ABSTRACT:
The invention relates to a damping device for an output shaft (26) in a gearbox (14, 16), where the gearbox (14, 16) is arranged for rotation of a rotational degree of freedom (Z4,Z5) in a rock-drilling rig (2), and thus for positioning of the same, and where the damping device (18) comprises a brake (38) that acts on the output shaft (26) of the gearbox (14, 16), which brake (38) acts as an oscillation damper for the movement of the output shaft (26), whereby a gearbox (14, 16) with play can be used for applications that require a high degree of precision such as positioning, e.g. measuring a position for a drill hole. The invention also relates to a gearbox (14, 16) and a rock-drilling rig (2) with damping device (18), respectively.
