ok tittle says it all I have a new project , I want to build a waste oil centrifuge but I can't get it in my head how to make the inner rotor connection to the shaft (direct drive or pulley) that goes through the outer house/pan to the motor. I can't go bigger then 10" diameter for my inner rotor pan either cause that is as big as my old atlas lathe will turn.
Here is a very poor and basic drawing ( I ain't no artist!) I have the basic idea of how to build this unit but there has to be some way that I am missing to get a bearing/race and some type of support other then just the motors drive shaft. This unit will spin between 3400 and 7000 rpm so you can understand why I want more support but it is just eluding me at the moment , which normally means its simple and I am just overlooking it.....lol
I can comprehend something like say cutting a old crank shaft and mounting to the bottom pan and use a bearing and race for support but then I can't drive the enter pan or I can see a elec motor shaft with a key coming right though and supporting the enter pan but when it spins up to all those G's with oil in it I am afraid the elec motor shaft alone will not be strong enough to support it ....... hoping someone can kick start my brain with some suggestions
