Interference between profiles – graphical algorithm in catia by the method of generating trajectories family
A shortcoming of generation using rolling method is given by the interference of profiles due to the generation of trajectories of the discontinuities on the composed profiles, as happens with the majority of profiles used in technical applications. An analysis of an interference process in case of a gear worm is proposed in this paper. The problem is approached as a gear between the toothed wheel and the rack (the worm’s axial section), using the complementary theorem of the generation of trajectories. An analytical support and a graphical algorithm developed in CATIA design environment are presented. A numerical example calculated using the graphical methodology is also presented.
