steps. A 90 straight tooth Bevel gear drive having module (m) = 3.5 mm, zp = 21, z=148, b = 30 mm, So = 200 MPa for both pinion and gear. Pn = 20, np = 1460 rpm, wear strength factor (K) = 1.15 MPa, velocity factor C= 6/ (6+V) and hardness of tooth = 300 BHN. Considering the wear strength (Fw=1.5 Fa) Ffor the tooth, find out the safe power in kW and considering E = 210 GPa for both pinion and gear, check whether the supplied hardness is safe or not.
