Also, liquid water entering the blades may damage the thrust bearings for the turbine shaft.
This is attached to the main turbine shaft and does the same job as the air starter motor.
This allows the generator to be integrated with the turbine shaft, and to double as the starter motor.
When it stops completely, there is a tendency for the turbine shaft to deflect or bend if allowed to remain in one position too long.
These ball bearings are designed to be used with a smaller and lighter turbine shaft.
Among the components principally upgraded were the turbine shafts and runners.
Then he saw Nelson, lying at the center of the pit on the temporary woodwork covering the turbine shaft.
In 1994, an unused turbine shaft from the old cotton mill site was uncovered and filled with cement.
The actual output at the turbine shaft is equal to the stage work minus the losses due to rotor disc and bearing friction.
The resulting impulse spins the turbine runner, imparting energy to the turbine shaft.
