Dry Rolling Contact Fatigue Design

[BobBartlett]

I am searching for additional information dealing with the allowable design loads for dry rolling contact fatigue. One of my specific applications is like a rotary kiln (i.e. - flat roller on flat tyre).

Are you sure it's dry as it should have A Graphite Block or some other lube bar rubbing on the tire?

You have an almost insurmountable problem to calculate and predicted the failure of the tire as it will definately fatigue rather rapidly.

I've never seen any calculators that were anywhere near the real real world results. What we found was that different suppliers of replacement tires had a different ideas as getting a longer life that the competition.

Some of the things that caused use problems, not necessarily in order, material of construction, how attached, load and speed, and a big on was keeping the tire circular.
Here are two links that maybe of help. I've also seen a paper or two from the cement manufactures. There are papers on the Phillips site and the other link might give you some refernces.

Dear UncleSyd,

The first article deals with:
"The area under discussion is the mating surface between the bore of a migrating kiln tyre and the shell or shell bars that the tyre sits on."

I tried to go to the IEEE site and I registered, but not being a EE, I am not a IEEE member. Does the reference that you cite on the IEEE site discuss my topic? (That is "dry rolling contact fatigue design)

Thanks for your help.

I don't have a specific reference in mind in that paper but was hoping it would give to a lead to other articles by using , say the authors or keywords.

I'm still recalling what the different problems were on our kiln/dryers around the tire.

One thing is we went to a lot of trouble to get the tire rigid due to fatigue of the welds. With the welds we went through all manner of gyrations to get a welded joing that would last. If I've correct the was our biggest fatigue problem, and once said it didn't last long enough to break anything else.

I'll make some calls Monday and see if I call pickup on anything that might put you on the right track.
