Claims

[Scope of utility model registration request]

A main shaft is rotatably supported by a rolling bearing, a compressor is connected to one end of the main shaft, and a turbine is connected to the other end, and oil from an oil pump is supplied to the rolling bearing based on the output of a control means, and
In a gas turbine in which a driving force is applied to a main shaft by a starting means at the time of startup, a temperature detecting means for detecting the temperature of the oil and a rotation detecting means for detecting the rotation speed of the main shaft are provided, and the control means includes: The main shaft is accelerated by the starting means without supplying oil when the oil temperature is below a predetermined value at the time of startup, and when the main shaft reaches a predetermined rotation speed, the oil is controlled to be supplied to the rolling bearing. gas turbine.
