Planetary gearbox on mini CIM without cutting shaft


#1

How do I put versa planetary gearbox on a mini CIM motor without cutting the motor shaft?


#2

You’ll have to make your own adapter. The current CIM motor mount for the VersaPlanetary requires you to cut the shaft. If you have access to 3D printing, this should be a pretty easy part to make.

Sniped!
+1 to 3d-printing a spacer to go between the CIM-motor adapter for the versaplantary gearbox and the CIM motor itself.


#4

We have done it for off-season projects using regular CIM adapter plus the regular input VP slice (roughly .5 inches) plus a VP motor mount for a 9015 (or other, about 1/8 inch) as a shim and then gets the right stack distance.

I made one for a v1 versaplanetary a few years ago and posted pictures of it. I had to pass the shaft through the sun gear to get the key and keyway work out.

In addition to Vex’s CIM adapter:


I found three different parts on AM a few months ago which can be used for CIM shims; two are specifically designed for this, the other I just happened to notice had a 2" bolt circle.

Hi, Even with a 3D printed part, don’t I have to cut the shaft up to the keyway to install the input coupler with the key onto the shaft? Or, am I missing something?

You aren’t missing a thing!
At the end of the day the shaft adapter and motor shaft keyways require the shaft to be cut down.
