摘要： When changing a nozzle blade angle by rotating a drive ring, a contact load generated between an inner circumferential surface of the drive ring and an outer circumferential surface of a mount can be reduced, allowing the drive ring to rotate smoothly and reducing the amount of wear and a driving force. It is also possible to reduce an impact force, such as engine vibrations, generated at the drive ring when an external force acts, reducing the risk of damage. A plurality of notches (19) are provided at an inner rim of the drive ring (14), and, among inner circumferential surfaces (14a, 14b, 14c, 14d, 14e, 14f, 14g, and 14h) located between the notches (19), when a driving force for rotating the drive ring (14) is applied, the inner diameters of the inner circumferential surfaces (14e, 14f, 14g, and 14h) where the contact load with the outer circumferential surface of a mount becomes large are made larger than the outer diameter of the outer circumferential surface.

摘要： A method and device for assembling and adjusting the pivotable nozzle vanes of a variable capacity turbine, making it possible that the nozzle vane setting of the adjustable nozzle mechanism is done with high accuracy without being influenced by the accuracy in dimensions of the constituent parts such as nozzle vane and annular link mechanism and that the adjustable nozzle vane mechanism is adjustable whenever necessary even after the turbine is assembled. The nozzle vanes are temporarily encircled and bound with a binding member capable of binding/releasing such as belt, etc. When the vanes are perfectly closed with the vanes contacting each other, then the nozzle vanes are fixed to the connection parts of the annular link mechanism with the vanes in the temporarily bound state.

摘要： The object of this invention is to eliminate the quantity of exhaust gas supplied to the turbine without going through the channels between the nozzle vanes provided in a variable-capacity turbocharger. The nozzle unit (100) in the turbocharger (10) has a mounting plate (102) and a side plate (106) installed in a recession (20) provided in the housing (20) in such a way that the side plate can move in the recession, both of which are provided parallel to the turbine shaft; a pushing means (116,150) to push the side plate toward the mounting plate (102); and a limiting means (108) to limit the movement of the side plate parallel to the turbine shaft toward the mounting plate (102).

摘要： The object of this invention is to propose a manufacturing method for manufacturing component part for the variable capacity turbine, and the structure of the nozzle driving member, which will simplify the structure of the component part for the adjustable nozzle mechanism, the manufacturing work which results in lowering the manufacturing count and cost, as well as the number of component part, and in lightening the weight of the variable capacity turbine. In order to manufacture the component part for a radial-flow variable capacity turbine, in which the actuating gas is forced to flow from a spiral scroll formed in the turbine casing to a turbine rotor in a radial direction, through multiple nozzle vanes of which the angle is adjustable by an adjustable nozzle mechanism, for rotating the turbine rotor, this manufacturing method according to this invention is distinguished by the configuration in which a column shaped connecting pin is formed as a single structure with a plate member by a pressing, or a precision molding by partially forcing the surface of the plate member to protrude in a column shape.

摘要： Variable nozzle drive mechanism with a link plate (112), which can operate all the nozzle vanes smoothly and synchronously. The nozzle vanes (104) are supported in such a way that the nozzle vanes are free to rotate between the open and closed positions on nozzle shafts (104a), and the nozzle vanes (104) are connected to levers (114) which correspond to the nozzle shafts (104a) so as to rotate along with the levers (114). Each boss (114a) at the end of each lever (114) functions as a shaft which are parallel to the nozzle shaft. The shafts (114a) in the nozzle vanes engage in oblong holes (114a) in the link plate (112) in such a way that they are free to swing, and are thereby connected to the link plate. The declined straight or curved centerline which runs the oblong hole to the oblong direction, extends at a given angle with respect to the radius of the link plate.

摘要： The object of this invention is to provide a nozzle adjustment mechanism for a variable-capacity turbine, which would have a connection between the connecting lever (1) to connect the nozzle drive component driven by the actuator to nozzle vane (2), and the edge of the nozzle shaft on the nozzle vane. The connecting hole (31;35) of the connecting lever (1) has a stopper surface (32;36;41) which is flat or curved. The connecting edge (33;37;42) of the nozzle shaft (02) also has a stopper surface (34;38) which is corresponding to the stopper surface of the connecting hole. When the connecting edge of the nozzle shaft goes into the connecting hole of the connecting lever, the stopper surface of the connecting edge is brought into contact with the stopper surface of the connecting hole contacting the non-circled surface each other. After the contact is made, then the fixing process will be applied to the connecting edge. The connector lever (1) and the connecting edge of the nozzle shaft (02) are thus effectively locked together in such a way that neither can rotate with respect to the other. The end of the nozzle shaft, in other words, prevents the shaft's rotation.
