摘要: 本文根据实验结果,着重分析了单齿圈单牙轮钻头的运动规律。指出:牙轮绕牙轮轴的转动和钻头绕钻头轴线的转动都不是匀速的,而是变速的。此外,还简要分析了牙轮的受力情况及牙轮齿与钢井底的相互作用过程。文章结合实验结果,还分别讨论了单齿圈双牙轮钻头和单齿圈三牙轮钻头的基本运动规律。以往,国内外关于牙轮钻头运动学的文章大多假定钻头的转动和牙轮的转动是匀速转动。这与实际情况不相符。为了真正掌握牙轮钻头的运动规律,我们拟实测钻头的转速和牙轮的转速,并从最简单的,既无移轴又无超顶的单齿圈等布齿的牙轮钻头入手进行研究。

Abstract: In the present article we mainly deal with the law of motion of the single cone bit with one rim of teeth on the basis of the results of experiments. It has been proved that the motion of the cone around its own axis and that of the bit around its own axis are not uniform, but variable. Besides, we have briefly discussed how forces are exerted on The cone and how the interaction happens between the bit and The steel bottom of the well.According to the results of experiments.
