Unfortunately I can't without doing a ton of work to blot out proprietary notes, which wouldn't leave much left to look at in this case...
The weld I had pointed out happened to be on a main plate loaded primarily in shear.
In any case, I feel like I have gotten the info I was looking for...
I think I see it. If I consider the throat to be from the root of the original groove weld to the face of the reinforcing fillet weld, that would certainly be larger than just the groove depth. Is that what you are saying?
Dhengr,
Can you elaborate on this? I had originally thought that the smallest throat dimension of the combined welds would be equal to the groove weld depth, and that the fillet weld wouldn't really increase this.
Regards.
Hello, Just a general question here:
On many occasions now I have worked with 1970's vintage prints for large industrial machines (mostly presses). These presses are often heavy plate weldments in the 2-6" thickness range. I have noticed on a lot of these prints that it is common for a large...
Thanks for the information and material ideas. I did end up contacting a band brake manufacturer just to get additional info, and of course they agreed it is a difficult application. They indicated that stopping the friction material from shearing off would be a challenge given the relatively...
Tbuelna,
The conceptual device is going to be an external style brake unscrewing two components, the bottom component has a keyway to prevent rotation, while the top component is machined smooth and the customer is unwilling to machine any mechanical interlock features into it. The smooth...
General question- what classes / alloys would be good candidates for a band brake application-(the band itself)? This is a very preliminary concept for a design at this point, application would be static and room temperature. Anectdotal applications or experience are welcomed, also feel free...
Brimstoner - this is the parallel conclusion I arrived at today. I'm likely going to use drill bushings.
EdStainless - Great idea. I think I can achieve this partly with the drill bushing idea, and I may be able to upsize the base of the pins.
Thanks to all.
I took the tolerance issue into account by factor of safety.
I should clarify: I don't necessarily need a definitive answer, I would just like to hear people's opinions/experiences- like you shared.
I like the idea of localized hardening, thank you for the information.
Regards.
Hello,
I am designing a rotary yoke device that is used as a spanner wrench to unthread 2 components. Actuation will be steady hydraulic, impact will not be used. I would like to make the yoke out of 3" plate. I am considering using 4140 moderately hardened, or possibly A514 as-is. It...
Hello,
I was wondering if it is generally bad practice to intentionally put HSS (square) into transverse compression, and by this I mean laying the tube on its side and putting a "crush" load on it. Just for a little background, I need to create a base for a large metal tub to sit on that has a...
Hello all, I am sizing a small natural gas line with a starting pressure of 40psi for an industrial application. It will need to flow 8300cfh, the pipe run is 3500'. I was going to use the Renouard equation, then I read in a piping design handbook that the compressibility factor "Z" doesn't...
