ROCK DRILLING UNIT, FEED BEAM, AND METHOD FOR DAMPING VIBRATION

摘要

The invention relates to a rock drilling unit, feed beam,and method for damping vibration in a rock drilling unit.In the rock drilling unit (3),a damping element (13) is arranged between the joint surfaces of two inter-connected components to damp vibration and prevent its transmission on in the structure of the drilling unit. The feed beam (6) may be divided into two or more parts (6a, 6b) with a damping element of possibly elastic material arranged between them.
