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