Love Joy Coupler: DVR Torque
Posted: Fri Aug 17, 2012 6:24 pm
I was going through some old forum posts and came across on a new coupler called the Love Joy. I don't need any couplers as I have good supply of them.
In any even I emailed Love Joy and they requested the following:
Bore sizes of both shafts (and keyway sizes if they are keyed)
Max RPM
Max Torque or HP
Well, thanks to a different thread, I know the shaft size is 5/8". However, I do not know if a 5/32 set screw needs to be drilled & tapped like the new ISNS insert adapter for the G3 Chuck. That thread is still on going.
I know the DVR motor puts out 2 HP at 240 VAC with a max 10,000 RPM. Imagine if it went as fast as a router- holy cow. But the question I can't answer is what is the max torque other than it is double at all speeds. Is there a conversion chart? i found a conversion formula and my numbers don't appear to be correct= 3.8 ft-lbs at 10,000 RPM. If I use the same formula at 5,000 RPM, I get 1.9 ft-lbs of torque. What confuses me is it is my understanding the DVR motor's torque pretty much constant.
Anyone know?
