摘要： A cage, which is annular, and is used in a thrust roller bearing, includes a plurality of cage segments arranged in a circumferential direction. Each of the cage segments includes an arc portion; and a bar portion that extends radially inward from the arc portion and that maintains a circumferential interval between rollers adjacent to each other. A groove portion extending along an axial direction is formed at each of end faces of the arc portions, the end faces facing each other in the circumferential direction. In the cage, elastic bodies are inserted into the groove portions and urge the arc portions in the circumferential direction, each of the elastic bodies is disposed between the end faces facing each other, and the cage segments are connected to each other by the elastic bodies.

摘要： There is realized a self-aligning roller bearing with retainer that stabilizes the orientation of spherical rollers and prevents these spherical rollers from skewing, and which can be rotated at high speed, and furthermore which enables efficient lubricant feed into pockets 9. By rotating a turning tool 14 as it revolves, the surfaces on both sides in the circumferential direction of respective column sections are processed into concave curved surfaces that oppose a rolling surface of the respective spherical rollers across a pocket clearance into which lubricant oil can be fed. The length of the column sections 8c is less than the length in the axial direction of the spherical rollers, and greater than a half of the length, and an end portion of the side surface in the circumferential direction of the respective column sections 8c projects further in the circumferential direction than an intermediate portion thereof, and the spherical rollers are embraced in the pockets 9.

摘要： A cylindrical roller bearing with synthetic resin cages, in which heat generation of the bearing during high speed rotation is suppressed, while sufficient rigidity and strength is secured, so that the bearing is excellent in high speed performance. The cylindrical roller bearing (10) has synthetic resin cages (20) each including an annular portion (21) disposed in one axial end portion of the cage (20), and a plurality of columnar portions (25) extending from a side surface of the annular portion (21). The minimum inner diameter d1 of the annular portion (21) is set to be smaller than the maximum inner diameter d2 of each columnar portion (25), and the inner diameter of the columnar portion (25) is set to be equal to the inner diameter d1 of the annular portion (21) over a range of length not longer than ⅔ of the whole length of the columnar portion (25).

摘要： The invention provides a roller bearing apparatus including an inner ring member supported for rotation on a sleeve, an outer ring member, rollers in the raceway space defined between the inner and outer ring members, and a guide member having roller seats against which inboard end portions of the rollers are seated. To promote roller precession when the roller bearing apparatus is used in an oscillatory application, the roller seats are slanted or pitched in a circumferential direction and at least the inboard end portions of the rollers are provided with non-planar, and in one embodiment frustoconical, end faces. Cooperation between the non-planar end faces of the rollers and the pitched roller seats controls the mean skew axes of the rollers to promote consistent roller precession through the bearing load zone, and enables increased freedom of movement of the rollers to minimize friction. This increases the life of the roller bearing by reducing roller related failures. Additionally, when the rollers precess the inner ring member is encouraged to rotate relative to the sleeve to bring new inner race surface portions into the load zone. This reduces inner ring-related failures.

摘要： A tapered roller retainer for tapered roller bearings in which the retainer is a one-piece molded body having a single flange supporting roller cage fingers. The roller cage fingers form reverse tapered pockets for the tapered rollers and the body of the retainer is sufficiently resilient to permit flexing of the cage fingers to facilitate insertion of the tapered rollers. The flexing of the tapered roller retainer with the reverse tapered roller pockets improves and facilitates bearing assembly methods.

摘要： 1,168,652. Bearings. TORRINGTON CO. 24 Oct., 1966 [24 Oct., 1965], No. 47558/66. Heading F2A. A roller cage comprises axial circumferentially spaced elements 13 of generally U-shaped crosssection, the limbs 15 of the U having end faces 16 for retainer rollers. In Fig. 3, elements 13 are connected by tabs 12 to an annular rim 11. The cage is formed from a disc of sheet metal by forming a ring of I-shaped openings (18, Fig. 2, not shown), removing the centre of the disc by piercing, and using a forming member to orientate elements 13. The cage is positioned in an outer race (21, Fig. 4, not shown) of U- shaped cross-section, the rollers being inserted into the race with the cage before the second limb of the race is bent over, or the rollers are snapped into the assembled cage. The limbs 15 of the elements 13 extend radially with respect to the axis of the abutting roller. The cage may be used in the bearings of an overrunning clutch.
