Digital visualization of time-varying local bearing contact recognition for non-orthogonal aviation spiral bevel gears

Abstract

Focusing on the time-varying meshing performance assessment and recognition, a new computer aided design/ computer aided manufacturing/ computer aided engineering (CAD/CAM/CAE) integration-based digital visualization of local bearing contact recognition is developed for non-orthogonal aviation spiral bevel gears. At first, universal tooth flank modeling and its CAD/CAM software development are developed to get a closed-form solution to the whole tooth flank points. Then, with applications of an improved digital kinematics arrangements, digital virtual assembly in CAD software is proposed for time-varying meshing simulation. To distinguish with the conventional loaded tooth contact analysis (LTCA), a digital deformation layering method is developed to show local bearing contact at each time-varying deformation layer. Where, accurate search for the loaded meshing points is developed by using the improved dichotomy iteration method. Moreover, instantaneous contact ellipse in software development is determined by chord intercept method. CAD/CAM/CAE integration-based digital visualization is performed by correlating with sensitive assembly error driven virtual simulation. Finally, the given numerical instance can verify the proposed method.
