Abstract: 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.

Abstract: A sliding thrust bearing has one bearing surface separated into a plurality of regions, each of which has a slot extending radially from the circumferential edge thereof. A plurality of grooves extends from each of the opposite sides of the slot, the grooves extending from opposite sides of the slot being inclined in opposite directions with respect to the circumferential direction of the bearing surface. A further bearing surface engages the grooved surface, whereby pressure of a lubricant builds up in the groove to one side of the slot for one direction of relative rotation of the bearing surfaces, and pressure of the lubricant builds up in a groove to the other side of the slot for the opposite direction of relative rotation of the bearing surfaces. The bearing surfaces may be flat or curved.

Abstract: An articulated bearing has an inner ring with a spherical outer surface, and an outer ring with a hollow spherical inner surface corresponding to and engaging the outer surface of the inner ring. Plastic bearing segments are circumferentially arranged in the cylindrical bore of the inner ring. The plastic segments are held by rings having inclined ends engaging the ends of the plastic segments. Circumferential displacement of the segments is prevented by strips affixed in the bore of the inner ring between adjacent segments. The plastic segments extend radially inwardly of the holding rings and strips a distance, in the absence of loading of the bearing, corresponding to the elastic deformation of the segments in the loaded condition. A pin in one of the inner and outer rings is urged into a recess in the other of the inner and outer rings, by means of a spring.

Abstract: A fluid bearing system for journalling a rotatable shaft in which an annular housing is fixed about the shaft and is provided with an inlet for the supply of fluid under pressure. At least one bearing compression chamber is formed in the housing and/or the shaft and is distributed about the periphery of the shaft. The housing and the shaft form an integrated throttle control means in which a restrictor opening and a discharge opening is formed between the housing and the shaft for the flow through of fluid from the inlet. The openings are simultaneously varied relative to each other in an opposing manner as a function of the size and distribution of the load placed on the shaft.

Abstract: A loading aperture is provided in the circumference of the race of a rolling bearing for the insertion of rolling members into the race, and an expandable closure is provided for closing the aperture.

Abstract: In a bearing assembly for a roll the journal of the roll is supported radially by roller bearings mounted in a stationary support structure. The thrust bearing for the assembly includes a pair of outer rings mounted co-axially at the end of the journal, and a central ring therebetween and supported by the support structure. The rings define a pair of races for tapered roller bearings. The surfaces of the central disk extend normal to the axis of the journal. A support for the central ring includes a bolt co-axial with the journal and extending into a recess at the end of the journal. Apertures are provided in the structure to permit the flow of cooling air at the end of the assembly.

The centering ring, which is fastened to the nonrotating bearing race, is fastened to the sliding sleeve by at least one clamp which surrounds a radial flange of the sliding sleeve, or of the centering ring, with radial play.

Abstract: Bearing materials having low coefficient of friction and high wear resistance comprise 50 to 90 percent by weight of a powdered solid lubricant bonded by a polymerized mixture of unsaturated organic compounds, containing at least 30% divinylbenzene. The solid lubricant is preferably MoS.sub.2 or a mixture of MoS.sub.2 and graphite. The binder is preferably polymerized technical divinylbenzene, a mixture of isomers.

Abstract: A method for forming an arcuate electrode adapted for the electrolytic production of grooves in the arcuate surface of an article, in which grooves are first formed in a plane metal blank. The grooved blank is then reshaped to have a curvature corresponding to that of the article, and the grooved curved surface of the blank is coated with an insulating material. The insulating material is then removed from the surface of the blank, except in those areas overlying the grooves, and the thus bared portion of the blank is then eroded, for example, by etching, so that the residual insulating layer projects from the surface of the blank. In use, the thus formed electrode is employed as a cathode, with the projecting insulation being held in close contact with a corresponding curved surface of the article to be grooved. The article is connected as an anode, and an electrolytic liquid is directed to flow in the channels formed between the electrode and the article.
