Abstract

The lowering transmission includes eccentrics (8) acting on slowly rotating tools for surface abrasion of slotting, particularly of stone or minerals. The eccentrics induce a revs. reducing drive by means of engages inner (2) and outer (1) toothed gear wheels, of which one of the two has devices for damping its vibration.

Description

Es gibt diverse Systeme Abtragwerkzeuge für Gestein, Mineralien und dgl. schlagzuüberlagern - nur schlagend oder angetrieben fräsend schlagend. Beim angetriebenen exzenterschlagüberlagerten fräsenden Abtragen benötigt man ein stark untersetzendes Getriebe - wie z. B. in Fig. 1 in EP 0 592 981 und in Fig. 1 der EP 0 329 915 dargestellt. Es besteht in der Fig. 2 dieser neuen Anmeldung aus einem Außenzahnkranz (15), der in einem stehenden gestellfest gehaltenen Innenzahnkranz (16) abläuft - umgekehrt als alternative Variante. Beispiel: Der Antrieb (12) der Exzenterhülse (13) läuft z. B. mit 3.000 U/min - die Welle (11) mit dem Werkzeug (10) nur ca. 200 U/min.There are various systems for stripping tools for rock, minerals and the like - only to be struck or driven to be driven. With driven eccentric impact superimposed milling removal, you need a strongly reducing gear - such as. B. in Fig. 1 in EP 0 592 981 and in Fig. 1 of EP 0 329 915. In Fig. 2 of this new application, it consists of an external ring gear ( 15 ) which runs in a stationary internal ring gear ( 16 ) held fixed to the frame - vice versa as an alternative variant. Example: The drive ( 12 ) of the eccentric sleeve ( 13 ) runs z. B. with 3,000 rpm - the shaft ( 11 ) with the tool ( 10 ) only about 200 rpm.

Es hat sich herausgestellt, daß durch das systembedingte kontinuierliche Beschleunigen und Bremsen so extreme Kräfte auftreten, daß sich die Befestigungen der Zahnräder lösen und die Zahnräder noch dazu vorzeitig verschleißen. Um diesem Problem entgegenzuwirken und es erfolgreich zu eliminieren, wird erfindungsgemäß entweder der gestellfest gehaltene Innen- oder der Außenzahnkranz mit Dämpfungsmitteln versehen, d. h. durch elastische und/oder federnde Elemente an/in einem der Zahnkränze oder durch eine tordierende Welle aus vorzugsweise Federstahl - z. B. im Antriebsstrang.It has been found that due to the systemic continuous acceleration and brakes such that extreme forces occur that the fastenings of the gearwheels come loose and wear the gears prematurely. To this problem to counteract and successfully eliminate it, according to the invention, either the Provide internal or external toothed ring fixed to the frame with damping means, d. H. by elastic and / or resilient elements on / in one of the sprockets or by a twisting shaft preferably made of spring steel - e.g. B. in the drivetrain.

In der Fig. 1, nur einem Ausführungsbeispiel, ist (1) ein gestellfest gehaltenes Zahnrad mit Außenverzahnung. Der Innenzahnkranz (2) ist mit dem Ring (3) fest verbunden. Er ist in der werkzeugtragenden langsam rotierenden Hülse (4) radial drehbar gelagert. (5) ist einer der Mitnehmer, die am rotierenden Werkzeugträger (4) befestigt sind. Die Dämpfung erfolgt hier über die Federn (6). (7) sind Dämpfungsmittel aus elastisch plastischem Material. Mit (8) soll der Exzenter nur angedeutet sein und mit (9) die Hin- und Herbewegungen beim Ineinanderablaufen des Zahnradpaares.In Fig. 1, only one embodiment, ( 1 ) is a fixed gear with external teeth. The internal ring gear ( 2 ) is firmly connected to the ring ( 3 ). It is mounted in the tool-carrying, slowly rotating sleeve ( 4 ) in a radially rotatable manner. ( 5 ) is one of the drivers that are attached to the rotating tool carrier ( 4 ). The damping takes place here via the springs ( 6 ). ( 7 ) are damping means made of an elastic plastic material. With ( 8 ) the eccentric should only be indicated and with ( 9 ) the back and forth movements when the pair of gears run into one another.

In der Fig. 2 ist (10) ein aktiviert flächig oder schlitzendes Werkzeug, das über die Welle (11) vergleichsweise langsam drehend/schlagend angetrieben arbeitet. Diese ist in der über (12) schnelldrehend angetriebenen Hülse (13) drehend gelagert. Hierbei übernimmt die Welle (10) die Dämpfung über ihre Torsion, vorzugsweise über eine die Torsion erhöhende Einschnürung (14). Mit (15) ist das mit der Antriebswelle fest verbundene Zahnrad mit Außenverzahnung bezeichnet, das in dem gestellfest gehaltenen Innenzahnkranz (16) extrem drehzahlreduzierend abläuft.In Fig. 2 ( 10 ) is an activated flat or slitting tool that works comparatively slowly rotating / striking driven via the shaft ( 11 ). This is rotatably supported in the sleeve ( 13 ), which is driven by ( 12 ) at high speed. Here, the shaft ( 10 ) takes over the damping via its torsion, preferably via a constriction ( 14 ) that increases the torsion. ( 15 ) denotes the gear wheel with external toothing which is fixedly connected to the drive shaft and which runs in the internal gear rim ( 16 ) which is fixed to the frame, reducing the speed extremely.
