摘要： A rolling bearing assembly for lengthwise movement with respect to a shaft has an outer sleeve with internal races, and a cage guiding endless rows of rolling bodies in the bore of the outer sleeve. The cage has a slit extending axially and radially therethrough, and the cage portion aligned with the slit is radially moveable, so that an entire row of rolling bodies adjacent said slit may be radially moved into a race formed in a shaft in the bearing. The sleeve may have a second slit spaced from the first slit. The second slit may be only partial, to define a region of bending, or may extend completely through the outer sleeve to define a segment, with the first slit, that is radially moveable.

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 linear rolling bearing has an outer housing with a central bore. 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.

摘要： In a longitudinally movable rolling bearing having a plurality of endless rows of spherical rolling elements, elongated races are provided for supporting loaded rolling elements against the inner boring of a housing. The radially directed surfaces of the rails are identical, so that the rails may be reversed to prolong the life of the bearing. In one embodiment, the rails are straight in the lengthwise direction, for use in a bearing in a precision machine. In another embodiment of the invention, the rails are convex curved in the lengthwise direction, for use in a bearing requiring compensation for misalignment of a shaft and the housing.
