摘要： A system for lubricating bearings in a drilling apparatus including a roller bit with at least one pivot and a cutting roller rotatably supported on the pivot by bearings. A cavity or chamber is formed in the roller bit for a non-compressible flushing liquid. The flow channel which communicates with the chamber at one end and the bearing cavity at the other end, provides a flow path for the flushing liquid to the bearing cavity. In one form the flushing liquid discharges to the bearing cavity at a point remote from an annular gap between the outer axial end face of the cutting roller and the roller bit. In another embodiment circumferentially spaced discharge ports are located between the bearings so that a portion of the flushing liquid is discharged to the environment and the remainder flows through the bearings and out the annular gap.

摘要： 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.

A plurality of radially inwardly directed axially extending projections in the bore form races for rolling elements under load, and surfaces between the projections serve as return races. A cage within the bore has a plurality of axially extending guide channels, and semicircular guide channels interconnect pairs of the guide channels to form endless channels for the rolling elements. The outer housing has inclined surfaces joining the corresponding races for loaded and unloaded rolling elements, whereby the inclined surfaces steplessly interconnect the respective races and extend radially outwardly from each of these races.
