“实践、认识,再实践,再认识,这种形式,循环往复以至无穷,而实践和认识之每一循环的内容,都比较地进行到了高一级的程度。”通过现场统计测试,我们对每项齿轮误差的特性,相互关系,以及误差同齿轮参数的相互关系已经取得了一定的认识,得出了某些结论。同时我们还认识到齿轮误差不仅与齿轮参数有关,同时还受加工条件的影响。因 “The practice, the knowledge, the practice, the re-recognition, the form, the reciprocity from endlessness to infinity, and the content of each cycle of practice and understanding are comparatively advanced.” Through the field statistical tests, The characteristics of each gear error, the relationship between the error and the relationship between gear parameters have gained some understanding, reached some conclusions. We also recognize that the gear error is not only related to the gear parameters, but also affected by the machining conditions. because
