摘要： When an inner-diameter-side opening of each of a plurality of radial holes (15) in an outer race (12) is projected onto an outer circumferential surface of a retainer (14) along an extension line of the center line (XI, X2) of the radial hole (15a, 15b), at least a portion of the inner-diameter-side opening of the radial hole is located, in the axial direction, within a region between two circles each formed by connecting axial-direction ends of adjacent pockets in the retainer (14). When the center line (X1) of one of the radial holes (15a) matches the phase, in the circumferential direction, of the center (O) of a ball (13), a projection of the inner-diameter-side opening (30) of one of the other radial holes (15b), when the inner-diameter-side opening thereof is projected as described above, is separated from the ball (13) and the inner circumferential surface of the pocket (P) as viewed from the radial direction of the ball bearing (10), and the center line of said one of the other radial holes overlaps said pocket as viewed from the axial direction of the ball bearing.

摘要： A wheel hub unit comprises a wheel hub body (100, 200), a first tapered roller bearing (101, 201) and a second tapered roller bearing (102, 202). Two bearings are oppositely disposed in the wheel hub body (100, 200). A bearing bush (104) or a shaft sleeve (204) is sleeved in the inner rings of the first tapered roller bearing (101, 201) and that of the second tapered roller bearing (102, 202), so as to form a rolling and sliding bearing, and the high strength load is effectively absorbed, the occurrence of the problems that a rolling body slides on the inner rings of the bearings, that the high temperature is generated, and then fatigue pitting is on the inner rings of the bearings is avoided. At the same time, a seal element is disposed between the outside end of the bearing and the wheel hub body (100, 200) to form the integral type independent seal. The problem that the inner rings of the bearings are exchanged and assembled in a mixed way during the assembly process is avoided, and the efficiency and accuracy of assembly are improved.

摘要： A positioning protrusion 14 is provided in a center of an outer diameter surface of a halved outer ring 11a in both circumferential and axial directions. The positioning protrusion 14 is configured to engage with a housing, which is placed on an outer diameter side of the halved outer ring, to position the halved outer ring 11a with respect to the housing. A protruding portion 17a and a recessed portion 17b are provided in each abutting portions 16a, 16b where a pair of the halved outer rings 11a abut on each other when fitted on a rotary shaft that is supported by a roller bearing. The protruding portion 17a and the recessed portion 17b are configured to mesh with each other to restrict axial movement of both halved outer rings 11a. The protruding portion 17a and the recessed portion 17b are point-symmetric with respect to a center 20 of the positioning protrusion 14.

摘要： An exemplary gas turbine engine (10) includes a radially stacked intershaft bearing assembly (38). The assembly (38) includes an outer stubshaft (60) having outer and inner diameter surface portions (66, 68) disposed concentrically with respect to one another. The outer diameter surface portion (66) is rotatably connected to a body (36) of the engine (10), and the inner diameter surface portion (68) is rotatably connected to an inner stubshaft (56) of the engine (10), so as to provide a stacked configuration of the inner stubshaft (56), the outer stubshaft (60), and the body (36) along a radial direction (64) orthogonal to a longitudinal axis (34) of the engine (10).
