PURPOSE:To easily perform mounting and removal of a bearing shoe, by extending supply and discharge oil pipes through external and internal walls of a bracket and forming a circulative pipe line through the supply and discharge oil pipes. CONSTITUTION:A circulative pipe line is formed by a supply oil pipe 8h, comprising a pipe 8a, extending through an external wall 6a of a bracket 6 and supplying cooled lubricating oil 9a into a bracket 6, and a branch pipe 8g, connected to an internal wall 6b of the bracket 6 and supplying the cooled lubricating oil 9a in the braket 6 to a sliding surface, and discharge oil pipe 7d (7a, 7c), extending through the internal and external walls 6b, 6a of the bracket 6 and discharging the lubricating oil 9a in an oil tank 9 having cooled the sliding surface. In this way, the lubricating oil 9a can be supplied and discharged by the supply and discharge oil pipes 8h, 7d, which are not engaged to a frame 5, then mounting and removal of a bearing shoe 3 can be performed without being disturbed by the circulative pipe line, thus disassembly and assembly work of the shoe can be facilitated. Further a trouble of oil leakage can be also eliminated. |
