The invention discloses a vacuum gas quenching strengthening method for a 13Cr14Co3NiMoCuNb gear. The vacuum gas quenching strengthening method comprises the following steps of: (1) performing vacuum gas quenching; comprising the following steps: S1, quenching a gear; s2, the quenched gear is subjected to ice cooling; and S3, the gear subjected to ice cooling is subjected to tempering. According to the method, the hardness and the strength of the 13Cr14Co3NiMoCuNb gear can be improved. 本发明公开了一种13Cr14Co3NiMoCuNb齿轮真空气淬强化方法。包括以下步骤：S1.对齿轮进行淬火；S2.对淬火后的齿轮进行冰冷；S3.对冰冷后的齿轮进行回火。本发明能够提高13Cr14Co3NiMoCuNb齿轮的硬度和强度。
