    摘要: An object of the present invention is to prevent abrasion powder from accumulating and stacking in pockets in a retainer of a roller bearing, thereby protecting the rollers from brinelling and loss of lubrication for extended life of the roller bearing. On an inner diameter surface of annular regions in the retainer, cutouts are formed from the retainer's axially outer side end surface toward an inner side. The cutout has an outer diametrical position on a more radially outer position than an outer diametrical end of the inner-side projection of the retainer. This improves an axial flow of lubricant oil from an inner diameter side of the retainer toward the cutout which is formed in the annular region, making it less likely that dust such as metal abrasion powder contained in the lubricant oil will stay at the inner-side projection of the pillar.

    摘要: A retainer includes two annular retaining plates combined with each other, and each having semispherical bulging portions arranged at predetermined intervals along a circumferential direction of the retainer. The semispherical bulging portions, which face each other, form a pocket having a ring-like shape, for retaining a ball. The pocket includes a ball non-contact portion formed in a ball facing surface of the pocket at a center portion in a pocket axial direction, the ball non-contact portion being defined by a recess extending in a pocket circumferential direction. The following relationship is set: A/(B+C)=0.70 to 0.90, where “A” represents a pocket circumferential length of the ball non-contact portion, “B” represents a diameter of the ball, and “C” represents a gap formed between the ball and the ball facing surface of the pocket.

    摘要: A porous compact impregnated with lubricant fits into an end cap in a fashion exposed in part to a turnaround passage to apply the lubricant around balls while the balls roll through the turnaround passage. The porous compact is placed in a concavity in an end cap major part and a slot rounded at opposite ends thereof is formed in an outside curved portion of the turnaround passage to communicate the concavity with the turnaround passage. An applicator nose of the porous compact is exposed to the turnaround passage through the slot. The balls while being guided along edges of the slot come into rolling-contact with the exposed surface of the porous compact to be coated with the lubricant.

    摘要: A rolling bearing includes an inner ring, an outer ring, and a plurality of rolling elements. A large number of inside dimples in which a liquid lubricant is retained and a large number of outside dimples in which a solid lubricant is retained are formed in at least one of an inner ring raceway surface and an outer ring raceway surface. The inside dimples are formed in a contact region at which the raceway surface contact the rolling elements or in a section of each non-contact region, the section being close to the contact region. The outside dimples are formed outside a portion in which the inside dimples are formed.

    摘要: A structure (200) for containing a volume of lubricant additive gel (10) which is disposed within a mechanical system, in close proximity to a wear critical surface, and which is configured to provide a release of the contained additives into a flow of lubricant over time or as a function of temperature in a site-specific manner to minimize wear or reduce oil oxidation due to harsh operating conditions. The structure defines a cage or capsule with screen or mesh sides (202) having multiple perforations or openings through which the flow of lubricant may circulate. Within the contained volume of the structure (200), additives are disposed in a gel matrix (10), and are release over time or as a function of temperature, through the perorations or openings, in close operative proximity to wear critical surfaces of the mechanical system such as a bearing assembly or gear arrangement.
