PURPOSE:To enable the lubrication of the sliding surface of bearing shoe without engagement with the frame to achieve greater ease of the disassembly and reassembly of bearing shoes by making it possible to supply a lubricating oil to the sliding surface of bearing shoe through a passage leading through an oil tank from inside a bracket. CONSTITUTION:An oil supply pipe 8 is formed with pipe 8f which has one end placed inside bracket 6 and delivers cooled lubricating oil 8', ring header 8g provided at the distal end of the pipe 8f, and branch pipe 8h which passes through the inside partition of bracket 6 to connect ring header 8g and the sliding surface of bearing shoe. That is to say that the pipe 8f to carry the lubricating oil 9' cooled by a cooler P is so arranged that its distal end is located inside the triangular body of the bracket 6 and is fitted with the ring header 8g. The branch pipe 8h connecting the ring header 8g and the sliding surface of the bearing shoe 3 is so arranged that it passes through the inside partition of the bracket 6. |
