The principal disadvantage of conformal gearing is its acute sensitivity to center-distance error. An improved type of all-addendum conformal gearing is disclosed in which the concave tooth is much more flexible than the convex tooth, so that if the gears are mounted at too great a center-distance, the tendency of the tooth load to be exerted on the tip of the concave tooth is offset by tooth flexure which shifts the arc center of the concave profile a considerable distance toward the axis of the gear with convex teeth. This increases the pressure angle sufficiently to prevent overloading of the tip of the concave tooth. |
