The issue is I have a fixed pinion center-distance in a low-precision manufacturing process and since I don't have the option to tighten tolerances, I'm trying to make an adjustable center-distance that can manually changed during assembly.
Unless I've misunderstood the benefit of using pin...
I completely agree. But I'm only here trying to reduce assembly time for an existing product, in a manufacturing environment where higher precision is not attainable. If I can't attain that precision, I might as well make it adjustable and get the same end effect with lower cost.
The rollers are made of steel.
I want to be able to set the engagement during assembly, that's why I'm looking for an adjustable design. The current design fixes the center and I have no control over it. The problem is high tolerance stack-up, and the option of specifying lower tolerances is...
If I recall correctly, silencers are fitted on weaponry using a left-handed thread, I believe it's because barrels are most commonly rifled in a right-handed direction, and the blast would undo a right-handed silencer.
This may sound like a comical suggestion but honestly this is what I'd do in your position: take a large random sample of corroded bolts, present them to multiple inspectors and have them judge whether or not each bolt is reusable, and get an average score for each bolt. Then, create your own...
Could you elaborate more on why a go/no-go gauge test isn't valid? If corroded threads are undersized and will pass a go gauge, get your next smaller go gauge of similar pitch and use that as a no-go.
I like your idea, though I am somewhat concerned about relying on bolts in slots to lock the mechanism, especially when they're right next to motor and under intense vibration. I appreciate the input, I'll sleep on it and see if I can solve the issue.
Ideally this would be the definitive solution. However, I live in a country where the manufacturer will laugh if you tell them laser-cutting isn't precise enough. They'll take offense when you specify tolerances, they'll claim they're unnecessary and ask you to remove them, because they can get...
You don't technically need any power once you're at full speed since you've finished the acceleration phase. But aside from the losses mentioned by Dave (which will need constant power), there's whatever loads you have on your cylinder. The rotor can't possibly just be rotating in free air, not...
I have a geared motor bolted onto a moving plate supported by rollers standing on a fixed base. The same fixed base has a rack on the bottom. There are 4 rollers, 2 on each side of the fixed base, and they're on separate shafts (there's material between the two sides, and it cannot have holes)...
The chain gears don't really come into play, if assuming full efficiency here. Gear systems most often operate at constant power.
The power you need in the motor is the total kinetic energy of the rotating system divided by the time required to get to max speed. Depending on where those wood...
Seems to me like the manufacturing process would most likely be on a CNC machine, in which case the result will be far more precise than the tolerance margins specified. I'd go with removing the tolerances, and just specify ISO 2768-MK in your drawing.
I'm looking for a way to document beam diagrams without having to manually place lines and arrows in a word file, which will inevitably look crooked and different each time. I need something standard, preferably with all the symbols available (pin, roller, load, distributed load, etc) that I...
