Unformatted text preview: shown here. Figure 2A presents effect of the misalignment between rotation axis on the kinematic error. ε is the angle deviation and {A1, A2, A3} is the position vector from top cone of wheel 2 to top cone of pinion 1. As attempted, profiles of actives surfaces being spherical involute profile, kinematic error is independent form ε∆, for ε∆∈[-0.02 , 0.02]. Each value of A1, A2 and A3 is chosen with uniform random manner. For 20 shots, results are shown in figure A. Kinematic error is on the inner interval [-7.10-4 , 5.5.10-3]. The program is replicated 1010 times and the kinematic error amplitude is stored. We count them number in each class of 10-4 radian. The result is the probability function of the kinematic error amplitude (figure 2B). During manufacturing, misalignments could occur between active surfaces and rotation axis. This default is simulated by an angle between axis and a vector of translation. This parameters can take any value with a uniform distribution, in interval [- Statistical Tolerance Analysis of...
