311毫米IADC 517G三牙轮钻头（橡胶密封轴承）
结构特点：
如图1所示，滑动轴承形式。 硬质合金牙掌轴承表面堆焊层，圆锥轴承，黄金焊接在一起银后降低，提高了承载能力和抗咬合能力;
2，轴承O型密封圈是耐磨，耐高温高饱和度的NBR，增加密封环部减小了压力密封，精心设计密封凸台以外的改进的密封的可靠性。
3，使用钢丝球或卡锁苇锥的方式，卡锁能承受高的芦苇钻压，钢珠锁定能适应高速。
4压差并防止在润滑系统中的所有橡胶储油囊钻井液的限制，轴承系统提供了良好的润滑保证。
5，250℃温度的高温，新润滑脂耐磨性。
6，采用高强度和高韧性硬质合金齿轮组步操，优化了牙行号，齿轮，露齿高度和独特的合金齿外形的设计上，充分发挥了集英尺高的耐磨性和优异的切削能力的位。 尺位齿面施加焊接新耐磨材料，并保持机械钻头标尺速度的同时，提高钻头的切削齿的生活。
产品优势：
HA系列位办理O形橡胶密封滑动轴承钻头，在常规使用能承受的压力高速钻孔，用不同的切削结构，能适应极软，硬地层。

311mm IADC 517G tricone bit (rubber seal bearing)
Structure features:
1, the sliding bearing form. Tooth palm bearing surface surfacing layer of hard alloy, cone bearing with reduced after welding together gold for silver, improve the bearing capacity and resistance to bite ability;
2, bearing type O sealing ring is wear-resistant, high temperature resistant high saturation NBR, increase the sealing ring section reduces the pressure seal, carefully designed sealing convex platform outside the improved seal reliability.
3, USES the steel ball or card lock reed cone way, card lock can endure high reed drilling pressure, steel ball to lock the can adapt to high speed.
4 the differential pressure and prevent drilling fluid restrictions in the lubricating system all rubber oil storage sac, for bearing system provides good lubrication guarantee.
5, 250 ° C temperature the high temperature, abrasion resistance of new grease.
6, set foot drill using high strength and high toughness carbide gear, optimize the design of the tooth row number, gear, toothy height and unique alloy tooth shape, give full play to the set feet high wear resistance and excellent bit of cutting ability. Ruler bit tooth face apply welding new wear-resistant materials, and to maintain the mechanical drill bit ruler speed at the same time, improve the drill bit cutting teeth life.
Product advantage:
HA series bit for O form rubber sealing sliding bearing drill bit, in a routine use can withstand high speed drilling of pressure, with different cutting structure, can adapt to a very soft and hard strata.
| Bit size | IADC | Application | Cutting structure | pressure kN/ mm | speed r/ min |
| 311mmHA637G | 517 | Low compressive strength; high drillability of soft formation; such as shale; clay; sandstone; soft limestone; etc
| Large diameter of partial top form in row tooth, wedge discharge teeth | 0.35- 1.05 | 120- 50 |
