QUESTION 6 According to AGMA standards, bending stress numbers for different types of gear teeth are calculated differently. Please select the right formula for each type of gear teeth. Equation a: W.Pd K.K.K.Kak where W, = tangential force Pa = diametral pitch F = face width J = geometry factor K = overload factor for bending strength K, = size factor for bending strength K = load-distrubution factor for bending strength Kg = rim thickness factor K = dynamic factor for bending strength Equation b: W.P.K.K.KK. FJ where W, = tangential force Pa = diametral pitch F = face width J = geometry factor K, = overload factor for bending strength K = size factor for bending strength K = load-distrubution factor for bending strength K, = dynamic factor for bending strength For bevel gears, equation a should be used. For spur gears, equation b should be used. For helical gears, equation a should be used. For helical gears, equation b should be used. For spur gears, equation a should be used. For bevel gears, equation b should be used.
