Planetary gears 03/11/16
One of the most interesting inventions ever created by the human species is are planetary gears. A problem come across by many Engineers is as follows: How can we make a smaller gear turn a larger gear while being encapsulated in it? The solution is to use a planetary gear mechanism. The trick is to use a central (smaller) gear called the sun gear to turn a multitude of other gears called “Planet gears” in the opposite direction which in turn which turn the circumferenced gear (called the “Planet gear” ) which in turn will turn. This is used frequenly in autombiles.
