    摘要： A rolling bearing assembly in which the number of components is reduced, and a high speed operation can be enabled with an increase of the stirring resistance being avoided by a sufficient discharge of lubricant oil and with an increase of temperature within the bearing assembly being suppressed. The rolling bearing assembly includes a pair of raceway rings, which are inner and outer rings, a plurality of rolling elements interposed between the inner and outer rings and a retailer for retaining the rolling elements. Each of the inner and outer rings is provided with an axially extending raceway ring extension portion and an oil supply and drainage mechanism for supplying a lubricant oil, which concurrently serves as a bearing cooling medium, to the bearing assembly and for discharging the lubricant oil to outside of the bearing assembly is provided in the raceway ring extension portion.

    摘要： A cage of a cylindrical roller bearing includes an annular section, a plurality of pillars that extend axially in an integrated, continuous manner from the inside surface of the annular section, and a plurality of pockets, which are formed between the inner circumferential direction side faces of adjacent pillars, and hold the cylindrical rollers in a freely rotatable manner. The circumferential direction side faces of the pillars incorporate a circular arc surface formed in both the inside and outside diameter directions from the pocket PCD which passes through the pocket center of the pocket, and a roll-off section (lubricant reservoir) provided at the tip end inner circumferential section.

    摘要： An object is to exert the intended fretting-preventive effect without being influenced by the size of variation in rotation (variation in speed) or the size of vibration. An arrangement comprising a main shaft gear 1 having a raceway surface 1c on its inner peripheral surface, a bearing inner ring 2 having a raceway surface 2a on the outer periphery, tapered rollers 3 disposed between the raceway surface 1c of the main shaft gear 1 and the raceway surface 2a of the bearing inner ring 2 and held at predetermined circumferential intervals by a cage 4, an imbalance means which produces a circumferential weight imbalance in the assembly of the tapered rollers 3 and cage 4, wherein the roughness of the cone back face 2b of the bearing inner ring 2 is 0.01-0.04 &mgr;mRa, and the roughness of the large end faces 3b of the tapered rollers 3 is 0.01-0.05 &mgr;mRa, and the radius of the large end faces 3b are worked such that the maximum value thereof including the working precision is substantially equal to the reference radius. Further, full crowning is applied to the rolling contact surfaces 3a of the tapered rollers 3 and the surfaces of the tapered rollers 3 are formed with coating films of the MoS2 type.
