(a)Since values are same, unknown parameters will be same as those in problem 17.7
Diameter of Gear=200 mm Slant height of pitch cone:
L=sqrt(rp^2 + rg^2)=125 mm
Mean radius of pinion:
rm=rp-(b*sin(beta)*0.5)=60 mm
Pinion torque Mt=238 Nm
Tangential force at mean radius:
Ft=Mt/rm=3978 N
(b)Pinion thrust force:
Fp=Ft*((tand(phi_n)*sind(beta))/cosd(gamma) - (tand(gamma)*cosd(beta)))=-1124 N
(c)Gear thrust force:
Fg=Ft*((tand(phi_n)*cosd(beta))/cosd(gamma) - (tand(gamma)*sind(beta)))=2328 N
