Abstract
(DE)
Die vorliegende Erfindung betrifft eine Anordnung zur Messung einer Kraft und/oder eines Momentes an einem Maschinenelement (01). Die Anordnung umfasst eine auf dem Maschinenelement (01) angeordnete Hülse (03), welche einen Magnetisierungsbereich (08) für eine Magnetisierung aufweist. Die Anordnung umfasst weiterhin mindestens einen Magnetfeldsensor, welcher gegenüber der Hülse (03) angeordnet ist. Erfindungsgemäß ist die Hülse (03) in zwei axial beabstandeten Befestigungsbereichen (04) an dem Maschinenelement (01) befestigt. Axial zwischen den Befestigungsbereichen (04) ist ein Zwischenbereich (07) ausgebildet, in welchem die Hülse (03) drehbar auf dem Maschinenelement (01) angeordnet ist.
(EN)
The invention relates to an arrangement for measuring a force or moment on a machine element (01). The arrangement comprises a sleeve (03) arranged on the machine element (01), said sleeve having a magnetization region (08) for magnetization. The arrangement also comprises at least one magnetic field sensor arranged opposite the sleeve (03). According to the invention, the sleeve (03) is secured in two axially spaced apart securing regions (04) on the machine element (01). An intermediate region (07) is formed axially between the securing regions (04) in which the sleeve (03) is rotatably mounted on the machine element (01).

La présente invention concerne un ensemble de mesure d’une force et/ou d’un couple au niveau d’un élément de machine (01). L’ensemble comprend un manchon (03) qui est disposé sur l’élément de machine (01) et qui comporte une région de magnétisation (08) destinée à la magnétisation. L’ensemble comprend en outre au moins un capteur de champ magnétique qui est disposé en face du manchon (03). Selon l’invention, le manchon (03) est fixé à l’élément de machine (01) dans deux régions de fixation (04) espacées axialement. Une région intermédiaire (07), dans laquelle le manchon (03) est monté à rotation sur l’élément de machine (01), est formée axialement entre les régions de fixation (04).
