Web15 dec. 2024 · There are three different types of interference can occur with internal gears: involute interference, trochoid interference, and trimming interference. ... It tends to happen when the difference between the numbers of teeth of the two gears is small. Equation 5 presents the condition for avoiding trochoidal interference. WebThis calculator conforms to the bending equations found in Wilfred Lewis's "Investigation of the Strength of Gear Teeth." Proceedings of the Engineers Club, Philadelphia, 1893. Material properties are based on data from the Society of Automotive Engineers', Technical Report on Fatigue Properties, SAE J1099, 2024.
