摘要： A secondary hammer support structure in a rotary impact tool is structured such that a plurality of steel balls are disposed between a secondary hammer and a retaining member. The plurality of steel balls are arranged between the first retaining groove of the secondary hammer and the second retaining groove of the retaining member. The retaining member is formed as a member separate from the spindle and has a retaining surface for retaining steel balls and a mounting surface mounted to the spindle so as not be rotatable. The mounting surface of the retaining member is mounted to a front member of a carrier.

摘要： A rotary tool includes a driving power source, a spindle formed in a columnar shape extending to a first side of an axial direction, a main hammer including a hammer pawl, an anvil including an anvil pawl engageable with the hammer pawl, a cylindrical secondary hammer disposed so as to cover an outer circumference of the main hammer, a round-columnar pin having an end portion on a second side of the axial direction positioned between the main hammer and the secondary hammer, an impacting mechanism disposed on the spindle so as to support the main hammer, and a casing. At least one end portion of the pin in the axial direction is supported in a radial direction of the pin by at least one of the spindle or the casing in such a manner that a rotation axis of the secondary hammer coincides with a rotation axis of the spindle.

摘要： A torsion output tool has a housing, a motor and a transmission assembly. The transmission assembly includes a first planetary gear train. The first planetary gear train has a first planetary gear carrier, a first level planetary gear, a first inner ring gear disposed outside the first level planetary gear and meshing therewith, and a first central wheel sliding in a direction of a first axis to a first position and a second position. The transmission assembly further has a locking member. The locking member slides synchronously with the first central wheel and only locks the relative circumferential positions of the output shaft and the first planetary gear carrier when the first central wheel is at the first position and only constitutes circumferential engagement with the first planetary gear carrier when the first central wheel is at the second position to achieve a drilling mode and an impact mode of operation for the tool.

摘要： Illustrative embodiments of impact tools are disclosed. In at least one illustrative embodiment, an impact tool may comprise an impact mechanism including a hammer and an anvil. The hammer may be configured to rotate and to move between a disengaged position in which the hammer does not impact the anvil when rotating and an engaged position in which the hammer impacts the anvil when rotating, and the anvil may be configured to rotate when impacted by the hammer. The impact tool may further comprise an electronic controller configured to cause the hammer to (i) rotate in the disengaged position until reaching a threshold rotational speed and (ii) move from the disengaged position to the engaged position in response to the hammer achieving the threshold rotational speed.

摘要： An anvil is disclosed having wings with additional surface area compared to prior art impact wrench anvils. The wings engage respective hammers in a radial direction, and overlap with one another in an axial direction across the interface between the two hammers. The hammers can each include a recess so that one wing does not engage the hammer associated with the other wing. In an embodiment, the surface of the wing can be angled to increase the amount of material extending over the hammer interface.

摘要： A drill includes a housing and a motor having a drive spindle. An output spindle is capable of being rotationally driven by the drive spindle via a torque clutch. The drill further includes a tangential impact mechanism for superimposing tangential impacts onto the output spindle when activated. The tangential impact mechanism includes a sleeve rotatably mounted on the output spindle, and an anvil rotatably mounted onto the output spindle. The sleeve is rotationally driven by the drive spindle via a gear system at a first rotational rate when the torque clutch is not slipping and at a second rotational rate when the torque clutch is slipping.

摘要： An impact tool includes 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, and 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 includes an anvil rotatably supported by the housing and coupled to the drive shaft, and a hammer coupled to the motor to receive torque from the motor and impart the striking rotational force to the anvil. The impact tool also includes a ratcheting mechanism operable to prevent rotation of the anvil and the drive shaft in a selected direction relative to the housing.
