Abstract: The tilting-pad bearing includes: a plurality of tilting pads arranged around a rotary shaft; a housing including a lubricating oil-supplying hole provided at a position facing a gap formed between the tilting pads disposed next to each other; and a pair of side plates disposed so that the tilting pads are interposed therebetween. The tilting pad is provided with an internal flow passageway through which lubricating oil flow. The internal flow passageway includes a first inflow opening, a second inflow opening, and a discharge opening.

Abstract: A flow volume measurement device for a turbo compressor includes a first pressure guide tube communicating with an intake pipe connected to a second compression stage having a compressor impeller that compresses a gas; and a second pressure guide tube communicating with an intake port of the second compression stage, which has a smaller internal diameter than an internal diameter of the intake pipe, and measures the flow volume of the gas on the basis of a difference in pressure between the first pressure guide tube and the second pressure guide tube.

Abstract: The present invention is a turbo machine that is provided with an impeller that is rotated, and with a shaft that transmits rotation power to this impeller, wherein there is provided a differential screw having an impeller screw portion that is provided at one end thereof and that is screwed into the impeller, and having a shaft screw portion that is provided at another end thereof and that is screwed into the shaft, and that fastens the impeller and the shaft together, and wherein, in the differential screw, a thread diameter of thread ridges that are formed on the impeller screw portion is formed the same as a thread diameter of thread ridges that are formed on the shaft screw portion, and a screwing direction of the thread ridges that are formed on the impeller screw portion is formed as the same direction as a screwing direction of the thread ridges that are formed on the shaft screw portion, and a pitch between the thread ridges that are formed on the impeller screw portion is formed smaller than a pitch

Abstract: The inner wall surfaces on the discharge sides of a cooling area have arc-like curved surfaces. The curvature of upper-side inner wall surfaces above a boundary part and the curvature of lower-side inner wall surfaces below the boundary part are set to be different from one another, the boundary part being located above the center line of cooling devices.

Abstract: An electric motor support structure (A) includes: a base (20) that has a cantilever support unit (21) and a mount unit (22), the cantilever support unit (21) supporting an electric motor main unit (11) with a first end part (13A) thereof in an axial direction being fixed and a second end part (13B) thereof being free, and the mount unit (22) having a support surface (24) that supports the second end part (13B) of the electric motor main unit (11); and a support member (30) that restricts relative movement between the electric motor main unit (11) and the mount unit (22) in an orthogonal direction parallel to the support surface (24) and also orthogonal to the axial direction and makes possible a relative movement between the electric motor main unit (11) and the mount unit (22) in a direction vertical to the support surface (24). With this electric motor support structure (A), it is possible to suppress vibration of the electric motor without applying an undue force to the cantilever support unit (21).

Abstract: A turbocompressor provided with a case, a centrifugal first stage and second stage compressing unit disposed on the case, and a driver unit for driving the first stage and second stage compressing units. The interior of the case is partitioned into a first cooling area which houses a first cooling device, a second cooling area which houses a second cooling device, an oil tank, and a blowoff silencer chamber. The blowoff silencer chamber is located between the oil tank and the first cooling area and the second cooling area in the interior of the case.

Abstract: In a turbomachinery (S1) that is provided with an impeller (1a) and a shaft (2) that are to be fastened, the impeller (1a) and the shaft (2) are fastened by a two-way screw (3) of which the turning direction of the screw thread that is formed on the impeller (1a) side and the turning direction of the screw thread that is formed on the shaft (2) side are opposite directions. As a result, it is possible to fasten the impeller (1a) to the shaft (2) without the need for a complicated and large equipment, and the amount of work during fastening is reduced.

Abstract: A casing provided centrally with a sealed structure chamber. Small-sized separate four filter elements are arranged each on opposite sides of the chamber such that inflow air from a suction section into the casing is introduced via the filter elements into the chamber. Each filter element is detachably fitted over a filter-element mount having openings at its outer periphery. Upon filter-element replacement, the filter elements are replaced individually by opening a window. An integral cast casing having compressing sections and compressed air passages integrally fabricated therewith by casting is formed with receptacles for first and second intercoolers and an aftercooler. The intercoolers and aftercooler are received in the receptacles. Outlets of the intercoolers are connected with suction sides of second- and third-stage compressors through second- and third-stage suction pipes, respectively. A blowoff silencer is arranged between the integral cast casing and an oil tank.
