More simulations of individual default have been done but not presented here. Figure 2D shows 20 simulations results with all random defaults (waves on actives surfaces, misalignment and displacement between pitch cones, errors on cumulative circular pitch, misalignment between actives surfaces and rotation axis). 4. CONCLUSION Statistical tolerance analysis seems to be the best tool to analyze the behavior of a gear box. We have applied this method to analyze the kinematic error in a bevel gear. We modelize the geometrical deviation and the geometrical surfaces; we use Tooth Contact Analyze tool to compute kinematic error at each position; and we analyse the impacts of 264 J. Bruyere et al. deviations on the kinematic error by Monte Carlo simulation. Therefore, numerous calculi allow to extract some pertinent information about the geome...
