Re: CIM Voltage and Motor Suggestions

So what exactly is a flexible coupling and coupling spider? What function does it perform?

Bearing pillow blocks are the blocks of aluminum that have a bearing in the middle right? And then you mount them to your frame and the shaft goes through the bearing, right? This supports the load then, I assume.

You say that "With the flexible coupling, the shaft out of the drill won't support anything at all.", but then why do you still need the bearing blocks?

Re: CIM Voltage and Motor Suggestions

Here's a link to some on McMaster Carr

Drill shaft goes in one side, wheel shaft goes in the other. As you can see, the coupling istelf is only held together if it's pushed from both sides. If you try to bend it or anything it'll just fall apart. So. You mount the drill with that clamp on one side, and then you'll need two bearings supporting the wheel's shaft on the other side.

Re: CIM Voltage and Motor Suggestions

Ahh, so it's sort of a protection mechanism?

Re: CIM Voltage and Motor Suggestions

That and you can use it to more easily couple your direct drive shaft. You can thread one half the coupling and screw it on to the drill, and then use the left hand screw to hold it on. The spider means you can still easily couple it to the other half of the coupling and your wheel shaft.
