    摘要： Gearbox (1) with continuously variable parameters comprises at least one pump (2) and at least one hydraulic motor (3), wherein at least one pump (2), or a hydraulic motor (3) is with the continuously variable parameters. It consists of an input shaft (4) and one or more output shafts (5), (6) with equal or proportional continuously variable regulation of revolutions. It may be constructed as a centralized - one piece, or de-centralized, where the pump (2) is at a distance from the hydraulic motor (3) and the liquid medium passes through the hydraulic pipes (19) and (20). Pump (2) and the hydraulic motor (3) may be of the same design or different and are provided with the shift mechanism composed of a holder (13), the shift wheel (14) and the snap lock (15). Gear pump (2) with a continuously variable flow rate comprises at least one shaft (4) which holds the inner rotor (8) that is inserted into the outer rotor (7). The rotors (7),(8) are mutually axially movable. The inner rotor (8) is provided from the both sides with a sliding seal (9) with the shift screw and sliding seal (10) with compensatory cylinders are secured by snap locks (15). These parts are fitted into the central body (18), side seal (12) and side seal (11) having inlet opening (21) and outlet opening (22) connected by bypass regulated member. Compensating pistons (23) of the planar compensating system are rigidly attached to the side seal (11). Pump (2) with the continuously variable flow rate comprises at least one planar compensating system.

    摘要： A tachometer for a downhole motor includes: a tubular housing having a coupling for connection to a housing of the motor; and a probe. The probe: has a coupling for connection to a rotor of the motor, is movable relative to the tachometer housing, and has at least a portion disposed in a bore of the tachometer housing. The tachometer further includes electronics disposed in the tachometer housing and including: a battery; one or more proximity sensors for tracking an orbit of the probe; and a programmable logic controller (PLC). The PLC is operable: to receive the tracked orbit, and at least one of: to determine an angular speed of the probe using the tracked orbit, and to forecast a remaining lifespan of the motor using the tracked orbit.

    摘要： A method for forming a coating upon a wellbore tool includes forming a pattern of features supported by a body and forming a coating over the pattern of features. Forming the pattern of features includes forming a first feature and forming a second feature spaced from the first feature by a first width at a first elevation and by a second width at a second elevation, the second width being different than the first width, and the first elevation being further from an interior region of the body than the second elevation. Also disclosed is a wellbore tool comprising a coating covering a pattern of features and a method of utilizing a wellbore tool in a subterranean formation, the method including forming a pattern of features, forming a coating over the pattern, and disposing the wellbore tool in a borehole.

    摘要： A rotary fluid pressure device (11) includes a plate assembly (17) having a plate member (71) and at least one cover plate (105), which defines a mounting surface (107) adapted for sealing engagement with an exterior surface (77) of the plate member (71), or at least one control valve assembly (105), which defines a mounting surface (117) adapted for sealing engagement with the exterior surface (77). The cover plate assembly (105), when mounted to the exterior surface (77), provides fluid communication between openings (95, 97) of upstream and downstream fluid passages (91, 93), thereby providing single- speed functionality. The control valve assembly (115), when mounted to the exterior surface (77), provides selective fluid communication between the openings (95, 97) of upstream and downstream fluid passages (91, 93), thereby providing multi-speed functionality.
