摘要： A bearing device includes a rolling bearing having an outer ring and an inner ring, an outer ring spacer disposed adjacent to the outer ring, and an inner spacer disposed adjacent the inner ring. The outer ring and the outer ring spacer are fitted to a housing, and the inner ring and the inner ring spacer are fitted to a rotary shaft. The outer ring spacer is provided with a nozzle, which is configured to inject a cooling fluid (R) toward an outer circumferential surface of the inner ring, and is inclined so that an injection port thereof is inclined forwardly in a rotation direction of the inner ring. An inclination angle a of the nozzle with respect to an axial direction is set to a value within a range from 50° to 90°.

摘要： A retention housing for the outer race of a bearing of a gas turbine engine includes a spring finger housing connected to and overlying a bearing housing that is connected to the outer race of the bearing. The spring finger housing includes an arrangement of spring fingers that yields a lightweight housing capable of withstanding very high radial loads combined with very high torsional windup and axial thrust load. Dowel pins extending radially from the bearing housing and through the engine's interface shell limit the deflection and self-arrest the distortion of the housing. A gas turbine engine includes the retention housing described above.

摘要： A ball bearing retainer holds balls disposed between an inner ring and an outer ring, in pockets formed at a plurality of portions, in a circumferential direction, of an annular body. The annular body includes: annular parts disposed on both sides in an axial direction; and pillar parts that are disposed at a plurality of portions in the circumferential direction and that connect between the annular parts. The pockets are formed by the annular parts and the pillar parts adjacent to each other in the circumferential direction, and allow ball guide. First contact portions of the pillar portions, which contact portions contact with the balls in the circumferential direction, are formed by first planes that extend along the axial direction, and the balls are guided by the first planes.

摘要： A bearing device includes a shaft and a roller bearing externally inserted over the shaft. The roller bearing includes an inner ring disposed coaxially with a center axis of the shaft, an outer ring surrounding the inner ring from an outer side in a radial direction, and a plurality of rolling elements held between the inner ring and the outer ring to be capable of rolling. The inner ring includes an inner ring one half section disposed on one side in an axial direction and an inner ring other half section disposed on the other side in the axial direction. The inner ring one half section is in contact with the rolling elements from the one side toward the other side in the axial direction. The inner ring other half section is in contact with the rolling elements from the other side toward the one side in the axial direction. Preloads are applied to the inner ring one half section and the inner ring other half section in directions in which the inner ring one half section and the inner ring other half section come close to each other.

摘要： A ball bearing sleeve is used in a turbocharging device. The ball bearing sleeve has one or more ball bearings that are designed to control loads that are applied to the sleeve in the x, y and z-directions. The ball bearing sleeve is designed to replace the “thrust bearing” that is typically the “weak link” in a turbocharging device, as well as the journal bearings. The sleeve is designed to include a cylindrical portion that includes one or more grooves for directing the flow of oil around the sleeve for cooling. An oil duct having access holes directs the flow of oil into the ball bearings. Sleeve device may be retro-fitted into an existing turbocharger, which originally had journal and thrust bearings.

摘要： A rolling bearing includes an inner ring, an outer ring, a plurality of balls, and a cage that holds the balls. An annular groove for creep suppression is formed in a fitting surface that is fitted on a housing to which an outer ring is attached. The annular groove has a groove bottom portion and a pair of tapered surface portions extending from opposite sides of the groove bottom portion in an axial direction and defining a groove width that is larger toward the fitting surface. In a section including a bearing center line, each of the tapered surface portions has a linear sectional shape inclined to the fitting surface.

摘要： A plug assembly for use in a rolling bearing comprising at least a first ring, at least one second ring, and at least one row of rolling elements arranged between the rings. The first ring is provided with an opening for inserting rolling elements into a space between raceways or for taking rolling elements out of the space between the raceways for assembly and maintenance. The plug assembly comprises a plug configured to close the opening when the bearing is operating. The plug includes an inner end face facing the rolling elements and an outer end face opposite to the inner end face. The bearing can further comprise a protective cap shielding the outer end face of the plug from a corrosive environment of the bearing.

摘要： A rolling bearing includes an outer ring, an inner ring in which a shoulder diameter at one end of the rolling bearing in an axial direction is different from a shoulder diameter at the other end of the rolling bearing in the axial direction, a cage, a plurality of rolling elements, and shielding portions. A first clearance between an outer ring inner peripheral surface facing a large end of the inner ring having the larger shoulder diameter and a cage outer peripheral surface facing the outer ring inner peripheral surface is larger than a second clearance between an outer ring inner peripheral surface facing a small end of the inner ring having the smaller shoulder diameter and a cage outer peripheral surface facing the outer ring inner peripheral surface.
