REVOLVING ROTOR MACHINE Russian patent published in 1998 - IPC

FIELD: mechanical engineering; pumping working medium; hydraulic or pneumatic drives of various machines. SUBSTANCE: driving and driven rotors 1 and 2 are shaped structures with helical and straight teeth. Starting leg of each section is built up of three parts: elongated epicycloid, hypocycloid, and involute; starting head is built up of involute and epicycloid. Epicycloid of one section and hypocycloid of other section are relatively rounding; radius of circumference forming them is smaller than that of centroid, that is, modulus of curves is smaller than unity. Involute of each section corresponds to its engagement line in the form of section of straight line drawn at assigned generating angle through meshing pole up to point of intersection with generating circumferences of cycloidal curves. EFFECT: enlarged functional capabilities. 2 dwg
