摘要： A roller bearing having spacers interposed between its rollers is provided, which has a high permissible rotational speed which is achieved by allowing a lubricant to flow smoothly around rolling surfaces so that the stirring resistance of the lubricant due to the spacers is reduced. The roller bearing includes: a plurality of rotatable rollers (16) interposed between an inner ring raceway surface and an outer ring raceway surface; and spacers (18) provided between adjacent rollers (16). Each of the spacers (18) includes extended portions (18a) facing roller end faces (16b) at both axial ends thereof.

摘要： Disclosed herein is a bearing assembly comprising: an outer race having an inner surface; an inner race having an outer surface, the inner surface of the outer race and the outer surface of the inner defining a bearing assembly raceway; a plurality of main rollers positioned within the bearing assembly raceway, the main rollers in contact with the inner surface of the outer race and the outer surface of the inner race; a plurality of mediate rollers positioned within the bearing assembly raceway counter-rotating with the main rollers such that each of the mediate rollers is in rolling contact with a pair of the plurality of main rollers; and a cage positioned in the bearing assembly raceway for at least for at least partially bounding each of the mediate and main rollers. In one embodiment, the cage can be positioned within the bearing assembly raceway and comprises a cage body, the body having a plurality of parallel annular rims joined by a plurality of rungs, the rungs separated so as to define a plurality of main roller openings in the cage body for receiving the plurality of main rollers, the rungs having a plurality of mediate roller retainers extending from the rungs, the retainers permitting counter-rotating of the mediate rollers with the main rollers in the main roller openings. The inventive bearing assembly results in substantial reduction of noise and vibration when compared to conventional bearing assemblies.

摘要： A guide (10) associated with a linear motion and screw system is configured to at least partially surround one of a plurality of rolling elements (20) so as to prevent ball-to-ball contact between the one rolling element and adjacent rolling elements during displacement of the rolling element along a circulation ball track.

摘要： A linear motion guide unit is disclosed in which a separator interposed between any two adjoining rollers fits over or embraces the rollers flanking the separator, thereby realizing low noise and low wear. The separator(4) lying between any two adjoining rollers(3) is made concaved(22) at forward and aft sides thereof to fit snugly over the rollers(3) in rolling-contact relation. The separator(4) is made with a sunken relief(30) on at least an inward side(54) thereof, which is near a radially inside curved surface (29) in the turnaround(11,12), the sunken relief(30) extending lengthwise of the separator(4) and being provided by making the separator(4) reduced in width lest the separator(4) comes in engagement with the radially inside curved surface(29) in the turnaround (11,12). A gutter(30) for relief is cut in the radially inside curved surface(29) in the turnaround (11,12) in a way extending circumferentially along the turnaround(11,12), thereby keeping the separator(4) from coming in any interference with the radially inside curved surface(29) in the turnaround(11,12) when the separator(4) travels through the turnaround(11,12).

摘要： A radial rolling bearing has cylindrical rolling bodies (2) which roll between an inner ring (11) and an outer ring (10). Individual spacers (1) are inserted between every two adjacent rolling bodies (2). The spacers (1) have contact surfaces (4) on both sides of their longitudinal center plane (3) and when the radial rolling bearing rotates, they are guided by means of one of their end sections (4a) on a running track of the inner ring (11) or outer ring (10). The spacer (1) is characterised in that a section (5) of the contact surfaces (4) has a convex, concave or flat profile on both sides of a sector (12) of the radial rolling bearing. When said section (5) is concave, its radius of curvature is substantially larger than the radius of curvature (8) of the rolling body (2). Because of the missing osculation between the spacer (1) and rolling body (2), an improved lubrification is achieved, and because of a defined point of application of force of the rolling body (2) on the spacer (1), the braking effect of the spacer (1) is compensated. Because of the reduced frictional heat, rolling bearings with such spacers can be driven at a very hig maximum speed of rotation.

摘要： A rolling bearing, comprising two bearing rings (10, 11), a number of roller elements (12) arranged between the bearing rings (10, 11) and a retainer (13) for the roller elements (12). The retainer (13) contains several segments (14), whereby a roller element (12) is guided between opposed surfaces (16, 17) on two adjacent segments (14).
