A bearing device for a turbocharger according to one embodiment of the present invention includes: a rotational shaft; a journal bearing device including a compressor-side journal bearing and a turbine-side journal bearing; a bearing housing including a compressor-side bearing supporting portion, a turbine-side bearing supporting portion, and a bearing housing main body; and a lubricant oil guide member extending along a circumference direction of the rotational shaft, at an outer circumference side of at least one of the compressor-side bearing supporting portion and the turbine-side bearing supporting portion. When a virtual line extending vertically downward from a rotational center CL of the rotational shaft is defined as a reference line VL in a state where an oil discharge port is orientated downward, the lubricant oil guide member 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 θ about the rotational center CL of the rotational shaft.

The provided is a bearing device for a crankshaft of an internal combustion engine including: a crankshaft having a plurality of journal portions; main bearings for supporting the crankshaft; and a bearing housing, wherein a range in which the oil groove of the upper-side halved bearing of the second main bearing is formed in the circumferential direction includes at least a range of a circumferential angle of 20° within the ±45° region, a circumferential end portion of the oil groove on a rotationally forward side communicates with the crush relief at a minimum, and is open to a circumferential end face at a maximum, and a circumferential end portion of the oil groove on the rotationally backward side of the journal portion is positioned on a circumferential center portion side of the upper-side halved bearing from a circumferential end face of the upper-side halved bearing.

A bearing assembly for a charging apparatus. The bearing assembly comprises a bearing housing and a shaft. The bearing assembly further comprises a compressor-side bearing bushing and a turbine-side bearing bushing which together support the shaft inside a bearing bore of the bearing housing. The compressor-side bearing bushing is configured differently than the turbine-side bearing bushing.

A bearing element includes an inner surface (54) configured to receive a cylindrical shaft (18). The inner surface (54) includes a smooth profile having a plurality of sections (502). Each section (502) having a taper portion (506) between a first arc-span point (512) and a second arc-span point (514), a constant-radius portion (508) between the second arc-span point (514) and a third arc-span point (516), and a transition portion (510) between the third arc-span point (516) and a fourth arc-span point (518). An inner-surface radius dimension (520) changes from an inner-diameter major dimension to an inner-diameter minor dimension at the taper portion (506) and back at the transition portion.

A propulsion unit includes a housing supported on a vessel. A propeller shaft extends in the housing. The propeller shaft is rotatably supported with a first bearing and a second bearing. A propeller is attached to at least one end of the propeller shaft. The first bearing includes a first radial bearing and a first thrust bearing. The first radial bearing is a sliding bearing positioned axially inside the first thrust bearing. The first bearing is positioned at the first end of the housing and the second bearing being positioned at the second end of the housing or vice a versa.

A thrust bearing is described comprising first and second bearing assemblies (15, 17) rotatable relative to each and a plurality of axially arranged bearing stages (14a, 14b) formed between the first and second bearing assemblies (15, 17). Each bearing stage comprises a first load shoulder (16) provided on the first bearing assembly (15), a second load shoulder (18) provided on the second bearing assembly (17), a bearing structure (30) defined between the first and second load shoulders; and an extrudable component (32) forming part of the bearing structure. Wherein axial load applied between the first and second bearing assemblies (15, 17) in a first relative axial direction is transmitted between respective pairs of first and second load shoulders via the extrudable components (32) of respective bearing structures (30). The extrudable components (30) provide for load balancing between each bearing stage (14a, 14b).

A wind turbine rotary connection for two wind turbine components which are rotatable relative to each other, having a combined axial-radial bearing, wherein the axial-radial bearing has an axial bearing component and a separate radial bearing component. In particular it is proposed that the axial bearing component is in the form of a plain bearing component having a first convexly curved bearing surface and a corresponding second concavely curved bearing surface.
