Kindly guid me about the hub
« on: January 29, 2005, 05:43:31 PM »
Hay All,


Please advice me, I have bought a trailar hub in vuew of constructing Hugh's small wind geny for the start. I had to get down this from England as here in Denmark I could not find. My problem is this hub has two roller racers one on each side. It is loosly inserted. it comes out just by tilting it. the othere one has a rubber jacket on top of the roller racer, and it is also just slipped in to position. I do not know I can use this inserting a piece of iron rod. I am thinking as one racer (bearing)is fitting to the housing (Tight fitting) this will work??

what is needed is a spindel . a special hard steel shaft . exact dimensions for your roller race. threads on the end to retain hub.

I think the hub that Hugh used had ball races, if yours has tapered rollers that will need a lot of extra work.


You can still do it but you will need a precise spacer between the bearings so that when you tighten the allthread you clamp the bearings firmly and the spacer prevents them locking tight.


This would be a lot easier if you can find someone with a lathe to make the spacer so that the ends are parallel.


If you make the spacer so that there is just a little free play in the bearings it will be ok.

Hi -


Sounds like you got a "hub" - what you need is a "hub and spindle".


The spindle goes through the two bearings. The inner (larger) bearing rests on a machined step.


The running clearance is set with a nut that tightens down and removes clearance between the inner and outer bearing sets.


The nut is held in place with a cotter pin.


Or you can try going to your local auto wreckers. Have a look at various cars that have front wheel drive.


Quite often the hub on a front wheel drive car will have ball bearings, an inner flange to attach it to the car, and an outer flange to attach the brake disk to.


This is a somewhat old scan of a GM front wheel drive assembly:





You would be looking for the item labelled "Hub and Bearing Assembly". You can see the attaching holes for the flange, and the 5 bolts to hold the brake disk on.


I think it would give you better results in a shorter time if you get something like this.


Good luck with your search.


Ted.
