A commercial straight pinion has an 8 teeth / in. Diametric pitch, a 1.5 in. Face width, 16 teeth and a 20 ° pressure angle with full height teeth (calculating the Kv speed maker considering a milled profile). To be mated with a 50-tooth crown made of cast iron ASTM No. 50. With a tangential load of 382 lbf, estimate the safety factor of the transmission, based on the possibility of fatigue failure on the surface. (EP = 30Mpsi, vP = 0.292, EG = 14.5Mpsi, vG = 0.211, Sc = 83.8Ksi.)

Question #5 (20 pts) A pinion has 18 teeth and a diametral pitch of 9 teeth/in, a face width of 1,5 in sa pressure angle of 20° with full-depth teeth. The spur gear is made by the milling or emin required to transmit at least 11 hp horsepower with a corresponding speed and moderate applications. Which material is the best choice for the spu ones in Table 5 considering the maximum allowable bending stres (factor of safety, nd-2.5)? U quations...
27 Two 20° straight bevel gears have a diametral pitch of 4, and 24 and 48 teeth, respectively The tooth face width is 2 in. The pinion rotates at 1000 rev/min and transmits 50 hp. The shafts are at 90. Determine the components of the gear tooth force and show these on a sketch of the ge
