WEAR RESISTANT MATERIAL FOR THE SHIRTTAIL OUTER SURFACE OF A ROTARY CONE DRILL BIT |
摘要 |
A rotary cone drill bit includes: a body, a leg depending from the body, and a bearing shaft extending from the leg. A cone may be mounted to the bearing shaft. The leg includes a surface location that is subject to wear during operation of the bit. A bottom surface of a hard material plate is positioned with a substantially conforming surface of the leg at the location subject to wear. Positioning with the conforming surfaces is made using a flowable material such as a brazing material. |
