Method and device for assembling and adjusting pivotable nozzle vanes of variable capacity turbine

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.
