Threaded Connections
Threaded Connections
(OP)
Greetings! I have a question that maybe you can answer. I will try the best to explain below.
I have a hub with through holes in a circular pattern located on flat surfaces that are milled. There is a connector bar that has tapped holes that are placed at a 4 degree pitch to the top face.
Can someone tell me the benefits of a threaded hole that is at a 4 degree pitch with a thru hole that is straight through? I feel this is causing major issues in assembly and other engineers feel the same but one engineer will not say why this is supposed to be this way. I may need to upload a "SAMPLE" print for you to see what Im talking about.
Thanks!
Justin

got a 404 error on the pdf.
Is the "connector bar" circular too?
Kind of like a belleville washer perhaps?

I pictured a "nut plate" square/rectangular in cross section, but curving around to include several of the threaded holes, like a big washer, possibly cut into a few "C" sections.
Upon tightening such a thing with skewed holes the action >>might<< be similar to a belleville washer but at the poor bolts' expense and health.
