摘要： A tensioner for generating tension in a power-transmitting belt (12, 12A, 112, 112A) is provided. The tensioner includes a base (22, 22A, 122, 122A), which may be secured to an engine (10, 10A, 110, 11 OA), and an arm (24, 24A, 124, 125, 124A, 125A) that is movably attached to the base. A pulley (26, 26A, 126, 127, 126A, 127A) is rotatably attached to the arm for engaging the belt. A spring (28, 28A, 128, 128A) is operatively connected to the arm (24, 24A, 124, 125, 124A, 125A) and the base (22, 22A, 122, 122A) for urging the arm to move relative to the base in a first direction. When the arm is moved in the first direction, the pulley (26, 26A, 126, 127, 126A, 127A) is moved into engagement with the belt (12, 12A, 112, 112A) with a force to tension the belt. The tensioner (114, 14A, 114, 114A) further includes a stop (30, 30A, 130, 131, 130A, 131A) that is adjustably positioned on the base (22, 22A, 122, 122A) to limit the movement of the arm (24, 24A, 124, 125, 124A, 125) in a second direction. The position of the stop (30, 30A, 130, 131, 130A, 131A) on the base may be automatically adjusted by the spring (28, 28A, 128, 128A) during installation of the tensioner.

摘要： A tensioner (14, 114) for an endless power transmission belt, the belt (12) being driven about a sheave. The tensioner may comprise a base (22, 122), a resilient device (46, 146), and first and second arms (24, 26; 124, 126) pivotally coupled for movement in an opened and a closed direction. The tensioner (14, 114) may also comprise first and second pulleys (25, 27; 125, 127) rotably coupled to the and second arms (24, 26; 124, 126), the resilient device (46, 146) biasing the arms in the closed direction in which the first and second pulleys (25, 27; 125, 127) apply tension to the belt (12). The tensioner (14, 114) may also comprise first and second stops (28, 30; 128, 130) positioned outside the arms on the base (22, 122) to limit the movement of the arms in the open direction in response to an increase in tension in the belt.
