A commercial enclosed spur gearset has 22 teeth on the pinion and 60 teeth on the gear. The pressure angle is 20 and the overload factor Ko =1. The diametral pitch is 8 teeth/in and the face width is 5 in. The pinion speed is 1000 rev/min and its cycle life is to be 10° revolutions at a reliability R =0.50. The quality number is 5 and the tooth are crowned. The material is a through-hardened steel, grade 2, with Brinell hardnesses of 250 core and case of both gears. For a conservative design and bending stress design factor of 2, rate the pinion (power) for these conditions using the AGMA method.
