Abstract

Rolling bearing cages perform a very high-frequency movement
within their cage pocket clearance compared to the rotational speed under
certain operating conditions. This is often accompanied by higher elastic
deformation and noise. An unstable cage movement causes high contact
forces and reduces the performance of the bearing used. The presentation
gives an overview of the essential properties of the unstable cage
movement derived by multi-body simulations. Relations between the cage
movement and the boundary conditions in the simulation such as
coefficient of friction and load are identified. Based on the simulation
results, an index is defined that allows the calculated or measured cage
movement to be classified into different types and objectively evaluates the
cage dynamics. A comparison of the calculated and experimentally
measured cage dynamics for different load cases is presented to validate
the simulation results.
