FIELD: mining.SUBSTANCE: group of inventions relates to applied equipment and performed operations, connected to underground well construction, and provides use of equal angular velocities connecting assembly for drill string. Equal angular velocities connecting assembly for drill string during torque transfer between downhole motor and drilling bit includes at least one ball joint. At that, ball joint additionally contains second axis, perpendicular to first axis, and insert. Insert has shape, which enables its rotation around transverse axis, perpendicular to hole transversely passing through ball joint. Ball joint seat is made with possibility of rotation and about ball joint second axis with adjustment to planetary or epicyclic rotor movement in bottom-hole motor.EFFECT: higher reliability of rotation and torque transmitting between downhole motor and drilling bit by equal angular velocities assembly.30 cl, 6 dwg |
