Tribology is the science and engineering of interacting surfaces in relative motion. It includes the study and application of the principles of friction, lubrication and wear. Objective: The aim of this study is to develop a mathematical model to predict the variation of pressure between the slipper bearing surfaces when one of the surfaces is nonlinear. Methods: The model evaluates the power requirement for transmission of a prescribed load for a given relative velocity between the nonlinear slipper bearing surfaces. Results: A relative comparison between linear and nonlinear bearing surfaces is provided. The model results are in agreement with data from the literature. Further it has shown that the power transmission for nonlinear slipper bearings, depend on the profile index (n) and Convergence ratio (f). Conclusion: A design criterion is put forward to specify the slipper surface for the reasonable power transmission.
