Abstract

The invention relates to a rock drilling machine, a rotary sleeve and a lubrication method for lubricating a drill 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 has a lubricating system (23) for lubricating the gears and the bearings (15) of the rotating sleeve.

Description

technical field [0001] The present invention relates to a rock drilling machine, and in particular to a device for lubricating the same. A rotary sleeve is arranged around the drill shank to transmit the rotation generated by the rotary device to the drill shank. Rotary quills and shanks have a transmission system to transmit the rotation. Additionally, the rock drilling machine includes a lubrication system to feed pressurized lubricating fluid to the transmission system. [0002] The invention further relates to a rotating sleeve and a method of lubricating a rock drilling machine. Background technique [0003] In mines and other workplaces, rock drilling machines are used to drill boreholes into rock surfaces. The rock drilling machine includes a rotary device for rotating the drilling tool during drilling. The tool is connected to a drill shank which is support mounted to the body of the drill. The rotating torque generated by the rotating device is transmitted to t...
