4 Frequently Asked Questions about “Wind turbine generator bearing dimensions - RRR Renewable Projects (SA)”
How long do wind turbine bearings last?
For the Environment... forces of Nature into a stable supply of electric power. achieve an operation life of 25 years or more. Main shaft bearings of various types and sizes are required to support the diverse wind turbine designs and the ever increasing size of both onshore and offshore wind turbines.
What is a main bearing in a power generator?
A main bearing must efficiently transmit the torque generated by wind power to the power generator, minimizing energy loss. It must also safely withstand high forces and tilting moments. Thus, the main bearing is the central component of the drive train concept.
Why do wind turbines need rolling bearings?
Whether for the main drive stage or other components, our broad range of rolling bearing products deliver reliable and sustainable operating life across wind turbine applications. The rotor induces high axial and radial loads in the main bearings, which occur both statically and dynamically.
What type of bearings do wind turbines use?
Spherical roller bearings used in the 3-point and 4-point drivetrains, or cylindrical and tapered roller bearings used in the 4-point drivetrain, are particularly well-suited for this application. A variety of gearbox arrangements have been implemented for wind turbines in recent years.
