Turbocharger Shaft Component

Turbocharger Shaft Component

The turbocharger shaft, as one of the key components inside the turbocharger, is a precision part that operates at high speeds and extreme temperatures. The manufacturing process is complex, requiring high precision and material selection. It is the core technology of turbocharger manufacturing, ensuring reliable and quiet operation at high speeds.

The turbocharger shaft can be made of three different superalloy materials to suit the operating conditions of the turbocharger. It consists of a high-grade steel shaft and a turbine wheel. The turbine wheel is electron beam welded onto the shaft, creating an extremely strong and reliable weld joint.

Each turbocharger shaft is specially designed, with the turbine wheel featuring a complex aerodynamic shape. Exhaust gases enter through the turbine wheel blades' guide vanes, maximizing energy transfer through rotation. The contour profile strictly matches the shape of the turbocharger housing, with very small clearances. Finally, the exhaust gases are expelled from the turbocharger through the outlet diffuser into the exhaust system.
