LONGITUDINAL VIBRATION CHARACTERISTICS OF DRILL BIT IN DRILLING RIG INFLUENCE ON WEAR AND MECHANISM OF TOOTH WHEEL END
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 mode...

| description | 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. |
