Abstract：
The rapid development of large gear was studied based on rapid casting technology.Aiming at the parting position of gear teeth in large gear with diameter of 1800 mm,the casting technology of"whole tooth"was adopted,and the development of large gear castings was carried out rapidly through pouring system design,parting design,casting machining,joint forming and melting casting.The results show that the technical scheme of"integral tooth"for the development of large gear castings has the advantages of short production cycle,low production cost,high casting structure precision and good casting surface quality.
