Resumen

This paper shows a methodology for adjusting the top-bottom contact stress ratio belonging to the outer raceway by combining the loads acting on the bearing by means the finite element method (FEM) and response surface methodology (RMS). A three-dimensional Finite Element (FE) model considering the material properties and geometry of a real tapered roller bearing was built. Subsequently, a design of experiments (DoE) study varying the input loads (preload, radial load, axial load and torque) was implemented. These input loads generated thought DoE were simulated in the FE model, and the contact stresses belonging to the outer raceway were obtained. A quadratic regression model for predicting the ratio between the contact stresses was formulated, and using the RMS method, a combination of input loads were found for adjusting a specific top-bottom contact stress ratio. © Springer International Publishing Switzerland 2015
