So, with one day before ship, we’re getting started on our end effector. (C’mon, we’re only a little bit behind…)
We’ve identified the Denso motor as a good match with what we want it to do, but we’ve hit a snag: we’re not quite sure what’s the best way to attach the adapter that came in the KOP to the motor’s shaft. What would seem to work is to poke a hole concentric with the output shaft, then put a screw in that’s large enough to keep the adapter engaged, but IANAME.
Is there some practice I’m just missing out on by searching “denso motor adapter”?
I haven’t tried it, but my guess it that poking that screw hole in the shaft would be challenging.
How about supporting the adapter by the other end, perhaps a shaft and pillow blocks or something could hold it in line. I think the adapter is meant to only transmit torque, not to hold something onto the motor output shaft.
One thing to keep in mind here is that the metal shaft sticking out the center of the plastic splined piece of the denso motor does not rotate, it is fixed. The plastic gear and splined bit rotate around the metal shaft like a dead axle. If you put a screw in the end like you are proposing, it may be subject to unscrewing itself with normal operation of the motor.
I am not sure of your setup, but in many cases I have seen the Denso motor used with the long keyed portion of the plastic KOP adapter removed. If you are doing this then you could probably groove the end of the fixed metal shaft and put a snap ring on it. If you have little pride (like us) you can make this groove with a little care using a bandsaw or a hacksaw.
