摘要： A crusher belt tensioning apparatus is arranged for being mounting on a crusher having a driven crusher pulley to actuate a crusher, a drive pulley drivable by a power unit, a belt extending between the crusher pulley and the drive pulley to transfer drive from the power unit to the crusher, and a tension drum mounted on a tension arm for applying a tension force to the belt. The tension arm includes a first relatively short arm portion and a second relatively long arm portion connected to the first relatively short arm portion. The tension drum is movable by a hydraulic cylinder, attached to the relatively short arm portion, between a first belt tensioning operating position in which the tension drum applies tension to the belt and a second belt non-tensioning maintenance position in which the belt is removable from the tensioning apparatus.

摘要： A tensioner having a closing-type torsion spring that is employed to bias a pivot arm about a pivot shaft. The tensioner includes a damper, which contacts an inside surface of the torsion spring to dampen torsional vibration transmitted through the torsion spring, and a one-way clutch that is configured to permit unencumbered rotation of the pivot shaft in one rotational direction but to resist rotation of the pivot shaft in an opposite direction.

The pulley is supported by an arm and by a rotary part which has one end of an elastically-deformable element fixed thereto, the element being wound around the part and having its other end fixed to a fixed point. The element is constituted by a length of flat belt comprising a layer of cord embedded in a strip of elastomer material. The invention is particularly applicable to the car industry and to the domestic appliance industry.

摘要： In an aspect, a tensioner for tensioning an endless drive member on an engine, is provided, comprising a base that mounts to the engine, a tensioner arm that is pivotally connected to the base for pivotal movement about a tensioner arm axis, a pulley rotatably mounted to the tensioner arm for rotation about a pulley axis that is spaced from the tensioner arm axis, a tensioner spring and a damping member. The tensioner spring is positioned to urge the tensioner arm into an endless drive member. The spring has a first helical end and a second helical end. The first helical end is positioned to transfer force with a first spring end force transfer surface on the base and the second helical end is positioned to transfer force with a second spring end force transfer surface on the tensioner arm. The damping member is positioned in a surrounding relationship with the tensioner spring. The damping member includes a spring force adjustment member having a first end face and a second end face spaced from the first end face by a selected angular spacing. The damping member includes a first portion that contains the spring force adjustment member and that is generally rigid, and at least one second portion that is adjacent the first member and that is flexibly joined to the first member. The spring force adjustment member is positioned between one of the spring ends and one of the spring end force transfer surfaces on one of the base and the tensioner arm. The damping member is frictionally engaged with the other of the base and the tensioner arm during pivotal movement of the tensioner arm relative to the base.
