Best type of spline for misalignment and easy engagment

Aconcagua · Jun 28, 2019

I have a tool that will be engaging with a motor. The spline to transfer torque between the two is 1/2" diameter, and only needs to carry 18 Nm, so I'm not overly stressing it. It might not engage perfectly straight and it might not align perfectly well.

My plan is to use a hex spline with some slop and a healthy chamfer on both the male and female side. Any other ideas?

Thanks

Lots of tools use a square socket, these tend to wear to the point of unusability far less quickly than a hex.

Would a ball end hex driver work:

Thanks! That's a good idea.

A little more specs on this spline. It will have a very low duty cycle, and when it's loaded it will generally be stalled. It's also subsea, so my plan is to Xylan the female part.
