摘要： Roller cone drill bits may be formed with cutting elements and cutting structures having cutting element profile angles selected to minimize cone wobble and improve life of associated bearings and seals. Normal force axes of the cutting elements may intersect with each other as a force center. Crest points of the cutting elements may be disposed on one or more circles extending from the associated force center.

摘要： A roller cone drill bit may include optimally designed bearing structures and cutting structures. The roller cone drill bit may include three cone assemblies rotatably mounted on respective spindles via respective bearing structures. Each cone assembly may have a respective cutting structure with a minimal moment center located along each respective axis of rotation. Each respective bearing structure has a center point located proximate each respective minimal moment center.

摘要： Elastomeric seals for use in drill bits on which an inorganic surface modification material has been deposited onto the surface of the elastomeric seals. Wear resistance of the seal at the dynamic surface is improved by providing support for the soft seal surface, by means of the inorganic atoms, against a harder surface.
摘要翻译： 用于钻头上的弹性密封件，其上无机表面改性材料已经沉积在弹性体密封件的表面上。 通过为较软的表面提供对软密封表面的支撑，通过无机原子提供对动态表面的密封的耐磨性。
