摘要： Provided is a sheet-metal turbine housing 1 in which a scroll part is formed by joining opposing scroll members made of sheet metal to form a spiral-shaped exhaust gas passage therein. The sheet-metal turbine housing 1 includes a member on a side of a bearing housing in which a bearing supporting a rotation shaft of a turbine rotor blade 50 is arranged; a member on a flow exhaust side which forms an outer side of the turbine rotor blade 50 in a direction of the turbine; and support columns 21, 40 which connect the member on the side of the bearing housing with the member on the flow exhaust side in an axial direction of the turbine and which are arranged at intervals on an outer circumferential side of the turbine rotor in a circumferential direction of the turbine rotor blade 50. Each of the support columns 21, 40 may have a cross-sectional shape in the axial direction of the turbine which includes an upstream corner and a downstream corner in a direction of a gas flow each of which has an acute angle, ¸1, ¸2 so that an upstream surface 32 and a downstream surface 34 incline along the gas flow.

摘要： A structure of a radial turbine scroll avoids a gas flow heading from a radially outer side toward a radially inner side in the vicinity of a tongue portion so as to restrain turbine performance from deteriorating and also reduces, to a maximum, thermal stress caused by the formation of the tongue portion. In the structure of a radial turbine scroll, an operating gas is led to flow in the radial direction from a spiral scroll formed in a turbine casing into turbine moving blades of a turbine rotor, which is positioned on the inner side of the scroll, so as to act on the turbine moving blades, and then led to flow outside in an axial direction, thereby rotatively driving the turbine rotor, wherein the scroll 4 has a partition plate 20 formed to have a length of a certain range on a line of a tongue portion formed on the inner periphery of a gas inlet portion or has a reduced height between scroll side walls at an outlet portion of a tongue portion 21 formed on the inner periphery of a gas inlet portion of the scroll, thereby avoiding a gas flow heading from the radially outer side to the radially inner side in the vicinity of the tongue portion.

摘要： A turbine rotor of a turbine includes a hub that serves as an axis of rotation, and a plurality of turbine blades that are arranged on a peripheral surface of the hub and receive and direct working fluid flowing into from an inlet toward an outlet. 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.

摘要： Providing a turbine wheel that includes, but not limited to: a plurality of blade parts and a scallop cut-out profile, the scallop cut-out profile being formed by cutting-out the back side wall part of the turbine wheel between the suction surface side of a blade part and the pressure surface side of the adjacent blade part, wherein the leakage flow on the rear side of the blade part is constrained so as to enhance the turbocharger efficiency. Providing the blade part 5 (i.e. the area between the scallop parts on the tip end side of the blade part) with the suction surface side extended part 25 in the neighborhood of the suction surface 21 of the blade part so that the thickness of the blade part on the tip end side of the scallop cut-out profile is increased; or, the pressure surface side extended part 32 in the neighborhood of the pressure surface 19 of the blade part so that the thickness of the blade part on the tip end side of the scallop cut-out profile is increased. Or, the positive/suction surface side extended parts are provided. Thereby, the extended width of the extended part is formed so that the width is an almost constant width along the camber line of the blade part from the tip end side to the root side of the blade, the projecting-out width part forming a strip area.
