Intensity Comparative Analysis Based on Ideas Between Involute Gear and Double Involute Gear

Modeler and simulation modules in Ideas software are used to build the finite element models on involute gear and double involute gear with accurate tooth shape,and with the same design parameters and under the same loads,finite element contact analysis has been done.At last,the contact stress and bending stress on the two types gear transmission at the different meshing positions are solved out,and comparative analysis and study have been done.At the same time,that the ladder-shape tooth on the double involute gear how to influence contact stress and bending stress is emphatically analysed.All above offer the theoretical foundation that bring the double involute gear with ladder-shape tooth into the industry.
