关于齿间及轴承间摩擦对低速齿轮机构轴承座振动之影响

The effect of frications between teeth and between bearings and journals on vibration of bearings in the low speed gearing

传统的渐开线齿轮理论不计齿间及轴承间摩擦的影响。本文的研究充分表明 ,低速齿轮机构运行时齿间及轴承间摩擦会使齿轮轴颈对轴承座作用力的大小、方向以及作用位置产生周期性的变化。显然 。

The traditional involute gearing theory omits the effect of frictions between teeth and between bearings and journals. It has fully been proved by research of this paper that frictions between teeth and between bearings and journals of the low speed gearing will make magnitudes, directions, and acting positions of actions of gear journals subjected to bearings change periodically during the gearing operating. Obviously, this periodical change of the actions will lead to bearings of the gearing to generate forced vibration.
