Title
(EN) ROD REDUCER
(FR) RÉDUCTEUR DE TIGE
Abstract
(EN)
A rod reducer designed to deliver a set screw by way of a decoupled ram and driver shaft. The driver shaft secures and delivers the set screw while the ram applies the load to the rod for reduction. By separating the ram and driver, the rod is reduced down below the start of the female threads, allowing for the set screw to be started by the driver, avoiding binding and additional steps.
(FR)
La présente invention concerne un réducteur de tige qui est conçu pour délivrer une vis de réglage au moyen d’un vérin découplé et d’un arbre d’entraînement. L’arbre d’entraînement fixe et délivre la vis de réglage tandis que le vérin applique la charge à la tige pour réduction. En séparant le vérin et le dispositif d’entraînement, la tige est réduite au-dessous du début des filetages femelles, ce qui permet à la vis de réglage d’être démarrée par le dispositif d’entraînement, de façon à éviter la liaison et des étapes supplémentaires.
