| 摘 要： | 从渗碳层深度、硬度与组织、齿轮材质、裂纹区组织与硬度等方面对开裂的渗碳齿轮进行了检测和分析。结果表明,齿轮上的裂纹虽然是在渗碳淬火、回火后的磨削时发现,但系锻造裂纹,而非淬火裂纹。给出了避免出现锻造裂纹的措施。

| Abstract: | A series of experiments and analyses have been carried out on the cracking reducing gear. They include the assessment of the depth, hardness and structure of carburization case,quality of raw materials, structure and micro-hardness in cracking zone.The results show that the cracks are induced during forging of the gear even though they are discovered during the grounding process after quenching and tempering following carburization. Precautions against forging crack are given. |
