摘要
牙轮钻头轴端的磨损是多方面因素造成的,主要从牙轮钻机钻井时钻头纵向振动特性对牙轮轴端的影响进行牙轮轴端磨损机理分析,首先建立三牙轮钻头纵向动力学模型,并在此基础上对三牙轮钻头进行振动特性分析,探究牙轮纵向振动对牙轮轴端磨损的影响,建立牙轮微动磨损数值计算模型,得出牙轮轴端的磨损体积主要受牙轮轴和轴承的接触面的法向压力和牙轮轴和轴承之间的切向相对滑移距离影响。最后对三牙轮钻头的磨损机理进行分析,对牙轮钻头寿命的提高的研究有积极的推动作用。
The abrasion of the shaft end of the cone bit is caused by many factors, In this paper, we mainly analyze the effect of the longitudinal vibration characteristic of the drill bit on the end of the tooth wheel on the wear and mechanism of the tooth axle end. And firstly, the longitudinal dynamic model of the three-cone bit is established, and on this basis, the vibration characteristics of the three-cone bit are analyzed, and the influence of the longitudinal vibration of the roller on the wear of the tooth wheel is explored, and the numerical model of fretting wear is established. It is found that the wear volume of the tooth axle end is mainly affected by the normal pressure of the contact surface of the tooth axle and the bearing and the tangential relative slip distance between the tooth axle and the bearing. At last, the paper analyzes the wear mechanism of the three-cone bit and has a positive effect on the study of the improvement of the life of the cone bit.
