A pinion and gear pair is used to transmit a power of 5000 W. The teeth numbers of pinion and gear are 20 and 50. The module is 5 mm, the pressure angle is 20o and the face width is 45 mm. The rotational speed of pinion is 300 rev/min. Both the pinion and the gear material are Nitralloy 135 Grade2 with a hardness of 277 Brinell. The quality standard number Qv is 5 and installation is open gearing quality. Find the AGMA bending and contact stresses and the corresponding factors of safety for a pinion life of 109 cycles and a reliability of 0.98
