If it were retrofitted with a thrust bearing it would be easy to change out years down the line if needed.
If you were to substitute only a thrust bearing, what would keep the axis of rotation centered?
Will you mill the grooves say 4mm deep to leave a 4mm gap for a 3mm drilled ring to keep the balls separate?@Ischgl99 to answer your questions,the material is cast iron and no I can not grind it after milling,BUT like I said before this is a windmill and not a high presicion tool and the cast iron is not hardened in the first place. That being said,the client are happy with it just being milled with the ballnose cutter and do not want to go with the thrust bearing option because of the expense. The bearing is a bit pricey. But I gave the options and he is happy. I gave the pros and cons and he still said I must just mill it and I did not want to **** him off so I will do what he wants.
Thank you for your input, I do see your point of view.
Yes I will get a piece of delrin for the ring.Will you mill the grooves say 4mm deep to leave a 4mm gap for a 3mm drilled ring to keep the balls separate?
For what? The ball cage? Polyamide would be better since there are commercial bearings with polyamide cages, but if all you have is HDPE, it should work provided the bearings are not highly loaded.Quick question. Would HDPE do,because I have some on hand?
I understand completely, customers always want the cheapest repair, and rarely understand the ramifications of their decisions. I thought it might be cast iron from the pictures, in that case, it should machine well, but you might want to touch it up with a fine sandpaper a bit by hand to take any high spots off. Bearings are under a lot higher stress than most people realize and the smoother the surface, the better the life will be.@Ischgl99 to answer your questions,the material is cast iron and no I can not grind it after milling,BUT like I said before this is a windmill and not a high presicion tool and the cast iron is not hardened in the first place.
