A supercharging device, for example an exhaust gas turbocharger, may include a rotor mounted in a housing via an axial bearing. The axial bearing may include an axial bearing disc, a membrane, and a screw connection that secures the axial bearing disc to the membrane through an opening in the membrane. The axial bearing may further include a bush connected to the housing. The membrane may be clamped in between the bush and the housing. An adjusting screw may be inserted into an opening of the bush. The adjusting screw may delimit and/or facilitate an axial movement of the screw connection and the axial bearing disc.

A damping bearing (20) including an inner ball portion (34) attached to an end of a support shaft (32), and an outer collar portion (30) attached to a housing (22) for rotation of the housing relative to the support shaft about a center point. A chamber (28) for a damping fluid such as grease is defined by clearance between the end of the shaft and the housing. The fluid chamber has opposed bounding surfaces (29, 37) that are non-spherical about the center of rotation so that the chamber changes shape upon rotation of the bearing, thus shifting damping fluid across the chamber. The chamber may be a flat cylindrical void normal to a centerline (33) of the shaft. It may provide only enough clearance for less than ±10 of relative rotation between the housing and shaft. A set-screw (26) may pressurize the fluid in the chamber.

The present invention addresses the problem of providing a rotary shaft supporting structure which is capable of supporting a rotary shaft for a longer period. This rotary shaft supporting structure, which supports a rotary shaft on which a thrust collar that protrudes outwards in the radial direction is formed, has: thrust bearings which face the thrust collar, and support, using support surfaces, the thrust collar surfaces that are orthogonal to the axial direction of the rotary shaft; and support mechanisms which support the thrust bearings in the axial direction from the surface side of support surfaces at the opposite side to the thrust collar. The sides of the support mechanisms that face the end surfaces of the thrust bearings are inclined in the direction orthogonal to the direction in which the rotary shaft tilts.

An inner half-ring of a spherical plain bearing has a spherical outer surface, a cylindrical inner surface, and a first flat front face and a second flat front face delimiting the half-ring in a circumferential direction. The first and second flat front faces extend between the outer surface and the inner surface, and a first central groove is formed in the first front face and extends between the outer surface and the inner surface.

A rotor bearing for bearing a rotor hub on a nacelle housing of a nacelle for a wind turbine has at least one inner ring element and at least one outer ring element, wherein at least one sliding bearing element is arranged between the inner ring element and the outer ring element, which sliding bearing element is fastened to the inner ring element or to the outer ring element. On the sliding bearing element, a sliding surface is formed, which cooperates with a counterface, which is coupled with that ring element, to which the sliding bearing element is not fastened. The counterface is designed to be resilient.

Systems and methods related to hydrodynamic bearings for use in X-ray sources are provided. In one aspect, a hydrodynamic bearing system includes a sleeve assembly including a cross-member fluidically dividing a first interior cavity from a second interior cavity, a first shaft positioned in the first interior cavity, and a second shaft positioned in the second interior cavity. The hydrodynamic bearing system may further include a first journal bearing including a first fluid interface surrounding at least a portion of the first cantilever shaft and configured to support radial loads and a second journal bearing including a second fluid interface surrounding at least a portion of the second cantilever shaft and configured to support radial loads.
