Helical cylindrical gear transmission is widely used in large industrial equipments for its good meshing performance , smooth transmission, and strong gear bearing capacity. The root crack of the helical gears was analyzed which were broken in the gear box when the excavator was in the course of work. The flaw micromechanism and affecting factors were found out accordingly.
