As a leading bearing manufacturer in China, TFL-bearings is committed to providing high-quality bearings for wind turbine applications. This section will explore various aspects of wind turbine bearings, including their classification, applications, selection factors, and important safety considerations.

TFL manufactures bearings for a variety of wind energy applications. All of our bearings are carefully designed to provide the high reliability and optimum performance essential to support the function of wind turbine installations' gears, generators, and blades. They are manufactured to withstand the variable loads, high torques, and high speeds found in wind turbines.

Introduction Of Wind Power Bearing Classification

The wind power conditions are harsh, and the reliability of the bearings is high, so the wind power bearings have a higher technical complexity than other applications.

Some-bearing-places-in-wind-turbine-nacelle.pngTaking the double-fed wind turbine as an example, the wind power bearings are mainly divided into two categories: pitch and yaw bearings and drive train bearings (main shaft, gearbox, and motor bearings). ), 1 yaw bearing, 3 pitch bearings, 1 set of generator bearings, and 1 gearbox bearings. For example, spherical roller bearings, single/dual row large diameter tapered roller bearings, cylindrical roller bearings are used for main shaft and gearbox bearings and rotary pivot bearings for yaw and pitch.

TFL Wind Power Bearing Process

The key technologies of wind power bearings are embodied in design, materials, anti-corrosion, and sealing. The key technologies of wind power bearings are mainly embodied in the design, materials, anti-corrosion, sealing, etc. The main shaft and gearbox bearings need to be processed with high precision. Bearings must also carry out high-precision machining; yaw and pitch bearings must solve the clearance design and grinding processing raceway technology.

Factors To Consider When Selecting Wind Turbine Bearings

Selecting the right wind turbine bearings ensures reliable and efficient operation. When choosing bearings for wind turbines, several factors must be considered. Firstly, load capacity is paramount as wind turbines are subjected to significant forces and moments. Bearings with high load capacity can withstand these forces without compromising performance. Reliability is another critical factor, as wind turbines are often installed in remote locations, making maintenance challenging. Choosing bearings from reputable manufacturers like TFL-bearings ensures long-lasting performance and reduces the risk of unexpected failures. Lubrication requirements, maintenance needs, and the ability to operate in harsh environmental conditions are also essential factors to consider when selecting wind turbine bearings.
