Patent ID: 10190436

Abstract:
A power transmission system for use with a turbine, a turbocharger, or a compressor has a housing, a first shaft mounted within the housing, a second shaft rotatably mounted within the housing and positioned exterior of the first shaft, a second set of blades affixed to the first shaft, and a second set of blades affixed to the second shaft. The first set of blades is positioned adjacent to the second set of blades. The first set of blades are rotatable in a direction opposite to the second shaft and the second set of blades. A shroud is affixed to an outer periphery of one of the sets of blades so as to have a portion overlying at least a portion of an outer periphery of the other of the first and second sets of blades. A power receiver is driven by the second shaft so as to convert rotational energy of the second shaft into energy or motion.
