摘要： A bearing assembly for use in an apparatus comprising a housing and a shaft, wherein the shaft has a shaft axis. The shaft is rotatably connected with the housing, wherein the housing defines an interior of the housing, an exterior of the housing and a first housing end. The shaft is comprised of a shaft extension which extends from the interior of the housing at the first housing end, and wherein the shaft extension defines a first bearing shaft surface, the bearing assembly comprising a first thrust bearing for transferring a first axial load between the shaft and the housing. The first thrust bearing is located axially between the first housing end and the first bearing shaft surface, and wherein the first thrust bearing is a curved bearing.

摘要： An apparatus including a housing, a shaft rotatably extending through the housing, and a rotary seal assembly contained within the housing for providing a seal between the housing and the shaft. The shaft is capable of an amount of tilting within the housing about a tilting focal point which is axially located along the housing at an axial focal point position. The rotary seal assembly is axially located along the housing at an axial rotary seal position. The axial rotary seal position is substantially axially coincident with the axial focal point position.

摘要： Variably configurable anti-rotation device (252) in a rotary steerable subterranean drill (20). The rotary steerable subterranean drill (20) includes a housing (46) with which the anti-rotation device (252) is associated. Wellbore engaging portions of the anti-rotation device (252) are positioned at an exterior (52) of the housing (46) and have a plurality of differently configurable, radially deployable drag members (254) that are peripherally spaced about the exterior (52) of the housing (46). The drag member (254) has a plurality of settable operational configurations wherein, within each configuration, the drag member (254) is deployable across a borehole engaging range of motion spanning from a start position to a maximally extended, borehole engaging position. Additionally, for at least two of the plurality of settable operational configurations, the start position of the borehole engaging range of motion is different.
