FIELD: mechanical engineering; gear trains of screw machines. SUBSTANCE: one tooth surface of rotor in engageable toothed rotors having mutually embracing profiles is formed by elongated epicycloid, involute epicycloid and shortened epicycloid. Other surface of tooth is fully formed by elongated epicycloid described by point of tooth of other rotor at rolling of its centrode over centrode of first rotor. EFFECT: enhanced efficiency of screw machine due to creation of theoretically hermetic working members. 2 dwg
