In my haste to get something going (as we’re now in summer here in Australia) I ordered a 2nd hand Neugart PLE40 5:1 on ebay, not noticing it had a larger square section over the coupler.
This meant the @pacificmeister Motor gear box mount doesn’t fit, as there’s too much distance between the SSS motor shaft and the coupler. So I’ve rejigged the Fusion 360 files to make it fit with the larger section. This gives the shaft about 10mm of length to attach onto the coupler which I’m hoping is enough.
The Fusion file is available here for those that need it: Motor/Gearbox mount for larger PLE40 Gearbox. Let me know if you need the STL version.
I think I’m going to have to drill the 4 holes in the square gearbox mount to allow the M4 screws to go through the entire length… Otherwise, I can’t see there’s anyway to secure the gearbox AND the motor at the same time, unless it goes through to the seal mount cover to secure it.
I’ve got a bit of a question about the coupler
-from looking at the CAD, the only coupling between the notched drive shaft and the gear box coupler is through the use of the grub screw on the coupler? Is this is enough to hold even with the torque?
