Abstract
The invention provides, in another aspect, an impact tool comprising a housing, a motor having an output shaft defining a first axis, a drive shaft rotatably supported by the housing about a second axis oriented substantially normal to the first axis, a gear coupled for co-rotation with the drive shaft, an impact mechanism coupled between the motor and the drive shaft and operable to impart a striking rotational force to the drive shaft, the impact mechanism including, an anvil rotatably supported by the housing and coupled to the drive shaft, the anvil including a pinion engaged with the drive shaft gear, a hammer coupled to the motor to receive torque from the motor and impart the striking rotational force to the anvil, and a spring washer exerting a preload force on the pinion to maintain the pinion meshed with the drive shaft gear.
