Are there standard shaft and bearing sets for a belt reduction from the stepper/servo to the ballscrew/pinion? I'm use to seeing the end of the shaft attached with three bolts and most of the CNC routers look similar so I'm wondering if these are off-the-shelf items that I can just design around?
Typically there's a shallow "box" with two plates and the router mounts to the outside of one plate and the inside the box are the two gears. Then the ballscrew of the pinion pokes out the other side and the whole box mounts to the gantry carriage.
Am I describing this right so it makes sense? Can you buy "kits" with the shafts, bearings, mounting blocks, etc?
