<P>PROBLEM TO BE SOLVED: To provide an electric supercharge compressor with simplified constitution, easily assembled, reducing vibration and noise, and suppressing loss in motor output and a rotational shaft output while having a motor inverter. <P>SOLUTION: The electric supercharge compressor includes: an integrated housing 14 incorporating an electric motor 46 and the motor inverter 48; and a ball bearing 24 and damper sleeve structure 54 which are disposed on both sides of the electric motor 46. The damper sleeve structure 54 is constituted of a large-diameter sleeve 56, a spring guide 58, a coil spring 62, and a ball bearing 60. Clearances s1 are formed among the ball bearings 24, 60, a sleeve 34, and the large-diameter sleeve 56, and an inner ring 240 or an outer ring 242 of the ball bearing 24, 60 is supported by various kinds of support members disposed on both sides thereof. Elastic O-rings 38 are disposed on the outsides of the sleeve 34 and large-diameter sleeve 56 to elastically support them. <P>COPYRIGHT: (C)2013,JPO&INPIT |
