Abstract
Methods and apparatus are disclosed for coupling components within a downhole motor drivetrain, and particularly to improving the torque carrying characteristics through threaded couplings in the drivetrain that extends between the mud motor and the drill bit. The described downhole motor drivetrain includes one or more threaded couplings, with each coupling configured to define a gap to accept a spacer having a dimension within a range of sizes. The dimension of the selected spacer placed in the threaded coupling facilitates establishing a desired balance of the force loading at each of two contact regions of the coupling. In many examples, the two contact regions of the coupling will be located on opposite sides of the threaded region.
