IMPELLER COMBINE STRUCTURE OF TURBO COMPRESSOR

摘要

PURPOSE: An impeller combine structure of a turbo compressor is provided to enhance the assembling efficiency by making easy the connection of a first and second impeller to both ends of a drive shaft installed on a turbo compressor. CONSTITUTION: A connection structure of a first and a second impeller on both ends of a drive shaft comprises:protrusively forming a supporting part(6) to hold the first and second impellers(2,3) tightly as connection nuts(4,5) on one position among the both ends and between the ends of the drive shaft installed on a turbo compressor; forming the diameter of the supporting part in hexangular with a consideration of balance when holding tightly.
