wheel friction

12/15/2009 5:20 AM

Hi,

I'm calculating bearing forces for a turntable with wheels running on circular rails. The wheels are positioned vertically and they are not driven.

Does anyone know how to calculate axial bearing load?

If you're doing what it sounds like you're doing, your loads are indeterminate. Can you provide more details?

I made a simplified sketch of the wheel/rail/turntable arrangement. There are other forces in the wheel/rail interface, but I left them out for simplicity.

In real life the turntable is a circular steel structure with 60 wheels evenly spaced on two concentric rails.

Hope it helps explaining my problem.
