Housing covers for 3:1 steel gears

Hi all,

Ralf has m as I recently brought up with an idea to provide the 3:1 steel gears with a cover.
So I sat down in the evening when I was in the business time and a little drawn.



And so the prototypes are already in print.



Tomorrow I can see ma exactly how they fit and if necessary adjust anything else.

I'm still not happy with it.

This is the second option and I have to adjust the cap in a few places and around the drive wheel a little better.









In the third variant, I just draw and this fits most then.

Today coming from the printer early covers are now almost usable.









I've made ​​a few small changes to cover also the last gap and better gestallten especially the enclosure of the drive shaft, but that should be it now.

So the first four pairs are now in print.



However, there will be such that one on the drive axle to the tub for installation and something has to adapt depending on space and reinforced the covers. Depending on how much space is available in each tank.

And today I have taken the time Asiatam flat gear into the business.
Time seeing how I as a full coverage approaches, and bring a few Tamiya gear I have are still here.

Now the covers are done constructively .

Just as she now has to come out of the printer you but first remove the support Struck doors, which is not so difficult but .
To do this simply pushes a knife or a thin screwdriver under it and levering it on the sides , piece by piece from . The PLA used then breaks off brittle.





And so do the insides without these supporting structures.



If you then have the space in the tank , you can simply back the covers , like start in this picture and simply clip it with a little caution to the front.



Unfortunately, it will not be when the transmission queue directly on the front possible in all Hull. Since one must then match the best cut off the front, with a small blade.

And this is what the covers then the transmissions from now .





And here I have put them in a KV- bath times.

Yesterday I casually sometimes drawn a first prototype for a cover of the Asiatam flat gear.



Since both of these pair of gears are the same, but mirrored and I just have to adjust a print first. If this fits then simply reflect the drawing and I have two matching covers.

Let's see if I can still print the prototypes evening today?

Very nice job Edwin!

  tecnicamente interessante il nw progetto dim cover per riduttori asiatam , gia' il disegno in 3d lo esplica moltobene , saluti robby62 ....   

Today, the first prototype was ready now.





When I tried but I had to then determine the fit, it was probably been but a bit late and a long day as I drew the .....





But never mind, because the first component anyway never true. So improved and currently has been running the printing of the second prototype.

Today I was able to try out the new cover on the flat gear.

That now looks much better.





Some small changes and even then it might fit.

The final pressure was now almost usable.





What I had to adjust I made and now run 6 covers on the printer overnight.
