我厂试制的TS220大马力湿地推土机,其中齿轮毂圆锥渐开线花键部分是采用引进图纸进行加工的,而齿轮毂圆锥渐开线花键是制造的关键。为此,在充分消化引进技术的基础上,我们自行设计了滚刀,在Y38滚齿机上增设了轴径向联动机构,解决了几个加工中的问题,较好地完成了圆锥渐开线花键的加工任务。加工好的工件经检查证明:表面质量,键底锥度等均能达到图纸要求。用从进口的链轮毂分别和我们的加工件及进口的齿轮毂压配证明:自制件接触面积可达80%,而进口件达
I plant trial TS220 big horsepower bulldozers, gear hub conical involute spline part is the use of imported drawings for processing, and gear hub conical involute spline is the key to manufacturing. To this end, on the basis of fully digesting the introduction of technology, we have designed the hob, Y38 gear hobbing machine to increase the shaft radial linkage, to solve a few problems in the process, a better completion of the conical involute flowers Key processing tasks. Workpieces processed by the inspection proved that: the surface quality, key bottom taper, etc. can achieve the drawing requirements. With imports from the chain wheel and our processing parts and imported gear hub pressure with proof: self-made pieces of contact area up to 80%, while the import of up to
