<p>An interchangeable tube is disposed and retained within a hollow rotor shaft of an electrical machine to form an axially extending cavity between the tube and the hollow rotor shaft. Oil flows into the tube from an oil supply, through holes in the tube, and into the cavity, and is sprayed from holes in the hollow shaft for cooling and lubricating the electrical machine. The configurations of the hollow rotor shaft and the interchangeable tube facilitate removal of the tube from the hollow rotor shaft without complete disassembly of the electrical machine. Thus, tubes having different hole diameters and hole configurations can be interchanged to accommodate different oil flow requirements and different oil pressures established by constant speed drives or auxiliary power units coupled to the electrical machine.</p> |
