TRANSMISSION Ch 2 page 256 EXAMPLE 1: DEDENDUM TOOTH POSITION The contact pattern on the convex and concave flank is too close to the root, although more than 50% of the flank in h-direction is covered. An adjustment is necessary! Feature: On the convex flank the contact pattern is tangent to the toe, on the concave flank it is tangent to the heel. Adjustment: Install thinner pinion shim! The contact pattern is in the flank without bridging and a minimum of 50% of the flank in h-direction is covered. The example shows a relatively small contact pattern. However, the contact pattern is tangent to the tooth centerline and would cover the flank optimally in case of a higher load (see sketch).
