In this case, each intermediate shaft has two gears rigidly fixed to it so that they may have the same speed. t F = number of teeth in wheel sprocket. 1 and 4 rotates in same direction and also they are co-axial gears. They are both used when there is only a small space between the input and output shafts and l. The speed ratio of compound gear train is obtained by multiplying the equations Found inside – Page 258Unlike simple gear trains, compound gear trains contain at least one shaft carrying more than one gear. Compound gear trains allow for a more compact design and are commonly used for speed reducers such as that shown in Figure 8.3. Similarly gears 3 and 4, and gears 5 and 6 must have the same module. A simple planetary gear consists of a ring gear, a sun gear, and multiple planet gears, where typically the sun is the input and the planet carrier is the output. Ordinary gear trains have axes, relative to the frame, for all gears comprising the train. gear 6 is the driven gear mounted on shaft D. Let N1 = Speed of driving gear 1, In this type, the perpendicular axis of the gears tends to intersect at a certain point.
