei Abschnitte der Lagerbohrung 24 und durch die Außenbahnen 26 zweier Nabenstücke 25 gebildet sind. Zwischen der Lagerbohrung 2i und den Außeiibahiien 26 ist dabei soviel Platz geschaffen, daß die Ringkörper 3 der beiden Wälzkörperhalter 1 bequem eingefügt werden können. Nicht zur Erfindung gehörende ringförmige Hinterschneidungen 27 am Rad 23 und an den Nabenstücken 25 bewirken, daß sich die Wälzkörperhalter 1 vom Rad 23 und von den Nabenstücken 25 nicht lösen können.An application for two rolling element holders 1 according to the invention shows Fig. 5. In the offset bearing bore 24 of a wheel 23 is on both sides a rolling element holder 1 inserted, the rolling element paths through two sections the bearing bore 24 and formed by the outer tracks 26 of two hub pieces 25 are. There is so much space between the bearing bore 2i and the outer parts 26 created that the ring body 3 of the two rolling element holder 1 inserted comfortably can be. Not belonging to the invention ring-shaped undercuts 27 on Wheel 23 and on the hub pieces 25 cause the rolling element holder 1 from Wheel 23 and from the hub pieces 25 can not solve.
