Steam turbine bearings: the key to stably supporting the rotor

In the steam turbine, a complex power machine, bearings are one of the core components, and their stability and reliability are crucial to the operation of the entire unit. Through its unique structural design, Turbine Bearings provide solid support for the rotor, ensuring that it remains stable during high-speed rotation and avoids excessive vibration or displacement due to weight or unbalanced mass.

Turbine Bearings are mainly divided into two types: thrust bearings and support bearings. Among them, support bearings play a crucial role in steam turbines. The main responsibility of the support bearing is to bear the weight of the rotor and also to withstand the centrifugal force caused by the unbalanced mass of the rotor. This unbalanced mass can be caused by factors such as small errors in the manufacturing process, inhomogeneities in the rotor material, or thermal expansion during operation.

To effectively meet these challenges, the support bearings have a carefully designed structure. This structure not only has sufficient strength and stiffness to withstand the weight and dynamic load of the rotor, but also ensures stability and reliability under long-term, high-load operating conditions. In addition, support bearings also need to have good lubrication properties to reduce friction between the journal and the bearing bush, reduce energy consumption and wear, and extend the service life of the bearing.

During the operation of the steam turbine, the support bearing provides stable support for the rotor through its unique structural design. This allows the rotor to remain stable when rotating at high speeds, avoiding performance degradation or equipment damage due to vibration or displacement. At the same time, the support bearing can also effectively transmit the torque and power of the rotor, ensuring the normal operation and efficient output of the steam turbine.

Turbine Bearings provide stable support for the rotor through its unique structural design, ensuring the normal operation and efficient output of the steam turbine. During the design and manufacturing process of steam turbines, full attention should be paid to the role of bearings, appropriate bearing types and structures should be selected, and lubrication and maintenance should be strengthened to improve the reliability and service life of steam turbines.
