Claims

[Scope of utility model registration request]

a runner fixed to a rotating shaft and divided into a plurality of pieces in the circumferential direction; a bearing shoe 7 that makes sliding contact with the runner; a pivot that swingably supports the bearing shoe;
an annular bracket supporting the pivot via a frame and having a triangular cross section, the bracket surrounding the bearing shoe and being provided in an oil tank in which lubricating oil is stored; In a thrust bearing device in which the cooled lubricating oil is supplied and discharged through a circulation pipe to the sliding surfaces of the runner and the bearing shoe, the inside of the bracket is divided into two rooms, a cold oil chamber and a hot oil chamber. the circulation pipe is connected to a pipe that passes through an outer wall of the bracket cold oil chamber and supplies the cooled lubricating oil into the bracket cold oil chamber and an inner wall of the bracket cold oil chamber; An oil supply pipe consisting of a branch pipe that supplies the cooled lubricating oil in the bracket cold oil chamber to the sliding surface.
and an oil drain pipe that penetrates the outer wall of the bracket hot oil chamber and drains the lubricating oil in the oil tank that has cooled the sliding surface. .
