What is shafting system in a wind turbine?
Typical Structure and mechanical model of shafting system in wind turbines The shafting system of the wind turbine has many structural types. A typical structure with two bearings (DTRB and CRB) and a main shaft is shown in Figure 1. The flange at the left side of the shaft is used to connect the hub and the shaft.
What is a wind turbine main shaft arrangement?
A wind turbine’s main shaft arrangement is part of a geared, hybrid, or direct drive design. Whatever the arrangement, it must withstand axial and radial loads and operate under harsh, continuously changing conditions. Wind turbine main shaft bearings spin at relatively low speeds of around 10 rpm. Also, they experience continually variable loads.
What is the main shaft bearing in a wind turbine?
The main shaft bearing serves as a key component in wind turbines, providing support to the rotor while withstanding the combined forces of radial rotation and axial wind thrust. The operational context of the main shaft bearing, however, exhibits substantial variations across different types of wind turbines.
How tribo-dynamic is a wind turbine main shaft sliding bearing system?
A 6-DOF tribo-dynamic model of main shaft sliding bearing system is established. Tribo-dynamic behaviors of wind turbine main shaft under wind loads is revealed. A bearing pad configuration that can effectively reduce friction and wear is proposed. Wind turbine (WT) main shaft bearings are currently dominated by rolling bearings.
