Abstract
Description
Die Erfindung betrifft eine elektrische Stellmotor-Getriebeeinheit nach dem Oberbe griff des Patentanspruchs 1.The invention relates to an electric servomotor gear unit according to the Oberbe handle of claim 1.
Diese Stellmotor-Getriebeeinheit unterliegt bei Einsatz in der Brennkraftmaschine höchsten Qualitätsansprüchen, wobei sie als Massenprodukt unter hohem Wettbe werbsdruck steht, das heißt wirtschaftlich fertigbar sein muß.This servomotor gear unit is subject to use in the internal combustion engine highest quality standards, being a mass product under high competition advertising pressure stands, that means must be economically producible.
Es ist daher Aufgabe der Erfindung, eine gattungsgemäße Stellmotor-Getriebe einheit zu gestalten, die qualitativ hochwertig und wirtschaftlich zu fertigen ist.It is therefore an object of the invention to provide a generic servomotor gear to design a unit that is of high quality and economical to manufacture.
Diese Aufgabe ist durch die im Kennzeichen des Patentanspruchs 1 genannten Merkmale gelöst. Vorteilhafte Weiterbildungen sind mit den Unteransprüchen ange geben.This object is by those mentioned in the characterizing part of claim 1 Features resolved. Advantageous further developments are indicated in the subclaims give.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend beschrieben.An embodiment of the invention is shown in the drawing and will described below.
Die Zeichnung zeigt einen Schnitt durch eine elektrische Stellmotor-Getriebeeinheit 1, insbesondere für Ventil- bzw. Drosselklappenverstellungen bei Brennkraftma schinen, mit der hohe Übersetzungen zwischen einer Stellmotorwelle 2 und einer Getriebeausgangswelle 3 oder -stößelverstellung 4 erreicht werden.The drawing shows a section through an electric servomotor gear unit 1 , in particular for valve and throttle valve adjustments in internal combustion engines, with which high ratios between an actuator shaft 2 and a gear output shaft 3 or tappet adjustment 4 can be achieved.
In der Darstellung ist in Strichpunktlinie eine Ausführung für einen Wellenzapfen 3 und in Vollinie eine Ausführung mit einem Kurbelzapfen für die Stößelverstellung 4 gezeigt. In the illustration, a version for a shaft journal 3 and a version with a crank pin for the tappet adjustment 4 are shown in the chain line.
Erfindungsgemäß ist nun vorgesehen, daß die Stellmotor-Getriebeeinheit 1 aus zwei zusammengesetzten Gehäusen 5 und 6 besteht, die Stellmotorwelle 2 einen Kurbel zapfen 7 aufweist, auf dem ein Doppelzahnrad 8 drehbar gelagert ist, dessen erster äußerster Zahnkranz 9 mit einer koaxial zur Motorwelle 2 angeordneten Gehäuse hohlverzahnung 10 kämmt und dessen zweiter, kleinerer Zahnkranz 11 mit einer Hohlradinnenverzahnung 12 eines drehbar und koaxial zur Motorwelle 2 im Gehäuse 6 gelagerten Hohlrades 13 kämmt, das einen Kurbelzapfen 14 für den Antrieb eines Stellstößels 15 oder eines Hebels oder einen zentrisch zur Hohlradlagerung ange ordneten Wellenzapfen 16 aufweist.According to the invention it is now provided that the servo gear unit 1 consists of two composite housings 5 and 6 , the servomotor shaft 2 has a crank pin 7 on which a double gear 8 is rotatably mounted, the first outermost ring gear 9 arranged with a coaxial to the motor shaft 2 Hollow gear housing meshes 10 and its second, smaller ring gear 11 meshes with a ring gear internal toothing 12 of a rotatable and coaxial to the motor shaft 2 in the housing 6 mounted ring gear 13 , which is a crank pin 14 for driving a plunger 15 or a lever or a centrically arranged for the ring gear bearing Has shaft journal 16 .
Durch diese Anordnung ist eine mit wenigen Bauteilen herstellbare Stellmotor- Getriebeeinheit geschaffen worden, deren Qualität hochwertig und deren Preis ge ring ist.This arrangement makes it possible to produce a servomotor with only a few components. Gear unit has been created, the quality of which is high quality and the price ring is.
Es ist vorteilhaft, wenn die Motorwelle 2 zusätzlich in einem Lager 17 des Hohlrades 13 gelagert ist, wobei der Kurbelzapfen 7 als Exzenterscheibe (nicht extra darge stellt) ausgeführt ist, die drehfest mit der Motorwelle 2 verbunden ist, und daß der Kurbelzapfen 14 des Hohlrades 13 einen Lagerring 18 für die Anlage des Stellstö ßels 15 trägt.It is advantageous if the motor shaft 2 is additionally mounted in a bearing 17 of the ring gear 13 , wherein the crank pin 7 is designed as an eccentric disk (not extra Darge), which is rotatably connected to the motor shaft 2 , and that the crank pin 14 of the ring gear 13 carries a bearing ring 18 for the installation of the adjusting tappet 15 .
Es kann vorteilhaft sein, wenn der Kurbelzapfen 14 des Hohlrades 13 als Kurven scheibe (nicht extra dargestellt) ausgeführt ist, womit ein spezielles Stößelerhe bungsprofil erreichbar ist.It can be advantageous if the crank pin 14 of the ring gear 13 is designed as a cam disc (not shown separately), whereby a special tappet profile can be achieved.
Wie bereits angegeben, kann anstelle des Kurbelzapfens ein koaxial zum Hohlrad angeordneter Wellenzapfen vorgesehen werden für einen untersetzten Drehantrieb.As already stated, instead of the crank pin, a coaxial to the ring gear arranged shaft journals are provided for a step-down rotary drive.
Die drehende Motorwelle 2 läßt den Kurbelzapfen 7 und das auf diesem drehbar gelagerte Doppelzahnrad 8 kreisen. Der erste Zahnkranz 9 des Doppelzahnrades 8 kämmt dabei in den Zähnen der Gehäusehohlverzahnung 10 und dreht sich dabei auf dem Kurbelzapfen 7 z. B. je nach Zähnezahlverhältnis einmal bei drei Wellen drehungen. The rotating motor shaft 2 can rotate the crank pin 7 and the double gear 8 rotatably mounted on this. The first ring gear 9 of the double gear 8 meshes in the teeth of the hollow housing teeth 10 and rotates on the crank pin 7 z. B. depending on the number of teeth ratio once with three shafts.
Je nach Zähnezahlverhältnis zwischen dem zweiten Zahnkranz 11 und der Hohlrad innenverzahnung 12 dreht sich das Hohlrad 13 infolge seiner Ausgleichsdrehung z. B. bei drei Doppelzahnraddrehungen ebenfalls um eine Drehung. Insgesamt läßt sich so ein gewünschtes Gesamtübersetzungsverhältnis erreichen.Depending on the number of teeth ratio between the second ring gear 11 and the ring gear internal teeth 12 , the ring gear 13 rotates due to its counter-rotation z. B. with three double gear rotations also by one rotation. Overall, a desired overall transmission ratio can be achieved in this way.
