Title (DE) SPANNEINRICHTUNG FÜR ZUGMITTEL MIT KONUS-GLEITLAGER
(EN) TENSIONING DEVICE FOR TRACTION MEANS WITH CONE FRICTION BEARING
(FR) DISPOSITIF DE SERRAGE DOTE D'UN PALIER A FRICTION CONIQUE ET DESTINE A DES MOYENS DE TRACTION
Abstract:
(DE) Eine Spanneinrichtung für Zugmittel weist einen Spannarm (1) auf, dessen Spannrolle (2) gegen das Zugmittel angefedert ist. Der Spannarm (1) ist gegenüber einem Gehäuse (4) mittels eines Gleitlagers (3) drehbar gelagert. Die Gleitlagerflächen (7, 12) sind als zueinander parallel und zur Spannarmachse (5) konzentrisch angeordnete Kegelflächen ausgebildet. Eine entlang der Spannarmachse (5) gewundene, einerseits an einer spannarmfesten Stütze (15) und andererseits an einer ortsfesten Stütze (16) abgestützten Schraubendrehfeder (14) übt eine axiale Kraft (FD) aus, die als zu den Gleitlagerflächen (7, 12) senkrecht angeordnete Reaktionskraft (FR) in das Gleitlager (2) eingeleitet wird.
(EN) A tensioning device for traction means has a tension arm (1) whose tension roller (2) is held by a spring force against the traction means. The tension arm (1) is mounted on a friction bearing (3) opposite a housing (4) and can rotate. The friction bearing surfaces (7, 12) are conical surfaces configured parallel to one another and concentric with the tension arm axis (5). A helical spring (14) wound along the tension arm axis (5) is fixed on one side to a tension arm-fixed support (15) and on the other to a stationary support (16) and exerts an axial force (FD) which is directed into the friction bearing (2) as a reaction force (FR) perpendicular to the friction bearing surfaces (7, 12).
(FR) Un dispositif de serrage pour moyens de traction présente un bras (1) de tension dont le rouleau (2) de tension est maintenu contre le moyen de traction sous l'action d'un ressort. Le bras (1), monté face à un boîtier (4) au moyen d'un palier (3) à friction, est pivotant. Les surfaces (7, 12) du palier à friction sont conçues sous forme de surfaces parallèles entre elles et concentriques par rapport à l'axe (5) du bras. Un ressort hélicoïdal (14) enroulé autour de l'axe (5) du bras, plaqué d'un côté contre un support (15) fixé à un bras de tension et, de l'autre côté, contre un support (16) fixe, exerce une force (FD) axiale dirigée dans le palier (2) à friction sous la forme d'une force (FR) de réaction perpendiculaire aux surfaces (7, 12) du palier à friction.
