Here is the link to the video on Youtube

FreeCad allows all parameters to be fully customizable and the animation helps in seeing the meshing

I am not an engineer, but 40 years of experience as an AG technician help in having a feel for what should work

And indeed my latest clock with a Grasshopper escapement works nicely

I will be happy to share how to get the geometry, CAD program do make it easy

Also links of interest about cycloid gears:

Owner allowed me to share the links, so here they are

Meshing of cycloidal gears

Geometry of cycloidal gears:

https://www.tec-science.com/mechanica…

x(t) = (R+r)*cos(t)-r*cos((R+r)/r)t)

y(t) = (R+r)*sin(t)-r*sin((R+r)/r)t)

Where R is the radius of the big circle which a smaller circle with radius r rolls around.

I calculated my pitch diameter from PD=P/sin(180/z)

Where P is pitch and z is number of teeth.

I cannot replicate the results and the information online is scarce. Could you please give me some insight into what equations are used in this calculator?

I can’t understand how I can do my wheel chair right,left,stop and reverse It is going forward only.

Thanks ]]>

code for motor Left , Right , reverse and stop using push botton for IBT2 driver

I can’t understand how I can do my wheel chair right,left,stop and reverse It is going forward only.

Thanks

Thank you so much Rainer, it looks perfect as far as I can tell! 🙂

Best wishes

]]>Hi

Did you manage to get the controls on the IBT-2?

Hi Jens,

The inner gear should work now. I needed to roll out the inner gear a bit more to create a correct ‘cutter’ without the hump that you noticed.

]]>and if you have Content and articles about designing this type of gear would you please share with me? ]]>
