Minibot Motor Press Fit

[Trent B]

Red loctite can also be used to secure press fits. We have it in a custom gearbox securing a RS775 to a tough box shaft and it has worked great.

If you have Loctite 638, then I would recommend that over Red (271) for press fitting something onto a motor.

I was going to mention that, it is actually made for press fitting two smooth objects together, oddly the local autoparts stores here didn't sell it even though it is often used for bearings in cars. So we settled for red loctite which works in low torque situations (like our lifter)

But similarly, I am not sure 638 is technically allowed on the minibot where-as Loctite designed for thread-locking is.

I would like to introduce you to a wonderful site of utilities for the shop:

Many, many programs that calculate whatever you need to do in the shop. Your answer should be found with the FITS program.

Go up one level and you will find a bunch of math programs as well.

I have also noticed that the KOP CAD models from PTC have incorrect diameters on the motor shafts.
