    Patent number: 8702543
    Abstract: A tensioner for tensioning a belt that includes a support housing, an arm pivotably attached to the support housing, a spring operatively connected to the support housing and the arm, and a deflectable armplate seated on the arm and deflected into engagement with the support housing to provide an axial force that clamps the arm and the support housing together without axially compressing the spring. The spring biases the arm to pivot relative to the support housing.

  • Belt tensioner
    Patent number: 7887445
    Abstract: A tensioner for tensioning a belt includes a support housing that defines, at least in part, a spring cavity and an arm pivotably attached to the support housing. A spring is disposed in the spring cavity and is operatively connected to the arm and support housing to bias the arm to pivot relative to the support housing. The spring is a round wire coil spring having an unloaded axial height and wherein the spring cavity has a height greater than the unloaded axial height of the spring.
