COMPRESSOR WHEEL ASSEMBLY INCLUDING COMPRESSOR MOUNTED TO ROTATING SHAFT

摘要

PURPOSE: A compressor wheel assembly is provided to make a shaft bore have a diameter suitable for exact mass production and to efficiently reduce the diameter of the bore correspondently to the diameter of a shaft. CONSTITUTION: A compressor wheel assembly includes a compressor wheel(7) mounted to a rotating shaft(8) and a cylindrical sleeve(22). The rotating shaft is extended through a bore(21) arranged along an axis of rotation of the compressor wheel. The bore has the internal diameter larger than the external diameter of the shaft part passing through the compressor wheel. The cylindrical sleeve is concentrically arranged around the shaft between the outside of the shaft and the inside of the bore.
