Abstract:
A method for manufacturing constituent members of a variable throat-area mechanism of a variable-throat exhaust turbocharger for varying the blade angle of a plurality of nozzle vanes supported rotatably by a member in a turbine casing, wherein, for producing shaft members (32) to be inserted and fixed in through-holes (31) in a member with through-holes (31) among constituent members of said variable throat-area mechanism, wear-resistant material is welded on the upper surface of a steel plate to form cladding of a certain thickness thereon, said material being harder than the steel plate, and then crude shaft members are cut out from the clad plate.
