Contact ratio is always
WebThe contact ratio will be the length of this segment divided by the \length" of a single tooth. This is why the contact ratio is called a ratio{because it is calculated as the ratio of two lengths. Nevertheless, it is also the average number of teeth in engagement between meshing gears. WebMay 19, 2024 · Total contact ratio is the sum of transverse contact ratio and overlap ratio, and theoretically total contact ratio must be 1.0 or higher for rotation at constant speed on the driven side. Although total contact ratio is greater than one (total contact ratio 2.6), noise increases due to the following reasons.
