An ultra-high speed turbocharger, comprising a turbine machine (1), a compressor (2), a rotary shaft (3), two radial bearings (4), a thrust bearing (5) and a main housing (6), the radial bearings (4) being groove-type dynamic pressure gas radial bearings, the thrust bearing (5) being a mixed-type dynamic pressure gas thrust bearing, the main housing (6) being sleeved at a central portion of the rotary shaft (3), the two radial bearings (4) being respectively sleeved on the rotary shaft (3) within the main housing (6), the thrust bearing (5) being sleeved on the rotary shaft (3) between the main housing (6) and a pressure wheel (21). The ultra-high speed turbocharger implements an ultra-high speed stable operation in an air state, and with regard to identical power requirements, enables the size of the turbocharger to be significantly reduced for miniaturisation. |
