An acceptable contact pattern is centralized between
toe and heel along the length of gear teeth.
Figure 5.15.
In cases where it is not possible to get a good
contact pattern, the contact pattern shown in
Figure 5.15 is acceptable. If the acceptable contact
pattern is not achieved, change the ring gear and
pinion set.
Figure 5.16 indicates a good contact pattern. It is
toward the toe and centralized between the top and
bottom of the gear teeth.
