Yeah, I can link the gearbox. The motor shell isn’t ready yet.
I just wanted to hold off a bit on the gearbox because I wanted to write instructions for it and not answer individual questions for each person But it’s the VEX Robotics VersaPlanetary Gearbox. The specific one I have is:
- VersaPlanetary v2 Base Kit, 1:1, CIM Output - this is the 8mm output shaft version w/ 2mm key
- 10:1 gear reduction (select from the dropdown)
That’s all you need to select to get what I have. The 3D printed parts will be compatible with all variants though because of how the gearbox shell is actually designed.
I haven’t tried the integrated encoder option, but if anyone has a bit of extra money and wants to try it, it’s a 1024 PPR quadrature encoder with an additional PWM absolute signal. It would simplify the whole setup (wouldn’t need the rear encoder), which is nice.
Take a look at the Docs & Downloads tab at the bottom of the VersaPlanetary page too - they have a user’s guide, torque ratings, axial force ratings, etc for each output shaft type. Make sure you read the assembly instructions and grease appropriately with White Lithium Grease, which is their recommended grease.
The holes that the 3D printed motor adapter uses are #8-32. But the holes on the front of the gearbox (where the NEMA 23 plate attaches) are #10-32. Caught me off guard, so heads up!
