  • Publication number: 20110024199
    Abstract: An elastomeric seal ring is located between each bearing pin and each cone of an earth-boring bit. An auxiliary ring or band is imbedded within an annular recess formed in the inner diameter of the seal ring. A portion of the inner diameter of the seal ring as well as the auxiliary ring are in dynamic contact with the bearing pin. The auxiliary ring has a geometric feature that enhances radial flexibility but prevents it from sealing. The geometric feature may be a transverse cut, notches in either the inner or outer diameters, or holes extending between the sides of the auxiliary ring. The auxiliary ring has lubricating properties.

  • Patent number: 7741561
    Abstract: In combination with a alternating-current-carrying electric power cables and a guide holding the cable. The guide is constructed such that electrical or magnetic radiation emitted by the cable can pass through the guide, an electrosmog shield has a channel formed of a material capable of blocking low-frequency electrical and magnetic radiation and dimensioned to fit with the conduit.

  • Patent number: 7708090
    Abstract: An elastomeric seal ring is located between each bearing pin and each cone of an earth-boring bit. An excluder ring or band is imbedded within the inner diameter of the seal ring. A portion of the inner diameter of the seal ring as well as the excluder ring are in dynamic sealing contact with the bearing pin. The excluder ring may be harder and more wear resistant than the seal ring. The excluder ring may have lubricating properties. An outer excluder ring may be located on the outer diameter of the seal ring for engaging the cone to resist rotation.

  • Publication number: 20080066970
    Abstract: A shank configuration for rotary drill bits, is disclosed for positioning of the shank in relation to the bit body. A tapered surface or feature of the shank may be configured and sized to matingly engage a complementarily shaped surface or feature of the drill bit body and thereby become centered or positioned in relation thereto. A deformable element may be disposed between the shank and bit body. Also, the shank may comprise a material having a carbon equivalent of less than about 0.35%. A multi-pass weld procedure may be employed to affix the shank and bit body to one another wherein welds may be formed so that one weld originates at a circumferential position that differs from the origination circumferential position of its immediately preceding weld by at least about 90°. Further, a stress state may be developed within the multi-pass weld. A method of manufacture is also disclosed.

  • Publication number: 20070014495
    Abstract: A roller cone bit has a ball retention system to secure the cones to the head. A radial ball race includes a ball way with a ball plug to keep the balls in the ball race. The ball plug is secured to the head by welding. Any residual stress in the weld region is alleviated by one of several solutions. Material may be selectively removed from the weld, the heat-affected zone, and/or the surrounding area to promote relaxation of residual stress. Alternatively, deflection is imposed and/or heat or vibration is applied to promote relaxation.
