Abstract:
A tensioner for an endless power transmission belt, the belt being driven about a sheave, the tensioner comprising:a base; a resilient device; first and second arms pivotally coupled for movement in an open and a closed direction; first and second pulleys rotatably coupled to the first and second arms; the resilient device biasing the arms in the closed direction in which the first and second pulleys apply tension to the belt; first and second stops positioned outside the arms on the base to limit the movement of the arms in the open direction in response to an increase in tension in the belt; a securing device; apertures in the first and second arm for receiving the securing device; first and second removable linkages; a section of the first and second arms receiving a first end of the linkages; and a section of the first and second stops receiving a second end of the linkages; wherein when the securing device is removed from the apertures, the resilient device positions the first and second arms in a desired position, sets a static tension in the belt, and the linkages position the first and second stops in a desired position at which the stops are secured to the base.
