MATED ROTORS Russian patent published in 1998 - IPC

Abstract RU 2112885 C1

FIELD: jet and vacuum pumps, hydro and pneumatic motors, rotor-type internal combustion engines. SUBSTANCE: involute teeth 5, working teeth 4 and recesses 3 corresponding to them engaged with rotation of rotor are located along outer circumferences of mated rotors. Shape of working teeth 4 and recesses 3 is determined in agreement with special design formulas. With rotation of rotors working tooth 4 engages mated recess 3. In this case characteristics of their uniform rotation along circumference coincide with characteristics of rotation of involute tooth 5 which ensures uniform rotational speed. EFFECT: ensured uniform rotational speed. 12 dwg , 2 tbl
