Shaft & Wheel

What is the turbine rotor?

It is an important component of the turbocharger system. The turbocharger shaft, on which the compression wheel is located, converts the kinetic energy of exhaust gases into rotational mechanical energy. This process occurs because centrifugal forces act on the working blades attached to the crown of the rotor during rotation.

A characteristic feature of the turbocharger shaft is its complex structure, which includes:

- Central shaft;

- Crowns with blades.

Blades attached to the crown play a crucial role in energy conversion, creating circumferential forces that precisely direct the flow of exhaust gases. The turbocharger rotor needs to be made of materials with high strength and resistance to high temperatures, as this ensures its ability to withstand destructive centrifugal forces. This requirement is crucial for ensuring the durability and reliability of the turbine as a whole.

Why does the turbocharger rotor fail over time?

Due to intensive use, the turbocharger shaft can undergo significant wear, especially when operating at high speeds, often exceeding 250,000 revolutions per minute. The main causes of turbine rotor damage are the wear of sealing rings and bearings, leading to friction of the rotor blades against the turbine housing and shaft bearings. As a result, the turbine rotor may deform or even break, disrupting the normal operation of the turbocharger. Repairing these components is usually cheaper than replacing them with a new element, so it is important to quickly diagnose and address any malfunctions.

It is recommended to carry out repairs at an early stage of rotor wear to prevent destruction and maintain optimal turbocharger performance.

A key factor in the production of turbine rotors is the choice of material, which depends on the system's operating temperature. This indicator varies significantly depending on the type of engine - diesel or gasoline - and the type of vehicle - passenger car or truck. Special metal alloys resistant to high temperatures, vibrations, and pressure are used to produce various types of rotors.

Among the materials used for rotor production are:

- Nickel and chrome alloys. They are effective for operating at temperatures above 1000°C, suitable for high-temperature conditions of gasoline engines.

- Gray iron. Less commonly used due to temperature limitations up to 680°C.

- Heat-resistant austenitic steel. Designed for conditions with maximum temperatures of gasoline engines.
