Betreff: Finding the curve of a gear profile

Hi @JordanMcB

 

 

So this brings me to the next question, and again sorry that I am not able to open the part at the moment, but I must suppose that there should be the first tooth in Your model and that this one will be patterned afterwards.

So it should be possible to change that single tooth, isn't it?

 

 

Can You make a picture showing the pathfinder of Your part?

 

 

 

 

regards
Wolfgang

Hi Wolfgang,

Thanks for all of your help with this. I did not use the pattern tool to reproduce one gear tooth N times. I used the engineering reference tool; strange constraints seem to happen with parts generated this way.

I think my solution will be to export to STL and then import the part file. Hopefully that will make the difference

Hi @JordanMcB

 

 

I can not imagine, that they have not used a pattern too.

 

But if this strange situation should be true, then to not use STL for export / import.

Just save it as parasolid.

But  as far as I can remember the Engineering Reference creates well modelled traditional parts where one tooth will be patterned n times.

Wolfgang

Hi @JordanMcB

 

 

 

And as already asked, please show us an image from the pathfinder.

This would help me a lot (out of SE)

Wolfgang

Hi there @JordanMcB,

 

Could you not simply make an offset sketch, using the "Project to Sketch" [check the Project with offset setting] command, set with the "Loop" selection filter.....then make your appropriate extrude or cut.

Hello,

 

I need to generate an involute metric spline for the model of a splined end on a drive  shaft. It would be a external spline to DIN 5480 or the ISO equivalent. Could you tell me the best way to do this. I tried skretching the spline profile and performing a " cut out " feature and pattern but the profile tolerances did not come out right. Could we use the gear program to generate a shaft profile?

 

Would appreciate if youi could help.
