Ordinary Gear Trains 1 Ordinary Gear Trains 1. The ordinary gear train considered in Fig. 1 has gears with the same module m = 24 mm. Gear 1 has N 1 = 22 teeth, gear 2 has N 2 = 18 teeth, gear 3 has N 3 = 20 teeth, and gear 4 has N 4 = 54 teeth. Gears 3 and 3 0 are ﬁxed on the same shaft. The gear 1 rotates with an input angular speed n 1 = 290 rpm. The pressure angle of the gears is 20 . Find the angular velocity of the output gear 4, ω 4 .

Ordinary Gear Trains 2 2. An ordinary gear train is shown in Fig. 2. Gear 1 has N 1 = 11 teeth, gear 2 has N 2 = 22 teeth, gear 2 0 has N 2 0 = 17 teeth, gear 3 has N 3 = 51 teeth, gear 3 0 has N 3 0 = 12 teeth, and gear 4 has N 4 = 32 teeth. Gears 2 and 2 0 are ﬁxed on the same shaft and gears 3 and 3 0 are ﬁxed on the same shaft. The centers of the gears 1 and 3 are located on the same horizontal axis. Gear 1 rotates with an input angular speed of n 1 = 550 rpm. The diametral pitch of the gears is 4 and the pressure angle of the gears is 20 . Find the
