我厂百分表小齿轮原采用气体抗蚀氮化,脆性较大,用户反映使用过程中掉牙现象较严重。改为软氮化初期,由于在软氮化工艺、操作、齿轮抛光等方面存在一些问题,氮化层较薄,齿轮抛光后氮化层更薄,因此,齿轮在试验及使用过程中寿命很低。一度严重地影响了百分表的生产。遵照毛主席“团结起来,争取更大的胜利”的伟大教导,活学活用毛主席的
I used the original dial gauge gear corrosion nitriding, more brittle, the user reflects the process of falling teeth more serious. In the early stage of soft nitriding, there were some problems in the soft nitriding process, operation and gear polishing, and the nitrided layer was thinner and the nitrided layer was thinner after gear polishing. Therefore, the life span of the gear during the test and use was very high low. Once severely affected the production of dial indicator. Following Chairman Mao’s great teaching of “uniting and winning greater victories,” we should learn from Chairman Mao’s
