The fOrming theOry Of arc tOOth prOfile used in single screw hydraulic machinery was analyzed. The inside rOlling en-velOpe methOd and the tOOth prOfile nOrmal line methOd were used tO sOlve the fOrmula Of cOnjugate tOOth prOfile. The flOw area and sectiOnal areas Of rOtOr and statOr were analyzed. A prOtOtype screw pump using arc tOOth prOfile was designed. The vOlu-metric efficiency Of the prOtOtype was predicted. The results shOw that the prOpOsed design scheme and mathematical fOrmulas Of Original tOOth prOfile are feasible and cOrrect. The arc tOOth prOfile is very simple and the curvature is easy cOntrOlled, it is very beneficial fOr the design, prOcessing and manufacturing. FOr the three heads screw pump with arc tOOth prOfile, its vOlumetric efficiency under the designed pressure difference remains tO be abOve 97%, and it can meet the design requirements.
