Предназначено для использования в горном деле для бурения скважин. Предлагаемый винтовой забойный двигатель включает двигательную секцию с переводником, шпиндельную секцию и узел соединения валов секций в виде торсиона с полумуфтой на нижнем конце. На наружной поверхности полумуфты выполнены выступы с окнами для прохода рабочей жидкости. На внутренней поверхности переводника двигательной секции выполнен кольцевой уступ для взаимодействия с выступами на полумуфте, причем между выступами на полумуфте и кольцевым уступом имеется зазор.Intended for use in mining for drilling wells. The proposed screw downhole motor includes a motor section with a sub, a spindle section and a node for connecting the shaft sections in the form of a torsion with a coupling half at the lower end. On the outer surface of the coupling half there are protrusions with windows for the passage of the working fluid. On the inner surface of the sub motor section there is an annular step for interacting with the protrusions on the coupling half, and there is a gap between the projections on the coupling half and the annular offset.
