Abstract
A motor-driven machine tool (1) for tools which are to be driven rotationally has, configured as a hand-held machine tool, a pistol-shaped basic shape, in which, lying one behind the other in the stock part (2) in the direction of the main axis, a motor (4), a gear mechanism (5) and a tool changing magazine (6) are provided as a structural unit, wherein the tool changing magazine (6) which is designed, in particular, as a drum magazine is mounted on a neck (24) of the gear mechanism housing (22) and is penetrated by the output shaft (23) of the gear mechanism (5).
Claims20
A motor-driven hand-held machine tool (1), comprising
- a rotatably driveable tool bit (8) rotatable about a tool bit axis,
- a drive unit for rotating the tool bit (8) and including a motor (4), a transmission (5), a transmission housing (22), and a transmission output shaft (23) rotatable about an output shaft axis by the motor (4), wherein the motor (4), the transmission (5), the transmission housing (22), and the transmission output shaft (23) are aligned along the output shaft axis, and
- a tool-changing magazine (6), tool chambers (26) of which are displaceable into a position of handing off a tool bit held by a respective tool chamber to a tool fitting (7) to be loaded, wherein the tool-changing magazine (6) is rotatably supported on the transmission housing (22) of the drive unit in a displaceable manner, and wherein the motor (4) is completely spaced in the axial direction of the output shaft axis from the tool-changing magazine (6).
