    摘要： An earth boring bit has a bit body with a depending bearing pin. An insert ring is mounted on the bearing pin. The insert ring has an inner diameter greater than an outer diameter of the bearing pin, defining a clearance between the insert ring and the bearing pin to allow the insert ring to float relative to an axis of the bearing pin. An inner seal is in sealing engagement with the bearing pin and the inner diameter of the insert ring. A cone is rotatably mounted on the bearing pin, the cone having a cavity containing an outer seal groove. An outer seal located in the outer seal groove is in dynamic sealing engagement with an outer diameter of the insert ring. An anti-rotation member engages a portion of the insert ring to prevent rotation of the insert ring.

    摘要： A rotary drill bit for drilling subterranean formations configured with at least one protective structure proximate to the rotationally leading and trailing edges of a gage trimmer, wherein the at least one protective structure is positioned at substantially the same exposure as its associated gage trimmer. Particularly, the apparatus of the present invention may provide protection for gage trimmers during drilling, tripping, and/or rotation within a casing; i.e., when changing a drilling fluid. Protective structures may be configured and located according to anticipated drilling conditions including helix angles. In addition, a protective structure may be proximate to more than one gage trimmer while having a substantially equal exposure to each associated gage trimmer. Methods of use and a method of rotary bit design are also disclosed.

    摘要： An array of chisel-shaped cutting elements are mounted to the face of a fixed cutter bit. Each cutting element has a crest and an axis which is inclined relative to the borehole bottom. The cutting elements have a hardened diamond exterior on all surfaces in contact with the formation. The chisel-shaped cutting elements may be arranged on a selected portion of the bit, such as the center of the bit, or across the entire cutting surface. In addition, the crest on the cutting elements may be oriented generally parallel or perpendicular to the borehole bottom. The chisel shape and crest orientation increase the initial contact area while reducing aggressiveness. These advantages are achieved without increasing cutter density, reducing back rake, or adding depth of cut limiters. Chisel-shaped cutting elements having crests which are oriented perpendicular to the borehole bottom have the added advantage of displacing the material in a plane that is parallel to the bit face. This reduces the likelihood of harmful bit balling, particularly on heavy set bits with small open face volume.

    摘要翻译： 凿子切割元件阵列安装在固定刀头的表面上。 每个切割元件具有相对于钻孔底部倾斜的波峰和轴。 切割元件在与地层接触的所有表面上具有硬化的金刚石外观。 凿子形切割元件可以布置在钻头的选定部分上，例如钻头的中心，或跨越整个切割表面。 此外，切割元件上的波峰可以大致平行或垂直于钻孔底部定向。 凿子形状和波峰方向增加了初始接触面积，同时降低了攻击性。 这些优点在不增加刀具密度，减少后刀尖或增加切削限制器的深度的情况下实现。 具有垂直于钻孔底部定向的波峰的凿状切割元件具有在平行于钻头面的平面内移动材料的附加优点。 这样可以减少有害钻孔的可能性，特别是在打开面积小的重型钻头上。
