Title (EN) IMPROVED HANDHELD POWER TOOL
(FR) OUTIL ÉLECTRIQUE PORTATIF AMÉLIORÉ
Abstract:
(EN) A sprocket arrangement (5) for a handheld power tool such as a saw, comprising a drive unit configured to rotate a drive shaft and cutting tool configured to be driven by the drive shaft (21) via the sprocket arrangement. The sprocket arrangement (5) comprises a gear (1) and at least one flexible element (6a, 6b) arranged such that the drive shaft (21) in the handheld power tool is resiliently connected to the cutting tool in the handheld power tool. A handheld power tool comprising a drive unit, a drive shaft, driving means, and a sprocket arrangement is also provided.
(FR) Un agencement de pignon (5) pour un outil électrique portatif tel qu'une scie, comprend une unité d'entraînement conçue pour faire tourner un arbre d'entraînement, et un outil de coupe conçu pour être entraîné par l'arbre d'entraînement (21) par l'intermédiaire de l'agencement de pignon. L'agencement de pignon (5) comprend une roue dentée (1) et au moins un élément flexible (6a, 6b), agencé de sorte que l'arbre d'entraînement (21) de l'outil électrique portatif soit relié de manière élastique à l'outil de coupe dans l'outil électrique portatif. L'invention concerne également un outil électrique portatif comprenant une unité d'entraînement, un arbre d'entraînement, un moyen d'entraînement et un agencement de pignon.
