Abstract:
This paper presents an analytical -numerical model to analyze the static behavior of the bearing assembly support with double row ball bearings with angular contact for agricultural mechanization. Bearing analytical model was developed based on John Harris's quasi-static equilibrium equations and Hertz's contact load. Based on the analytical model contact loads, change the contact angle and stiffness for each position of the ball are determinate. Results obtained by analytical models are applied to the 3D finite element model of the bearing assembly. The apply of the models are presented an analysis of the influence of the external load on the static and dynamic load capacity, stress and bearing life for different values of contact angle and the distance between the bearing raceways. The research in this paper show that the contact angle significantly affects the capacity and bearing life, while the distance between the bearing raceways affect the change of the stress of the entire bearing assembly for agricultural mechanization.
