Patent number: 8978786Abstract: An earth boring drill bit designed for a specific performance, within a finished product tolerance, using components built to a looser manufacturing tolerance. The bit may be assembled by selecting a leg from a plurality of pre-manufactured legs; selecting a bit body from a plurality of pre-manufactured bit bodies, the bit body having a slot for receiving the leg; placing the leg within the slot; and fixing the leg within the slot within the finished product tolerance by placing one or more shims between the leg and the slot. The shims may be used to adjust an axial position, a radial position, and/or a circumferential position of the leg with respect to the slot. The leg and the bit body may be selected, or produced, to ensure the bit will not meet the specification, given the manufacturing tolerance, without the shims.Type: GrantFiled: November 4, 2010Date of Patent: March 17, 2015Assignee: Baker Hughes IncorporatedInventors: Don Q. Nguyen, Anton F. Zahradnik, Rudolf C. Pessier, Mark P. Blackman, Robert D. Bradshaw, Scott A. Young, Ronny D. McCormick, Shyam Anandampillai, Michael S. Damschen, Robert J. Buske

Patent number: 7392862Abstract: 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.Type: GrantFiled: August 4, 2006Date of Patent: July 1, 2008Assignee: Baker Hughes IncorporatedInventors: Anton F. Zahradnik, Don Q. Nguyen, Ronny D. McCormick, Terry J. Koltermann, Michael Joseph Veasey

Patent number: 6883623Abstract: 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.Type: GrantFiled: October 9, 2002Date of Patent: April 26, 2005Assignee: Baker Hughes IncorporatedInventors: Ronny D. McCormick, Mumtaz Ball, Mark E. Anderson, Mark W. Dykstra, Michael L. Doster, Matthew R. Isbell

Patent number: 6332503Abstract: 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.Type: GrantFiled: December 15, 1998Date of Patent: December 25, 2001Assignee: Baker Hughes IncorporatedInventors: Rudolf C.
