a pair of involute tooth gears of 20 ° to full depth transmit 18kw, from a turning pinion to 1200 r.p.m. even an output shaft that must rotate at 320 r.p.m + \ - 5%. These elements are part of the transmission of a milling machine. Design the gear and the wheel having as design criteria the effort to flex and bite, if you must guarantee the operation during 5 years of continuous work. The design must have a reliability...

Spur gear analysis
A speed-reducer has 200 full-depth teeth, and the single reduction spur-gear gearset has 22 and 60 teeth. The diametral pitch is 4 teeth/in and the face width is 3-1/4 in. The pinion shaft speed is 1145 rpm. The life goal of 5 year 24 hours per day service is about 3(10 9) pinion revolutions. The absolute value of the pitch variation is such that the transmission accuracy level number is 9. The materials are 4340...
