Determination of loads transmitted by rolling elements in a roller bearing using capacitive probes: Finite element validation

摘要

In this paper, we present the numerical model of an experimental device for measuring the deformation of a bearing ring under radial force. Deflection is measured using a capacitive probe, consisting of a transducer yielding electrical signal from ring deformation. Next, contact force is calculated and linearity of the relationship between load and strain is checked. Thus, we measure the load transmitted by the rolling elements of rolling bearings. A numerical finite element model of the experimental setup is implemented to validate the experimental method and confirm the consistency of the measurement principle.
