I've used helicoils for similar applications for years.
Key locking inserts are a step up and work really well.
Both are available as stainless steel if that is an issue.
I think you will find that bends created on press brakes will be much straighter than bends created in a rolling action (like on continuous gutters). If the entire bend can fit within the physical limits of a press brake, it should produce "straighter" results than rolling.
I agree with above comments. I think you have the rotational freedom you're after but... friction from the thrust load created by the weight of the components will be a problem. You need thrust bearings/washers in strategic locations to carry the weight without creating a lot of friction.
As a major user - I agree with all the above!!!
I don't mind a new format, a new look, etc - as long as the same information is displayed. Such as the ability to tell at a glance which threads have new posts since my last visit. Also I really appreciated the list of other forums that used to...
If I understand your image clearly, you've got a couple basic mistakes happening here.
First, what do you mean by "doesn't feel right"? Huh? How much less descriptive could you be? You're an engineer, express yourself in terms engineers will understand.
Second, the obvious intent of the...
How many times have I given this very same advice?!?!
The manufacturer you're interested in has application engineers that are experts in everything about their products. Use their experience and knowledge. They can't put EVERYTHING you would ever want to know on their website.
Pick up the...
Again - how do I say this nicely?
You are over-thinking this WAY TOO MUCH! First - if the actual loads on opposite sides of the wheel are truly unequal, you know that will result in angular displacement. The wheel axis will not remain horizontal. It will rotate about the rail contact point...
How do I say this nicely? I doubt your premise. According to your diagram above, the left side of the top plate is completely unsupported. I doubt it.
I'm guessing you actually have four casters in the system. There are two rails, right? And two casters on each rail, right? And those...
You're getting into an area that will require a good understanding of load and moment calculations.
Something tells me we should also ask this question: The diagrams lead one to believe this mechanism is suspended from some structure above.
1) Is it in fact suspended from an overhead...
You have a classic situation here. Misunderstandings the functions of linear bearings and fluid actuators contribute to poor system design. Two bad assumptions here:
1) The motions of multiple "uncontrolled" pneumatic actuators that appear identical will be synchronized. Wrong.
2) Linear...
Agreed! Just like when Solidworks says it can create animation videos. Yes, it "can". But the voice of experience says you REALLY don't want to try to create a useful video that way!
I have done several SW weldments consisting of sheet metal parts. It can be done. One must be very careful and understand exactly what they are doing. If properly done each sheet metal body will also have its own flattened state. One becomes a master of configurations in the process because...
First off: if the part is only .015" tall, how is anyone going to be able to measure the difference in 43° or 45°?
Second: if you want a metal-to-metal seal you should go for as much contact area as possible, which means absolutely parallel surfaces. (Otherwise you are going to damage one of...
You will undoubtedly have speed variations. This is due to the variation in geometry (swing arm radii) as the linkage components go through their paths. The only way to achieve semi-consistent rotary speed from reciprocating linear motion is with a rack and pinion. Include sprag clutches in...
