Abstract
Die Erfindung betrifft einen Stellantrieb, umfassend ein Gehäuse (1), einen elektrischen Antriebsmotor (2) und ein in dem Gehäuse angeordnetes Getriebe (3). Damit die Standfestigkeit des Stellantriebs auch unter hohen Belastungen verbessert ist, wird vorgeschlagen, dass ein Teil von Rädern (6, 7, 9, 10) des Getriebes (3) aus Kunststoff und mindestens eines der Räder (6, 7, 9, 10) einer zweiten Getriebestufe (8) aus Metall gefertigt ist.The invention relates to an actuator, comprising a housing (1), an electric drive motor (2) and a transmission (3) arranged in the housing. Thus, the stability of the actuator is improved even under high loads, it is proposed that a part of wheels (6, 7, 9, 10) of the transmission (3) made of plastic and at least one of the wheels (6, 7, 9, 10) a second gear stage (8) is made of metal.
Description
Die Erfindung betrifft einen Stellantrieb, umfassend ein Gehäuse, einen elektrischen Antriebsmotor und ein in dem Gehäuse angeordnetes Getriebe. The invention relates to an actuator, comprising a housing, an electric drive motor and a transmission arranged in the housing.
Solche Stellantriebe, auch als Aktuatoren bezeichnet, sind an sich bekannt und werden z.B. in Kraftfahrzeugen vielseitig eingesetzt, z.B. um Regelorgane zu verstellen. Besonders im Motorraum sind hierbei häufig Einbausituationen zu beachten, bei denen nur sehr wenig Bauraum für den Stellantrieb zur Verfügung steht und der Stellantrieb daher sehr kompakt ausgeführt sein muss. Weiterhin sollen die Stellantriebe ein möglichst geringes Gewicht aufweisen. Hierbei müssen die Anforderungen an Leistung, Robustheit und Zuverlässigkeit erfüllt sein. Dies gilt insbesondere beim Einsatz der Stellantriebe für Turbolader. Such actuators, also referred to as actuators, are known per se and are e.g. versatile in motor vehicles, e.g. to adjust regulatory organs. Especially in the engine compartment here installation situations are often observed in which only very little space for the actuator is available and the actuator must therefore be made very compact. Furthermore, the actuators should have the lowest possible weight. Here, the requirements for performance, robustness and reliability must be met. This is especially true when using the actuators for turbocharger.

Als Rad gilt im Sinn der Erfindung jede Art von Zahnrad; insbesondere sind als Räder Stirnräder, Schnecken und Schneckenräder definiert. As a wheel in the context of the invention, any type of gear; in particular are defined as wheels spur gears, worms and worm wheels.
Bei stark beanspruchten Stellantrieben, z.B. für Turbolader von Verbrennungsmotoren, hat sich herausgestellt, dass die Standfestigkeit des Getriebes den hohen Ansprüchen nicht genügt. For heavy-duty actuators, e.g. For turbochargers of internal combustion engines, it has been found that the stability of the transmission does not meet the high standards.
Es ist daher die Aufgabe der Erfindung, einen Stellantrieb zu schaffen, dessen Standfestigkeit auch unter hohen Belastungen verbessert ist. It is therefore an object of the invention to provide an actuator whose stability is improved even under high loads.
Die Aufgabe ist durch die Merkmale des Anspruchs 1 gelöst. Ein Teil von Rädern des Getriebes ist aus Kunststoff und mindestens eines der Räder einer zweiten Getriebestufe ist aus Metall gefertigt. Dieses aus Metall gefertigte Rad ist mechanisch höher beanspruchbar und hält daher auch hohen Belastungen besser stand. Ein Verschleiß wird stark vermindert. Daher wird die Dauerfestigkeit des Stellantriebs insgesamt erhöht. Erfindungsgemäß werden nur die Räder aus Metall gefertigt, die besonders beansprucht sind. Hierdurch werden Kosten eingespart und ein Gewicht des Stellantriebs so gering wie möglich gehalten. The object is solved by the features of
Die Unteransprüche betreffen die vorteilhafte Ausgestaltung der Erfindung. In einer Ausgestaltung umfasst das Getriebe ein Schneckengetriebe, und das aus Metall gefertigte Rad ist eine Schnecke. Hier ist die Erfindung besonders vorteilhaft, weil die Schnecke einer Gleitreibung und somit erhöhtem Verschleiß unterliegt. The subclaims relate to the advantageous embodiment of the invention. In one embodiment, the transmission includes a worm gear, and the metal-made wheel is a worm. Here, the invention is particularly advantageous because the screw is subject to sliding friction and thus increased wear.
In einer weiteren Ausgestaltung ist das Metall Messing. Dieses lässt sich bei befriedigenden Materialeigenschaften gut verarbeiten. In a further embodiment, the metal is brass. This can be processed well with satisfactory material properties.
In einer weiteren Ausgestaltung ist auf eine Welle des aus Metall gefertigten Rades ein erstes Stirnrad aus einem reibungsarmen Kunststoff aufgespritzt. Dies gewährleistet einen sicheren Kraftschluss zu einer ersten Getriebestufe und gewährleistet in dieser eine optimale Materialpaarung der Räder. Weiterhin ist die Montage des Getriebes erleichtert. In a further embodiment, a first spur gear of a low-friction plastic is sprayed onto a shaft of the metal-made wheel. This ensures a secure adhesion to a first gear stage and ensures optimal material pairing of the wheels in this. Furthermore, the assembly of the transmission is facilitated.
In einer weiteren Ausgestaltung ist an jedem Ende der Welle eine Lagerhülse aus Kunststoff befestigt. Dies gewährleistet die korrekte axiale und radiale Lagerung der Schnecke. In a further embodiment, a bearing sleeve made of plastic is attached to each end of the shaft. This ensures the correct axial and radial bearing of the screw.
In einer weiteren Ausgestaltung ist der Antriebsmotor ebenfalls in dem Gehäuse gelagert und hierbei durch eine Trennwand von dem Getriebe abgeschottet. Der Stellantrieb ist so zu einer Einheit zusammengefasst, die eine einfache Endmontage erlaubt. In a further embodiment, the drive motor is also mounted in the housing and thereby sealed off from the transmission by a partition wall. The actuator is thus combined to a unit that allows easy final assembly.
Anhand der beigefügten Zeichnung wird die Erfindung nachfolgend näher erläutert. Reference to the accompanying drawings, the invention is explained in more detail below.
