Universal joints

[anto44]

Car steering joints won't be rated for very high rpm. The max rated torque of a UJ will be with the joint straight, the max torque will reduce as the angle increases.

That’s a valid point. The winch owes me the sum total of about 30 quid so I’m trying not to spend too much on it!

If you can keep the angle of the shafts as low as possible that will help your cause.
Might be worth taking a look at 4wd farm quad driveshafts and joints. They would be around the 20mm mark and should take a fair bit of stick.

Hadn’t thought about those

Hadn’t thought about those

25-30mm on most quads.

 

[sako243]

to allow some angular misalignment

So don't misalign it

Any good ?

20mm shafts are common enough.

I have purchased and installed reasonably priced UJs for 20mm shafts from WDS

Agricultural engineers uses all types, sizes and ratings.

I would have suggested your local agricultural shop too. They will have all sorts of stocks of uj's used for PTO's etc.

Pto's tend to run on 2 or 3 lobed tubes that slide into one another, with 6 or 21? Splined shafts on the tractor and machine end.

Sorry, perhaps I am a little confused to which part the OP is after, when they said uj I had assumed it was the component (cups roller bearings and spider). I take it they need yokes etc. aswell.

 

[Rkweld]

A quick picture of the setup would maybe spark some ideas.

Power rating?

 

[8ob]

Power rating?

Less than 200nm Mike and that would be if the pump was in good health, if its what I think it is it will have a stator motor on it.

Pretty much anything that will fit the shafts then I would think ...

 

[dan.taylor.1]

I mean a 1/2" uj from a socket set will take 300nm through a torque wrench!

 

[Tinbasherdan]

This is the original setup, the motor bolts to the front cross member and the shaft mates with the input on the winch

I have made a spacer as below to close couple the motor to the winch itself, another variant of the superwinch setup. This clashes with the xmember

 

[Tinbasherdan]

I do wonder if I could find a motor with a shorter body though....

 

[Rkweld]

So is the shaft to fit in the new coupler or is it to drive the pump for the motor you already have mounted?
