Patent number: 10253820Abstract: A joint for a BHA includes an inner driven rod, an outer drive coupling, and a thrust plate. The inner driven rod includes at least one lobe extending radially therefrom. The outer drive coupling includes a keyway formed therein corresponding to and adapted to receive each lobe. A thrust plate is positioned between at least one side of each lobe and the corresponding keyway. The thrust plate may allow for the reduction of point or line stress loading on the lobe and keyway.Type: GrantFiled: March 21, 2016Date of Patent: April 9, 2019Assignee: SCIENTIFIC DRILLING INTERNATIONAL, INC.Inventors: Mark Chustz, Jon Meier

Patent number: 9309720Abstract: A drilling apparatus includes a housing that defines a longitudinal axis. A power section of the apparatus includes rotor adapted to move with eccentric rotary motion with respect to the longitudinal axis in response to the passage of drilling fluids through the power section. A power transmission shaft has an upper end coupled to the rotor and movable with the eccentric motion of the rotor, and a lower end constrained to rotate in a concentric manner with respect to the longitudinal axis. A generally rigid torsion rod has upper and lower ends constrained to rotate in a concentric manner, and the upper end of the torsion rod is coupled to the lower end of the power transmission shaft. A mandrel including a connection for a drill bit is interconnected with the lower end of the torsion rod such that a torque may be transmitted from the torsion rod to the mandrel to drive a drill bit.Type: GrantFiled: November 9, 2012Date of Patent: April 12, 2016Assignee: SCIENTIFIC DRILLING INTERNATIONAL, INC.Inventors: Douglas Baugher, Mark Chustz, Joe Rivas

Patent number: 9045941Abstract: A bearing assembly for use in a down-hole drilling apparatus includes a bearing housing configured for connection to a drill string and a mandrel disposed at least partially within the bearing housing. The mandrel is configured to rotate about a longitudinal axis extending therethrough. A hybrid thrust bearing package is provided and disposed radially between the bearing housing and the mandrel. The hybrid thrust bearing package includes a plurality of ball bearings movable through at least one race, an annular stator supported by the bearing housing and an annular rotor ring supported on and rotatable with the mandrel. The annular stator and rotor rings define first and second flat PDC bearing surfaces engaged with one another at a bearing interface oriented generally orthogonally with respect to the longitudinal axis.Type: GrantFiled: October 25, 2012Date of Patent: June 2, 2015Assignee: SCIENTIFIC DRILLING INTERNATIONAL, INC.Inventor: Mark Chustz

Publication number: 20130170778Abstract: A bearing assembly includes a first race having a first set recesses disposed on an upper surface thereof. Wherein a first set of bearing elements are disposed within the first set of recesses and the first set of bearing elements extend upwardly from the first set of recesses at an inclination relative to a vertical axis of the first race. A second race having a second set of recesses disposed on an upper surface thereof. A second set of bearing elements are disposed within the second set of recesses and the second set of bearing elements extend upwardly from the second set of recesses at an inclination relative to a vertical axis of the second race.Type: ApplicationFiled: June 29, 2010Publication date: July 4, 2013Applicant: Scientific Drilling International, Inc.Inventors: James Robbie Higginbotham, Mark Chustz
