【 摘 要 】

The article deals with analysing the stiffness of a special type of bearings called slewing bearings. The purpose of the analysis is to examine the stiffness of the bearing steel. This type of bearings is most often designed for operation in which the rolling elements and hence the rings themselves are loaded in the axial direction. However, the aim of the work is not only to examine the stiffness but to identify possible ways that would favourably affect the stiffness, achieving the maximum lifetime or the maximum hours of operation. Stiffness measurements will be performed in the Ansys Workbench calculation program. On the basis of the measured values, manual calculation will be performed on the basis of which possible inaccuracies that arise from the bearing production itself will be corrected.
