摘要： A high capacity thrust bearing is disclosed for use in a tubular drilling string to support axial loads resulting from upward or downward jarring forces. The thrust bearing comprises an inner mandrel and an outer housing. A mandrel pressure chamber string and a housing pressure chamber string are journalled between the mandrel and the housing. The mandrel pressure chamber string and the housing chamber string are arranged to form a number of individual pressure chambers. Alternating pressure chambers contain high pressure fluid or low pressure fluid, thereby forming a repeating pressure differential between adjacent chambers. As loads are applied axially to the drill string, such as jarring loads, the pressure differential over the surface area of the pressure chambers provides a thrust bearing. The thrust bearing is rotatable by its connection to the drill string.

摘要： There is disclosed an improved bearing and particularly an improved bearing assembly (15, 15A), eg. a thrust bearing assembly, which may be used in down-hole applications, such as down-hole drilling applications. Thrust bearing assemblies for use in down-hole applications have the conflicting requirements of a thick shaft assembly and high axial load bearing capacity in a small crosssection. The invention, therefore, provides: a bearing assembly (15, 15A) having at least two bearing elements (400, 400A) spaced by a first body (500, 500A), the first body (500, 500A) having means for flexing. Thus when a load is applied to the bearing assembly (15, 15A) the first body (500, 500A) is caused to flex. In an embodiment the flexing means comprise at least one circumferential groove or notch (510, 510A) formed on the first body (500, 500A).

摘要： A down hole motor assembly which comprises an hydraulic drive portion, a drill bit operatively connected to the drive portion and a disengage mechanism (11) arranged to disengage drive to the drill bit. The disengage mechanism (11) is arranged to be actuated by supplying drilling fluid to the drive portion at a flow rate which is greater than the flow rate at which fluid is supplied to run the drive portion during normal drilling. The disengage mechanism being arranged to be re-set so that drive is reconnected to the drill bit when the fluid supply to the drive portion is shut off.

摘要： A down-hole rock drilling machine (in-hole rock drilling machine) has a carrier sleeve (22) mounted in combined axial and radial bearings (21, 22 and 23, 24) and the carrier sleeve carries a guiding tube (30) laterally of the machine with an element (31) inbetween. The bearings (21, 22 and 23, 24) and the carrier sleeve (22) are held axially together between a shoulder (17) on the machine housing (11) and a drill bit holding sleeve (13). The machine housing will be subjected to strong vibrations, but since the bit holding sleeve (13) is screwed to the machine housing (11) and transmits the rotation to the drill bit (14), the carrier sleeve bearing arrangement will be secured.

摘要： A rotary drill bit (22) for drilling a curved subterranean borehole (26). In one embodiment, the drill bit comprises a side portion (40), a plurality of cutting elements (44) that produce a lateral force on the drill bit (22) in response to the rotation of the drill bit in the borehole, and bearing means (48). The bearing means is located on the side portion (40) of the drill bit (22) and contacts the borehole wall (28) during drilling to receive a reactive force that is from the borehole, that is in response to the lateral force and that is directed to a location adjacent to the uphole end of the side portion of the drill bit (22). The reactive force and the lateral force form a downhole-moment that is about the drill bit and that is opposed by an uphole-moment having a force component that is directed at the flexible joint (186). The uphole end of the bearing means (48) is located relatively close to the cutting elements (44) such that the magnitude of the downhole-moment and the magnitude of the uphole-moment are minimized.

摘要： Devices, systems, and methods for stabilizing a gyroscopic sensor include bearings supporting a MEMS-type gyroscope located in a shell. The shell rotates around a secondary shaft connected to an extension arm of a primary shaft. A biasing element pre-loads thrust bearings on either side of the shell against the extension arm, which can limit motion of the shell during operation of the sensor, thereby improving measurements made by the sensor.
