Abstract

The invention relates to a turbine shaft structure of a radial supercharger and its forming process, including a turbine, a shaft and a self-locking ring. The turbine has internal threaded blind holes, light holes, ring grooves and guide chamfers. The shaft There are external threads, positioning shaft shoulders, optical shafts, and ring grooves. The self-locking ring is an elastic split ring and has guiding chamfers. By reasonably determining the structural dimensions of the turbine, shaft and self-locking ring, and processing the turbine, shaft and self-locking ring, and then assembling the turbine, shaft and self-locking ring together, a complete turbine shaft is formed. The invention can effectively solve the problem of turbine shaft connection when the turbocharger turbine adopts new materials such as ceramics and titanium-aluminum alloy, and can realize reliable connection of the turbocharger shaft, fully ensuring the connection strength and rigidity of the turbine shaft.

Description

technical field [0001] The invention belongs to the structural design field of a turbocharger, and in particular relates to a radial turbocharger turbine shaft structure and a forming process thereof. Background technique [0002] The turbocharger is one of the key components of the turbocharged engine, and the turbine shaft is the core component of the turbocharger, which is mainly connected by the turbine and the shaft. At present, the supercharger turbine is generally made of cast nickel-based superalloy K418 material (the material density is 8.0×10 3 kg / m 3 ), the shaft is made of 42CrMo alloy steel. For the turbocharger turbine made of K418 material and the shaft made of 42CrMo alloy steel, friction welding or electron beam welding technology can be used to realize the reliable connection between the turbine and the shaft to form the shaft of the turbine. However, due to the high density of the K418 alloy material, the moment of inertia of the turbine made of the K41...
