Title:
ULTRA-HIGH SPEED MOTOR-DRIVEN AND POWER GENERATING TURBOCHARGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/184410
Kind Code:
A1
Abstract:
An ultra-high speed motor-driven and power generating turbocharging device, comprising a turbine machine (1), a compressor (2), a motor (3), two radial bearings (4) and a thrust bearing (5), the motor (3) comprising a rotor (31), a stator (32), an inner shaft (33), an outer shaft (34) and a motor housing (35), 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 rotor (31) being sleeved at a central portion of the inner shaft (33), the two radial bearings (4) being respectively sleeved on the outer shaft (34) located at left and right ends of the rotor (31), the thrust bearing (5) being sleeved on the outer shaft (34) at the right end, and being located on an outer end side of a right end radial bearing (4), the turbine machine (1) and the compressor (2) being respectively arranged at two ends of the inner shaft (33). The supercharging device implements an ultra-high speed stable operation in an air state, and with regard to identical power requirements, enables the size of the motor-driven and power generating turbocharging device to be significantly reduced for miniaturisation.
