锥体结构特征

1.切削结构

优质钨硬质合金刀片的耐久性与新配方和插入位的新技术改进。

2.计结构

与计剪的脚跟和压力表插入多计保护，锥，钨硬质合金刀片和堆焊在下摆增加的规表面衡量保持能力和轴承寿命。

3.轴承结构

高精密轴承有两个推力的面孔。 球锁定锥。 硬面听到轴承表面。 圆锥轴承镶嵌有减摩合金，然后镀银。 耐磨性和轴承的耐发热胶着性得到改善，并适用于高转速。

三牙轮钻头切削结构：很长的间隔较宽，凿形刀片和相当大锥轴偏移量对位的中心线确保很高的普及率。 为了确保从直径损失该位，保径镶已经得到了更短的长度和顶部的更大的角度。 阵型：长的时间间隔很软很差压实的页岩，砂岩，粘土，盐和软mestones的。 大小和IADC可供选择：2 7/8至26 IADC 114 117 216 217 317 321 417 437 517 537 617 637等。

三牙轮钻头的参数化绘图系统采用模块化程序设计方法; 整个系统被分成四个功能模块：用户界面管理模块，齿面的结构设计模块，数据库管理模块和参数化绘图模块的位。 的用户界面使用VBA，这是嵌入在AutoCAD中，牙轮钻头设计的性能，实现第二个工具的开发。 通过三个牙轮钻头设计用户接口模块输入相关参数的用户，实现人机对话。 位齿构造设计模块的主要功能是根据三个牙轮钻头3位数据的理论为复杂计算的设计而设计的。 数据库管理模块是由Access 2003中从建立数据库的数据。

Characteristics of Cone Structure

1. Cutting Structure

The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.

2. Gauge Structure

Multiple gauge protection with gauge trimmers on heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life.

3. Bearing Structure

High precision bearing with two thrust faces. Balls lock the cone. Hardface heard bearing surface. Cone bearing inlaid with friction-reducing alloy and then silver-plated. Abrasion resistance and seizure resistance of the bearing are improved and suitable for high rotary speed.

Tricone bit Cutting structure: very long widely spaced , chisel-shaped inserts and considerable cone axis offset against center line of bit ensure very high penetration rate . To secure the bit from diameter loss, the gage protection inserts have got shorter length and greater angle of the top. Formations: long intervals of very soft poorly compacted shale, sandstone, clays, salts and soft mestones. Size and IADC available: 2 7/8 to 26 IADC 114 117 216 217 317 321 417 437 517 537 617 637 and so on.

The parametric drawing system of three teeth wheel drill adopts the modular programming method; the whole system is divided into four functional modules: user interface management module, the bit of tooth surface structure design module, database management module and parametric drawing module. The performance of roller cone bit design of user interface use VBA, which is embedded in AutoCAD, to realize second tools development. The user through the user interface module input relevant parameters of three cone bit design to realize the man-machine communication. The main function of the bit teeth structure design module is designed according to the theory of three cone bit three bit data for the design of complex calculations. Database management module is composed of Access 2003 as a data from the establishment of the database.
