WORKING SESSION downhole hydraulic motor (optional)

摘要

The proposed technical solution relates to drilling equipment and can be used for drilling wells for various purposes. New is that the shaft comprises a flexible portion and the rigid portion is a profile, the turbine sets are arranged from the turbine stages and axial bearing, wherein the rotor is a screw pair is connected to a flexible part of the shaft with the rotors of sets of turbines mounted on a rigid part of the shaft, the shaft is movable axially relative to the sets of turbine rotors, the rotors are set based on the turbine axial support autonomous set of turbines, the stator screw pair, stators kit turbines and axial supports autonomous a set of turbines fixedly secured in the housing of the working section. According to a second embodiment of a new is that the shaft comprises a flexible portion and the rigid portion is a profile, the shaft being movable axially relative to the turbine rotor, the turbine stage further have individual axial bearings, the rotor of each turbine stage through individual axial bearing rests on the corresponding a stator, wherein the stator screw pair, stators of turbine stages are fixedly mounted in the housing of the working section. Moreover, in both embodiments the rubber lining stator airend constant thickness is formed on the contact tooth profile.
