Because of special geometry structure of three-cone bit, the top of formation will form a tri-spine well bottom while drilling with three-cone bit the drill string. It is the tri-spine well bottom that leads to the axial harmonic of vibration when the bit revolves a round and the three concavo-convex heave of bit and formation result in one time (1×rpm),two time (2×rpm), three time (3×rpm) turning table speed.

高岩由于三牙轮钻头的特殊几何结构，钻进过程中在岩层顶部容易形成一个三脊状井底，正是这一三脊状井底，当钻头旋转一周时钻柱轴向三次凸凹变化，由此在轴向产生1倍、2倍和3倍及其更高次倍于转盘转速rpm的谐波振动。

套装在轴上的叶轮工作时，由于离心力的影响，会使叶轮内孔增大，以至叶轮与轴之间有可能产生间隙，因此，叶轮与主轴配合必须采用过盈配合。

Installation of two outer openings each staggered 180b, the inner and outer openings staggered opening 90b, and pin the three rings with a fixed, outer and inner expansion force in self-expansion force of working together, close to the surface of the pump cylinder run, inflation is not only the axial ring sealed, and the radial seal Ye Hao, it prevents micro-fine sand and into the axial friction pair, can also prevent the micro-fine sand and into the internal voids in the inner ring 3, the operation will not impede expansion ring breathing.

安装时2个外环开口互错开180b，内环开口与外环开口错开90b，并用销钉将3个环固定，外环在自身胀力和内环胀力共同作用下，紧贴泵筒内表面运行，胀圈不但轴向密封好，而且径向密封也好，故阻止微细砂进入轴向摩擦副，也可阻止微细砂进入内环3的内部空隙中，不会阻碍胀圈运行中呼吸。
