Hello Coupling Group,
Hello Mike,

In my opinion it is very important to know the specification of all parts, because we should create a total part list of all parts we need for the undercarriage. This is a usual procedure which is also standard in industrial production.

Please think about: the "European Airbus Principle" will not work in case you don't define the specification of all parts - and this means also the dimensions of every little screw!

As you may know every school in Europe (also the onces who are not involved in this project) should be able to copy our project and therefor they need the exact specification.

So again, please think about the specification.

Thanks a lot!

Many greetings

Hello,

as Heinz said I thought about the countersink and the screws. In this attached drawing of the anchoring the countersink and the screws are defined.
Sorry for the problems I created!
greetings

Dear Mike,
Thank you for giving us technical details.
Could you also think about giving us a 3D model (.STEP) please ?
Thanks in advance.

Hello,
has anybody tried to draw and produce anchor1 using coordinates from pdf file?
X coordinate of J is obviously with negative sign,
Radius L can't be R4 (on step file is 3.866).
There are some differences in shape (on picture blue are from pdf, black - step)

We produced our parts with the STEP version... I hope it's going to work correctly !!
Thank you for those datas Marek.

Hello Marek,

I remember, that I've heard this from a colleague here in Bad Kreuznach too - and to tell you the truth, it seems that this is not the only mistake in our drawings.

The only thing I can tell you is, that the sharp corner on the left side on top has changed officially to a rounded one - so maybe you don't have the latest pdf version? I think I put the newest version of the coupling as pdf in attachment of this posting.

And I don't know how they have done, but I can tell you furthermore that my students were able to produce this part and nobody has told me something about any problems.

So, maybe you're right, but I think on the other side that time is now too short to change anything - maybe we had have the chance three month ago, but now it seems to be too late ...

In my eyes as a fact we need to arrange ourself with all these mistakes ...

Many greetings

Hello,

I´m sorry for the diffrences between the STEP-file and the PDF. We drawed the anchor in Solid Edge, and we had to translate it to STEP.
In this process the programm makes small mistakes with for example the radius. But these diffrences have no effect on the function of the coupling.

regards,
Mike
