摘要： An earth boring bit has a bearing pin with a sleeve mounted on it. The sleeve is fixed against rotation but able to float relative to the bearing pin. A cone fits over and forms a bearing surface with the sleeve. The sleeve and bearing pin are configured to have a clearance between them that has a forward portion that progressively decreases in a rearward direction. The clearance progressively decreases in a forward direction from the rearward end of the sleeve. The cone and the sleeve are able to tilt in unison with each other relative to the bearing pin when the bit is loaded.

摘要： A method for conducting nondestructive internal inspection of a rotary drill bit used for drilling subterranean formations comprises communicating ultrasonic waves into a drill bit and detecting ultrasonic waves that are reflected by at least a portion of the drill bit. In some embodiments, the waves may be directed into the drill bit from within a longitudinal bore thereof. Reflected waves also may be detected from within the bore. The methods may be used to develop threshold acceptance criteria for classifying drill bits as acceptable or unacceptable to prevent catastrophic failures of drill bits during use. Systems and apparatuses are disclosed for conducting nondestructive ultrasonic inspection of a drill bit used for drilling subterranean formations. The systems and apparatuses may comprise an ultrasonic probe configured for insertion within an internal longitudinal bore of a drill bit. Drill bits are disclosed that are configured to facilitate nondestructive ultrasonic inspection thereof.

摘要： An earth boring bit has sliding engaging surfaces between a cone assembly and a bearing pin. Micropores are formed in at least one of the engaging surfaces. Each of the micropores has a leading portion and a trailing portion. The leading portion is at a more gradual slope than the trailing portion. The micropores are located in a pattern of a greater density in a region of the engaging surfaces that operate at higher pressures than in other regions.
