If you are dissatisfied by rack and pinion problems that may possibly occur during any operation, reconsider. Did you know that it was from the simplest of inventions that the more complex inventions were inspired, complex inventions like a magnetic train and the like? You would obviously not believe that it was from the simple rack and pinion mechanism that the MAGLEV technology was initially inspired.
Of course no technology is perfect and that holds exceptionally true for the most ancient of technologies, of course we are talking rack and pinion here. The technology was invented just as soon as the first wheel was put to use, the first time a circular objects movement was manipulated to carry heavy loads across distances, and the rack and pinion was invented.
The concept is simple, one wheel or a cog or any round object moves along its circular axis. Now if you place a straight rod adjoining it, the rod will start to move as the round object does, of course if there is enough friction. And thus you get the basic rack and pinion equipment, the most elementary mechanism in use all around us, in cars, in trains and even in factories as conveyer belts.
However you may think the mechanism unworthy due to the apparent friction. Continual friction on any object not only diminishes any mechanical advantage, but also wears off the object subject to friction. But the latest technology has diminished most chances of friction. Did you understand what the jays in both the cogs and the conveyer belts are for, or did you fail to notice the ball bearings most cogs have these days, these are attempts to reduce friction, and while there is still some amount of wear in even these wheels, you can be sure that it will take very long to get known.
