Turbomachinery with integrated pump

摘要

The disclosed embodiments include self-lubricating oil feed systems that may include an integral bearing. The oil feed systems may include gear pumps suitable to minimize the axial profile of the oil feed systems. Additionally, the oil feed systems may be directly coupled to turbomachinery having a gear, and provide for mechanical support and lubrication of certain components of the turbomachinery. In certain embodiments, the oil feed systems enables the transfer of a lubrication fluid to the bearing during operations of the turbomachinery.
