摘要： An energizer for a mechanical seal assembly for use in a drill bit is disclosed. The energizer is a composite of at least two resilient materials, one having a durometer hardness that is greater than the other. The material contacting a journal provides relatively high frictional forces so as to prevent the energizer from rotating in relation to adjacent components. The relatively softer resilient material provides the energizing force necessary to maintain a good dynamic seal between the metal seal rings. The energizer components may be separate components that engage one another upon assembly, or may be bonded together to form a ring prior to assembly into the drill bit.

摘要： A rolling cone bit and a cutting insert for a rolling cone are disclosed. The insert includes an undulating cutting surface including a peak, and blades radiating therefrom. The cutting insert may include an ultrahard layer of diamond or other superabrasive material, wherein the outer cutting surface of the layer includes contours that generally correspond to the contours of the interface surface that is between the ultrahard layer and the substrate so as to reduce residual stresses and lessen the likelihood of spalling or delamination of the ultrahard material. The blades radiate from a central peak and may include a sharper and/or higher leading edge as compared to a trailing edge. Valleys between the blades may differ in depth, and the cutting surface may have an undulating perimeter.

摘要： Disclosed is a seal assembly for dynamically sealing between rotatable members, such as employed to seal the rolling cone of a rock bit. One preferred assembly includes an energizer, first and second seal rings, and a cushioning ring having an L-shaped cross-section disposed about portions of one of the seal rings to seal and absorb impact loads and thereby protect the more-rigid seal rings.
