Abstract: An exhaust turbocharger including a modular bearing designed for bearing a shaft and arranged between a compressor and a turbine is provided herein. The bearing has a bearing housing having a receptacle chamber, wherein a bearing assembly module can be or is installed in the receptacle chamber and can be non-destructively removed. The receptacle chamber is sized such that either a bearing assembly module having a rolling bearing or a bearing assembly module having a slide bearing can be installed. The receptacle chamber has an interface, designed to contact the bearing flange of a bearing assembly module inserted into the receptacle chamber. The interface is designed to connect an oil gallery passing through the bearing housing to one or more oil galleries passing through a bearing flange of the bearing assembly module.

Abstract: A radial bearing arrangement of an exhaust gas turbocharger for mounting a shaft in a bearing housing is disclosed. The radial bearing arrangement comprises a radial bearing bush arranged between the shaft and the bearing housing, wherein the radial bearing bush features a radially outwardly projecting collar, which interacts in the axial direction with an axial stop on the bearing housing. The geometry of the radially outwardly projecting collar is interrupted by cut-outs, such that a force acting on the collar as a result of an oil feed pressure is minimized, and wherein the radial bearing bush is configured such that a lubricating film can form between an end surface of the radial bearing bush and a counterpiece arranged on the shaft.

Abstract: The invention relates to a radial bearing arrangement (110) of an exhaust gas turbocharger (100) for mounting a shaft (120) in a bearing housing (130). The radial bearing arrangement (110) comprises a radial bearing bush (140) arranged between the shaft (120) and the bearing housing (130), wherein the radial bearing bush (140) features a radially outwardly projecting collar (141), which interacts in the axial direction with an axial stop (131) on the bearing housing (130). The geometry of the radially outwardly projecting collar (141) is interrupted by cut-outs (142), such that a force acting on the collar (141) as a result of an oil feed pressure is minimized, and wherein the radial bearing bush (140) is configured such that a lubricating film can form between an end surface (144) of the radial bearing bush (140) and a counterpiece (160) arranged on the shaft (120).

Abstract: A hydrodynamic axial bearing for mounting a shaft which is mounted rotatably in a bearing housing, including an axial stop of the bearing housing and a bearing comb which rotates with the shaft. A lubricating gap, which is loaded with lubricating oil and is delimited by a profiled circular ring face and a sliding face, being formed between the axial stop and the bearing comb. The profiled circular ring face and the sliding face are configured in such a way that the lubricating gap is constricted radially to the outside with regard to the axial direction. As a result, temperature deformations which occur during operation and deformations on account of centrifugal, shearing and other forces in the bearing comb can be compensated for.

Abstract: A hydrodynamic axial bearing with a floating disk is disclosed wherein two lubricating gaps on the two sides of the floating disk are formed by supporting surfaces of different size. This makes it possible to provide identical lubricating gaps on both sides, despite different rotation speeds between the floating disk and the bearing housing, and between the floating disk and the bearing comb.

Abstract: An overvoltage protection for a coaxial line has a coaxial line section with a first inner conductor which is concentrically surrounded by an outer conductor, with a first branch line in the form of a short-circuit line with a second inner conductor branching off from the coaxial line section in the radial direction, and with the inner conductor being accommodated in a first recess in the outer conductor of the coaxial line section.

Abstract: The system (1) is installed in a coaxial line for the transmission of high-frequency signals. It serves for the purpose of protecting apparatus or installations against electromagnetic pulses, overvoltages and/or lightning strokes. The system (1) comprises shortcircuit lines (5, 6), which are disposed approximately parallel to the inner conductor (3) of the coaxial line. This disposition makes possible to develop the housing (2) of the system (1) concentrically to the longitudinal axis (9) and the housing (2) has no projecting elements.

Abstract: In a hydrodynamic axial bearing (10), a rotating body (13) is mounted radially in a radial bearing (17) of a bearing body (18). The rotating body (13) comprises a shaft (16), with its shaft journal (14) mounted in the radial bearing (17), and a bearing collar (20) which is connected fixedly to the shaft (16) and corotates with the shaft (16). A floating disk (12) is arranged in an annular-groove-shaped space (28) between a wall (26) of the fixed bearing body (18) and a projection (22) of the corotating bearing collar (20). The floating disk (12) has a central circular orifice (30) which is designed as an integrated hydrodynamic radial bearing (32). By means of this radial bearing (32), the floating disk (12) is mounted radially on a fixed bearing element (38) concentrically surrounding the rotating body (13) on a portion (29).
