Zusammenfassung:	FIELD: well drilling equipment, particularly downhole motors. ^ SUBSTANCE: turbine screw downhole motor comprises gyrator mechanism, which acts in three dimensions, turbodrill and collar connected to turbodrill body and provided with elastic lining. The lining is connected to inner surface thereof and adapted to receive gyrator mechanism. Stator of gyrator mechanism is connected to shaft of turbine turbodrill section by means of tapered splined joint. The tapered splined joint comprises coupling and half-coupling and is connected to shaft of turbine turbodrill section. Rotor cooperating with stator is connected to upper motor sub through flexible member. ^ EFFECT: increased drilling efficiency, reliability and service life. ^ 4 dwg
