Prediction and Experimental Validation of Aviation Floating Involute Spline

Based on the research wear mechanism of floating involute spline coupling, combined with traditional Archard equation, a prediction model aviation coupling was established. The transient simulation distances 0 mm, 0.3 and 0.6 mm carried out using Abaqus, accuracy theoretical verified by analyzing failure parts coupling. analysis results show that there is oxidation wear, adhesive abrasive other forms tooth surface Under influence distance calculation are closer to actual working situations. In addition, increasing distance, depth increases significantly, becomes larger along end. above study provides basis for designing maintaining aerospace couplings.
