5) A par of years with a 20° full depth involute teeth trausmits 0.50 hp while the pinion rotates at 3450 rpm. The diametral pitch is 32, and the quality number is A7. The pinion has 24 teeth and the gear has 120 teeth. I The face width is 0.50 in. The Input power is from an electric motor, and the drive is for a small machine tool. The drive is a precision enclosed gear unit. a) Compute the bending...
A speed reducer has 20° full-depth teeth with a diametral pitch of 4 teeth/in, a face width of 3.25 inches, and with the pinion having 22 teeth and the gear having 60 teeth. The pinion is driven by a 40 HP motor rotating with a shaft speed of 1145 rpm. The pinion is designed to last for 5 years operating around the clock. The gears are manufactured using 4340 through-hardened grade 1 steel, both heat treated to 250 HB using...
Two 20° involute full depth spur gears are used to transmit the power and speeds shown. The material for both pinion and gear is specified as through- hardened steel tempered to 300 BHN surface hardness. Both pinion and gear are precision cut for "very accurate” gearing. For a factor of safety of 2 and assuming a diametral pitch, Pof 9. specify face widths of the pinion and gear using only the AGMA bending fatigue analysis. State all assumptions used to...
