Let me get this straight! Oh no, please don’t!

And again a small detail that make a big difference and improve our pikchain®
The first prototype had a straight cut on the guide bar close to the tensioner wheel. See foto nr. 1. But the links of the pikchain® have a certain mass and this mass has a certain behaviour known as inertia.

What happened? The chainlinks, once out of the guidebar and because of their inertia didn’t follow the path of the tensioner wheel and caused too much noise which rose with the speed of the chain.

Solution: We cut the guidebar not straight but curved to follow the wheel radius. We positioned the bar as close to the tensioner wheel as possible. This keeps the links under control.

Result of this little change: The pikchain beomes smoother!


The devil is in the detail

The devil is in the detail: Again! And the devil already knows our pikchain.
There are quite a lot places in our pikchain where he can hide and wait until you discover him too late. One of theses places has been found recently and the devil was amused!! When you build the frame of your pikchain without any possibility of finely adjusting the guide rails (horizontal and vertical), then it may happen that different tolerances add in such a bad way that the pikchain sticks between the rails and can’t move anymore. In this case you have to modify your frame, which can be very cost ineffective and time consuming.
The easiest solution consists of having a design with oblong holes. Don’t give the devil a chance.



Interface: c-chain/pikchain®

There is a section of the pikchain®, where cables and hoses coming from the energy chain must be diverted to the inner of the conveyor chain. As long as the cables and hoses have no big outer diameters everything is ok, and to prevent additional wear between the cables and hoses you can add protection hoses. See picture.

But in the case that you have really thick pneumatic hoses you will have a problem diverting the hoses from the energy chain to the conveyor chain because of the acceptable bending radius. It will be too big for the chain.
Specifically for this problem igus® have created a special link. This link consists of a channel, through which the air finds its way from one hose to the other (marked red). Result: No bending radius, no wear, no additional and the lifetime goes up.
