    摘要: A ball bearing with double raceway rotatably supports a pinion shaft having a pinion gear on its one end. This ball bearing with double raceway is provided with: an outer ring member having a large-diameter raceway surface and a small-diameter raceway surface; an inner ring member having a large-diameter raceway surface and a small-diameter raceway surface that correspond to the large-diameter raceway surface and the small-diameter raceway surface of the outer ring member; a large-diameter-side row of balls that are interpolated between the two large-diameter raceway surfaces; a small-diameter-side row of balls that are interpolated between the two small-diameter raceway surfaces; a large-diameter-side cage that holds the large-diameter-side row of balls; and a small-diameter-side cage that holds the small-diameter-side row of balls. In this ball bearing with double raceway, the row of balls on the anti-pinion gear side of the two rows of balls is subjected to a load prior to the row of balls on the pinion gear side.

    摘要: In a double row ball bearing disposed around a pinion shaft to support the same, at least an inner ring member out of its inner and outer ring members is applied to a carbonitriding surface treatment, and hardness of at least inner ring raceway surfaces of the inner ring member is substantially the same as hardness of balls. With this construction, the bearing has an excellent load-withstanding performance, so that the lifetime of the bearing is prolonged.

    摘要: In a bearing device, a double row rolling bearing for supporting a pinion gear-side portion of a pinion shaft on a case (annular wall) is formed by a tandem-type double row angular contact ball bearing. A first row of balls having a larger pitch circle diameter are disposed between inner and outer rings of the double row angular contact ball bearing at a region near to the pinion gear, and a second row of balls having a smaller pitch circle diameter are disposed between the inner and outer rings at a region remote from the pinion gear. A bearing internal space is divided into a first bearing internal space containing the first ball row and open toward the pinion gear and a second bearing internal space containing the second ball row and sealed by partition walls formed respectively by bearing seals, lubricating grease being sealed in the second bearing internal space.

    摘要: To provide a oblique contact double ball bearing and a pre-load adding method for the ball bearing capable of easily adding the pre-load by performing adjustment for adding the pre-load in a wide adjustment range. In this oblique contact double ball bearing, clearance between balls and raceways and on one row are made different from clearances between balls and raceways on the other row so as to apply a thrust load to inner and outer rings, and the pre-load to the inner and outer rings.

    摘要: There are provided tapered roller bearings which support a pinion shaft. Inner races have large rib faces each having a recessed surface shape on which large-diameter end faces of tapered rollers slide. The surface roughness of the large-diameter end face is σ1 [μmRa] is 0.025 or more. In addition, assuming the surface roughness of the large rib face is σ2 [μmRa], (σ12+σ22)1/2 is 0.17 [μmRa] or less. The sliding portion of the large-diameter end face and the sliding portion of the large rib face are made of a carburized steel, and the carbon content in a matrix phase in a surface layer portion of each of the sliding portions to a depth of 50 μm from a surface is 0.8 wt % or more, the surface hardness thereof is in the range of Rockwell C63 to 67, and a surface retained austenite amount is set to be 20% or more and 25% or less.
