Problems solved by technology

[0004] However, when new materials such as titanium-aluminum alloy and ceramics are used to manufacture supercharger turbine impellers, due to the high hardness of materials such as titanium-aluminum alloy and ceramics, as well as changes in the overall stiffness and mass distribution characteristics of the turbine shaft, it is difficult to process turbine wheels using existing processes. The sealing ring groove of the rotating shaft is easy to cause the sealing ring groove to crack, and the surface quality of the sealing ring groove cannot be guaranteed, which seriously affects the sealing effect of the turbine end of the turbocharger. At the same time, the position deviation of the workpiece during the processing will also seriously affect the sealing The performance of the ring groove affects the installation of the sealing ring and the sealing effect after installation

Description

technical field [0001] The invention relates to the technical field of sealing ring groove processing, in particular to a processing method for a supercharger sealing ring groove. Background technique [0002] The turbine shaft is one of the key components of a turbocharger for vehicles, and is usually composed of a turbine wheel and a shaft. [0003] In order to reduce the moment of inertia of the turbocharger rotor, the supercharger turbine impeller can be made of materials such as titanium aluminum alloy and ceramics with high specific strength. For example, the density of titanium-aluminum alloy material is only 3.9×103kg / m3, and at the same time it has good high-temperature performance and oxidation resistance, and has a large elastic modulus. The supercharger turbine impeller made of titanium-aluminum alloy can greatly reduce Moment of inertia of the turbocharger. [0004] However, when new materials such as titanium-aluminum alloy and ceramics are used to manufactur...
