Embodiment 1
[0024] A kind of turbocharger, as shown in accompanying drawing 1, it comprises turbine rotor shaft assembly 5, intermediate body 6, compressed air impeller 17, turbine casing 9, pressure casing 10, air inlet 18, and pressure casing 1 integral system out of the diffuser plate 8, the turbine rotor shaft assembly 5 includes the rotor shaft, the turbine mounted on the rotor shaft and the compressor impeller 17, on the turbine rotor shaft assembly 5, a set of mutual Cooperating permanent magnet rings, the permanent magnet rings include two permanent magnet moving magnet rings and two permanent magnet static magnet rings, the two permanent magnet moving magnet rings 1 are arranged adjacent to each other, and the two are axially installed There is a magnetic sleeve 27, so that two permanent magnet moving magnet rings are positioned on the non-magnetic sleeve, and a permanent magnet static magnet ring is respectively arranged at the two ends of the permanent magnet dynamic magnet ring...
Embodiment 2
[0029] As shown in Figure 2, the difference between this embodiment and Implementation 1 is that a group of mutually matched permanent magnet rings installed between the turbine and the compressor impeller 17 is an axial polarity permanent magnet ring, which includes A permanent magnet moving magnet ring 1 and two permanent magnet static magnet rings 2, a permanent magnet static magnet ring 2 is arranged on both sides of the permanent magnet moving magnet ring 1, a permanent magnet moving magnet ring 1 and a permanent magnet static magnet ring 2 Cooperate to make the turbine end of the turbine rotor shaft assembly 5 suspend. The specific structure of the cooling method is different, mainly in that the cooling channel 13 makes the compressed air entering the vortex end bearing cavity flow back to the air inlet through the air duct.
Embodiment 3
[0031] As shown in Figure 3, the difference between the present embodiment and Implementation 1 is that a group of mutually matched permanent magnet rings installed between the turbine and the compressor impeller 17 is an axial polarity permanent magnet ring, which includes Two permanent magnet moving magnet rings 1 and one permanent magnet static magnet ring 2, the permanent magnet moving magnet ring 1 is located on both sides of the permanent magnet static magnet ring 2 and arranged axially along the rotor shaft.
