Numerical - Dynamic load on single stage bevel gear box

Q.  A bevel gear consists of steel pinion and cast iron gear having pitch line velocity of 10 m/s. The maximum tangential force acting on the gear is 1500 N and face width is 40 mm. What is the dynamic load acting on this single stage bevel gear box if sum of errors on meshing teeth is 10 x 10-3 N/mm? (Use Buckingham's equation)

    Given: V = 10 m/s, Ft = 1500 N, b = 40 mm, e = 10 x 10-3 N/mm

    Dynamic load (Fd) = [21 V (bC + Ftmax)] / [21 V+(√bC + Ftmax)]

    For bevel gear of steel pinion and cast iron gear, C = 10000 e = 10000 x 10 x 10-3 = 100 N/mm

    Substituting the given values we get,

    Dynamic load = 4064.58 N
