  • Patent number: 5370586
    Abstract: There is provided a belt tensioning apparatus for maintaining the tension in the belt of a serpentine belt drive system. The belt tensioning apparatus utilizes a double wrap spiral spring which will approximately double the amount of travel of the tensioning apparatus for a given outside diameter. This significant increase in travel allows the tensioning device to be preset at a variety of initial loads to enable the same tensioner to be used over a broad range of applications.

The mounting system comprises a single piece sleeve which has an elongated slot for contacting the spiral spring on opposite sides and inducing the torsional load.
