The present paper describes an experimental setup and an associated calculation procedure in order to measure and predict the electric impedance of rolling bearings, in order to use it as a sensor model for measuring bearing loads. Based on the state of research, relevant influences on the electric impedance of a rolling bearing are not taken into account in the models known to the author. These influencing factors are added by an approach which takes unloaded rolling elements and the undeflected area of loaded rolling elements into account. A comparison between experimental results and the adapted theory shows that the consideration of unloaded rolling elements in the bearing model improves the predictions made compared to the state of the art. Nevertheless a difference between measurement and calculation remains, which is addressed by pointing out approaches to further reduce this discrepancy.

本文描述了一种实验装置和相关的计算程序，以便测量和预测滚动轴承的电阻抗，以便将其用作测量轴承载荷的传感器模型。基于研究现状，在作者已知的模型中未考虑对滚动轴承电阻抗的相关影响。这些影响因素是通过考虑未加载的滚动元件和加载的滚动元件的未偏转面积的方法来添加的。实验结果和适应性理论之间的比较表明，与现有技术相比，在轴承模型中考虑空载滚动元件可以改善所做的预测。不过，衡量与计算之间仍然存在差异，
