Abstract
FIELD: well drilling equipment; particularly, turbodrills. SUBSTANCE: axial bearing and seal mounted in the lower part of the shaft are separated into separate easily accessible unit closed with cap, and during repairs may be replaced without disassembly contained in body and on the shaft, stators and rotors of turbines and radial bearings. Use of this design of deflecting turbodrill with bent body, body curvature may be materially increased. EFFECT: higher efficiency. 1 dwg
