摘要（英）：

The invention provides a design method of the circumference diameter of the technological hole of a large-size thin-walled gear. The ratio between the diameter and thickness of the gear is 10. The circumference diameter of the technological hole of gear and the diameter of the gear is 0.622-0.630. According to the design method of the circumference diameter of the technological hole of the large-size thin-walled gear, the distortion amount of the gear in the whole carburizing and quenching process can be reduced by 59% or above, the grinding amount of the gear is reduced, the manufacturing cost is greatly reduced, the gear face hardness uniformity is greatly improved, the quality of the gear is greatly improved, the bearing capacity of the gear is greatly improved, and the contact fatiguestrength and the flexural fatigue strength are greatly improved.
