Problems solved by technology

[0002] The traditional turbocharger is roasted by high-temperature exhaust gas, and the working environment is harsh. Therefore, its lubrication system is prone to sintering failures. At the same time, the high temperature also causes the output gas temperature to be too high. It cannot be directly used by the engine, and it needs a huge intercooling system. To dissipate heat for it, at the same time, the turbine body also needs to have oil passages, water passages and their respective interfaces, so the structure of the part body is complicated and the manufacturing cost is high

Abstract

The invention relates to the technical field of internal combustion engines, in particular to a high-performance long-acting supercharger. A rotary shaft is matched with a bearing seat through a thick-film bearing. Annular oil grooves are formed in the inner and outer side walls of a thick film bearing body. Symmetrical oil gathering grooves evenly distributed in the circumferential direction areformed in the annular oil grooves. The rotation direction of the oil gathering groove in the inner side wall is the same as the working rotation direction. The rotation direction of the oil gatheringgroove in the outer side wall is opposite to the working rotation direction. Openings are formed in the ends, connected with the annular oil grooves, of the oil gathering grooves, and the other ends are closed. A main oil channel communicating with a high pressure oil channel of the bearing seat is formed in an air compression cavity. The main oil channel is the fifth channel along with the shapeof the air compression cavity. The main oil channel is further provided with a first channel and a secondary oil channel which communicate with the high pressure oil channel correspondingly. The secondary oil channel and the high pressure oil channel are jointly connected to an oil pan through a communicating part. A lubrication system is redesigned, heat dissipation and coking problems of a traditional turbocharger are solved, and the service life of the supercharger is prolonged while supercharging performance is improved.
