Turbocharger gas compressor sealing structure

The invention discloses a turbocharger gas compressor sealing structure which comprises a sealing sleeve, an oil seal cover, a thrust bearing, a bearing end cover, a rotor shaft, a gas compressor shell, a bearing body as well as an oil baffle, wherein a central hole is formed in the oil baffle; the oil baffle is mounted at the end, close to the oil seal cover, of the thrust bearing and is propped against the step surface in the inner hole of the gas compressor shell through the oil seal cover; a gap is formed between the central hole of the oil baffle and the outer circular surface of the sealing sleeve; an oil storage cavity A is formed between the oil baffle and the oil seal cover; an oil inlet cavity B is formed between the oil baffle and the thrust bearing. When the sealing cover rotates at a high speed, the lubricating oil on an oil throwing disc is thrown out by virtue of the centrifugal force, is splashed down to the oil baffle, and flows back to the oil cavity along with the oil baffle, so that the accumulation amount of the lubricating oil at one end of the oil seal cover is reduced, and the negative pressure resistance of the turbocharger gas compressor sealing structure is improved.
