  • Pressure switch for oil supply
    Patent number: 9562545
    Abstract: A pressure switch including a pressure chamber and a moving disc. The moving disc is moveable in response to a pressure in the pressure chamber to cause contact between a moveable contact and a fixed contact. An orifice communicates a fluid pressure into the pressure chamber. The orifice provides a tortuous path for a fluid flow to reach the pressure chamber. An oil supply system and a generator are also disclosed.
    Type: Grant

  • PRESSURE REGULATING VALVES FOR ELECTRICAL GENERATORS
    Publication number: 20150233480
    Abstract: A pressure regulating valve includes a valve body and a screen body. The screen body wraps around the valve body and joins itself at a screen joint for coupling the screen body to the valve body. A screen section defined on the screen body strains lubricant entering the valve body.

  • Gear arrangement
    Patent number: 8568089
    Abstract: An example gear arrangement includes a gearbox shaft and a journal shaft. The journal shaft establishes an opening that receives an end portion of the gearbox shaft. The gearbox shaft is configured to rotate the journal shaft. The journal shaft is configured to selectively rotatably couple with another shaft. The journal shaft is allowed to align to the bearing surface while the gearbox shaft allows for misalignment between the accessory and gearbox drive.

  • Spring actuated power swivel support rollers
    Patent number: 4877093
    Abstract: A spring actuated guide system for a top driven drilling machine. Rollers for guiding the drilling machine are mounted onto springs which urge the rollers into contact with support surfaces on parallel tracks within a derrick. If the tracks become misaligned, the springs allow for the misalignment with low roller loads thereby providing limited rotational movement of the drilling machine relative to the tracks. Premature failure of the roller bearings is prevented and wear on the rollers and tracks is reduced.
