摘要： A roller bearing cage is disclosed, which is provided inexpensively from basic minimum quantity of row material. The roller bearing cage is made with a production method using rolling operations, which is the absence of the formation of chips, while ensuring the strength and stiffness of the cage. A circular inside surface of the cage is made to give an advantage to the rolling operations. The circular inside surface is circularly recessed to have a concaved surface of just one radius of curvature R. A diametral dimension across diametrically opposing bottoms of the circular recess is made larger than the pitch circle distance P.C.D. Pillars of the cage have inside retainer lips, which are hard to make any engagement with their associated rollers, which might worsen the engine performance.

摘要： Firstly, a roller and cage assembly is disclosed that achieves improved lubricating property while maintaining or increasing rigidity. While concave portions are formed so as to extend the width of the central portion of pockets to allow these to act as oil grooves, on the other hand, padding equivalent to lightening holes that are removed by providing said concave portions is performed in columns to obtain high rigidity.Secondly, a roller and cage assembly is disclosed that together with being inexpensive and having high wear resistance, suppresses the generation of heat resulting from high-speed rotation. The above-mentioned effects are obtained by forming a composite plated film at prescribed sites by uniform dispersed coprecipitation of fine particles of fluororesin.Thirdly, a roller and cage assembly is disclosed that together with suppressing the generation of heat resulting from high-speed rotation, also achieves light weight. The above-mentioned effects are obtained by using ceramic rollers.

摘要： A roller bearing cage is disclosed in which a pair of semicircular cage halves is assembled with their mating ends thereof coming into abutment against each other. The mating ends are chamfered off to stave off bearing failure resulting from any deformation that might occur at the areas nearby the mating ends owing to large centrifugal force imposed by high-speed engines. The roller bearing cage may be completed by only joining together the semicircular cage halves with their diametral mating ends coming into engagement with one another. Each of the semicircular cage halves is composed of axially opposing semicircular rims and cage bars interposed between the rims, thus helping ensure stiffness with even weighing less. The chamfering operation is done to make even any outer peripheral areas nearby the mating ends, preparatory to cutoff operation to split a cylindrical cage stock into two halves. This helps the process management of material-removal work to make the chamfered even areas.

摘要： A roller bearing cage having load capacity large enough to bear severe conditions imposed by high-speed engines, with even lighter in weight. In the roller bearing cage, the cage bars are each made up of axially opposite thick ends and a slim mid-area lying midway the thick ends to define a recess between them. The cage bar has radially outside projections on an outside periphery thereof while radially inside projections on an inside periphery thereof to keep the rollers against escape out of the cage. The radially inside projections extend circumferentially of the cage, especially, at a circular edge of the thick end, which lies nearby or neighboring or closer to the recess. The radially inside projections are made by forcing material at the edge to move circumferentially by plastic flow into the projections that extend circumferentially towards pockets on a radially inside circular surface of the thick end.
摘要翻译：一种滚子轴承保持架，其承载能力足以承受高速发动机施加的严重条件，重量更轻。在滚子轴承保持架中，保持杆各自由轴向相对的较厚端部和位于较厚端部的中间的细长中间部分构成，以在它们之间形成凹部。笼杆在其外周边上具有径向外侧的突出部，同时在其内周的径向内侧突出部分，以防止滚子从保持架中脱出。径向内侧的突起在保持架的周向延伸，特别是在位于附近或邻近或更靠近凹部的厚端的圆形边缘处。径向内部的突出部分是通过在边缘处强迫材料通过塑性流沿周向移动到沿圆周方向延伸到厚端部的径向内部圆形表面上的凹穴的突起中制成的。

摘要： A ball-stud joint having a flange on a stud thereof, the flange having a sloping side for making it easy to locate centrally the stud relatively to a lower die jig. The ball stud is comprised of a ball fit for pivoting movement into a major body, a stud having a plain end adapted to be formed into a rivet head to joint the stud with any counterpart, and a flange formed integrally around the stud to provide a surface coming into abutment against the counterpart. The flange has a sloping side extending radially outwardly from a flat surface facing on to the ball to an outside periphery of the flange in such a way that the sloping side comes into engagement with a slantwise bearing area on a lower die jig when the plain end of the stud is formed into rivet head.

摘要： A linear motion rolling contact bearing assembly includes a trough-shaped bed, a trough-shaped table which straddles the bed, a plurality of balls interposed between the table and the bed for providing a relative motion between the table and the bed along the longitudinal direction of the assembly, and a retainer for retaining the balls in position. The retainer includes an elongated plate provided with a plurality of holding holes for holding the balls in position and at least one side projection which projects sideways from the plate so as to maintain the retainer in its intended position. Preferably, the top and bottom side projections are provided on both sides of the plate so that the retainer has an I-shaped cross section. The retainer is also preferably provided with one or more tabs provided around each of the holding holes so as to securely hold the balls in position. The side projections may be provided also in the form of a plurality of dots.
