Abstract

The invention discloses a full-floating bearing turbocharger rotor system. A turbine end full-floating bearing is mounted in a turbine end full-floating bearing mounting hole ina bearing body; a first anti-thrust end surface of the turbine end full-floating bearing makes contact with the bottom end surface of the turbine end full-floating bearing mounting hole; a pressure air end full-floating bearing is mounted in a pressure air end full-floating bearing mounting hole inthe bearing body; a second anti-thrust end surface of the pressure air end full-floating bearing makes contact with the bottom end surface of the pressure air end full-floating bearing mounting hole; a turbine rotor shaft is mounted in a bearing hole of the turbine end full-floating bearing and a bearing hole of the pressure air end full-floating bearing; a pressure air end sealing sleeve and an impeller are mounted at the other end of a shaft rod of the turbine rotor shaftin sequence, and are fixed on the shaft rod of the turbine rotor shaft through nuts; and a sealing ring is mounted in an annular sealing groove on the shaft rod of the turbine rotor shaft for sealing the turbine end of the bearing body. The shaft rod of the turbine rotor shaft and the inner wall of the first shaft rod hole form a first oil discharge cavity A, and the shaft rod of the turbine rotor shaft and the inner wall of the second shaft rod hole form a second oil discharge cavity B.

Description

technical field [0001] The invention relates to a turbocharger rotor system of an automobile engine, in particular to a turbocharger rotor system adopting a full floating bearing structure. Background technique [0002] Turbocharging is a technology that converts the residual energy in the exhaust gas of the engine into the effective power of the engine. This technology can not only significantly improve the power of the engine, reduce the fuel consumption of the engine, but also effectively reduce the harmful components in the exhaust gas emitted by the engine. , has the effects of high efficiency, energy saving and environmental protection. At the same time, this technology is also an important means of engine power recovery in plateau areas, so that the engine can adapt to the operating requirements of different altitudes. Therefore, turbocharger technology has become the development trend of engines. [0003] The rotor system is one of the important components of the t...
