摘要： A bearing device 1 for a turbocharger according to one embodiment of the present invention includes: a rotational shaft 2; a journal bearing device 4 including a compressor-side journal bearing 41 and a turbine-side journal bearing 42; a bearing housing 6 including a compressor-side bearing supporting portion 61, a turbine-side bearing supporting portion 62, and a bearing housing main body 66; and a lubricant oil guide member 10 extending along a circumference direction of the rotational shaft 2, at an outer circumference side of at least one of the compressor-side bearing supporting portion 61 and the turbine-side bearing supporting portion 62. When a virtual line extending vertically downward from a rotational center CL of the rotational shaft 2 is defined as a reference line VL in a state where an oil discharge port 64 is orientated downward, the lubricant oil guide member 10 extends from the reference line VL along the circumference direction toward each of one side and another side of the reference line VL over a predetermined angle ¸ about the rotational center CL of the rotational shaft 2.

摘要： An oil-drain device for a thrust bearing includes: a rotor shaft 2; a collar member 3 mounted to an outer periphery of the rotor shaft; a thrust bearing 4 supporting the rotor shaft in an axial direction; and an oil-drain space forming member 5 defining an oil-drain space 6 through which lubricant oil leaking from a sliding portion of the thrust bearing flows, between the thrust bearing and the oil-drain space forming member. The oil-drain space 6 includes: an oil-drain channel 6A defined between a first end surface of the thrust bearing and a first end surface of the oil-drain space forming member, surrounding the flange portion 32 of the collar member 3; and an oil-drain port 6B formed below the oil-drain channel 6A, for discharging the lubricant oil flowing through the oil-drain channel outside the oil-drain space. The oil-drain space is configured to guide the lubricant oil flowing through the oil-drain channel to outside the oil-drain space 6 via the oil-drain port 6B, along a flow direction f of the lubricant oil flowing through the oil-drain channel 6A from an upstream side toward a downstream side in a rotational direction R of the rotor shaft 2.

摘要： A rotary machine (1) is provided with: a flange section (16) protruding in the radial direction of a rotating shaft (5) which rotates about an axis (O) and rotating together with the rotating shaft (5); a stationary bush (13) disposed at a distance in the direction of the axis (O) from the flange section (16), surrounding the outer peripheral surface of the rotating shaft (5), and provided in a housing (4) supporting the rotating shaft (5) so as to be immovable in the direction of the axis (O) relative to the rotating shaft (5); and a rotation bush (10) which is disposed between the flange section (16) and the stationary bush (13) so as to be sandwiched therebetween in the direction of the axis (O), covers the outer peripheral surface of the rotating shaft (5), and is rotatable relative to the rotating shaft (5) and the housing (4) while floating in fluid (OI). The rotation bush (10) has, on the surface thereof which faces the direction of the axis (O), a land surface (25) and a tapered surface (26) which is continuous with the land surface (25).
