putting a journal bearing at each end of the turbine rotor or shaft would be to support it.
Can you please send to me Turbine parts and function of each part shortly?
it's the thermal expansion in the casing of hp or ip turbine can be noticed by journal or thrust bearing when moving <<
The major function of the turbine in the turbojet is that it supplies the power to turn the compressor. An automatic fuel control unit on a turbojet engine is influenced by the burner pressure.
Thrust pads are used to protect the steam turbine rotor from damage due to axial displacement due to axial thrust created by entry of steam in the turbine. generaly the pads clearence is 0.45mm for a bearing size 250mm.
Turbine thrust bearing active and inactive temperature is the blade in the turbine trust bearing is actual temperature change, which mitigates the active or inactive bearing.
main two type of bearing used in steam turbine:(1)thrust bearing (2)general bearing

The function of IGV in a gas turbine is to prevent surges and stall conditions.
to support crankshaft
The function of the bearing in a combustion engine is to offer lubrication.

generally more than three shafts contact by coupling together in steam turbine. the shaft is heavry and will be sag. in order to reduce the bend force on coupling and bend force on bearing, the engienering calclated the shaft and simulated when its in operation condition. so, the catenary curve and bearing elevation data have been provided for steam turbine installation.

it is used balance axial thrust on turbine rotor due to admitting of high pressure steam in to turbine. it basic purpose is to save thrust bearing.

The function of the wasegate valve is to divert exhaust gases away from the turbine in the engine system. This enables it to control the speed of the turbine.
