    Abstract: Foret rotatif comprenant une fraise a rouleaux (12) se deplacant de maniere rotative sur un systeme de palier. Le systeme de palier comprend au moins un palier a rouleaux (16). Un fluide est fourni au systeme de palier de maniere a permettre la chasse et la lubrification ainsi que le refroidissement de celui-ci en cas de besoin. Afin d'assurer un ecoulement convenable du liquide au travers du palier a rouleaux (16) ainsi qu'une lubrification satisfaisante de celui-ci les rouleaux du palier a rouleaux (16) sont pourvus d'un alesage axial (25).

    Abstract: A rotary roller bit comprising at least one rotatably carried roller cutter (12) and provided with sealing means (21) for preventing impurities from entering into the bearing system (14, 15, 16) of the roller cutter. For purposes of preventing axial and wobbling movements of the roller cutter (12) relative to the bit head from creating high contact pressure at the contact surface between the sealing means (21) and the surface against which same seals the sealing means (21) is provided with an elastically yieldable tongue (25) which extends radially relative to the rotational axis of the roller cutter (12).

    Abstract: A bearing pressure system includes a bearing assembly having a first component movable against a second component and at least one accumulator in fluid communication with an interface between the first and second components, the at least one accumulator holding a pressurized fluid. A method includes providing a bearing pressure system having a fluid communicable between an accumulator and an interface between components movable relative to each other, providing an amount of pressurized fluid from the accumulator to the interface when the pressure of the fluid at the interface falls below a pressure range being maintained, and transferring an amount of the fluid from the interface to the accumulator when the pressure of the fluid at the interface rises above the pressure range being maintained.

    Abstract: A driveshaft transmission assembly may include a catch assembly having a catch mechanism and pressure plugs. The catch assembly may prevent the loss of certain driveshaft transmission assembly components downhole in the event of a failure of the driveshaft transmission due to dynamic loads produced during operation in a drilling system. The catch mechanism may be coupled to a radial bearing assembly by the pressure plugs. The pressure plugs may secure the catch mechanism to the radial bearing assembly during operation of the driveshaft transmission assembly using a normal force created by a pressure differential between downhole pressure external to the catch mechanism and ambient pressure sealed in the recesses of the radial bearing assembly.

    Abstract: The disclosure describes a constant velocity joint assembly for use in transmitting torque. The constant velocity joint assembly includes members that are connected in series via tongue-and-groove connections in a swivel joint pattern that allows for transferring torque between two skew lines, and further provide freedom of movement such that rotation about one longitudinal axis can be transformed into rotation about another longitudinal axis that is not aligned with the first longitudinal axis. Thus, the members of the constant velocity joint assembly do not necessarily need to share a common longitudinal axis.

    Abstract: A bearing assembly includes a support ring circumferentially surrounding a central bearing axis and a plurality of superhard bearing elements coupled to the support ring. Each of the plurality of superhard bearing elements has a base, a superhard bearing surface, and a lateral periphery extending between the base and the superhard bearing surface. The superhard bearing surface has a partial-ellipsoidal surface shape. A bearing apparatus includes an inner bearing assembly and an outer bearing assembly. A subterranean drilling system includes an output shaft operably coupled to a bearing apparatus.
