Zusammenfassung:	The invention relates to a rock drilling machine, a rotating sleeve and a method of lubricating a shank of the rock drilling machine. The rock drilling machine (4) comprises a rotatable shank (6) for connecting a drilling tool (7). The shank is rotated by a rotating sleeve (14) arranged around the shank. Gears (43, 44) are arranged between the shank and the rotating sleeve. The rock drilling machine is provided with a lubricating system (23) for lubricating the gears and also bearings (15) of the rotating sleeve. Linvention a trait à une machine à forer la roche, un manchon tournant et un procédé de lubrification dune tige de ladite machine. La machine à forer la roche (4) comprend une tige rotative (6) permettant de raccorder un outil de forage (7). Un manchon tournant (14) disposé autour de la tige fait tourner cette dernière. Des engrenages (43, 44) sont disposés entre la tige et le manchon tournant. La machine à forer la roche est pourvue dun système de lubrification (23) pour lubrifier les engrenages et les paliers (15) du manchon tournant.
