In the design of the gear strength, it is significant to find out the stress distribution of the gear root in advance as the gears are loaded. In the gear motion process with power transmission and speed change, the surface of the teeth will lead to the deformation and damage of the gears under the continuous or alternating bending stress. Furthermore, that will influence the efficiency of the gear power transmission.
This text mainly uses Finite Element Method to do the research and the analysis on the deformation and the stress distribution in the process the gears normally operate from arc of approach to arc of recess. Divide the arc of approach into 11 stages, and calculate the contact stress and distribution of bending stress of every stage.
In the beginning, build the mockup of the gears, grid the mockup, and execute elements and nodes of the optimization. Then set the boundary conditions, put the information to FEAST Finite Element Method software to process the gear contact, the bending stress analysis, and the deformation analysis.
Eventually, compare the results with data of related records to make sure the accuracy of Finite Element Method.
The research result simulates the meshing conditions of the gear pairs; in addition, it is the basic information for the subsequent researches that relate to develop and design the gears.
