ABSTRACT:
An adjustable locked center and dynamic tensioner include both a method for setting tension in a belt or chain drive system and apparatus for setting the friction torque so as to match the system setting torque. The method includes forcing the tensioner against a stable mounting surface with sufficient spring load that a target friction torque will be required to rotate the tensioner. The tensioner arm is then rotated into the belt or chain until, when the setting torque is removed, the belt or chain will counter rotate the tensioner arm and the target friction torque in the tensioner will cause the target setting tension to remain in the system. The apparatus includes a tensioner arm pivotally mounted on a fixed surface with a spring engaging the arm and being clamped against the fixed surface. Modifications include introducing a compliant coupler such as an elastomeric busing or spring between the stable mounting surface and the tensioner arm.
