Since childhood I have always wanted to know how he watches ingeniaban to make the seconds hand jumps off, instead of maintaining a continuous and uniform motion.
I could understand that circular motion, a gear wheel, could be transmitted to the other wheels of different sizes achieving varying speed, but:
?How is getting out to the second hand jumps?
As a picture is worth a thousand words, I leave an animated gif that sent me a love coworker mechanical animations, in which it becomes clear what the mechanism of this “complex” system. At the end leave a link which is due for this information.
I must admit the ingenuity of some inventors.
Imagine that sprocket (green) makes one revolution per second. In animation has slowed to appreciate in detail the operation.
Imagine that slotted wheel (Red) you have 60 instead of six slots, and carrying rod mounted seconds. Another alternative is that, keeping design, the sheave transmits the motion to a new wheel having attached to the second hand.
And now enjoy the animation.
