Part I The shaft rotating at 240 rpm carries a spur gear D having 48 teeth with a Pd 6. The teeth are of the 20 degrees, full depth, involute form. The gear receives 15 hp from pinion Q located as shown. Compute the torque delivered to the shaft and the tangential and radial forces exerted on the shaft by the gear Resolve the tangential and radial forces into their horizonal and vertical components and determine the net force acting...

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...
