20120076448 | Keyless Bearing Sleeve for Subterranean Applications - A sleeve is retained to a shaft without the use of a keyway through at least one end connection that has a preferably flat face with one or more projections from the flat face. Rounded projections are preferred. The projections go into shape matching depressions on the sleeve. Alternatively the sleeve can have the projections and the end retainer can have the depressions. The end retainer is spring loaded for axial deflection in the event of an over-torque. If that happens there is planned for slippage until the condition is alleviated at which point the spring bias is able to again match a projection to a depression for continuing tandem driving of the shaft and the sleeve. The sleeve is preferably carbide and resides in a carbide bushing. | 03-29-2012 |
20130040480 | Isolated Pressure Compensating Electric Motor Connection and Related Methods - Isolated pressure compensating electrical motor connections and related methods are provided. According to an example of a sealed motor electrical connection, the connection incorporates a sealed female motor connection positioned to receive a male motor connector. The female motor connector has one or more independent dielectric oil chambers each pressure compensated by a bellow or similar device interfaced with the motorhead oil and/or well annulus fluid to thereby pressure compensate the chamber pressure of the female motor connection with that of the internal motor and/or well annulus. This configuration locates the electrical connection point of the motor lead extension with the motor lead wires to a separate area outside the motor to thereby prevent the occurrence of phase to phase or phase to ground shorts occurring in this critical area due to conductive element contamination that may reside in the motor oil or the well bore fluids. | 02-14-2013 |
20140144695 | Systems and Methods for Coupling a Power Cable to a Downhole Motor Using a Penetrator - Systems and methods for providing power to downhole equipment, where an electrical penetrator is installed through the housing of the equipment to provide a high pressure seal between the interior and exterior of the equipment's housing.

Each of the conductors extends through the penetrator body. The inner body is sealed against both the conductors and the outer body by bonding them together, for example. The ends of the conductors which extend into the housing are connected to the motor or other equipment, while the ends of the conductors which to the exterior of the housing are connected to a power cable. | 05-29-2014 |
20140271107 | Systems and Methods for Preventing Damage to Pump Diffusers - Systems and methods for preventing diffusers in pumps such as electric submersible pumps from bursting or collapsing in over-pressure and/or under-pressure conditions, where one or more diffusers in the pump includes check valves in the exterior diffuser wall. The check valves remain closed when a pressure differential between the diffuser interior and exterior is within a predetermined range, but open when the pressure differential between the diffuser interior and the interstitial space is outside the predetermined range to relieve overpressure and underpressure conditions. When the pressure differential returns to an acceptable range, the check valves close, preventing recirculation of fluid between the diffusers of the different stages. O-rings or other types of seals may be installed between each stage and the pump housing to provide some isolation of the external pressure on the diffuser of each stage. | 09-18-2014 |

The insulating material may alternatively have an interference fit with the outer housing and the inner conductor. The connector bodies may have standardized connector interfaces to facilitate connection to complementary standardized connector interfaces on cable-end connectors, etc. Connector bodies may be formed as motor heads, mandrels for cable splices, penetrators, etc. | 11-13-2014 |
