摘要： Provided is a method of manufacturing a resin retainer having two annular sections. A fixed-side cavity forming mold has a first axial mold surface that is in contact with an axial end surface of a first annular section of the annular sections of a resin retainer having two annular sections, and a first protruding portion protruding from the first axial mold surface. A movable-side cavity forming mold has a second axial mold surface that is in contact with an axial end surface of a second annular section of the annular sections of the resin retainer, and a second protruding portion protruding from the second axial mold surface. A slide core sliding step is performed in which slide cores are slid toward an outer diameter and pocket-forming protruding portions of the slide cores are extracted from a pocket of the retainer, and then a mold opening step is performed in which the movable-side cavity forming mold is opened relative to the fixed-side cavity forming mold.

摘要： A thrust bearing includes: a retainer that is provided with a plurality of pockets; a plurality of rollers that are arranged so as to freely rotate inside the plurality of pockets; and at least one first race that has an annular-shaped first race section in which the plurality of rollers move. The first race is provided with a hook curl section that is formed by bending the first race section from an outer-diameter-side periphery thereof toward the inner-diameter side obliquely in the radial direction, and an outer peripheral surface of the retainer has a conical surface that is formed so as to be substantially parallel to an inner peripheral surface of the hook curl section. The inner peripheral surface of the hook curl section holds the retainer without separating therefrom by contacting the outer peripheral surface of the retainer in a sliding manner.

摘要： A rolling-element bearing includes inner and outer rings, a cage with pockets disposed therebetween, and rolling elements respectively retained in the pockets. The cage has a guiding section extending along the axial length of the rolling elements. The distance between a radially-inner surface of the guiding section and the rotational axis of the bearing progressively decreases at least in sections along the axial direction of the rolling-element bearing from a point of the guiding section that is most distant from the rotational axis. A conveying section of the cage connects to that most-distant point and extends outside or away from the axial length of the rolling elements. The distance between a radially-inner surface of the conveying section and the rotational axis progressively decreases at least in sections in the axial direction away from the rolling elements. A lubricant collection channel is defined between the guiding section and the conveying section.

摘要： A cage 7b for a radial roller bearing is achieved that can be manufactured by axial draw molding, and in which end sections 12c that are provided on both sides of a non-continuous section 11a fit together so that relative displacement in the radial direction is possible, and so that relative displacement in the axial direction is not possible. A fitting section 13a where the end sections 12c, 12d fit together comprises an inside fitting piece 17 that is provided in the middle section in the axial direction of one end section 12c, and a pair of outside fitting pieces 18a, 18b that are provided in separated portions on both sides in the axial direction of the other end section 12d so as to not overlap each other with regard to the axial direction. When assembled in a radial roller bearing, by placing the inside fitting piece 17 in the portion between the outside fitting pieces 18a, 18b, the inside fitting piece 17 fits with the outside fitting pieces 18a, 18b in the axial direction without the fitting piece and the outside fitting pieces 18a, 18b overlapping in the radial direction.

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.
摘要翻译：本发明的目的是防止磨损粉末积聚和堆积在滚子轴承的保持器中的凹穴中，从而保护滚子免受滚珠磨损和润滑损失，延长滚子轴承的使用寿命。在保持器的环状区域的内径面上，从保持器的轴向外侧端面向内侧形成切口。切口具有比保持器的内侧突起的外直径端更靠径向外侧位置的外直径位置。这改善了润滑油从保持器的内径侧到形成在环形区域中的切口的轴向流动，使得不太可能在润滑油中包含的诸如金属磨损粉末的灰尘将停留在内侧柱的投影。
