軸駆動型のタービン発電機においては、界磁電流供給構
造を有する側の回転子軸にも大きなトルクが作用する。In recent years, when realizing composite cycle button electricity, there has been a demand for a so-called double-shaft drive type turbine generator in which an IQ motor is coupled to both shafts of the turbine generator and driven from both sides. In this double-shaft drive type turbine generator, a large torque also acts on the rotor shaft on the side having the field current supply structure.

粘転軸に作用する可能性が生じてきた。This torque includes not only drive torque but also transient torsional vibration l torque generated by the inertia of the prime mover in the event of a terminal short circuit of the generator or a system failure. Therefore, in a double-shaft drive type turbine generator, the blade 1 must be secured on the side with the field current supply structure, which has less shaft strength.
．． I am familiar with two points. In addition, even in conventional single-shaft drive type turbine power generation, when a shaft system with a large inertial mass such as an exciter or a rotary commutator is directly connected to the non-drive side, a simple reclosing circuit (two representative examples) is required. With the diversification of system operation in recent years, there is a possibility that excessive transient torsional vibration torque will act on the viscosity axis on the non-vertical side.

In general, the outer diameter of the shaft is approximately 50% to 75% of the outer diameter of the journal portion compared to the outer diameter of the journal. Moreover, the collector ring attachment part of the rotor shaft has a radial hole that penetrates from the outer peripheral surface of the shaft to the center hole in order to provide a collector stud that connects the center hole copper strip and the collector ring. 3Qi effort intensity (, lA, lower) due to the stress spring in.

The rotor shaft (2) has been moved from the oil cleaning area to the outer oil cleaning area (9).
The attachment of the collector ring of 1 can eliminate the radial strength of the blade, and the attachment of the collector ring can increase the axial strength of the blade. In addition, the collector ring is attached to the part where the outer diameter of the shaft is the smallest among the thin rotor parts, and the improvement in the strength of this boiling point directly leads to an improvement in the strength of the entire rotor shaft. In addition, the inverted cut section outside the machine @ i and σ(t)
The holes provided are located far beyond the collector ring attachment part of the rotor shaft (because they are provided in the thinly sliced part on the outside of the machine, which is about the same diameter as the rotor shaft), so they do not affect the strength of the rotor shaft as a whole.

The shrink-fit ring 081 has two to four radial holes in the circumferential direction that penetrate into the center hole (5) from the outside.The radial hole σ has two central hole copper strips (6) inside the bell. A conductive collector stud αυ is assembled on the rotor shaft (2).

A lateral hole (a) following ``1'' is provided, and a copper band αη that conducts electricity between the collector ring a:1 and the collector stud (Ill) is connected through the lateral hole (2).

２４１能とする。According to the present invention, the collector stud connected to the center hole copper band provided inside the center hole of the rotating shaft for supplying field current to the rotor winding is provided in the cutout on the outer side of the machine having a relatively large diameter, Since the conductor is connected to the cold outlet collector ring from the stepped part outside the machine, there is no need to provide a radial hole in the part where the collector ring has the smallest outer diameter on the rotor shaft. This improves the shaft strength of the collector ring attachment part, and since this part was the weakest part in terms of strength in the rotor thin structure of the conventional structure, the strength of the entire rotor shaft can be improved. As a result, in double-shaft drive type turbine generators, such as composite cycle power generation, an increase in the drive torque of the side arm, which has a structure that supplies field current, is used as the EJ function, increasing the capacity of the plant.
