Comparative study by FEM of the stress and strain in the worm gear reverse tapered pinion for different materials

This paper presents a comparative study done by FEM of the state of stresses and strains of a worm face gear with reverse tapered pinion, worm wheel which is made of different materials: ERTACETAL C, BRONZE and CAST IRON. The simulation of real physical phenomena engagement of screw-worm wheel is a sensitive issue that raises many problems. One of the methods allowing achievement of precise geometry of the structure would be considered as complete, is FEM. Considering the geometrical complexity of the analyzed structure, proceed to a simplification of the phenomenon of contact between worm-worm wheels. Thus, for a correct interpretation of the studied phenomenon, corresponding geometric data from a section plane of worm-worm wheel gear is an analysis of the action momentary contact between the worm-worm wheels. The theoretical evaluations are confirmed by the results obtained from the analysis and interpretation of experimental tests of the worm face gear with reverse tapered pinion studied
