    Abstract: The races of tapered roller bearing, that is the cone and cup of such a bearing, are composite in construction, each including a sheet metal shell form and a core that is cast within the shell form for rigidifying it. Each shell form has spaced apart walls, one of which is tapered and forms a raceway and the other of which is cylindrical. In addition each shell form has an end wall at which the two spaced apart walls are joined. The walls define a cavity that opens out of the shell form at the end opposite from the end wall. The core is within the cavity where it is bonded to the sheet metal walls. While the metal of the shell form may be high alloy vacuum melt steel, the metal of the core may be less expensive. In the production of the races, the shell form serves as a mold for holding the molten core metal as that metal cools and solidifies.

    Abstract: An intermediate thrust bearing is positioned between the rotating cutters and its bearing pin of an earth-boring bit. The intermediate bearing is so configured to take outthrust loads, without rotation, that are directed axially against a radially disposed surface of the roller cone journal as the rock bit works in a borehole.

    Abstract: A journaled bearing assembly including a pair of semicircular half shells defining a sleeve bearing with an outer surface and an inner bearing surface with the surfaces extending axially between laterally spaced opposite ends and circumferentially between oppositely disposed parting faces with the bearing surface being concave and the outer surface being convex axially between the ends while in the free state and held at gage diameter. In the free state the terminal portions adjacent the parting faces are on a longer radius than the radius of the central portion. When held at gage diameter the terminal portions are on a radius equal to the radius of the central portion. The bearing sleeve is disposed in a bearing housing with the bearing surfaces in engagement with a journaled portion of a shaft. The bearing housing includes clamping members in clamping engagement with the outer surfaces of the half shells to apply radical forces to the half shells. These force the concave and convex surfaces into a substantially straight configuration axially between the ends thereof so that the stresses in the half shells are greatest along the circumferential center line and continuously decrease from the center line to the circumferential ends. This stress distribution causes the seating pressure between the bearing sleeve and the housing to be greatest along the circumferential center line of the outer surface of the bearing sleeve and continuously decrease to the portions of the outer surface adjacent the circumferential ends. The resulting pressure gradient allows any oil between the outer cylinderical surface of the bearing sleeve and the housing to follow the path of least resistance and flow from the circumferential center line out the ends from between the bearing sleeve and the housing. Thus, the protective coatings on the outer surface of the bearing which wears free and any build-up of oil oxides will be reduced by being continuously flushed out the ends of the bearing sleeve.

    Abstract: A bearing structure for supporting a shaft in a body is disclosed in which a floating bush is fitted over the shaft and the bush is supported in a cylindrical bearing which is fitted fixedly in the body. Lubricant is supplied to the outside of the cylindrical bearing to a clearance between it and the body, and flows through passages in the bearing to a clearance between the bearing and the bush, where it flows through passages in the bush to the clearance between the bush and the shaft. The passages in the bush are radial, whereas the passages in the bearing are preferably inclined at about 45.degree. to the radii, and extend outward in the opposite direction to the normal direction of rotation of the shaft. The number n of passages in the bush is larger than the number m of passages in the bearing; both of these numbers are even; and the angle subtended at the central axis of the shaft by the opening at the inner end of the passages in the bearing is approximately 360.degree./m-360.degree./n.

    Abstract: A retaining ring (30) includes a cone-shaped, resilient rim (32) which defines a Belleville-type spring. A plurality of resilient teeth (36) extend radially inwardly or radially outwardly from one of the inner or outer edges of the rim, respectively. The retaining ring is receivable onto a shaft or into a housing bore where the resilient teeth (36) engage an annular groove (28) to retain the ring. The Belleville-type spring portion of the retaining ring provides a continuous axial force and allows for the resilient take-up of manufacturing tolerances in assemblies employing the retaining ring.

    Abstract: A thrust bearing or tapered-land thrust bearing including a plurality of lubricant feeding nozzle holes. At least one of the nozzle holes is disposed in close proximity to the leading edge of a tapered surface of a bearing surface of the thrust bearing. By this arrangement, hot oil carryover can be minimized and the temperatures of a film of lubricant formed between the bearing surface and a thrust collar positioned there-against and a bearing body of the thrust bearing can be reduced. Thus the thrust bearing can withstand uses under high speed and high load conditions.

    Abstract: A structural arrangement to restrain skewing of the individual cylindrical rollers which comprise a roller type bearing. At least one of the inner and outer bearing race defining means includes a pair of laterally spaced apart side flanges to partially capture the rollers therebetween with the opposed roller ends each associated with one of the side flanges. At least one of the side flanges is defined by a separate flange member which is selectively movable toward and away from the other side flange. This flange member is urged into engagement with the roller ends associated therewith and causes the rollers to be axially moved so that the roller other ends engage the other side flange. This relationship effects close maintenance of the rollers between the side flanges to prevent roller skewing during bearing use. The means for urging the flange member may advantageously comprise resilient or spring type biasing means as well as fluid pressure. During bearing use, a hydrodynamic lubricant film provides axial pressure to slightly deflect the biasing means and thus accommodate slight separation between the side flanges and roller ends to preclude wear therebetween.
