FIELD: oil and gas industry.
SUBSTANCE: invention refers to oil and gas well drilling and repair tooling, specifically to hydraulic turbine motors driving rock-destruction tool. Hydraulic turbine motor contains the casing, turbine spindle, axial bearing spindle with internal cylindrical cavity, tandem turbine rotors on turbine spindle. The casing accommodates turbine stators, radial bearing, turbine spindle nut, axial bearing, nipple at least one hydraulic communication facility between the last turbine rotor cavity and internal cylindrical cavity of axial bearing spindle. Turbine spindle and axial bearing spindle are threaded interconnected. Herewith rotary torque force of this threaded connection exceeds that of turbine spindle nut.
EFFECT: higher reliability, efficiency and maintainability of hydraulic turbine motor.
