摘要： A bearing assembly having an inner race ring (14) that defines an inner raceway and an outer race ring that defines an outer raceway on which the plurality of rolling elements (22) roll. The bearing raceways are machined using surface finishing operations to create preferred surface profiles and textures for improving lubrication performance. The profile of the raceway is initially created using a first grinding process to form a rough surface profile including a rough central band (34) and rough recessed side bands (38). A second grinding process is used to smooth the central band. This raceway surface profile increases lubrication performance.

摘要： A roller bearing includes an inner race ring, an outer race ring, and a roller arranged between and in contact with the inner and outer rings. The bearing has a flange on the inner race ring at one axial end, and a flange on the outer race ring at an opposite axial end. At least one of the flanges, or an end of the roller, has a profile including a principal segment with a reference point C defining a contact location between the roller and the flange, the principal segment having a continuously changing radius of curvature, on both sides of reference point C, that decreases as a distance from the reference point C increases.

摘要： A roller bearing (10) defines a bearing axis (34) and a radial plane (52) oriented parallel with the bearing axis. The roller bearing (10) includes an inner ring (42) having an inner raceway (44) and an inner flange (46) extending from the inner raceway. The inner flange (46) includes an inner guide surface (48). The roller bearing (10) also includes a plurality of rollers (22) in rolling engagement with the inner raceway (44) about the bearing axis (34). Each roller (22) includes a first end surface (24a) in engagement with the inner guide surface (48) of the inner flange (46) as the plurality of rollers (22) move relative to the inner ring (42). The first end surfaces (24a) of each roller (22) define a curvature such that a ratio of a first principal effective curvature (Rx) radius in a plane perpendicular to the radial plane (52) and a second principal curvature radius (Ry) in the radial plane (52) is no less than 3.0.

摘要： A double row thrust bearing assembly (10) includes a bottom plate (11) having inner and outer conical raceways (12, 13), a top plate (14) with a flat raceway (15), and respective sets of identically formed inner and outer rollers (16, 17) mounted on respective inner and outer cages (18, 19). When the bearing is fully assembled, the apices of the inner and outer rollers directed at the same point (A) on an axis (X) of the bearing. Various relationships with respect to the size and shapes of the rollers are determined in order to maximize the bearing assembly's load carrying capacity while occupying the same spatial envelope as that of a single row thrust bearing assembly (BA) which can only support a lesser load.

摘要： A method for heat treating a gear having gear teeth includes removably mounting the gear on a work-piece holder, moving one of either a magnet assembly or the work-piece holder to bring the gear and the magnet assembly into heating proximity, rotating the magnet assembly for a desired amount of time while said magnet assembly and gear are in heating proximity to each other to heat treat surfaces of the gear teeth, moving one of either the magnet assembly or the work-piece holder relative to the other to bring different surfaces of the gear into heating proximity with said magnet assembly, and repeating for each opposed pair of gear teeth surfaces until all said gear teeth surfaces are heat treated.

摘要： A roller bearing includes an inner race ring, an outer race ring, and a roller arranged between and in contact with the inner and outer rings. The bearing has a flange (31,131) on the inner race ring at one axial end, and a flange (21,121) on the outer race ring at an opposite axial end. One of the flanges, and/or an end of the roller, includes at least one principal segment (53,153) intermediate two additional segments (52,152; 54,154). The principle segment is tangentially blended with the two additional segments, and the principle segment has a first curvature that is different from the respective curvatures of the two additional segments. A non-elliptical contact footprint can be obtained by composite profiles at the contact location between the roller end and the mating flange face.

摘要： A dual tip cutter (10) includes a body (12) defining a feed direction (F), a cutting direction (C) perpendicular to the feed direction, and a depth direction (D) perpendicular to both feed and cutting directions. A first cutting portion (35) is fixed relative to the body at a body first end. A second cutting portion (45) is fixed relative to the body at the body first end, adjacent the first cutting portion. The first and second cutting portions are stacked in the cutting direction so that the first cutting portion forms a leading cutting portion and the second cutting portion forms a trailing cutting portion for simultaneous cutting. The second cutting portion extends from the body further in the depth direction than the first cutting portion. A relative position between the first and second cutting portions is set such that a total chip load is shared between the first and second cutting portions in a predetermined ratio (K).
