A rotor assembly has been granted a patent (Publication Number: US12000299B1) that includes an oil jet assembly, inner and outer shaft assemblies, and an oil mist shield. The oil mist shield is designed to selectively block or allow oil flow between the inner and outer shafts to lubricate the inner and outer bearings. The shield moves between arrangements based on the rotation of the outer shaft, ensuring proper lubrication of the bearings. The assembly also includes a controller to manage oil flow and rotation of the shafts, enhancing operational efficiency and bearing lubrication.

Additionally, a rotor seal assembly is part of the patented technology, featuring a first and second shaft with an oil mist shield. The shield, with a conical lip design, moves to block or allow oil flow between the shafts based on the rotation of the second shaft. This design prevents oil from collecting around the seal and ensures effective lubrication of the bearings. A controller is integrated to regulate shaft rotation and oil flow, optimizing the functionality of the assembly. The method outlined in the patent involves rotating the shafts, directing oil flow, and controlling the movement of the oil mist shield to facilitate proper lubrication of the bearings, showcasing an innovative approach to rotor assembly technology.
