摘要： A thrust bearing (3) includes: a top foil (10) formed of top foil pieces (11) which face a thrust collar (4); a back foil (20) formed of back foil pieces (21) which support the top foil pieces; and a base plate (30) including support areas (31) which support the back foil pieces. A support area includes an inclined surface (32) defined by a first boundary line (31b) and by a second boundary line (31a) disposed on a trailing side of the first boundary line in the rotational direction of the thrust collar. The height of the inclined surface gradually increases from the first boundary line to the second boundary line. In addition, a back foil piece is disposed within the inclined surface which is formed continuously from the first boundary line to the second boundary line.

摘要： A thrust bearing (3, 3A, 3B) disposed facing a thrust collar (4) provided on a rotary shaft (1) includes: a top foil (10) disposed facing the thrust collar; a back foil (20) supporting the top foil; and an annular shaped base plate (30) supporting the back foil. The back foil includes back foil pieces (21), and the top foil includes top foil pieces (11). An area on the leading side of a top foil piece in the rotation direction of the rotary shaft is provided with a fixed part (13) fixed to the base plate. A fixed edge (12) positioned on the trailing side of the fixed part in the rotation direction linearly extends such that the separation between a straight line extending in the radial direction of the base plate and the fixed edge positioned on the trailing side of the straight line in the rotation direction gradually increases outward from inside in the radial direction.

摘要： The invention relates to a fluid flow machine, comprising a housing (1) and a connecting piece (1) for a working fluid (9) on an intake side and a pressure side, comprising at least one impeller (3) on a shaft (4), which is held in the housing (1) with radial bearings (5, 6) and an axial bearing (7), and a cooling arrangement for at least one bearing (5-7). The object of the invention is to develop a fluid flow machine, which enables improved efficiency and an improved cooling effect of bearings with little effort. According to the invention, a revolving part (13) of the axial bearing (7) is designed as a cooling fluid transportation device, wherein a suction connection leads to the intake side of the impeller (3). A preferred use of the fluid flow machine provides for the use thereof as part of an electric turbocharger, which in particular supplies a fuel cell system with an oxidizing agent.

摘要： An improved foil thrust bearing (10) includes a cooling fluid flow turbulence generating disk (18) placed between other foil thrust bearing elements, such as thrust bearing elements (16) and underspring elements (20). The inventive turbulence generating disk (18) generally provides improved transfer of heat through the foil and into the cooling fluid of foil thrust bearings (10) that may be used for high rotor speed applications. It accomplishes this by improving the transfer of heat through the foil and into the cooling fluid by generating turbulent cooling flow adjacent to the back of the top foil (16). The turbulent flow is generated primarily by a series of turns or protrusions introduced into the cooling flow stream. Alternate embodiments are disclosed that provide the turbulence generating elements as part of the underside of thrust bearing elements.

摘要： A hydrodynamic bearing set, for use with a thrust disk (11) disposed between planar surfaces (22, 32) of a housing (20), includes first and second topfoils (21, 23) disposed adjacent first and second thrust disk axial bearing surfaces (12, 13) and removably secured to the housing. An underspring (25, 27) is secured between each planar housing surface and the corresponding topfoil. Dual-leaf spring pairs (41) attached to at least one topfoil periphery function to urge the topfoils (21, 23) away from the thrust disk axial bearing surfaces (12, 13) by applying a force against a planar housing surface, another topfoil, or a spacer washer secured between adjacent topfoil dual-leaf pairs or frictionally retained within the housing. Alternatively, a wavy washer, a conical spring, a Belleville washer, or a coil spring can be substituted for the dual-leaf spring pairs.

摘要： A compliant foil fluid thrust bearing has a single sided or two sided thrust disk (24) rotor, an integrally formed compliant foil member (40), and an underspring member (42). The non-rotating but compliant foils are located adjacent to the thrust face of faces or the rotatable disk and are formed as arcuate segments on washer-shaped disk members. The underspring member consists of three washer-shaped disk elements that together provide variable spring stiffness in both the circumferential and radial directions.
