为保証机器的工作性能,对齿輪的强度有了更高的要求。因此,对齿輪的失效过程需要深入的探討。如何准确,簡便地記录一对齿輪在工作过程中的失效情况,已成为齿輪工作者的当务之急。对輪齿的工作情况以往多用肉眼观测輪齿表面的失效过程,此法虽簡便,但看不見微小裂紋,記录也不統一。用压鉛法或直接塑造法进行复型,对微小裂紋亦无法复 In order to ensure the working performance of the machine, there is a higher requirement on the strength of the gear. Therefore, the gear failure process needs in-depth discussion. How to accurately and simply record the failure of a pair of gears during the work process has become a top priority for gear workers. In the past, the working condition of the gear teeth was observed with naked eyes for the failure process of the gear tooth surface. Although this method is simple, it can not see the tiny cracks and the records are not uniform. With pressure lead method or direct molding method for complex type, the tiny cracks can not be complex
