FIELD: machine building.
SUBSTANCE: group of inventions refers to screw hydraulic machines, namely to downhole motors and screw pumps, and can be used in oil and gas, mining and other industries. Stator of the screw hydraulic machine comprises cylindrical stator housing 1, stator shell 2 installed therein, having internal helical teeth 3 to which elastomeric liner 4 is attached to the surface. Stator shell 2 on the outer surface has supporting teeth 5 located opposite its internal teeth 3.
EFFECT: invention is aimed at improving the manufacturability of the stator, increasing the reliability and improving the power characteristics of the screw hydraulic machine.
