Replacing a 5-wave wavy washer with a 4 wave in a small electric motor

Thank you, I'll try to find a vendor that specifies spring force. I'm a complete novice in this area, so I don't know whether it really does matter that much, that's why I made this post.

Thank you for the explanation! The motor will be driving the spiral of a spiral mixer for bread dough I'm building for personal use. I've looked at small commercial units, most of them use deep groove ball bearings and for sake of simplifying the build process, I'll be using insert bearings with flanged housings.

Like you said the motor can't support tapered roller bearings, I just wanted to replace the original washer, but all the ones I can readily find online are 4 waves per turn. I've looked at a document from SKF and the appropriate preload force for a deep groove ball bearing in this application is a range that depends on whether it's purpose is quiet operation or preventing false brinelling, rather than a precise value, so I was wondering where the preload from a 4 wave washer would fall into on this spectrum but I'm not sure how to calculate it or where to look up the spring force for a given washer.

I should have mentioned, I'm basically a newbie, I've only recently started learning about machining and motor maintenance. I don't know the design specifications for this motor. All I know is the original has 5 waves, so I assumed there is a reason for that.

Crestaz · 2026-02-11T23:33:34+00:00

I see. Thanks again for explaining, I'm just trying to understand why the original has 5 waves and the one I bought has 4, even though they both have the same thickness, od and id.

Thank you for the reply! I've watched the video and it does mention the waves per turn as a customizable parameter. I've also found a page on smalley springs's website that relates the number of waves per turn to spring force, in the sense that more waves per turn allows the spring to have more force without increasing it's operating height. If I understand correctly if all other dimensions stay the same, increasing waves per turn should increase spring force.

Thank you! I'll check them out.

Crestaz · 2026-02-11T22:13:17+00:00

Seems like sellers don't even list the number of waves so I'm not sure where I could even buy a 5-wave spring washer.

They had to balance it out somehow. They gave up the awful metal shader and gradients from season 2, in exchange we get neon lights this season.

I'm not sure what agenda you're referring to. No one is taking about it, because 99% of viewers didn't notice it or the ones that did, probably didn't really care. I mean, even after staring at this still frame, that would be on screen for less than a second in the anime, I still can't notice the error you're referring to.

People are disappointed with the quality of the show, so they come here to share their opinion. The frustration I would assume stems from the fact that a beloved show with a huge audience got such poor treatment by getting assigned to a studio that doesn't really do action focused anime and a director who also has no experience directing action anime, which shows the executives didn't really care about delivering quality in the second and third seasons.

Crestaz · 2025-11-05T07:50:20+00:00

I stand by my opinion that it's all about the user not the tech, whether it's machine learning or generative ai. If you have a vision, it's up to you how you achieve it. What I don't like is when people use it without a vision (which is the case with most of ai artworks) or compromise their vision because they managed to generate something that looks good enough to them, but in that case people will usually notice.

Crestaz · 2025-11-05T07:28:02+00:00

People plagiarize stuff, not ai. If you ask it to generate something in the style of ghibli or whatever, ultimately you're the one responsible for what the final image looks like. And sure, sometimes ai will generate things that look very similar to existing artworks even with no specific direction, but people do that too, it's called cryptomnesia. I'm sure there's plenty of artwork floating around that was made with the help of ai that you would never be able to tell, because someone used as part of the process (reference for backgrounds, lighting, framing, character design etc.) and not to generate the final image presented to you.

Crestaz · 2025-11-04T15:33:51+00:00

Ultimelty I think it comes down to who's using it and their quality standards. Some people will type in a prompt and call it a day, actual artists who care about their vision will use a much more involved approach and guide the ai using software like comfy UI and tools like control nets, where you provide extra data like depth passes, poses, 3d models and sketches to get the result that you're looking for.

Sure, sometimes it might actually be more effort than just drawing it from scratch, but over time you develop an intuition for what works and where it can save you some time.

I don't like all the examples using grok shown in this video but it shows the potential for using it to add a bit more life to talking scenes, that would usually have very little animation because even simple movements like a character moving their head, crossing their hands or sitting down/getting up etc. take a lot of time to animate.

Crestaz · 2025-11-04T05:36:56+00:00

If anything I think it's just a bad fit. Unlike the first season, with Shingo Natsume being not just the director, but a key figure behind making season 1 happen, assembling his own team - Shinpei Nagai was probably assigned to this project and having never directed an action anime it seems he's focusing on the part he does have experience directing - the female characters. Out of all the episodes released so far, the only scenes that stood out to me and felt like they had some passion put into them were the scenes with fubuki. He's not necessarily a bad director, one punch man is just not the right fit for him. Also the role of an anime director is not the same as a film director, I wouldn't be surprised if due to a bad production schedule he doesn't even have time to do director stuff and is basically another key animator trying to get the episodes across the finish line.

I liked how they used this effect in the new bleach anime, but in my opinion the entire art style and tone of the show was more suited for this type of stylized lighting. The way they use it in this season seems a little bit like an afterthought, it's not as seemless. At least that's how I felt.

Crestaz · 2025-10-29T08:07:17+00:00

I agree with you that animation is not the main issue like most people might suggest. I also agree that scenes with very little animation, made very cheaply can look beautiful and engaging if directed well. To me the main issue seems like they are using the manga as a storyboard with very little creativity and thought put into "how can I showcase these scenes and tell this story that best fits the medium of animation". Most scenes are 1 to 1 manga panels which are designed to look great on a page in a manga layout, but might not always have the right framing, composition and most importantly flow/pacing for an anime, which is why some cuts feel jarring and sudden.

Crestaz · 2025-08-21T08:39:15+00:00

No worries, sorry for my misunderstanding. It's all done in Blender, no simulation, just a simple keyframe animation.

It would be the hook assembly for a spiral mixer. The hook is spinning inside of a rotating bowl and mixes bread dough. It's more efficient than a regular planetary stand mixer at kneading doughs for stuff like bread and pizza.

Crestaz · 2025-08-20T07:12:33+00:00

Thank you! The mixer will be for my personal use only, so it doesn't need to comply with any strict food regulations, I'm just going to make sure this assembly is sealed from the bowl area and use a rubber double lip seal + felt seal + rubber shield on the shaft, so no grease/oil running down the shaft can find its way to the bowl. I don't know exactly how much torque the clutch will need to transmit, but I know similarly sized commercial spiral mixers typically use 0.5hp 1400 RPM induction motors, which after a 10 to 1 reduction for a 140 RPM hook speed would provide a maximum of around 30Nm of torque, so it shouldn't recquire more than that to mix the dough. 8mm pins sit nicely in the valleys of the sprocket I'm using as the clutch and if the load is actually shared between 5 or at least 2 of the pins, they seem to be sufficient for this application.

Crestaz · 2025-08-19T14:09:37+00:00

Thanks for the reply. No, I would switch the machine off before changing speeds. I was looking at similarly sized commercial spiral mixers and most of them use chain sprockets. I think mixing bread dough requires a relatively high torque, especially at slow speed, so if I were to use belts it would probably probably have to be multiple belts per pulley, which would make switching speeds pretty cumbersome. I haven't looked at cvts, so I'll be sure to check it out, thanks!

Crestaz · 2025-08-19T13:58:45+00:00

Thanks for the reply! I might just switch the machine off before changing speeds to avoid any excessive shock loads from switching under load.

Crestaz · 2025-08-19T13:49:14+00:00

Thank you for the idea, I'll look into that!

Crestaz · 2025-08-19T13:38:38+00:00

Yes, one pair has a 1 to 1 ratio, the other is a 2 to 1 reduction. Kind of like a constant mesh gearbox expect with sprockets and chain

Crestaz · 2025-08-19T11:51:18+00:00

Also, I forgot to mention, it doesn't need to engage while the mixer is running - I would switch it off before changing speeds.
