Method for manufacturing variable-throat exhaust turbocharger and constituent members of variable throat-area mechanism |
摘要 |
The present invention provides a variable-throat exhaust turbocharger equipped with a variable-throat mechanism of which connection of constituent members can be achieved with a small number of man-hour and at low cost and which is stable in quality with firm connection of constituent members maintained under severe operating conditions. Among constituent members of the variable throat-area mechanism of the variable-throat exhaust turbocharger for varying the blade angle of a plurality of nozzle vanes supported rotatably by a members in a turbine casing, shaft members to be inserted and fixed in through-holes in a member with through-holes are produced by a method in which wear-resistant material is welded to form cladding of a certain thickness on the upper surface of a steel plate, said material being harder than the steel plate, and then crude shafts for forming drive pins are cut out from the clad plate.
