An Analysis on High-Speed Gear Strength Based on Finite Element Method

Make a 3-D model finite element analysis on high-speed gear strength. Firstly, set up 3-D finite element model of three-teeth high-speed gear, and give a detailed explanation of how to choose flange thickness and number of teeth. Then analyse and calculate the gear contact strength and tooth bending strength of high-speed gear, and make a comparison with master gear strength. The calculation result shows that tooth bending strength of high-speed gear has increased by 5.31% and the gear contact strength has increased by 41.3％, compared to master gear, indicating that high-speed gear has a wide application.
