摘要： A rotary tool, such as an impact wrench, operable in a forward mode and a reverse mode. The rotary tool includes a housing having a forward end and supporting a motor. The motor has a motor shaft extending axially through the housing and defining an axis. The rotary tool also include a frame supported in the housing and being rotatable relative to the housing about the axis, an output shaft supported in the forward end of the housing and rotatable about the axis, and a hammer pivotably coupled to the frame and defining a central aperture. The hammer has a first jaw and a second jaw extending into the central aperture. The first jaw and the second jaw are non-symmetrical.

摘要： A rotary tool, such as an impact wrench, includes a housing having a forward end and supporting a motor. The motor has a motor shaft extending axially through the housing and defining an axis. The rotary tool further includes a frame coupled to the motor shaft and rotatable relative to the housing about the axis in response to rotation of the motor shaft. The frame defines an interior space. The rotary tool also includes a piston supported by the frame and moveable axially in the interior space and an output shaft supported in the forward end of the housing and rotatable about the axis. The output shaft has a plurality of cams. The piston is engageable with the plurality of cams to intermittently hammer the output shaft.

摘要： A method for improving the accuracy and repeatability of torque applied by discrete energy tools subjected to a wide variety of joint conditions. The method includes relating air pressure to output torque and compensating for temperature and aging variations. Additionally, the method may include a process for detecting previously tightened fasteners.
