  • Patent number: 9181983
    Abstract: The invention relates to a method for lubricating and cooling a bearing that is subject to high loads and to a device for carrying out said method. The invention is characterized by dissolving a lubricant in a supercritical gas that is cooled down to a low temperature and feeding the gas/lubricant mixture to the baring. The gas/lubricant mixture is relaxed in the bearing area, thereby releasing the lubricant and lubricating the bearing. The now subcritical gas that is cooled down to a low temperature is used for cooling and is discharged to the exterior. The gas used is carbon dioxide (CO2) and the lubricant is a hydrocarbon-based lubricant.

  • Patent number: 5028150
    Abstract: An anti-friction bearing unit, particularly for use in an exhaust gas turbo charger. The unit includes two anti-friction bearings axially spaced apart from each other on a shaft. High temperature occurs on one end of the shaft. A precise mounting is provided which is not sensitive to high temperatures on at least the axial side exposed to high temperature. The bearing outer ring, which is the ring not subject to high temperatures, consists of one piece. The bearing inner ring is widened and divided into two sections at its axial middle. The axial portion of the divided inner ring which is exposed to high temperature consists of material of high heat resistance. The high heat resistance material is, for example, 80 MoCrV 42 16 (M 50) or X 102 CRMo 17 (AISI 440 C). An additional intermediate ring around the shaft at the high temperature and helps reduce heat transmission.

  • Patent number: 4886379
    Abstract: A cage for a ball bearing comprised of two generally ridge-shaped ring parts, the respective axially projecting ridges of which are cooperatively placed to define respective pockets for the balls. The plane of separation between the two ring parts is shifted axially off the center and toward one of the ring parts. In the ring part with the axially larger ridges, the circumferentially opposite ends of the respective ridges are at least nearly flat, in the plane through the centers of the balls. The axially deepest surfaces of the ridges are also at least nearly flat, at the axially opposite sides of the cage, which is generally in the respective axial plane through the center of each ball. This prevents jamming of the balls, even in the case of defective manufacture or defective connection of the ring parts.

  • Patent number: 4714358
    Abstract: A cage for lipless roller bearings, in which two rows of bearings are separated and supported by a support ring that is wedge- or cusp-shaped in cross-section at the longitudinally inward ends of the roller rows. The support ring surfaces facing the roller ends are so shaped (e.g. having a surface that is inclined to the roller end, or having a larger radius of curvature than the curved roller end, with the axes of curvature being placed inward of the roller axes) that there is defined a lubrication-receiving space between the support ring and the ends of the supported rollers which increases in width toward the radial interior of the bearing, to improve lubrication characteristics. Advantageously the cage may be used with a lipless self-aligning roller bearing, or a lipless conical or tapered roller bearing.

  • Patent number: 4609293
    Abstract: The disclosure concerns an anti-friction bearing between a rotating shaft and an external bushing. The bearing includes two axially spaced apart rows of bearing balls. A feed bushing is disposed in the space between the shaft and the external bushing and between the two rows of bearings. The feed bushing is open at the axial ends for dispensing lubricant to the rows of bearings at the axial ends of the feed bushing. The feed bushing holds lubricant, such as grease, in itself for being dispensed at the axial ends of the feed bushing. A porous elastic material may be disposed in the feed bushing for being impregnated with the lubricant. The feed bushing, and also the porous material if used, are elastic and resilient to permit deflection of the shaft with respect to the external bushing. Various shape and configuration feed bushings are disclosed. A lubricant recharging hole passes through the external bushing and communicates to the feed bushing.
