The bending strength geometry factor J depends on the locationof the critical section and the tooth thickness at this section.The critical section is that in which the uncorrected bendingstress, given by Navier’sequation, is maximum and consequently itis defined by the point of tangency of the Lewis Parabola and thetooth profile. This point of tangency is usually placed over theroot fillet, but in some casts the tangency may occur at theinvolute. For these cases the methods descriied in literature fordetermining the AGMA J-factor are not suitable. This paper presentsthe condition for tangency at the involute and a method todetermine the J factor under this condition.
