COMPRESSION DEVICE OF TURBO-MACHINE AND COMPRESSOR WHEEL THEREOF, COMBINING MALE SCREW PART FORMED TO BODY PART OF COMPRESSOR WHEEL AND MALE SCREW PART FORMED TO FRONT END OF SHAFT FOR DRIVING COMPRESSOR WHEEL VIA SLEEVE
PURPOSE: A compression device of a turbo-machine and a compressor wheel thereof are provided to reduce breakage although the compressor wheel is rotated at high rpm(revolution per minute). CONSTITUTION: A compression device of a turbo-machine has a compressor wheel male screw part integrally formed to a body part of a compressor wheel; a shaft male screw part formed to the front end of a shaft(23) for driving the compressor wheel; and a sleeve(49) having a compressor wheel-side female screw part to be combined to the compressor wheel male screw part, at one side and having a shaft-side female screw part to be combined to the shaft male screw part, at the other side. The compressor wheel male screw part and the shaft male screw part are interconnected via the sleeve.
