Description

Technical Field

[0001] The utility model relates to the technical field of turbocharger rotating shafts, in particular to a rotating shaft component of a turbocharger. Background Art

[0002] A turbocharger is actually an air compressor that increases the intake volume by compressing air. It uses the inertial force of the exhaust gas discharged by the engine to drive the turbine in the turbine chamber. The turbine in turn drives the coaxial impeller, which pressurizes the air sent from the air filter pipe and pressurizes it into the cylinder. When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase synchronously, and the impeller compresses more air into the cylinder. The increase in air pressure and density can burn more fuel. By increasing the fuel amount and adjusting the engine speed accordingly, the engine's output power can be increased.

[0003] Currently, most shaft components on the market are connected to turbochargers by welding. However, after long-term use, the shaft components of the turbocharger are easily damaged, and workers are unable to quickly install or disassemble the shaft components to the turbocharger, causing inconvenience to the workers.

[0004] To this end, we propose a rotating shaft component of a turbocharger. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rotating shaft component of a turbocharger comprises a turbine and a rotating shaft component body, wherein a connecting assembly capable of being detached from each other is provided between the turbine and the rotating shaft component body.

[0007] The connection assembly includes a fixing seat installed on one side of the turbine, an inner wall of the fixing seat is provided with a first thread, and one end of the fixing seat is provided with a groove.

[0008] Among them, a sealing ring is placed inside the groove, a tight groove is opened on one side of the sealing ring, a connecting seat is movably connected inside the fixing seat, and a positioning thread groove is opened on the outside of the connecting seat.

[0009] The outer wall of the connecting seat is provided with a second thread, and a limiting plate is installed at one end of the connecting seat, and the diameter of the limiting plate is larger than the diameter of the connecting seat.

[0010] Wherein, a tight plate is installed on one side of the limiting plate, and the tight plate is located in the tight groove.

[0011] A mounting tube is fixedly mounted on one side of the fixing seat, and a connecting rod is movably connected inside the mounting tube.

[0012] One end of the connecting rod is fixedly installed with a bolt, and the other end of the connecting rod passes through and extends to the top of the installation tube and is fixedly installed with an anti-slip handle.

[0013] The utility model has at least the following beneficial effects:
