<p>PROBLEM TO BE SOLVED: To provide gas turbine equipment with a lubricating oil supply apparatus, in which a suitable amount of the lubricating oil is supplied to packing for sealing an output shaft portion of a speed reducer. SOLUTION: In the gas turbine equipment, the lubricating oil which has lubricated a bearing portion of a turbine shaft is fed into a gearbox of the speed reducer by pressure air so that pressure in the gearbox becomes high. A passage is disposed to communicate with an oil seal portion for keeping the output shaft portion of the speed reducer airtight. One end of the passage communicates with the inside of the gearbox, and the other end thereof communicates with the outside of the gearbox in which pressure is lower than the inside of the gearbox. Only the mist of the lubricating oil reaches and lubricates the oil seal portion through the passage, and then the mist of lubricating oil after the lubrication is discharged to the outside of the gearbox.</p> |
