I was talking to a buddy about blower porting and whatnot and after a little but he came up with this crazy idea. Has anyone ever put a "knife edge" on the rotors? He went on and explained what this would do and it sounded pretty damm cool. Has anyone ever heard or done this?

If you think this is retarded I apologize, It sounded like a pretty cool idea if it would work.

on the rotors in our eaton....duh sorry

 

explain to us what it would do.

 

on the leading edge of the rotor, where it pulls air into the case...could you profile the back edge of the rotor with a "knife edge" to impove efficiency?

I understand you would have to get them machined to maintain rotor balance but if it would improve efficiency.

 

okay well I guess i have my answer....its never been attempted. Glad i have an extra blower setting around for some testing

 

I would be damned surprised if Eaton hadn't tried that. If they could improve the efficiency with that mod, why wouldn't it have been done? It would cost no more.

 

I guess it goes along the same lines as why they just didn't unlock all the power from the factory.......It gives us something to do



I have a buddy who is goin to try it. He is goin to put that edge on it then send it off and have the rotors balanced. Hopefully it will work

 

Far as I can see, all you will do is ruin the blower. It's a compressor, not a crankshaft. The lobes must fit together and have as little space as possible, otherwise you'll lose pressure from the empty space. Besides, there is nothing going on on the backside of the rotor that knifedging would improve on. Just my 2 cents. I'd like to see the results, just be prepared to throw it in the trash when you are done.

 

well it was a free blower so why not try something cool with it. If it doesn't work then it should still work well enough as a cooling fan atop my computer

 

That's right. You'd have to mate the concave portion of the mating rotor to match the knife edge on the lobe. This sharp depression would create a huge stress riser and probably initiate a fatigue fracture.

I doubt Eaton has ever tried anything like that. They're pretty conversative.

 

hey, it could make a nice paper weight, or cut the whole bottom out and make it a flower pot.

 

Why do that........it will just blow hot air on your computer

Porting makes power, why didn't Eaton do that?

Just so you know all off the wall ideas must be painted green.
