Reduction of bearing damage in the drive train of wind turbines (WT-Bearing Center.NRW)

Project objective

The approach of the project WT-Bearing Center.NRW is divided into four phases. In the first phase »Hardware Implementation« the two prototype test rigs will be constructed and put into operation. Therefore a list of requirements for the development of the test benches will be created and the variables that influence the service life of the bearings will be recorded and quantified. The second phase »Test Procedures HALT & WEC« includes the development of accelerated life test procedures under multiaxial loads. Based on this, special test procedures for the reproduction of WEC and the approval of roller bearings will be elaborated. The developed test procedures will be applied and validated in the third phase »Validation« by 25 tests on the HSS-bearing test rig and 15 tests on the planetary bearing test rig. In addition, simulation models will be created to calculate the influence of the test parameters on the local loads of the examined bearings in the phase »Optimization«. In this phase the test rigs and test parameters will be optimized. The test rigs and test procedures will not only contribute to the safety and efficiency of energy supply, but also strengthen and expand the pioneering role of North Rhine-Westphalia in the field of wind turbine technology.

Expected outcome

Novel testing methods for wind turbine roller bearings.
