Title
(DE) ROLLE FÜR EINEN RIEMENTRIEB
(EN) ROLLER FOR A BELT DRIVE
(FR) CYLINDRE DESTINE A UN ENTRAINEMENT A COURROIE
Abstract
(DE)
Eine Spann- oder Umlenkrolle (1) für einen Riemenbetrieb besteht aus einer Laufrolle (2) die über ein Wälzlager (3) auf einem Tragelement (4) drehbar mit Hilfe einer Befestigungsschraube (4.2) gelagert ist. Die Laufrolle (2) ist beidseitig abgedichtet, wobei in erfindungsgemäßer Weise zwischen dem Tragelement (4) und der Laufrolle (2) ein fest mit deren Innenring (2.4) verbundenes zweites Dichtelement in Form einer Abdeckkappe (6) angeordnet ist.
(EN)
A tightening roller or a deflection roller (1) for a belt drive consists of a roller (2), which is rotationally mounted, via an antifriction bearing (3), on supporting element (4) with the aid of a fastening screw (4.2). The roller (2) is sealed on both sides, whereby that invention provides that a second sealing element, which is joined in a fixed manner to the inner ring (2.4) of the roller, is placed between the supporting element (4) and the roller (2).
(FR)
L'invention concerne un cylindre de tension ou de déviation (1) destiné à un entraînement à courroie, composé d'un cylindre de roulement (2) logé de façon rotative sur un élément support (4) par l'intermédiaire d'un palier à roulement (3), à l'aide d'une vis de fixation (4.2). Ledit cylindre de roulement (2) est étanchéifié bilatéralement, un deuxième élément d'étanchéité se présentant sous la forme d'un capuchon de couverture (6), relié fixement à la bague intérieure (2.4), étant disposé entre l'élément support (4) et le cylindre de roulement (2).
