Question

A pair of helical gears are to transmit $15\text{ kw}$. The teeth are $20^\circ$ stub in diametric plane and have a helix angle of $45^\circ$. The pinion runs at $10000\text{ r.p.m.}$ and has $80\text{ mm}$ pitch diameter. The gear has $320\text{ mm}$ pitch diameter. If the gears are made of cast steel having allowable static strength of $100\text{ MPa}$; determine a suitable module and face width from static strength considerations and check the gears for wear, give $\sigma_{es} = 618\text{ MPa}$.
