A spur pinion and gear pair is used to transmit a power of 25 kW. The teeth number of pinion is 18. The distance between the centers of the pinion and the gear is 144 mm. The sped ratio is 3, the
pressure angle is 20o and the face width is 50 mm. The rotational speed of pinion is 1200 rev/min. The
pinion and the gear material are through hardened Grade-2 with a hardness of 300 Brinell. The quality
standard number Qv is 7 and installation is open gearing quality. The power source and the driven
machine are subjected to medium and moderate shocks, respectively. Find the AGMA bending and
contact stresses and the corresponding factors of safety for a pinion life of 107 cycles and a reliability of
0.99.
