    The point of bearings is to test them under load just to spin them without load is no point, that's why bearings usually don't have oil but grease, but otherwise great videos keep up the good work. Ära südamesse võta väikest kriitikat.

      @Dennio83 3 года назад +4

      well there are some things you can bagage along from early tests without any load because the bearing will always be under its own load. Noise, temperature and the delta of time at free spinning do contain telling characteristics 99% of the cases. And with known materials like 3d printed objects this can be extrapolated to 99.9% of the cases. With the right math that is, just like something as Ultrasonic testing. Oh and when you see white ball bearing material come out of the crevices when spinning freely with a simple motor, setting up a test with load would just take up more time to get the same result.

    Very interesting and thank you.
    The second bearing style you tested, is a conical bearing, and Christoph Laimer has another version that he calls "slew bearings". If you print the bearings first, you can print the inner and outer races together up to a little more than 50% and carefully drop in the bearing and continue the print. This way you don't need screws. There is the idea of an "airbrush nozzle" that could make that even easier which I am about to try. Also, I found that AirSoft projectiles are either
    Non-biodegradable airsoft BBs are usually made from a plastic acrylonitrile butadiene styrene (ABS) OR Biodegradable Airsoft BBs are usually made from a plastic polylactic acid or polylactide (PLA).

    If you lower the tolerances between gears and add a temporary grease in the gears you can make the gears "wear mesh" without creating massive play. Any inperfection will powder grind and create abrasive that grinds the gears, grease will capture and protect the gears while they are ground down and hardened.

    -You should put some some grease in between the gears on the geared one obviously. And see if it still wears out.
    -Use grease (or Talcum powder) in the ball bearing, instead of WD40.
    -Also try printing the balls for the ball bearing in ABS instead of using the bullets.

    Hi! Any gears (metal too!) goes through "team play" process. After working together for some amount of hours they're has to being checked and re-assembled if everything is fine. So you've just got rid of excess material. If you want really test this bearing you should make some moving system that will be giving adequate loads. This will show if it will be working fine or will fail.

    • @SianaGearz
      @SianaGearz 4 года назад +1

      I wonder what ABS he prints with, but ABS is very different from each other. It can be pre-degraded from regrind, reusing the moulding leftovers in a new batch of product, and especially if you look at small pellets, you have to suspect that a lot of flashing and injection spouts were removed from them and reused in the next batch of pellets, and every cycle of heating degrades the polymer quite a bit, so you expect some polymer in there that is maybe 10 generations of regrind. It tends to contain free styrene, thus the printing smell - and you know that not all ABS filament has the nauseating smell at least not to the same amount - and it tends to also contain free styrene flake that separates out and makes for low abrasion resistance. It has also been suspected that some 3d printing filament manufacturers, what they sell as ABS really isn't, but is a different styrene copolymer, like SAN or ASA, because printing actual ABS is more troublesome. Even just a reduction of butadiene can make for something that is nominally ABS but really is closer to SAN, so less or no free butadiene and less or no free styrene, as butadiene has been shown to inhibit styrene polymerisation. So i have seen ABS samples with vastly different mechanical properties.

    Two types of bearing will be offered: one has a 'split-race' to allow rapid assembly/disassembly, the other has a 'gated race' for a seamless outer race.
    They consist of an inner race, and outer race and bit of filament to act as the actual bearing.
    Kind of like a 4-point bearing, but a piece of smooth filament instead of rolling balls...
    Printables will be hosting; look for "AX Hard Suit bearings" some time after 11/25/2022.

    Careful wearing gloves and using rotating equipment like a drill. If a thread or loose part of the glove gets caught on the chuck, it will wrap up almost instantly and you may have a broken finger, or worse, before you even realize what happened.

      Wearing gloves around quickly rotating machinery is serious stuff. A hand held battery drill might not be as dangerous as a lathe, but why risk your fingers when you work with your hands?

    What about metal BBs? Might be a good alternative to the plastic airsoft rounds.

    If you added a spacer/seperator like in sealed cartridge bearings, it might have taken some slop out of the airsoft design and provided longer life.

    Usually, the gears sit between an inner sun gear and an outer ring gear. There is no carrier or shaft on the planet gears they are solid - the herringbone gear pattern stops them from slipping out, and the gears don't touch one another.

    Good video. I am looking for a Pawl/Riving option or design that a sphere is what is rotating instead of the wheels around it., a pawl sphere if you will. Any chance you know anything like this?
    Also be careful using gloves when you're using anything that is rotating. cheers.

    For bearings, use grease, not WD-40... the grease amount is an important factor, too.

    So I am trying to have something made where the object stays still in the center and a camera moves around that, can you design something like that to print, I think it will probably use a bearing in the center and screw to platform so the outside of the bearing can be apart of whatever the camera is mounted to

    Great video . I would also suggest to get a more accurate test you should have/build a stand to hold the bearing and drill so you are not putting an unwanted (and inconsistent) axial load on the bearings. Great content.

    I think bb bullets are PLA that is why they wear out. What if you use grease instead of just wd40? It could have worked just fine i guess?

    Just to let you know, sprockets made of 100% INFILL PLA are stronger than 100% INFILL ABS. You should lube them with PTFE lube, its going to help dissipating heat.
    Thank me later.

      @@LetsPrintYT This test is not conclusive. None of the results are good. WD40 is not a lubricant and you didn't grease gears. But I do like your videos, I just think you messed up on this one and it's sad as this was an interesting test.

    ABS should not be used for bearings and bushings because of its low abrasion resistance. It is my experience. I use some PETG bushings in my printer :D

  • @GoingtoHecq
    @GoingtoHecq 3 года назад

    The gear bearing isn't itself that much of a bearing. It's relying on the bolts, and I feel like those fill the role of bearings and take it away from the gear.
    Also, as others have said, wd 40 is not a lubricant. For this plastic it'd be best to use Teflon grease.

    • @Gromic2k

      WD-40 also makes PTFE oil thats also called WD-40. That's probably what he used
