We've got the drum design down, been doing them a loooong time. No fear of deforming the drums, the tires are large enough, trust me! These are massive assemblies ;-) Just trying to come to a required torque value on the drive trunnions to correctly size the drive components...

Doh, sorry, I should have been more clear. Yes, we are manufacturing these drums and painting the exterior of them. We would like to be able to rotate them in the paint booth. The surface where the trunnion drives against is a large machined "tire" that will not get painted. Thanks

The surfaces where the trunnions set will not be painted. Thanks

Thanks @Baluncore The mass is evenly distributed throughout the drum and it is empty when being painted. I did not plan to use a clutch. I'm not concerned if there is slip between the trunnion and drum but with the slow speeds it doesn't feel that would be a problem. The trunnion bearings...

Hi, quick intro. I work in a plant setting where we are an OEM for large industrial equipment. We are a small shop. I am a long time machine designer but by no means an expert at anything, especially Engineering calculations. I will contribute to my ability and look forward to...

Hi, I'm new to the forum so thanks in advance for any help. We would like to make a fixture for rotating large drums in a paint booth. I would like to know how to calculate the torque required at the trunnions to rotate the drum using two drive trunnions (with 2 idler trunnions). I've...
