machine design ,spur gear

following data is given for a spur gear pair ade of steel and manufactured by shaping : Module=8mm;Centredistance=380mm; Permissible bending stress for pinion and gear =60N/mm2; Pinion speed =1500rpm; Gear speed =450rpm; Face width =10 Module ; Tooth system =20. full-depth involute ; Load application factor (or service factor )=15; Factor of safety =20 Assuming the velocity factor accounts for the dynamic load, calculate the rated power that the gear pair can transmit. Also suggest the surface hardness required. 10
