从聚晶金刚石钻头（即，PDC钻头）不同的是，牙轮钻头是很难设计，因为它的几何空间的限制，轧锥和它的许多设计变量更加平衡的状态。 为了克服这个困难，外国研究人员已经开发优化技术，使得牙轮钻头，以获得第一评价的平衡，随后它的体积和压力已被重新平衡。 圆锥体的体积是碎片清除的量之间的平衡的平衡，此压力辊的平衡是能够确保遭受钻压，弯矩和轴承压力几乎是相同的。 因此，没有任何一个圆锥体或轴承系统产生过大的受力情况。

当所有滚柱和轴承是相同的压力下，所述切割结构实现了压力平衡状况。 期间排出时所有铣刀相同量的钻屑，切割结构，实现了音量平衡条件。 能量平衡（EB）指的是在钻达到压力平衡“，也达到了音量平衡。 能量平衡牙轮钻头具有的优点是通过平衡岩石由每个辊的力钻出的量，以改善牙轮钻头切削结构和接口的动态状态。 实验室和现场试验表明，光滑，牙轮钻头和冲击力的井下钻头的能量平衡遭受最小的钻头，从而提高了钻头的切削能力。 平稳，低振动定向钻井也有助于提高响应，减少疲劳失效手掌的牙齿和损坏敏感元器件钻柱的风险。

Different from polycrystalline diamond compact drill bits (ie, PDC bits) ,cone bit is harder to design more balanced state, because of its geometric space limitations, rolling cone and its many design variables. To overcome this difficulty, foreign researchers have developed optimization techniques, making the cone bit to get the balance of the first evaluation, followed by its volume and pressure has been re-balanced. The volume of the cone is a balanced equilibrium between the amounts of debris removal, the balance of the pressure roller is able to ensure suffered WOB, bending moment and bearing pressure is almost the same. Thus, there is nothing a cone or bearing system generates excessive force situation.

When all rollers and the bearing are under the same pressure, the cutting structure achieved a pressure balanced condition. During the drilling cuttings discharged when all cutters the same amount, the cutting structure to achieve a volume balance condition. Energy balance (EB) refers to both the drill reached a pressure balance', also reached a volume balance. Energy balance cone bit has the advantage that by balancing the amount of rock drilled by the force of each roller, to improve cone rock bit cutting structure and the dynamic state of the interface. Laboratory and field tests show that the energy balance of the down hole drill bit of the smoother, Tricone bit and the impact forces suffered the smallest drill, thus improving the cutting ability of the bit. Smooth, low vibration directional drilling also helps improve response, reduce the risk of fatigue failure palm teeth and damage sensitive components drill string.
