clutch systems on diesel mills. What RPM's?
« on: April 16, 2016, 05:09:03 AM »
I am going over my next mill build.( I just like to build things). I have an Isuzu 4 cyl diesel that I will turn up to 50 hp. Plan on turning it at 3000 rpm. I have not seen the clutch systems on the newer diesel mills and was wondering what they use. Though about a twin disc setup. I currently have an electric clutch on my mill but don't know if they make one to hold up to 50 hp and what it would cost. I would guess I will need 3 v belts for that much power. I was thinking 1 1/4 blades .054 thick or should I go with 1 1/2  blades? One last thing, what rpm are you diesel engines turning?

I like K I S S. What's wrong with the old tried and true simple loose belt system instead of a clutch. If it ain't there it don't break or cost $$$$

Hi OZG,

there is a similar thread on RPM search a bit here,

Search the clutch WM use on their LT70's  Same power range as your looking at,
or look (Google) to an industrial clutch builder for small equipment, lots of small diameter multi-plate systems out there.

I would go with 1/1/2" bands 0.050-055 range 
Lots of torque pulling the band you need some size there

What diameter band wheels are you considering??

Best

Hello,
 Band blade speed should be at 5300 SFM. WM first attempt at Diesel engines back in 1996 found out that the engine rpm was needed to be lowered to help the band cut quality improve. Higher governed speed may not improve cut quality.
Hope this helps.

I have 26" wheels. But they are made for  1 1/4 bands  I would prefer 1 1/2 bands

You are right 3 belts would be better, i run a few HP myself and use 2 v belts but would like 3 but dont have room, i use the loose belt tensioner, but i dont have a diesel

Hello same band speed.
What are you using to strain the blade? Or blade tension. Different thickness blades have different strain required. .038 thick blade would have a strain different than a .055 blade.

My opinion and wisdom, use 1 1/4' band width. Don't want to start a fight.  ;) Just what I have learned in the past.

Hope this helps.

Haven't decided on strain system yet. My current mill has heavy die springs and they work good. Simple. With a heaver band I may have to go with hydraulic of some kind.
