Unformatted text preview: the gear joint The finite element model was built on ANSYS software by a specific automatic parameterized program. Any conceivable classical cylindrical gear joint can be defined. Next, displacements are introduced in the centre of one wheel, with the other wheel fixed. The maximum Von Mises stress in the assembly is then measured. As we wanted to limit this one, UR is 1 at this limit. The FEM is made of brick elements for the wheels and contact elements between them. We made some optimisations in our model in order to minimise the computation time and obtain a satisfying accuracy. The model presented here is build automatically Figure 10 Meshing of a Wheel 338 S. Samper, J.-P. Petit and M. Giordano Figure 11 FEM of the Gear Joint In the figure 11 above, a rotation Rx and a translation Tx are performed and the resultant stresses may be observed. A wheel is set (the left one) and the other is moved step by step in the program. Three loops are needed to measure all the position sets of the gears. Each position provides a Von Mises maximum stress, the displacements torsor, an...
