A pair of bevel gear having a speed ratio of 4 has a 5 pitch at 14.5-degree involute. The pitch diameter of the pinion is 7-in. Find the addendum angle of the pinion (at right angle between shafts). The cone angle of pinion and the gear are 24 and 64-degrees respectively, find the speed ratio. The cone angle of pinion of a pair of bevel gear is 32-degree while 64-degree for the gear. If pinion turns 280 rpm, find the speed of the gear. A straight tooth bevel gear has a face width of 5-in and a pitch diameter of 15-in with a cone pitch angle of 40-degree. If the torque on the gear is 8200 in-lb., what is the tangential force on the gear? A 20-degree full depth straight tooth gear has a face width of 3.75-in and a pitch diameter of 13- in with cone pitch angle of 38-degree. Find the mean diameter.
