^ agree that public speaking is a very valuable skill. In technical public speaking, a very important aspect is the audience trying to determine if you're worth listening to, and the biggest red flag for me is someone who pretends to understand the question more than they actually do. So...
There are a variety of types of 'corrosion': pitting, surface, and intergranular immediately come to mind. As you might imagine, these each have a very different effect on the propagation of a crack tip. Characterization would be complicated and the crack propagation rate is likely...
I don't know to be honest, but maybe adding an o-ring to one of the surfaces will trap air and further cushion the impact.
I think that if there is any difference, the alignment of the colliding parts and precision of the surfaces will govern the behavior.
When the shaft system critical speeds can be accurately calculated using a static solution it's called a 'rigid' rotor. This doesn't mean there is zero deflection in the system, rather, it means for the purpose of calculating critical speeds the deflections stabilize against centrifugal...
The diagram with the green arrows assume a purely radial load.
I would treat that clamp as a 'bearing' load applied across the opposite sides of the tube. Bearing loads are not radial in direction and will more accurately represent the bending across the section of the tube. Stiffening the...
I haven't seen Gates publish the actual tooth profile before. If you have a link I would also like to have that info.
If was a patented profile, and the patent expired, then I imagine the patent itself should tell us.
I think the detailed tooth profile is an open secret in that there are a...
What are the regulatory implications? If you're moving out of the USA, the first stops should be Canada and the EU. There are differences in what you're allowed to do for personal privacy and data protection. And in the EU your products must comply with CE and possibly other design standards.
This can work if they truly know what they're doing. Unfortunately everyone in the gear industry thinks they know what they're doing. Not all do, or at the very least, not all hold the same standards of quality and design.
The number 1 concern of mine is the mating gears - being of similar...
I create and receive drawings across the globe. My domestic customers (and our production team) need inches. My international customers want mm. Dual dimensions are a very reasonable solution.
Converting from 10.4 to 11 is dropping at least one significant figure and very incorrect. I...
Suppressor and muzzle brake threads are right hand.
But yeah use left hand threads in basically any application where right hand threads would loosen.
One other special case is tie-rod assemblies. You need opposite threads on each end so that turning the tie rod or turnbuckle adjusts the...
I have worked with a helically geared assembly in which the pinion is mounted in an eccentrically-piloted cartridge. This allowed multiple pinion options to mate with a single gear. The original design had pre-machined dowel pin holes for each ratio (each ratio with its own center distance)...
