Zusammenfassung:	WORKING MEMBER OF A HELICAL DOWNHOLE MOTOR FOR DRILLING WELLS A working member (stator or rotor) of a helical downhole motor comprises separate sections having helical teeth arranged in succession one after another and interconnected by rings. Each ring has helical teeth coinciding in pitch and direction with the pitch and direction of the helical teeth of the sections, and equidistant in profile. This allows automatic orientation of the helical teeth of the sections of the working member.
