“…Real-time data is employed in artificial intelligence modelling. Previously, wear damage was examined by few researchers [19,20]. To represent the damage (wear) induced by dry fretting and to characterise the dynamical frictional behaviour of the contact, an approach based on artificial neural networks was adopted [21,22] whereas in our research the wear analysis was carried out.…”

In the industry, ball bearings are the most widely used machine element. The ball materials may differ in various bearing applications. Wear of the ball and recess after a period of use is the most common cause of ball bearing failure. The present study aims to develop the artificial neural network model for assessing the wear of different ball bearing materials. A wear test method has been followed as suggested by the ASTM-G99 standard. The pin on disc apparatus was selected to conduct numerous trials. L9 array was considered to design the experiments. The factors considered for this study were load, time, and sliding speed. Based on the results obtained, ANN code was proposed to evaluate wear using numerous test parameters. The results obtained from the proposed model are nearly similar to experimental results, which would be evidence for the correctness of the model. The proposed neural network model can be used in numerous applications with given parameters.

Based on Hertz contact theory and load distribution, the formulas for contact stress cycle times, slip distance and wear depth measurements are derived, and the influences of load, curvature coefficient, roll body diameter and friction coefficient on the contact region wear depth and distributions are thoroughly analyzed. The results show that the wear depth is zero at the pure rolling point and the long half-axle terminals of contact ellipse, and reaches maximum value near by the long half-axle terminals of the contact ellipse, and further shows that the wear depth increases with increase of the load and friction coefficient, however decreases with increase of the curvature coefficient and roll body diameter.

“…Therefore, it is of great significance to study the stress and deformation of the bearing in the working process. [1,2,3] Xinglin Pei et al [4] established the finite element model of deep groove ball bearing with APDL parametric language and analyzed the bearing stress. Canjiang Yao et al [5] combined with Hertz theory and finite element method, analyzed the stress and deformation of rolling bearing in RV reducer under different working conditions.…”

Taking the cycloid pin gear reducer as the research object, the bearing force of the cycloid pin gear reducer shaft is calculated under different modification amount. Based on the Hertz theory, the contact stress and deformation of the bearing under different modification amounts are calculated. Based on the transmission principle of cycloid pin wheel reducer, the model of cycloid wheel and bearing is established and the finite element analysis is carried out. The analysis showed that the Hertz theoretical solution is consistent with the finite element analysis solution, which showed the correctness of the finite element results. The stress and deformation of the bearing obtained under different modification amounts of the cycloid wheel are not changed much. It can indicate that the cycloid wheel modification has no significant influence on the bearing force. Therefore, the research content of this paper has certain reference value for the design and optimization of cycloid pinwheel reducer.
