摘要： A chemically implemented method is disclosed for producing structural connections between pairs of members, a portion of the first member being telescoped within an opening formed by and within the second member, such connections being substantially comparable in strength and rigidity to connections produced by forced fit or by thermal shrinkage methods.Members are formed to provide for mutual fits which may range from "coarse clearance fit" to "light push fit", allowing generally for hand assembly. Prior to assembly the interfacing surfaces are coated with simple ferrous oxide. After assembly the members are clamped or supported temporarily to provide immobility to the joint during the expansive conversion of simple ferrous oxide to higher levels of ferric oxide via the introduction of hydrogen peroxide solution of at least 15% concentration into the interstices of the joint. The clamp or support is then removed leaving a strong and compressively impacted joint.In the eventuality that the joint is to be disassembled for maintenance, repair, or transportation, a penetrating solvent solution providing a reduction reaction is used to dissolve and weaken the impacting oxides.

摘要： A heavy-duty composite radial journal bearing and a method to produce it is described. A pattern of openings is formed through a bearing sleeve representing, for instance, axially aligned metal bars. The openings are subsequently filled wth a metal dissimilar to the sleeve. Filling may be done with the sleeve in place either on a journal or in a housing, in which case the bearing becomes integral to that member by fusion. Alternately, the sleeve may be filled upon a nonwettable mandrel and subsequently used as a floating ring or as a bushing. Final finish machining reveals a pattern which exists throughout the bearing of alternating areas of relatively hard metal and a softer antigalling metal.

摘要： A rotary rock bit is described having a plurality of legs extending downwardly from the main bit body. Each leg includes an annular bore extending through the lower extremity thereof. A separate journal pin is provided for each leg, with each journal pin having a mounting end and a bearing end. The mounting end of each journal pin is adapted to extend into the bore of a respective leg and be secured thereto by an electron beam welding process. The bearing end of the journal pin is adapted to receive an annular thrust member extending over the bearing surface thereof. The annular thrust member is secured to the journal pin by the same electron beam welding process step which welds the journal pin to the bore of the leg. A cone type cutter is adapted to be rotatably mounted on the bearing end of each journal pin with the annular thrust member functioning to retain the cutter on the journal pin and to absorb the in and out-thrust and radial loads passing therethrough.

摘要： A rotating cone drill bit includes a plurality of mud nozzles extending from the bit body, which are thermally fitted by controlling the temperature differential of 300° F.-900° F. depending on the corresponding materials of the elements to be fitted, the amount of fit desired, and the diameters of the elements to be fitted and which provide substantially obstruction-free mud paths toward the wellbore bottom. The bit has a plurality of reduced diameter cutter assemblies, each having a journal projecting from a corresponding leg. The journal has at least two cylindrical bearing surfaces and an annular groove formed therebetween and a spindle. An annular retention segment is rotatably mounted in the groove. The retention segment has an outer radial surface engaging a portion of one of the bearing surfaces of the cone, and an energy beam welding area fusing substantially the entire engaging surfaces of the retention segment and the cone.

摘要： A rotary cone rock bit featuring a reproducible geometry and a one piece body is disclosed. Individual journal members, supporting rotary cutting cones, have upwardly extending structural shanks which are radially oriented and installed into downwardly directed individual hubs formed by the structural body of the rock bit. The shanks are subsequently secured as installed within the hubs. The primary controls over bit geometry comprise the radial orientation of the individual journal member, and the radial location of the individual hubs relative to the vertical bit body centerline.

摘要： A method of providing a selected bearing couple in a journal bearing of a rotary rock bit is described, wherein differential thermal expansion is used to mate a thin walled bushing of a chosen bearing alloy to one of the steel structural members. A pre-finished and pre-heat treated thin walled bushing is formed of the desired bearing alloy. Very little valuable space is required by the thin walled bushing. The use of arc-deposited metal, press fitting, or of loose parts is avoided, and many potential bearing alloys are adaptable as candidates for use in such a bushing.

摘要： A method of securing hard-metal, insert type, rock cutting teeth into the supporting structures of rock bits is described, wherein the thermal expansion characteristics of the materials of the supporting structure, and of the hard-metal teeth, with widely differential temperatures, are relied upon to relatively enlarge the dimensions of undersized retention bores formed by and within the supporting structure with respect to the dimensions of insertable rock cutting teeth, thus permitting insertion of the rock cutting teeth into the undersized retention bores. Subsequent equalization of the temperature of the assembly will tightly retain such teeth within the retention bores.
