Abstract
A rotor assembly includes an oil jet assembly, an inner shaft assembly, an outer shaft assembly, and an oil mist shield. The oil jet assembly selectively ejects oil for lubrication. The inner shaft assembly is configured to rotate about a central axis. The outer shaft assembly is configured to rotate selectively about the central axis independent of the inner shaft assembly. The oil mist shield is coupled with the outer shaft and is configured to selectively block and allow the oil from the oil jet assembly from passing into a cavity.
