摘要： An earth boring drill bit comprising: one or more legs; a bit body having a blade and a slot for receiving the leg; and one or more wedge between the leg and the slot fixing the leg within the slot. The slot may have two parallel sidewalls with one of the sidewalls forming an acute angle and the other forming an obtuse angle. The wedge may be secured immediately next to the obtuse angled sidewall. The wedge may have two obtuse angled sides. One or more bolts through each wedge may secure both the wedge and the leg to the bit body. In a preferred embodiment, an obtuse angled sidewall of the wedge is preferably secured immediately next to an acute angled side of the leg.

摘要： Methods of manufacturing roller cones for drill bits include providing both integral teeth and non-integral teeth on the roller cones. A layer of hardfacing may be applied to the integral teeth. Non-integral teeth may be formed on a body of a cone, or they may be separately formed from the body and attached thereto. In some embodiments, the non-integral teeth are formed by building-up the non-integral teeth from hardfacing material. Roller cones and earth-boring tools are formed using such methods.

摘要： Disclosed herein is a method of designing a roller cone bit, comprising the steps of:

a) adjusting the orientation of at least one row of teeth on a cone, in dependence on an expected trajectory of said tooth through formation material at the cutting face;
b) calculating the width of uncut rings of formation material, in dependence on the orientation of said row of teeth, and adjusting the position of said row of teeth in dependence on said calculated width; and
c) recalculating the rotational speed of said cone, if the position of said row is changed, and accordingly recalculating said trajectory of teeth in said row.
摘要翻译：本文公开了一种设计牙轮钻头的方法，包括以下步骤：a）根据切削面处的所述穿过形成材料的所述齿的预期轨迹调整牙轮上的至少一排牙齿的取向; b）根据所述排齿的取向计算未切割的地层材料的宽度，并根据所述计算的宽度调整所述排齿的位置; 以及c）如果所述排的位置改变，则重新计算所述锥体的旋转速度，并且因此重新计算所述排中的所述牙齿的轨迹。
