    • The invention provides a method and device of assembling and adjusting a variable capacity turbine, which simplifies assembling process resulting in reduction of man-hours and costs of assembling and adjustment, and makes it possible that the nozzle vane setting of the adjustable nozzle mechanism is done with high accuracy without 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 adjusted whenever necessary even after the turbine is assembled. The invention is characterized in that a plurality of nozzle vanes are temporarily encircled and bound with a binding member capable of binding/releasing such as belt, etc. in a state the vanes are perfectly closed with the vanes contacting to each other, then the nozzle pin fixed to each of the nozzle vanes and supported free of rotation in the nozzle mount is fixed by staking or the like to the lever plate constituting the connection part of the annular link mechanism with the vanes in the temporarily bound state.
    • 本发明提供一种组装和调节可变容量涡轮机的方法和装置,其简化了组装过程,从而减少了工时和组装和调节的成本,并且使得可调节喷嘴机构的喷嘴叶片设定成为可能 高精度,不受喷嘴叶片和环形连杆机构等构成部件的尺寸精度的影响,并且即使在涡轮组装后也可以调节可调喷嘴叶片机构。本发明的特征在于,多个喷嘴 叶片在叶片彼此接触的状态下被暂时环绕并且能够与叶片完全闭合的状态下与能够粘合/释放的捆扎件结合在一起,然后喷嘴销固定到每个喷嘴叶片并被支撑 在喷嘴座中没有旋转,通过铆钉等固定到构成连接点p的杆板上 环形连杆机构的技术,其中叶片处于暂时束缚状态。

    • A ratio of cross sectional area A of a scroll passage to a scroll radius R (A/R) can be increased without increasing the size of a turbine casing and with very simple construction. An exhaust turbine capacity can thus be increased, so that a variable-throat exhaust turbocharger in which the engine output can be increased results. The turbocharger has a nozzle throat area varying mechanism of which a nozzle assembly unit is composed. A plurality of nozzle vanes are supported rotatably by an annular nozzle mount and an annular nozzle plate is connected to the nozzle mount by a plurality of nozzle supports to sandwich the nozzle vanes. The nozzle plate is located in the scroll chamber by attaching the nozzle assembly unit to the turbine casing to allow the nozzle plate to form part of the inside sidewall face of the scroll chamber and a wall face of the annular flow passage.
    • 可以增加涡旋通道的横截面面积A与涡旋半径R(A / R)的比例,而不增加涡轮机壳体的尺寸并且结构非常简单。 因此,可以增加排气涡轮机容量,使得可以增加发动机输出的可变喉排气涡轮增压器。 涡轮增压器具有喷嘴喉部区域变化机构,其中组成喷嘴组件单元。 多个喷嘴叶片由环形喷嘴安装件可旋转地支撑,并且环形喷嘴板通过多个喷嘴支撑件连接到喷嘴座,以夹持喷嘴叶片。 喷嘴板通过将喷嘴组件单元附接到涡轮壳体而位于涡旋室中,以允许喷嘴板形成涡旋室的内侧壁面和环形流动通道的壁面的一部分。
