我厂生产的齿轮,除部分是花键配合外,绝大部分是圆孔单键配合的。圆孔单键配合齿轮的加工,又是以孔为基面的,所以孔的精度直接影响到零件的质量。过去在加工时,先要花很大的力量对每个零件进行找正,而且还不能保证完全达到图纸上要求的精确允差。我厂青年磨工、先进生产者赵殿城同志,根据齿轮嚙合的原理,创造了一种磨齿轮用的专用夹具。用这种专用夹具来磨削齿轮内孔时,只需找正第一个活就可以进行大批生产,因而提高工作效率数倍,质量百分之百的符合图
I plant the production of gears, with the exception of some splines with the vast majority of single-hole with the hole. One-click circular hole with the gear processing, but also the hole-based surface, so the accuracy of the hole directly affects the quality of parts. In the past, when processing, it took a lot of effort to find each part, and there was no guarantee that the exact tolerance required on the drawing could be fully achieved. Our mill young workers, advanced producer Zhao Diancheng comrades, according to the principle of gear meshing, to create a grinding gear with a dedicated fixture. With this special fixture to grind the gear bore, just to find the first one can be a large number of production, thus improving work efficiency several times, the quality of one hundred percent in line with the map
