Right angle diff - small project

Well Gene from Agrisupply responded to my question about load and rpms for that gear box:

"This gear box is made for a fertilizer spreader and will not handle this kind of r p m., it is a 540 max. r p m."

Bummer.
Hmmm. I wonder though, If you used a 3600 Governed engine and geared 6:1... Then you are turning that gear box only 600 Rpm.
I dunno those Guys on "Cars and Cameras" used it.

yah good info. i was planning on gearing down before the diff. So maybe i need to get down to 7:1 maybe? i don't think i want to go 27 mph in this thing. more like 20 mph? maybe even 15 mph? will need to calculate that out.

anyways here is an updated CAD drawing. Guesstimated my best on engine size so i can get an idea. Will need to go back and measure mounting holes etc.... but that can be done on the fly. This cad is more to see if it makes sense and if i'm missing something.

This is done in pro/e with mechanism so i can animate it if needed. Takes some extra effort putting together that way. but it looks cool.

What do you guys think about vertical shaft engine with Chain Or Pulley? My first concern with pulley is i need to design this so i can change it, which is currently a design pain. i think i can design around it. but maybe chain is better and i wont have to worry about how to replace if it breaks later.

What is everyone's experience with a chain drive system on its side like this. See above post for engine to pulley orientation.

Better to do pulley or chain?

look for a PEERLESS 1050 right angle drive gearbox
1050 specs

it might work.

Watching a youtube video and someone used this for a diff on a lawnmower go kart.

looks a little beefier and only 100...hmm not sure if i can get that. doesn't have a drop down for usa Maybe i can talk sid into receiving it and then shipping to me since he is in germany and they ship there.

Here is this guys video

Sent rons bits and email to see if they can ship to usa?

Ron got back to me. He is going to see if he can get his website to show shipping to USA. But i have spent too much money on my stupid hvac this week. Need to save up some money before i buy anything else.

I think there has got to be some local to the States.
I thought most of those racing Lawn mower guys use a RAG ( Right Angle Gear) Box. *shrugs*

Yah im still searching. I may go with the one cars and cameras use on there kart. If i go 6:1 ratio first then through gear should be okay. Maybe even 7:1 , 8:1

I liked Theirs but Some one just posted it is 540 RPMmax

I liked Theirs but Some one just posted it is 540 RPMmax

So engine at 3600 ratio 6.6666 gives me output of 540 perfect. Ill go 7:1 should be good can always gear back up right?

Here is an ebay one for 90 might be good?
