Separate coaxial loading device of turbocharger

The utility model discloses a separate coaxial loading device of turbocharger, which comprises a main separate loading bearing arranged in the bearing body of the turbocharger and a separate fitted bearing; the oil wedge surface of the main separate loading bearing and the oil wedge surface of the separate fitted bearing are oppositely arranged; a relatively closed supporting oil cavity is formed between the oil wedge surface of the main separate loading bearing and the oil wedge surface of the separate fitted bearing. The separate coaxial loading device of turbocharger effectively changes the loading mode of the thrust bearing of a normal supercharger, adjusts the loading structure of the thrust bearing into a relatively sealed environment to carry out, and solves the problems of invalidation and pool sealing performance of the sealing device of the existing supercharger; the main separate loading bearing sufficiently ensures the building of a supporting oil film and the reflowing of lubricating oil, thus fundamentally solving the sealing problem of the gas compressor end of the turbocharger and reducing the sealing requirement of the anaphase structure of the gas compressor end; the lubricating oil entering the sealing system of the gas compressor end is only 10 to 20 percent of the that of the original structure, and an ideal sealing effect can be realized only by employing a seal ring.
