Patent
IHI Corporation | Date: 2017-01-25

A plurality of variable nozzles is provided at equal intervals in a circumferential direction so as to surround a turbine wheel between a facing surface of a first nozzle ring and a facing surface of a second nozzle ring. The first nozzle ring is constituted by three nozzle ring segments laminated along the axial direction. In the three nozzle ring segments, a thickness of the nozzle ring segment on a side far from the bearing housing is smaller than a thickness of the nozzle ring segment on a side close to the bearing housing.

In a variable-flow-rate valve mechanism, a valve is fitted into an attachment hole of an attachment member. The valve allows for play with the attachment member, and includes a valve body provided with a valve surface. A valve shaft is integrally formed in the center of a head portion of the valve body. A stopping member is provided to a leading end portion of the valve shaft. A leaf spring is provided to the valve shaft. The leaf spring includes a folded-back portion formed by bending. An insertion hole is formed in one end portion of the leaf spring. A cutout portion is formed in another end portion of the leaf spring. The one end portion of the leaf spring is fixed to the attachment member and the other end portion of the leaf spring is pressed to the head portion of the valve body.


A lubricating oil line of a gas turbine or a turbocharger includes a flow path component which allows passage of a lubricating oil. The flow path component used in the gas turbine includes a sump chamber (45) and a vent line (49). A surface of the flow path component, which is exposed to a temperature approximately from 300 to 450C and comes into contact with the lubricating oil, is covered with a coating that includes nickel or a nickel-phosphorus alloy, and particles made of polytetrafluoroethylene.

In the process of cutting the outer circumference 10o of a hollow rotating shaft 10 by using a finishing turning tool 36, the position of the finishing turning tool 36 is adjusted in the direction orthogonal to the virtual reference shaft center VS so that the center position CPo of the outer circumference 10o of the hollow rotating shaft 10 is deviated from the virtual reference shaft center VS in the same direction as the direction of the deviation vector Di by an amount corresponding to the magnitude |Di| of the deviation vector Di. This can reduce the unbalance to zero also in the middle of the shaft and sufficiently reduce runout of the hollow rotating shaft 10 even if the rotation speed of the hollow rotating shaft 10 increases. Accordingly, it is possible to further improve the reliability of the hollow rotating shaft 10 at high rotation speed.

A valve is provided fitted into a mounting hole of a mounting member. The valve is allowed to have play with respect to the mounting member. The valve includes a valve body having a valve surface capable of being brought into contact with and being separated from a valve seat. A valve shaft is integrally formed on a head of the valve body. An axial center of the bypass passage is inclined with respect to a thickness direction of an inner wall portion of a turbine housing so that an opening portion on an outlet side in the bypass passage is located closer to a stem side than an opening portion on an inlet side. A center of the valve surface of the valve body is eccentric to the stem side with respect to an axial center of the valve shaft.
