Design of Radial Loading Test Bench for Main Bearing of Wind Turbine

According to the target requirements, this paper designs and introduces a bearing radial loading test bench. It can simulate the situation when the outdoor fan blade encounters lateral wind and cause the main bearing to have partial load. At the same time, according to the different types of bearings, the test bench is also equipped with corresponding expansion sleeves to match the bearings for testing. The monitoring of main bearing running state of wind turbine is realized according to the changes of bolt pre-tightening force, which provides a reference for the experimental study of wind turbine shaft bearing running state monitoring under different working conditions.
