Figure 7: Solid model computer graphic of a perfectly conjugate
straight bevel gearset
An example straight bevel gearset computer model is shown in Figure 7. The
solid model in Figure 7 has been generated by using standard Gleason basic
settings, based on the generating gear approach and by applying a standard
®
Coniflex Plus cutter head as used on Phoenix bevel gear manufacturing ma-
chines. The Coniflex straight bevel gear calculation for conjugate contact has
to be conducted with a dish angle of 0° and no root angle correction
(DGammaM = 0.). The dish angle is creating the length crowning and the pro-
file crowning is commonly generated with a DGammaM (machine root angle
correction). With a dish angle of 0° and a DGammaM of 0° flank lead lines are
straight lines and the profile is a true Octoide (involute equivalent).
