Three idlers of 28 T , 26 T and 26 T are introduced between the 34 T pinion withaturning speed of 400 rpm driving a final 96T gear. A. What would be the final speedof the driven gear and its direction relative to the driving gear rotation? B. computecompute the center distance between driving and driven gears if the module is 5

Qestion-3: For the gear train shown identify which of the rack-gear will move faster (Gear-COR Gear-R) and how many modulos are powible? C and R: Rack Gears Dand B: Compound Gears R

4- Find the gearing ratio for the given compound gears shown in figure 10. 5- Given that the torque (t) of the driver gear is (40+x) N.m, find the torque of the green gear. (x is the last digit of your ID) (M) rrrrv Figure 10 Figure 11 D Error

1. The figure below is a spur gear train drive and gear 2 is the inlet of the gear train. It transfers 12 kw of power at 1200 rpm. Gear 3 and 4 have 60 and 20 teeth respectively and are made with 20° pressure and full-depth teeth. The desired speed for the output shaft is 32 rpm. a. Find the minimum number tooth on gear 2 to obtain 32 rpm at the output and confirm its validation for interference-free power transfer. b. Find the speed ratio at each gear set using the results obtained at "a"(above). c. Determine the rotational speed of each gear (n2, n3, n4, and n5) using the results obtained at "a"(above). d. Find the torque of each shaft (Tin, Te, Tout) assuming that there is no frictional loss during the power transfer. e. Determine the radial, tangential and total forces transmitted at the last gear set assuming a module as m=4 mm, and draw the free body diagram of gear 4 showing the forces and torques. 75, 100 2007 In Out 4
