Description
Technical Field
The invention mainly relates to the field of turbochargers, in particular to a turbine shaft of a turbocharger.
Background
Turbocharging is a technique of driving an air compressor using exhaust gas generated by the operation of an internal combustion engine. Both of these functions, like the super charger, increase the air flow into the engine or boiler, thereby increasing the efficiency of the machine. Turbochargers are commonly used in automotive engines to boost the horsepower output of an internal combustion engine by utilizing the heat and flow of the exhaust gases. Because the supercharger is arranged on the exhaust side of the engine, the working temperature of the supercharger is very high, the rotating speed of the rotor of the supercharger is very high during working, which can reach hundreds of thousands of revolutions per minute, and the high rotating speed and temperature make common mechanical roller pins or ball bearings incapable of working for the rotor.
The turbine shaft is the heart portion of the turbocharger. Plays a crucial role in the whole work. In the turbocharging, a turbine shaft not only bears the power transmission, but also compresses fresh air and inputs the compressed air into an engine,
therefore, the turbine shaft is under high pressure and has severe working conditions, and a turbine shaft with high reliability needs to be designed.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides a turbine shaft of a turbocharger, which comprises a turbine shaft body 1, wherein the turbine shaft body 1 comprises an impeller mounting section 2, a limiting section 3, a first reinforcing section 4, a thread section 5, a second reinforcing section 6 and an output section 7 which are sequentially arranged from top to bottom;
and the middle end part sleeve of the second reinforcing section 6 is sequentially provided with a sealing ring 8 and a limiting ring 9 from top to bottom.
Preferably, the sealing ring 8 and the limiting ring 9 are arranged in a fitting mode.
Preferably, the stop collar 9 is welded to the second reinforcing section 6.
Preferably, the impeller mounting section 2 is provided with a clamping groove 10 along the side wall.
Preferably, the impeller mounting section 2, the limiting section 3, the first reinforcing section 4, the thread section 5, the second reinforcing section 6 and the output section 7 are integrally cast.
Preferably, the second reinforcing segment 6 has a length greater than the length of the first reinforcing segment 4.
The invention has the beneficial effects that: the turbine shaft body is formed by integrally casting the impeller mounting section, the limiting section, the first reinforcing section, the threaded section, the second reinforcing section and the output section, so that the welded part of the turbine shaft body is prevented from being broken in the use process,
