主要结构

1. TCI牙轮钻头的挖掘和凿岩钎
刀片的强度和耐磨性提高通过使用硬质合金刀片，具有高强度

和高耐磨性。
表面采用先进的热处理工艺，以提高负载能力和使用寿命轴承的治疗的高精密轴承的热量。
轴承的使用寿命，采用进一步扩展更加努力，莫特穿推力轴承耐磨材料。
防止回流结构具有双重功能，这样可避免空气逆流和灰尘进入轴承当空气压缩机停止工作意外，和独立的空气和水，以避免水进入轴承，当它正常工作，延长轴承的寿命。

插入TRICON位
1.该系列三牙轮钻头使用密封式滚子轴承结构。 与滚子排列在沟槽中凹进设置在所述锥体，轴承轴颈的尺寸增大。
2.推力轴承表面硬面和减小摩擦技术处理。
3.球锁定锥，适合高转速。
3. TCI百胜位
1本系列三牙轮钻头使用滑动轴承。 硬面头轴承表面。 锥轴承镶嵌有减摩合金，然后镀银。 轴承的负载容量和耐发热胶着性得到很大提高。
2. O形圈密封件由越耐磨性高饱和丁腈橡胶的与增加的密封部和精确设计在锥形密封区域的密封凸缘增加了密封的可靠性。
3.该位轴承可锁定球
4.对于钢齿位，齿面是硬面与新型磨损resistan的
材料，从而延长工作的切削结构的寿命，同时仍保持较高的机械钻速。

Main structure

1. TCI tricone bits for Mining and Rock Drilling
The strength and wear resistance of inserts are improve by using carbide inserts with high strength

and high wear resistance.
Surface of the high precision bearing heat treated by using advanced heat treatment process to improve the load capacity and service life of the bearing.
The service life of the bearing is further extended by adopting harder and mort wear resistant material for thrust bearing.
Preventing reflux structure has dual function, it can avoid air counterflow and dust entering into bearing when the air-compressor stop working accidentally, and separate air and water in order to avoid water entering into bearing when it works normally to prolong the life of bearing.
2TCI tricone bits for Oil Drilling
Inserted tricon bits
1. This series tricone bit use Sealed roller bearing structure. With rollers arranged in grooves recessed in the cone body, the size of the bearing journal is increased.
2. Thrust bearing surfaces are hardfaced and treated with friction reducing technology.
3. Ball locked cone, suitable for high rotary speed.
3. TCI Tricon bits
1 This series tricone bit use Journal bearing. Hardfaced head bearing surface. Cone bearing inlaid with friction reducing alloy and then silver-plated. The load capacity and seizure resistance of the bearing is greatly improved.
2. O ring seal is made of the more wear resistance high saturated buna-N with the increased seal section and precisely designed sealing flange in the cone sealing area increased the reliability of the seal.
3. The bit bearing can be ball locked
4. For steel tooth bit, the tooth surface is hardfaced with new type of wear resistan
Material and thus extended working life of the cutting structure while still maintaining high ROP.
