齿轮在机械工业中占到一个特殊重要地位,所以近百年来人们在学术上也单独地将齿轮的问题作为一个独立分支。这种作法很自然,而且经验说明它取得了很好成果。关于齿轮专著和刊物几乎在所有有工业的国家里都有。近年高精技术总是愈来愈多地依靠综合手段。以传动论,齿轮传动经常与带传动、链传动、连杆、液压、电传动以及其它的控制和传感技术相结合, Gears make up a particularly important position in the machinery industry, so the issue of gear alone as a separate branch of academia has been singled out for centuries. This is a natural course of action, and experience shows that it has achieved very good results. About gear monographs and publications are available in almost all industrialized countries. In recent years, high-precision technology is always more and more dependent on comprehensive means. To drive theory, gear drives are often combined with belt drives, chain drives, connecting rods, hydraulics, electric drives, and other control and sensing technologies,
