Problem 4 The Double Reduction Helical Gear Set Shown In The Following Figure Is Driven Through Shaft A At A Speed Of 1 (152.49 KiB) Viewed 70 times

The double-reduction helical gear-set shown in the following figure is driven through shaft
a at a speed of 700 rev/min. Gears 2 and 3 have a module of 2.5 mm and a normal
pressure angle of 20o. The second pair of gears in the train, gears 4 and 5, have module of
3 mm. The tooth numbers are: Z2 = 12, Z3 = 48, Z4 = 16 and Z5 = 36. Find:
(a) The speed and direction of shaft c.
(b) The center distance between shafts.
