N is the gears teeth number, the sign depends on the type of gear and, geae sequence is for external gears. Unit 3 power transmission devices devices structure 3.

Automatic transmission has not better fuel economy. Will be grateful for any help! In a compound epicyclic gear train as shown pdfinancialcorp com in the figure, has gears. The motion of helical gears is smoother and quieter than the motion of spur gears.

But in case of epicyclic gear trains, the axes of the shafts on which the gears are mounted may move relative to a fixed axis. Hence the gear ratio has the same meaning as in the simple gear trains. Spur gear design and selection objectives apply principles learned in chapter 11 to actual design and selection of spur gear systems.
