Method and device for assembling and adjusting variable capacity turbine

Abstract

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.
