    摘要: In a clutch release device, a clutch release lever engages one ring of a clutch release bearing, and the bearing ring and release lever are formed to inhibit relative rotation therebetween. For this purpose, the bearing ring may have a polygonal outer surface, in which case the release lever may have parallel flanges between which opposite parallel surfaces of the polygonal section of the bearing ring may be inserted. Alternatively, the release lever may have a wedge shaped portion adapted to engage a braking surface of the bearing ring, formed of a plastic material. In a further modification, the bearing rings have grooves or corrugations in a radially extending surface and adapted to be engaged by one or more projections on the clutch release lever.

    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 rolling bearing for lengthwise movement along a shaft comprised of an outer sleeve having a plurality of races therein for rolling bearings, a cage being provided to guide the rolling bearings. A sealing ring is provided at each end of the assembly, the sealing ring having lips extending radially inwardly to contact the shaft. The sealing lips are thin and elastically bendable, and are mounted to enable bowing thereof into free spaces on opposite sides thereof, depending upon direction of lengthwise movement of the shaft. As a consequence, for small movements of the shaft, the sealing lips cling to the shaft and become bulged, rather than sliding along the shaft.
