I'd like to estimate the torques in a radial bearing at low temps due to the high viscosity of the grease. SKF has a friction model but it is not valid for these high of viscocities, so I am wondering if there is any other way to estimate without actual testing. The oil viscosity at -54C is...
I apologize in advance if this would be better suited for the Configuration Management forum, but I thought it fit well here since it is kind of specific to Workgroup PDM.
I'm working on organizing a revision scheme for my company since it really hasn't been utilized at all. I realize that...
I am trying to find some equations for calculating the diameter change of a compression spring when it is compressed a known distance and one end is free to rotate. Thus, the ends rotate relative to eachother (spring unwinds) and the diameter changes (increases).
In the case of fixed ends, the...
I am trying to find some data on the solar absorption of hardcoat anodized aluminum (MIL-A-8625 Type III Class 1, non-dyed). Since it is mil spec, I thought there would be some info somewhere, but I cannot find anything.
I was able to find some number on emissivity (0.83-0.86), but that was...
I have a question about using the Lewis formula for calculating the maximum torque that can be applied to a gear.
A project uses involves bevel gear sets that are subject to high torques. Our concern was whether or not the bevel gear set could withstand the high torques.
Our independent...
