Abstract
Antriebseinheit mit einem Gehäuse (1) und einer Welle (4), wobei das Gehäuse (1) eine Lagerung (3) aufweist, in der die Welle (4) drehbar gelagert ist, wobei die Welle (4) mittels eines Spannelements (6) mit der Lagerung (3) axial verspannt ist, wobei auf dem Spannelement (6) eine Maßverkörperung (8) angeordnet ist, wobei am Gehäuse (1) ein Abtastelement (9) angeordnet ist, mittels dessen die Maßverkörperung (8) abtastbar ist.Drive unit with a housing (1) and a shaft (4), the housing (1) having a bearing (3) in which the shaft (4) is rotatably mounted, the shaft (4) by means of a tensioning element (6) is axially clamped to the bearing (3), a measuring scale (8) being arranged on the clamping element (6), a scanning element (9) being arranged on the housing (1), by means of which the measuring scale (8) can be scanned.
Description
Die vorliegende Erfindung betrifft eine Antriebseinheit mit einem Gehäuse und einer Welle, wobei das Gehäuse eine Lagerung aufweist, in der die Welle drehbar gelagert ist, wobei die Welle mittels eines Spannelements mit der Lagerung axial verspannt ist, wobei am Gehäuse ein Abtastelement angeordnet ist, mittels dessen eine mit der Welle drehfest verbundene Maßverkörperung abtastbar ist.The present invention relates to a drive unit with a housing and a shaft, wherein the housing has a bearing in which the shaft is rotatably supported, wherein axially braced the shaft with the bearing by means of a clamping element is, on the housing a scanning element is arranged, by means of which one with the shaft non-rotatably connected measuring standard is palpable.
Derartige Antriebseinheiten sind allgemein bekannt. Bei ihnen werden mittels des Abtastelements und der Maßverkörperung die Drehstellung der Welle und/oder die Drehzahl der Welle ermittelt. Die Maßverkörperung ist üblicherweise auf einem Messrad angeordnet, das auf die Welle aufgeschoben und mittels des Spannelements drehfest und axial unverschieblich gehalten ist.Such drive units are well known. They are by means of the scanning element and the material measure the rotational position of the shaft and / or the speed of the shaft is determined. The Measuring standard is common arranged on a measuring wheel that slid onto the shaft and by means of the clamping element rotatably and axially immovable is.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine Antriebseinheit zu schaffen, die konstruktiv einfacher ausgebildet ist als Antriebseinheiten des Standes der Technik.The object of the present invention is to create a drive unit that is constructive is simpler than drive units of the prior art Technology.
Die Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Die Vorteile der Erfindung liegen darin, dass die Maßverkörperung auf dem Spannelement selbst angeordnet ist. Denn dadurch übernimmt das Spannelement zusätzlich zu seiner eigentlichen Funktion als 5pannelement auch die Funktion eines Trägers für die Maßverkörperung.The task is characterized by the characteristics of claim 1 solved. The advantages of the invention are that the material measure is arranged on the clamping element itself. Because that takes over Additional clamping element to its actual function as a clamping element, also the function of a carrier for the Measuring scale.
Das Spannelement kann alternativ beispielsweise als Druckring oder als Wellenmutter ausgebildet sein.The clamping element can alternatively for example, be designed as a pressure ring or as a shaft nut.
Die Maßverkörperung kann als optische Maßverkörperung ausgebildet sein. Vorzugsweise aber ist sie als magnetische Maßverkörperung ausgebildet.The material measure can be an optical material measure be trained. But preferably it is a magnetic measuring standard educated.
Weitere Vorteile und Einzelheiten ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels. Dabei zeigen in PrinzipdarstellungOther advantages and details result from the following description of an exemplary embodiment. Show in principle
