Summary:The utility model discloses a main reducing gear shell body. The main reducing gear shell body (1) is manufactured by using of lost foam casting technology. A copper bush (11) is embedded at the position of a piston hole in a casting in a matched and locked mode. A sealing ring (12) is embedded in a front groove and in a rear groove of a piston bar (9), wherein the piston bar (9) is matched with the piston hole. According to the main reducing gear shell body, quality of the casting is greatly improved, air leakage of the piston hole and the matched piston bar cannot occur, and therefore normal operation of a poking fork does not be affected.
