Abstract (en)
[origin: EP3812097A1] A rotary hammer (101) includes a spindle, a motor, a first intermediate shaft (41), a striking mechanism (6), a second intermediate shaft (42) and a rotation-transmitting mechanism (7). The motor shaft extends in a direction intersecting a driving axis. The first intermediate shaft (41) extends in parallel to the driving axis. The striking mechanism (6) converts rotation of the first intermediate shaft (41) into linear motion and linearly drives a tool accessory along the driving axis. The rotation-transmitting mechanism (7) transmits rotation of the second intermediate shaft (42) to the spindle and rotationally drives the tool accessory around the driving axis. The motor shaft rotates the first intermediate shaft (41) via a driving bevel gear and a driven bevel gear (414). The first intermediate shaft (41) rotates the second intermediate shaft (42) via a driving gear (415) and a driven gear (424).
