Just to share one cool pillow block / stepper housing design. This was designed to take a pair of 6801 bearings and a NEMA 17 stepper, hence the parameters in the script. In my application it will receive a shaft loaded in cantilever.
The assembly for my application (without bearings), to hold the bearings in place, we have in one side a flange (purple), on the other a flanged nut (not shown) screwed to the shaft. In red is the shaft designed for my application, with a groove to receive a belt. In black is a representation of a stepper motor.
Here is the pillow block / stepper housing alone. The feature on the top is an access slot for easy access to the curved jaw coupling. Inside the cylinder theres a ring, meant to be an spacer for the bearing pair.
The cadquery code for this part:
All the parts ready for the assembly
The shaft with the groove for the belt
A custom hand ground HSS tool bit made to cut the groove in the shaft. Worked like a charm.
Once again,
Cheers,
Edi
