Title
(EN) IMPACT TOOL
(FR) OUTIL À PERCUSSION
Abstract
(EN)
An impact tool includes a housing having a handle portion defining a first axis, a motor supported by the housing and defining a motor axis, and a rotary impact mechanism arranged on a second axis that is perpendicular to the first axis. The rotary impact mechanism is configured to convert a continuous rotational input from the motor to consecutive rotational impacts upon a workpiece. The rotary impact mechanism includes a chamber containing a hydraulic fluid, an anvil positioned at least partially within the chamber, and a hammer for imparting the consecutive rotational impacts upon the anvil. The hydraulic fluid is configured to attenuate a noise of the rotary impact mechanism that is created by the hammer impacting the anvil. The impact tool further includes a gear train that receives torque from the motor and includes a rotational input that transfers torque to the rotary impact mechanism.
(FR)
L'invention concerne un outil à percussion comprenant un boîtier ayant une portion de poignée définissant un premier axe, un moteur supporté par le boîtier et définissant un axe de moteur, et un mécanisme de percussion rotatif disposé sur un deuxième axe qui est perpendiculaire au premier axe. Le mécanisme de percussion rotatif est conçu pour convertir une entrée rotative continue du moteur en impacts rotatifs consécutifs sur une pièce ouvrée. Le mécanisme de percussion rotatif comprend une chambre contenant un fluide hydraulique, une enclume positionnée au moins partiellement à l'intérieur de la chambre et un marteau pour communiquer les impacts rotatifs consécutifs sur l'enclume. Le fluide hydraulique est configuré pour atténuer un bruit du mécanisme de percussion rotatif qui est créé par le marteau percutant l'enclume. L'outil à percussion comprend en outre un train d'engrenages qui reçoit un couple provenant du moteur et comprend une entrée rotative qui transfère un couple au mécanisme de percussion rotatif.
