90 degree gear box build questions?

[ajc894]

I am thinking about building a 90 degree gear box. It would be to put all the vertical shaft engines to use. question, could I use a set of old differential gears to build it? And would they be strong enough? or should I just buy one?

You COULD build one using the gears from a car diff. But, it would be better, easier to just buy one, from www.surpluscenter.com as an example.

I'm curious about those too. Do you have an example of which one would be good? And do you just stick your clutch/converter directly on the other side of the gear box?

Any of these would work, just depends how much bread you want to part with.... http://www.surpluscenter.com/Power-Transmission/Gear-Reducers-Gearboxes/Gearboxes/

Yes, your clutch or sprocket, whatever..... Would attached to one shaft, the other would drive the axle.....

This is an interesting idea; I have a riding mower diff axle laying around somewhere; the housing is flogged out but the gears are fine; the gears are all cut at 45° & the two side gears are notched to hold a 3/4" axle so, I can't see why it couldn't be done...

PS, LOVE your sig

I think I'm going to try it, as I have more time then money, plus access to a machine shop.
It is going to be similar to the peerless ones. (http://www.peerlessgear.com/node5379.aspx?nid=300861) as the gears I have are from a peerless trans and look similar.

PS, Thanks it's one of my favorite quotes

Oh you lucky ***** I WISH!

You do realise, now that you've said you're doing it, we want to see a detailed build log :toetap05:

So what car diff are you planning to use?
I'm just thinking you are going to need plenty of space, as the ring gear already takes up alot space. Might have to mount the engine higher to accommodate some kind of ground clearance.
An interesting build for sure.

The diff is from a peerless transaxl. So its relatively small. Still figuring out the bearings as there a bit of side load. cause the first set to lock up. So I am back to the drawing board.

If you aren't, try tapered roller bearings.... They will most likely get rid of the problem.... Try looking here......

That's what I was was leaning towards. Not sure how to keep them together, c clips maybe. Should the cone of the bearing face in or out?

 

[DeathMachine]

Should have 2 taper bearings on each side, with tapers facing each other.

 

[firemanjim]

In, iirc..... Post some pics of what you put together. I might have an idea or 2 to keep it all in place......

Should have 2 taper bearings on each side, with tapers facing each other.

Why would you need 2 on each end?

 

[DeathMachine]

to keep from squeezing the mounting points together. Think of how car wheel bearings are installed.
