Abstract
(DE)
Die Erfindung betrifft einen Gurtabstreifer (20, 120). Ein Abstreifelement (22, 24, 124) zur Anlage an einen Gurt (12) ist schwenkbar angeordnet gegenüber einer Schwenkachse (30, 130), wobei ein Federelement (42) ein Drehmoment auf das Abstreifelement (22, 24, 124) bewirkt. Ein Sensor (44) zur Ermittlung eines Schwenkwinkels a des Abstreifelements (22, 24, 124) ist ein berührungsloser Sensor mit einem Indexteil (46) und einem Erfassungsteil (48) zur Erfassung der Stellung des Indexteils (46). Der Indexteil (46) ist an einem mit dem Abstreifelement (22, 24, 124) gekoppelten beweglichen Element (38,136) im Abstand von der Schwenkachse (30,130) angeordnet.
(EN)
The invention relates to a belt scraper (20, 120). A scraper element (22, 24, 124) for placing against a belt (12) is pivotably positioned relative to a pivot axis (30, 130), wherein a spring element (42) effects a torque on the scraper element (22, 24, 124). A sensor (44) for determining a pivot angle a of the scraper element (22, 24, 124) is a non-contact sensor having an indicator part (46) and a detection part (48) for detecting the position of the indicator part (46). The indicator part (46) is mounted at a distance from the pivot axis (30, 130) on a movable element (38, 136) which is coupled to the scraper element (22, 24, 124).
(FR)
L'invention concerne un racleur de courroie (20, 120). Un élément de raclage (22, 24, 124) destiné à venir en appui contre une courroie (12) est disposé de manière pivotante par rapport à un axe de pivotement (30, 130). Un élément ressort (42) provoque un couple sur l'élément de raclage (22, 24, 124). Un capteur (44) servant à déterminer un angle de pivotement a de l'élément de raclage (22, 24, 124) est un capteur sans contact doté d'une partie de repérage (46) et d'une partie de détection (48) servant à détecter la position de la partie de repérage (46). La partie de repérage (46) est disposée sur un élément (38, 136) mobile accouplé à l'élément de raclage (22, 24, 124) à distance de l'axe de pivotement (30, 130).
