  • Publication number: 20180216662
    Abstract: The disclosure relates to a method for producing an angular contact roller bearing with unilaterally delimiting rims. The disclosure also relates to multiple variants of a device for assembling the angular contact roller bearing. The method may include conically forming an inner raceway into a cylindrical section of an outer shell surface of an inner bearing ring such that the inner raceway is inclined relative to the bearing axis of rotation (AL) and is delimited at one end by a rim, conically forming an outer raceway into a cylindrical section of an inner shell surface of an outer bearing ring such that the outer raceway is inclined relative to the bearing axis of rotation (AL) and is delimited at one end by a rim, and assembling the inner and outer bearing rings and a multiplicity of roller-type rolling bodies, which roll on the raceways of said bearing rings, in accordance with an eccentric assembly method.

  • Publication number: 20150285304
    Abstract: A ball roller bearing (1) formed from a plurality of ball rollers (4) arranged between an outer bearing ring (2) and an inner bearing ring (3) and each of which comprises two parallel lateral surfaces (5, 6) and rolls, with their running surfaces (7) extending between said lateral surfaces (5, 6), in two groove-shaped raceways (10, 11) in an inner side (8) of the outer bearing ring (2) and the outer side (9) of the inner bearing ring (3), and which are held within individual cage pockets (12) of a bearing cage (13). The bearing cage (13) includes two interconnected lateral rings (15, 16) and two cage ribs which are connected thereto and in guiding contact with these lateral surfaces (5, 6) for axially guiding the ball rollers (4).

  • Patent number: 8690447
    Abstract: A ball roller bearing, which has an outer and inner bearing ring with a groove-shaped raceways and ball rollers, which roll between the bearing rings in the raceways. The rollers are held at distances from each other in the circumferential direction by a bearing cage and which have a width that is dimensioned larger than the radial distance between the inside and the outside of the bearing rings. The raceways are divided into two segments by an axially centered annular groove such that a first ball roller rolls on two first diagonally opposed track segments and a second ball roller rolls on two second diagonally opposed track segments of the bearing rings. Both bearing rings are single-piece components, and the bearing cage is formed by two identical double prong-type cages acting independently of each other. The bearing is filled with the ball rollers by an axial tilt cam assembly method.

  • Patent number: 8596873
    Abstract: A roller bearing which has an outer and inner ring and ball rollers arranged between the rings, which roll in two groove-shaped tracks in the outer and inner rings and are held at a uniform distance to one another by a window cage that has two lateral ribs bent around two circumferential flanged edges to the inner ring and interconnected by pocket bridges. The cage pockets of the cage ribs have a hole formed from a cross-sectional contour of a ball roller arranged longitudinally to the circumferential direction and from a free contour incorporated therein and arranged perpendicular to the circumferential direction. The free contour in each cage pocket is expanded to a rectangle and the flange edges of the ribs each have reduced material thickness compared to the other material thickness of the cage by a circumferential, line-shaped burnishing.

  • Patent number: 8480307
    Abstract: A ball roller bearing which has an outer and inner bearing ring and ball rollers arranged between the rings, which roll in groove-shaped tracks in the rings and are held at a uniform distance to one another by a window cage. The cage has two lateral angle ribs, pocket bridges, which connect the ribs and cage pockets separated by the pocket bridges. The pockets have a cross-shaped hole formed from a contour perpendicular to the circumferential direction and a cross-sectional contour of a ball roller arranged longitudinally to the circumferential direction. The side edges are formed from the pocket bridges, which have radii of arch-shaped guide surfaces corresponding to the running surfaces of two ball rollers. The pocket bridges have additional material profiling between the side edges and on the guide surfaces for axial stiffening of the cage and damping bearing noise.

  • Patent number: 8382379
    Abstract: A ball roller bearing and to a method for the installation thereof. The ball roller bearing has an outer bearing race, and an inner bearing race, and a plurality of ball rollers, which are disposed between the bearing races and are held at equal distances to each other by a bearing cage. For this purpose, the ball rollers have a width of approximately 70% of the diameter of a spherical shape thereof, and roll with bearing surfaces thereof in two groove-shaped raceways, the depth of which is smaller than the distance between the outer and inner bearing race. The cage pockets of the bearing cage have a cross-sectional contour of a ball roller disposed in the longitudinal and transverse directions to the circumferential direction. The method for installation of the ball roller bearing is a cross/oblique pivot mount between the inner and outer bearing races and the ball rollers.

  • Publication number: 20030234064
    Abstract: Corrosion-resistant welding electrodes made of tungsten or a tungsten alloy are produced. Prefabricated welding electrodes are heat treated at temperatures of between 300° C. and 500° C. in an oxidizing atmosphere. This results in the formation of oxide layers on the surface of the welding electrodes; these layers have good electrical conductivity and prevent the formation of unwanted corrosion layers with poor conductivity. Welding electrodes produced in this way demonstrate outstanding spark ignition and problem-free erosion.

  • Patent number: 6398634
    Abstract: The present invention comprises a drilling tool for attachment to conventional drilling means, which roughens the internal surface of a pre-drilled hole to enhance attachment of an anchoring device and adhesive placed therein. The roughening device has a shaft for attaching to a conventional drilling device at one end and a tubular side wall bearing cutters/abraders at the other. There is a void between the shaft and the side wall which is filled by an elastomeric material which cushions the action of the cutters/abraders.
