Amazing! Functioning mechanical gears in an insect

You will find a lot of useless stuff in the wide seas of the Interent. But every once in a while you come upon something that makes your jaw drop. Here is a great example.

Functionig mechanical gears in an insect
In 2013 a team of scientist from the University of Cambridge in England found out that a common plant-hopping insect, that you will find in your garden as well as in mine, is using interlocking cogs on its hind-leg joints to jump. Professor Malcom Burrows and his team detected that the gears in the Issus (that’s the correct name of the insect) “bear remarkable engineering resemblance to those found on every bicycle and inside every car gear-box.” Each gear strip in the juvenile insect is about 400 micrometers long and has between 10 to 12 teeth. Both sides of the gear in each leg show the same number, which makes a gearing ratio of 1:1. Fascinating isn’t it?

Could we produce a gear-implant for this wonderful insect using our high-precision Multigrind® CNC grinding machines? No, I don’t think so. However, you can produce all kinds of gears, gear parts and gear cuttings tools on our machines. Precision in the micrometer range guaranteed! If you want to talk with me about grinding gear parts, please send me an e-mail.

So much for today. Schleifen Sie gut!
