Turbocharger with bearing self-returning function

Abstract

The invention discloses a turbocharger with a bearing self-returning function. The turbocharger comprises a supercharger turbine end shell, a compressor end shell, a middle body, a pressing end sealing body, a landing leg support and a rotor penetrating through the supercharger turbine end shell and the compressor end shell and further comprises a radial bearing and a bearing shell with a gravitycenter not coinciding with a geometric center. The radial bearing is arranged on the periphery of the rotor, and the bearing shell is arranged on the periphery of the radial bearing. According to theturbocharger with the bearing self-returning function, the radial bearing is arranged on the periphery of the rotor, the bearing shell with the gravity center not coinciding with the geometric centeris arranged on the periphery of the radial bearing, the problem that the conventional movement locus of a rotor system unpredictably changes, and scratching, chamber sweeping and even burning damage and blockage of the rotor and the bearing and shell pieces are caused by the unpredictable change very easily is solved.

Description

technical field [0001] The invention relates to the technical field of turbochargers, in particular to a turbocharger with a bearing automatic return function. Background technique [0002] With the continuous promotion and development of diesel engines in the marine field, diesel engine turbocharger products are also playing an increasingly important role in the marine field. [0003] Different from land use or rail transportation, diesel engine turbochargers in marine use will swing irregularly with the wind and waves together with the diesel engine and the hull during actual use. [0004] This kind of swing is likely to cause scraping, sweeping, or even burning and solidification of the rotor, bearings, and shell parts, which in turn reduces the working capacity of the diesel engine and ship power system and increases the safety risk. Since such damage is usually irreversible, it is necessary to replace the entire turbocharger with new parts and components to restore the...

AI Technical Summary

Problems solved by technology

[0004] This kind of swing will easily lead to scratching, sweeping and even burning of rotors, bearings, and shell parts, which will reduce the working capacity of diesel engines and ship power systems and increase safety risks.

Since such damage is usually irreversible, it is necessary to replace the whole with new components to restore the work of the turbocharger, which seriously affects the self-sustaining force and seaworthiness of ships operating in open seas for a long time
