<p>Drilling device comprises an oscillator housing (10) on which a first bearing shell (30) is arranged, and an oscillator (11) on which a second bearing shell (32) is arranged. The surfaces of the bearing shells that are pressed together are designed as running surfaces (31, 33) for a rolling body (34). One bearing shell can be inclined relative to the drilling direction (53) so that the oscillator produces an oscillating movement in the drilling direction when the two bearing shells are rotated relative to each other. A stroke-adjusting device (43) for adjusting the angle of a bearing shell acts on a specified force-application surface (45) on the side of the bearing shell facing away from the running surface.</p> |
