摘要:
Ball bearing assembly for rotatably supporting a belt support roll on an axle comprising a pair of bearing rings having confronting spaced apart sections defining inner and outer raceways disposed at an angle to the normal axis for a plurality of balls. The inner bearing ring has a radial outwardly directed flange serving as means to secure the bearing to the roll casing and a flange extending radially inwardly from the race confronting a sleeve mounted on the axle. The outer bearing ring has an annular ring flange facing inwardly to the bearing axle confronting the radial flange of the inner bearing ring and terminating in an annular shoulder running axially for fastening to the axle. A sleeve circumscribes the axle and has a radially outwardly directed rib which forms with the inner bearing ring an annular chamber for a sealing agent. A seal with flocked fibers is interposed between the confronting inner flanges of the inner and outer bearing rings.

A cage for ball bearings consists of two side rings connected together by webs, and having ball pockets with ball pockets having curved partial surfaces inside and outside of the pitch circle and displaced from one another in the axial direction. In this arrangement the rubbing between the walls of the cage pockets and the balls is very small and free space is provided for receiving a lubricant. The pocket walls of the cage sections lying in the region of one or the other of the side rings has several radially-overlying zones, with conical surfaces, the conical surfaces being arranged at different inclinations to the bearing axis.

A ball bearing has an inner ring and an outer ring defining inner and outer races respectively. A row of balls is provided between the races, and a cage holds the balls spaced apart from one another. The compartments of the cage are staggered alternately, so that adjacent balls engage opposite regions of the races to inhibit axial play.
摘要:
A self-centering clutch thrust bearing with a resilient ring between the bore of the bearing and a sliding sleeve for damping radial play therebetween.
摘要:
An improved self-centering clutch thrust bearing is described which includes a rolling bearing assembly and a sleeve bearing. The sleeve bearing and rolling bearing assembly each include radially extending flanges and means are provided for captivating the flanges in an axial direction while allowing limited play in a radial direction. An annular collar and an annular disc are also provided and are positioned for enabling a limited relative motion in a radial direction between the bearing assembly and the sleeve bearing.

A thrust ball bearing has an outer cup-shaped ring and an inner cup-shaped ring. A ball bearing assembly of a plurality of balls and a cage is arranged between the closed ends of the bearing rings. The closed bottom of the outer ring is curved, with the center of curvature being on the side thereof toward the bearing assembly. The bearing rings have thin walls, and the thrust ball bearing is particularly adaptable for use as a clutch throw-out bearing.

In a rolling bearing for linear movement with respect to a shaft, the bearing has a sleeve, and axially extending guide rails on the inner and outer surfaces of the sleeve. Rolling elements are guided by the guide rails, and have concave spool-like central portions matched to the shaft, to provide linear contact therewith. The ends of the rolling elements are convexly curved to match the curvature of the inner surface of the sleeve, so that the inner surface of the sleeve forms a raceway for rolling elements under load. Grooves are provided in the lateral surfaces of the guide rails for guiding balls disposed between the ends of adjacent rolling elements. End caps on the bearing have turn-around guides for directing rolling elements between the inner raceways and the raceways for unloaded rolling elements along the outer surfaces of the sleeve.

A clutch release device for use with a thrust bearing has a sliding sleeve formed as a cylinder with a flange extending radially outward, and a transition shoulder between the cylinder and flange; a radially extending reference plane extends through said shoulder, and said flange has portions thereof displaced axially, with said reference plane being equidistant from said flange and said displaced portions.

A siding collar is provided for a fork-activated coupling clutch release bearing, including a collar body with a cast-in wear-resistant disc formed on a radial flange. A plurality of contact zones on one side of the disc contact the fork. On the bearing side of the disc the nonrotating bearing ring contacts the disc, the disc having a plurality of guide zones running essentially axially along the edge, with means for securing this bearing ring to the collar having guide zones for holding this bearing ring on the sliding collar against rotation on the sliding collar.

In a rolling bearing for longitudinal movement with respect to a shaft, the rolling elements have longitudinal cross sections with concave central sections adapted to engage a cylindrical machine element, and shaped ends adapted to roll on a support surface of the machine element. The bearing includes a shell structure for guiding the rolling elements to follow continuous pathways. Each pair of adjacent rolling elements are separated from contact with one another by a separating roller having a convex longitudinal cross section which engages the concave portions of the rolling elements with line contact.
