Simple gear train Compound gear train Elliptical gear train; Only one gear in each shaft and there is a relative motion between shaft axis. In this gear there is more than one gear on the shaft which is rigidly fix and mashed with the gear on another shaft forming gear train. In discussing the spur gear differential, the use of the term ring gear is a convenient way to distinguish the sun gears of the two epicyclic gear trains. The second sun gear serves the same purpose as the ring gear of a simple planetary gear train, but clearly does not have the internal gear mate that is typical of a ring gear.

Application • Gear trains are used to either speed up or stopped down the speed of the driven shaft . • Gear trains are widely used in modern machines like, in automobile ,ships, clocks, watches, lathes, milling and planning machines etc. 19.

Compound gear train … 01/03/2000 · Even a simple planetary gear train has two inputs; an anchored ring gear represents a constant input of zero angular velocity. Designers can go deeper with this "planetary" theme. Compound (as opposed to simple) planetary trains have at least two planet gears attached in line to the same shaft, rotating and orbiting at the same speed while meshing with different gears.
