A tensioner for a power transmission belt that is adapted to be operated in an endless path and a method of making the tensioner is provided, the tensioner comprising a support unit for being fixed relative to the belt, a belt engaging unit carried by the support unit and being movable relative thereto, a coiled torsion spring having a first end operatively interconnected to the support unit and a second end operatively interconnected to the belt engaging unit for urging the belt engaging unit relative to the support unit and against the belt with a force to tension the belt, the spring having a certain torque when the belt engaging unit is disposed at a certain position relative to the support unit, the tensioner having changeable structure holding one of the ends in an adjusted position relative to its respective operatively interconnected unit so as to provide for the certain torque of the spring when the belt engaging unit is disposed at the certain position relative to the support unit.
In a tensioner for a power transmission belt that is adapted to be operated in an endless path, said tensioner comprising a support means for be in fixed relative to said belt and having a shaft means, a belt engaging means carried by said support means and having a movable relative thereto, a coiled torsion spring having a first end operatively interconnected to said support means and a second end operatively interconnected to said belt engaging means for urging said belt engaging means relative to said support means and against said belt with a force to tension support means and against said belt with a force to tension said belt, said spring having a certain torque when said belt engaging means is disposed at a certain position relative to said support means, the improvement wherein said tensioner has changeable structure holding said second end of said spring in an adjusted position relative to said belt engaging means so as to provide for said certain torque of said spring when said belt engaging means is disposed at said certain position relative to said support means.
In a method of making a tensioner for a power transmission belt that is adapted to be operated in an endless path, said tensioner comprising a support means for being fixed relative to said belt and having a shaft means, a belt engaging means carried by said support means and having an arbor means rotatably disposed on said shaft means and being movable relative thereto, a coiled torsion spring having a first end operatively interconnected to said support means and a second end operatively interconnected to said belt engaging means for urging said belt engaging means relative to said support means and against said belt with a force to tension said belt, said spring having a certain torque when said belt engaging means is disposed at a certain position relative to said support means, the improvement comprising the step of forming said tensioner to have changeable structure holding said second end of said spring in an adjusted position relative to sad belt engaging means so as to provide for said certain torque of said spring when said belt engaging means is disposed at said certain position relative to said support means.
