A pair of helical gears consist of a 20 teeth pinion meshing with a 100 teeth gear. The pinion rotates at
Ta
720 r.p.m. The normal pressure angle is 20° while the helix angle is 25°. The face width is 40 mm and
the normal module is 4 mm. The pinion as well as gear are made of steel having ultimate strength of
600 MPa and heat treated to a surface hardness of 300 B.H.N. The service factor and factor of safety
are 1.5 and 2 respectively. Assume that the velocity factor accounts for the dynamic load and calculate
the power transmitting capacity of the gears.
