  • Belt tensioner combination and a method of installing a tensioner on a belt
    Patent number: 6605013
    Abstract: A combination comprises a belt trained about a plurality of pulleys and a tensioner assembly including a rotary member rotatively engaged by one side of the belt at an operative position. The rotary member is rotatably mounted on an arm pivoted about a fixed pivotal axis and has a rotational axis parallel with the fixed pivotal axis. The vector force applied by the belt to the periphery of the rotary member at the bisector of the belt wrap angle extends through the rotational axis and is related by at least a small angle to a line passing through the rotational and pivotal axis. The vector force acts in a direction to bias the arm to pivot about the pivotal axis in a direction to move the rotary member into the operative position. The rotary member is initially installed into the operative position by moving the arm in the direction from an installation position.
