That looks like a whole lot of set screws…:eek:
I hope you plan on putting some Loctite on those screws.
I also notice a slight misalignment of those two sprockets. #25 chain isn’t very tolerant of this, You probably should fix that before it gets worse.

Not positive, but is this a CVT?
Just a 2 stage sprocket reduction off a window motor, not a CVT, those usually look alot fancier.
it would appear that the cone is just a modified window motor adapter.
