After an introduction of the analytical expression of the flank profile curve of a double circular- arc gear tooth, by selecting preferable node distribution model, the program forming rule of the nodes on gear tooth is established, the node forming program CGFP1 and the tooth element dividing program CGFP2 are programed and tested.
By using these programs, the data file satisfying the requirement of the universal sofeware for the finite element analysis can be formed directly, therefore the efficiency for analyzing the strength and rigidity of the double circular-arc gear teeth can be remarkably improved.
The article gives a technical and theoretical description about the operation principle of gear cutting of circular gear, and analyses the control process of gear cutting depth which is technologically advanced in application.
The number of smaller gear teeth and normal module, helix angle and average tooth width are regarded as variable in circular gear driving design in this paper. The randomness and fuzziness which influence the gear driving system are all considered, and the smallest volume sum of the two circular gear is treated as the objective function. The mathematical model for optimal design of fuzzy reliability of a double circular gear driving system is established.
The automatic production of the double circular arc gear contact computation finite element model was realized used the corresponding computational procedure established by finite element software ANSYS in to inlay the language.
