20120082552 | TURBINE ROTOR - A turbine rotor of a turbine includes a hub that serves as an axis of rotation, and a plurality of turbine blades. The turbine blades each have a line extending along a shroud-side edge of the turbine blade from the inlet to the outlet as a shroud line. The shroud line includes an entrance-side shroud line La that makes a small change from the inlet toward the outlet in a blade angle with respect to the axis of rotation, a center shroud line Lb that extends from the outlet side of the entrance-side shroud line La and makes a greater change than that of the entrance-side shroud line La, and an exit-side shroud line Lc that extends from the outlet side of the center shroud line Lb to the outlet and makes a smaller change than that of the center shroud line Lb. | 04-05-2012 |
20120183406 | TURBINE ROTOR - Providing a turbine rotor in which the rotational inertia of the turbine rotor can be reduced without changing the geometry of the blade part, whereas the turbine rotor is provided with the rear side surface so that the stress concentration appearing at the root part regarding the hub part on the rear surface side is constrained in order that the strength and the durability of the turbine rotor can be enhanced. A turbine rotor that comprises a hub part | 07-19-2012 |
20120275914 | TURBINE HOUSING - A sheet-metal turbine housing has a scroll part formed by joining opposing scroll members of sheet metal to form a spiral-shaped exhaust gas passage. The housing includes a member on a side of a bearing housing inclosing a bearing supporting a rotation shaft of a turbine rotor blade member on the exhaust side forms an outer side of the turbine rotor blade. Support columns connect the member on the side of the bearing housing with the member on the exhaust side in an axial direction of the turbine and are arranged at intervals on an outer circumference of the turbine. Each support columns may have a cross-sectional shape which includes an upstream corner and a downstream corner in a direction of a gas flow, each of which has an acute angle, so that an upstream surface and a downstream surface are inclined to the gas flow. | 11-01-2012 |
20130004321 | TURBINE WHEEL - A turbine wheel includes a plurality of blades having a scallop cut-out profile. The scallop cut-out profile is formed by cutting-out a back side wall part of the blade between the suction surface side of a blade part and the pressure surface side of the adjacent blade. | 01-03-2013 |

20140147306 | STRUCTURE AND METHOD FOR ADJUSTING BALANCE OF TURBOCHARGING DEVICE INCORPORATING ELECTRIC MOTOR - An object is to increase portions (increase the amount of correction), where the rotational balance of a rotary shaft of a turbocharging device incorporating an electric motor is adjusted, and to maintain sufficient motor driving force even under a high temperature condition. In a balance adjusting structure for the turbocharging device incorporating an electric motor, a rotor core | 05-29-2014 |
20140341729 | RADIAL TURBINE - A radial turbine comprises a plurality of nozzle vanes disposed along a circumferential direction inside a spiral scroll and configured to regulate a flow of a working gas from the scroll to a rotor blade, wherein each of the nozzle vane includes a leading edge bulging portion on both end portions in a width direction of an inlet leading edge portion, the leading edge bulging portion being bulged toward a pressure face side of the nozzle vane relative to a central portion, so that a vane angle is configured to correspond with an inflow angle of the working gas to be flown into the nozzle vane, and wherein each of the nozzle vane includes a trailing edge bulging portion on both end portions in a width direction of an outlet trailing edge portion, the trailing edge bulging portion being bulged toward the pressure face side relative to a central portion, so that an outflow angle of the working gas from the outlet trailing edge of the nozzle vane becomes uniform. | 11-20-2014 |
