A tensioner in accordance with the present invention employs a spindle and a tensioner arm which are preferably manufactured by a suitable manufacturing process, such as die casting, negating a requirement for machining operations. The biasing spring of the tensioner is wound with wire having a non-circular cross section to increase the spring force of the spring compared to a similar spring wound with wire of circular cross section and, as the tensioner arm is moved away from the flexible drive, the diameter of the biasing spring expands and the coils press a dampening shoe into contact with a wall of the tensioner arm producing a dampening force. The tensioner is simple to assemble and requires a relatively small package volume for the biasing force it can produce.

Le tensionneur conforme à la présente invention utilise un axe et un bras tendeur qui sont fabriqués de préférence par un processus de fabrication approprié, tel que la coulée sous pression, ce qui évite le recours à des opérations d'usinage. Le ressort de rappel du tensionneur est bobiné avec du fil ayant une section transversale non circulaire pour augmenter la force de rappel du ressort par comparaison avec un ressort semblable bobiné avec du fil de section transversale circulaire et, lorsqu'on éloigne le bras tendeur de la transmission par élément flexible, le diamètre du ressort de rappel se dilate et ses spires pressent un patin amortisseur qui heurte alors une paroi du bras tendeur, ce qui produit une force d'amortissement. Le tensionneur est simple à assembler et demande un encombrement relativement faible compte tenu de la force de rappel qu'il peut produire.
