Abstract

1449758 Lubricating; flushing in rock drills ATLAS COPCO AB 15 July 1974 [2 Aug 1973] 31205/74 Heading B3C [Also in Division B4] An hydraulic drill comprises a flush chamber 29 surrounding a tool 11 and two air pressure chambers one at the bearing 41 and the other at the bearing 24 which prevent the dust from entering into the drill. As shown flushing water enters through a pipe 32 to a chamber 29 and exits through bore 10 in drill 11. Pressure air plus lubricating oil enters through pipe 42 and channels 44-46. The pressure air exits from pipe 45, 44 into a chamber containing spring 22 and exits adjacent drill 11 and pipe 48. Air exits from the front chamber between the housing and drill 11. Bearings 17, 18 are packed with grease and kept separate from the air and water supplies. A rotary motor 16 is supplied. Seals 6, 7 on piston-rod 4 prevent movement of unwanted fluids and particles to and from the hydraulic drive section 2.
