Helical gear set has 20 degree normal pressure angle, 18 degree
helix angle, 30mm face width, 4mm module. Tooth surface hardness is
240 BHN for pinion and 280 BHN for gear. Ultimate tensile strength
is given as 750 MPa for pinion and 600 MPa for gear. Calculate the
minimum safety factor of gear set if pinion with 32 teeth is
driving helical gear with 80 teeth. Calculate axial contact
transverse (profile) contact ratio and total contact ratio for gear
set.
