摘要： A rotary drill bit having a drill bit body and at least one trunnion projecting from the drill bit body and a rotary cutter supported on at least one pair of radial rolling bearings on the trunnion. The rolling elements of at least one bearing are guided on at last one axial end facing the drill bit body in an outer bearing race groove incorporated in the bore of the rotary cutter. The inner bearing groove is formed on the trunnion for the rolling elements of the radial roller bearing. A filling opening is provided for assembly of the rolling elements comprising a channel which extends through the drill bit body and trunnion and is essentially axially oriented having one terminal end adjacent the inner bearing race groove and at least one filler piece for sealing the opening. The filling opening is arranged to provide a common filling means for each radial bearing.

摘要： A ball bearing for linear movement on a shaft has a cage with oval guideways, and an outer sleeve surrounding the case. The cage has axially extending raceways for guiding loaded balls, the ends of the raceways joining radially outwardly directed transitions. The transitions are weakened by transversely extending grooves or slots, to provide resilience. The raceways may be axially extending radially inwardly directed ridges having central axially extending grooves, and the transitions may have V-shaped recesses with their apices at the ends of the grooves, to define two-point contact with the balls in the transition area of the bearing. A split sleeve may surround the outer sleeve for additional support.

摘要： A system for continuous lubrication of bearings in a drilling apparatus including a roller bit having at least one pivot and a cutting roller rotatably supported on the pivot by bearings. The system comprises pumping means in the form of spiral or oblique grooves on one of the spaced confronting faces of the roller bit and cutting roller and a flow opening or port arranged to effect flow of a flushing liquid through the bearing upon rotations of the cutting roller. The grooves may be selectively oriented to pump flushing liquid through the annular gap between the roller bit and cutting roller faces radially inwardly or radially outwardly for a given direction of rotation of the cutting roller.

摘要： A clutch release bearing for use with a friction clutch for automotive vehicles having a ring-shaped spring release member. The clutch release bearing is formed as an anti-friction bearing wherein one of its race members has a portion extending axially away from the rolling bodies. The extending portion projects a distance sufficient to be inserted within the bore of the spring release member and to pass behind the rear wall and engage therewith. The race members of the bearing are made of sheet metal and are folded to provide substantially radial walls adapted to engage the front face of the spring release member or the clutch release actuating member. The projection of the one race member may be cylindrical or it may project as a ring-shaped body having slots forming resilient fingers interengaging with the arms of the spring release member.

摘要： An axially movable ball bearing includes a cage having a plurality of circumferentially distributed guideways, each guideway including first and second axially extending channels joined at their ends by semi-circular sections. A plurality of balls are provided in each of the guideways. The first channels are open radially inwardly so that the balls therein may engage a shaft along which the bearing is adapted to move. A thin-walled metal housing is tightly fitted over the cage, and has bridge sections aligned with the first channels. The bridge sections have on their radially inner surfaces, guide courses for engaging the balls in the first channels. The housing is slotted between the bridge sections, so that the second channels project radially outwardly between the bridge sections. The bridge sections are joined together at each axial end of the bearing by end rings. The metal housing has a greater hardness in the region of the courses of the bridge sections than in the other regions thereof.
