Thank you! That was what I needed to learn more. 

 

Any recommendation for a reference work that can fill these occasional gaps in my understanding of mechanical connections?

Its a spline.   Very common on transmission shafts.   Allows for a slip fit and very high torque capacity.

Hello,

I am evaluating an EV kit and I see this shaft on a drive motor... notice the female toothed grooves in the shaft... and I've not seen this before nor can I figure out what it is called.

Does anyone know the right way to describe this kind of fitting and what the corresponding male part looks like (say, for mounting a pulley)?

Thanks,
