A control tensioner device for adjusting and maintaining the tension in a flexible linkage in an engine includes a retainer having a central passageway extending therethrough. At least a portion of the central passageway contains a first set of threads. The control tensioner device further includes an adjustment element having a second set of threads. The adjustment element is sized to be threadably received within the central passageway. The adjustment element is adapted to apply pressure on the flexible linkage to maintain the tension. The first set of threads and second set of threads are sized to permit minor relative movement between the retainer and the adjustment element. Furthermore, the first set of threads and second set of threads are sized to be borderline self-locking such that the first and second sets of threads engage in response to minor relative movement between the retainer and the adjustment element.
La présente invention concerne un dispositif de commande de tension permettant de régler et de maintenir la tension d'une transmission souple dans un moteur, qui comprend un disque de retenue possédant un passage central placé en travers de ce disque. Au moins une partie de ce passage central contient un premier ensemble de filets. Ce dispositif de commande de tension comprend aussi un élément de réglage possédant un second ensemble de filets. Cet élément de réglage est dimensionné de façon à être vissé dans ce passage central. Cet élément de réglage est adapté de façon à appliquer une pression sur la transmission souple afin de maintenir la tension. Le premier et le second ensemble de filets sont dimensionnés de façon à permettre un mouvement relatif mineur entre le disque de retenue et l'élément de réglage. Ces premier et second ensembles de filets sont en outre dimensionnés de façon à être autoverrouillant au niveau de la limite de façon que ces premier et second ensembles de filets entrent en contact entre le disque de retenue et l'élément de réglage en réponse au mouvement relatif mineur.
