I was hoping to take just a couple of days on this video, but in the end it was 10 or so. And therefore little progress on the actual EV project&#8230; Grrr!<\/p>\n\n\n\n<p>I started out with one intention but then realised the video didn&#8217;t make much sense. So I had to re-record a bunch of stuff and rejig things. It probably still doesn&#8217;t make much sense to anyone else, but at least it seems to hang together to me.<\/p>\n\n\n\n<p>This is another one of those update videos, but in the end, I know that just rambling on about what I&#8217;ve been up to isn&#8217;t very engaging. All stories should have a beginning, middle and an end. Initially, the video had none of that. YouTube videos also work best when you present a problem, demonstrate that problem and then provide a solution. What I ended up with didn&#8217;t quite hit that succinct mark, but it was a lot better than what I originally recorded. I also had a bunch of home stuff to attend to, and that didn&#8217;t help with timelines.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">The Video Link<\/h3>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<span class=\"embed-youtube\" style=\"text-align:center; display: block;\"><iframe loading=\"lazy\" class=\"youtube-player\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/6-T_nF5wXZA?version=3&#038;rel=1&#038;showsearch=0&#038;showinfo=1&#038;iv_load_policy=1&#038;fs=1&#038;hl=en-US&#038;autohide=2&#038;wmode=transparent\" allowfullscreen=\"true\" style=\"border:0;\" sandbox=\"allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox\"><\/iframe><\/span>\n<\/div><\/figure>\n\n\n\n<p>I wonder how long it&#8217;s going to take until someone points out the deliberate error on the video thumbnail. I only noticed after taking the picture (and way before uploading the video, in case you think I didn&#8217;t) but in the end it was the only way to make the thumbnail work&#8230; IMHO \ud83e\udd23\u00a0<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">So what&#8217;s the video about?<\/h3>\n\n\n\n<p>As you all know, I&#8217;d come to the conclusion that I needed a gearbox in my EV project and I couldn&#8217;t find one to fit in the car. That meant I had to commission a bespoke gearbox. And by gearbox I mean a single speed gear reduction box. For all sorts of reasons a planetary box made most sense and so that&#8217;s what I commissioned and got designed.<\/p>\n\n\n\n<p>At the end of the previous YouTube video I&#8217;d got the design completed and we were about the press the button on making a one-off sample\/prototype.&nbsp;<\/p>\n\n\n\n<p>But that&#8217;s a lot of money. So while the gearbox guys (Compact Orbital Gears) were looking at the manufacturing process, I decided to 3D print the design and make sure it all fitted together in the order they suggested and worked the way we hoped. It also meant I could test fit the splines on both ends, into the motor and the prop-shaft respectively.&nbsp;<\/p>\n\n\n\n<p>So in the video I cover a bit of the theory behind a fixed ring gear planetary gearset (there are lots of other ways you can arrange a planetary system to get different ratios and output directions) and to go over how that basic planetary setup translates into our project.<\/p>\n\n\n\n<p>And of course, because this is a YouTube video and a large percentage of the people watching won&#8217;t be up to date with the other videos, you also have to put in a the pre-amble about where we&#8217;ve got to and what happened before. Perhaps if the channel ever gets to have a sizeable returning watcher-base I can forego the updates and get to the meat of the video earlier.<\/p>\n\n\n\n<p>So eventually in the video I build up the test 3D print and show that all&#8217;s well. It all fits together and I&#8217;m satisfied that we won&#8217;t be throwing away a ton of aluminium and steel when we&#8217;ve fired up the lathes.&nbsp;<\/p>\n\n\n\n<p>There is one are of the build that might need to change and that didn&#8217;t get explored in the video, and that&#8217;s how the slow-speed assembly gets added to the high-speed side. The opening in the high-speed casing could do with being a couple of mm wider, I think, so the assembly order can be easier. It will work the way it&#8217;s designed at the moment, but I think it will be easier if the slow-speed side (bearings, muffs, output shaft, casing, planets, planet carrier straddle, pins etc) are all assembled together and then fed into the high speed assembly (gearbox rear plate, ring gear, sun input shaft) through the high speed casing rear aperture. The way the gearbox is designed at the moment the slow-speed assembly would only have the casing, muffs and bearings and the output shaft, planets, straddle etc would have to be inserted from the motor end after the high-speed casing was attached to the slow-speed casing.<\/p>\n\n\n\n<p>That probably alls sounds double dutch, but maybe there&#8217;ll be a video explaining all of that if we decide to change the design to the way I think would be easier.&nbsp;<\/p>\n\n\n\n<p>(In late news, we may also be changing the helical gears over to be straight cut&#8230; again. That&#8217;s a decision for this week, and there&#8217;ll be more about that in a future video if that&#8217;s what happens).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Video Production<\/h3>\n\n\n\n<p style=\"text-align: right;\">As usual this was a Final Cut Pro, Motion, Fusion 360 and Blender thing. I also use a lot of Screen Studio these days to do all my screen recording. It&#8217;s completely changed the way I explain stuff, and allows me to talk while I&#8217;m clicking on a screen to demonstrate something. Previously I&#8217;d have set up a Blender animation and then spent days fiddling with timing and voice-overs. Screen Studio allows me to cut all that out and be more natural&#8230; and a lot faster to get a video done.\u00a0<\/p>\n<p>On the Blender side of things&#8230; I got diverted again there too. The animation in Fusion 360 just can&#8217;t deliver on anything other than a simple setup. So I ended up modelling the simplified planetary gearset in Fusion and then exporting it as a USDZ and then into Blender. It then needed to be set up with &#8220;drivers&#8221; to animate the various gears based on the rotation of the sun. And because I am easily distracted, this all took a couple of days rather than me just putting up the sloppy output I could have taken from Fusion. But in the end the gears animations are soooo much better for the effort I put in. It&#8217;s a good job I half know what I&#8217;m doing in Blender now. And the USDZ workflow it pretty good now between the two apps, I just wish hierarchy was preserver and I didn&#8217;t have to go through all the parenting of all the sub-components to the different assemblies. If I were sensible then I wouldn&#8217;t entertain the following notion, but it wouldn&#8217;t be half a bad idea to find some way of automating that process.<\/p>\n<p>What did work well in Blender was using different scenes to do all the various animations. I could set up scene frame ranges per scene to do each bit of the animation (one rotation of the carrier) and then dump out those clips as ProRes with alpha. I had all the components of the simple gears and the production set all configured with parenting and Collections. Then one animation timeline animated all the rotations and transitions between different views. Finally each collection&#8217;s visibility was turned on and off per scene so I could get different clips of different things i.e. where are transition rotated the camera angle and changed opacity, I could do all of that with different scenes.<\/p>\n<p>Once I had the single carrier rotation and transition clips into Final Cut Pro I could repeat each clip as many times as I wanted to set the clips timing to my voice-overs. I could probably do all of this in Blender&#8217;s video sequencer, but that&#8217;s not where I do my final edit and I don&#8217;t need to be dodging between Blender and FCP all the time when I want to adjust the timing by a frame or two. The workflow I came up with worked pretty well and allowed my to do a bunch of camera moves and opacity changes all while allowing the gears to rotate seamlessly (i.e. the gear sets don&#8217;t jump between different rotation angles when I change camera angles). I clearly have too much time on my hands! \ud83e\udd23\u00a0<\/p>\n<p>As for camera stuff. I do all my a-roll into a Canon R6 that feeds into a Rode Video Caster. There&#8217;s a 2TB drive connected to the Video Caster and I record the Canon footage in 1080p&#8230; &#8216;cos it&#8217;s much faster to do this than worry about 4K. It also means I can do a lot of the audio processing as I&#8217;m recording rather than spending ages applying noise-gates and equalisation in post. I can have that all set up in the Video Caster once and I can record the main a-roll once and any pickups so much faster that before I had all that set up.<\/p>\n<p>Other camera used were Osmo-Pocket 3 that I had set up just in front of my chest for the workbench shots. I also had a GoPro as second camera for the workbench, set to shoot top down.\u00a0<\/p>\n<p>In the end the footage I got from the Osmo was good, but the camera angle wasn&#8217;t great. And the GoPro output was really noisy &#8211; even though I had a ton of lighting in the office. I also found the difference between the chest area Osmo and the GoPro camera angles wasn&#8217;t enough. So cutting between the two wasn&#8217;t convincing, and just looked confusing. So, I re-recorded a few of the shots with a Canon R5 pointed at the 3\/4 angle and that gave a better difference in angles and was more realistic when I was trying to hide gaps in the footage.<\/p>\n<p>There were also panning shots where I used either the R5 or Osmo on a slider, mounted on a tripod, it&#8217;s so much easier to get a steady tracking shot on a slider than it is to hand hold anything &#8211; even when you shoot at high frame-rates and slow the footage down later.<\/p>\n<p>I also had to do a lot of post colour correction to get the different cameras to represent, for instance, the purple of the workbench top. It&#8217;s not perfect in the final video, but it&#8217;s a lot better than the different purple&#8217;s I got between the GoPro, Osmo and R5.\u00a0<\/p>\n<p>What else&#8230; audio was mainly through the Video Caster, but I also used DJI Mic 3&#8217;s at the workbench.<\/p>\n<p>That&#8217;s probably way too much detail. \ud83d\ude42\u00a0<\/p>\n<p>\u00a0<\/p>\n\n\n<h2>Video Chapters<\/h2>\n<ul>\n<li>[00:00] Start<\/li>\n<li>[00:19] Project Recap<\/li>\n<li>[01:05] Why do we need a Gearbox?<\/li>\n<li>[01:43] What exactly is this gearbox<\/li>\n<li>[02:01] Planetary gearbox basics<\/li>\n<li>[03:21] Helicoils and Brass Inserts<\/li>\n<li>[04:04] Gearbox Asembly<\/li>\n<li>[09:50] The prints that didn\u2019t make it<\/li>\n<li>[11:35] What else this week<\/li>\n<li>[12:34] Wrap up<\/li>\n<\/ul>\n<h2>Transcript<\/h2>\n<h3>Start<\/h3>\n<p>[00:00] Hi, I&#8217;m John Martin and welcome to another project 7 update video. In today&#8217;s episode of What&#8217;s John Bino for Engineering this time. We&#8217;re going to take another look at the gearbox I commissioned, and hopefully save some money, or at least save future Johnson money when we get into the manufacturing of this gearbox.<\/p>\n<h3>Project Recap<\/h3>\n<p>[00:22] Before we get into the gearbox, we better have a recap for all those people who haven&#8217;t seen these videos before, and frankly, I&#8217;ve got far better things to do than go and watch all the past videos. In this project, we&#8217;re taking an unloved 2012 Caterum 7 Super Sport SB and converting it into a shiny new electric vehicle. We&#8217;re taking out all the oily bits and inserting brand new electric drivetrain. So far, we&#8217;ve got the car road registered, MOTed, and stripped down so that we can take a look at what we&#8217;ve got.<\/p>\n<p>[00:50] We&#8217;ve then 3D scan the whole project. And we&#8217;re ready for space planning. I&#8217;ve bought a motor and inverter, Attraction DC-DC converter. And a bunch of other ancillaries that we&#8217;re going to use in the project.<\/p>\n<h3>Why do we need a Gearbox?<\/h3>\n<p>[01:06] Now, we need a gearbox for a couple of reasons. One of them is that it helped fill a gap between the motor and the differential. Meaning we could run the prop shaft at the full speed we needed. The 2nd reason was that we weren&#8217;t delivering on the full potential of our battery and propulsion system, and our dynamic spreadsheet was showing us that we had a really poor, not to 60 time a 13.7 seconds. But if we had a gearbox, We can bring that all the way down to 3.4 seconds and get some really good vehicle dynamics.<\/p>\n<p>[01:37] So a gearbox is going to be essential for what we need this car to do.<\/p>\n<h3>What exactly is this gearbox<\/h3>\n<p>[01:45] But before we get into the meat of this printed gearbox build, I&#8217;m going to take a couple of detours. Firstly, to make sure we&#8217;ve got some planetary gearset basic nail down. Then I&#8217;ll show you how that relates to the gearbox I&#8217;ve commissioned, Then I&#8217;ll go through the specs of the gearbox.<\/p>\n<h3>Planetary gearbox basics<\/h3>\n<p>[02:01] And finally, a quick detour into inserts. You&#8217;ll see what that&#8217;s all about when we get there.<\/p>\n<p>[02:09] There are many configurations of planetary gearing, but I&#8217;m only going to cover how we&#8217;ve used them in this project, and I&#8217;ll use a simplified model to demonstrate the principles. Firstly, we have an input sun gear that takes power from our motor. Then we have 3 planets orbiting the sun, sharing the torque from the motor out to a fixed ring gear. A carrier connects all the planets together and is where we take the output from this gearset. The general gear reduction equation for this arrangement is one plus ring gear teeth, divided by sun gear teeth.<\/p>\n<p>[02:42] And therefore, in this example, the speed reduction is 4.5 to one, which also follows that we have a torque increase of 4.5 to one as well. Applying that simple example now to our gearbox. We have a sun input shaft, 3 planets, a ring gear, and planet carrier, which is our output shaft. I&#8217;ll make the ring gear a bit see-through so we can see what&#8217;s going on. We call the motor side of things the high speed end, and fairly obviously, the output side is known as the low speed end.<\/p>\n<p>[03:10] Simple, really, but the devil is in the detailed loading and lifetime calculations. And that all leads us to a gearbox with the following specifications.<\/p>\n<h3>Helicoils and Brass Inserts<\/h3>\n<p>[03:20] You can pause and read through all of that at your leisure.<\/p>\n<p>[03:28] I&#8217;m now going to take a bit of a detour and explain about threads and inserts. When we&#8217;ve got something soft, like aluminum, or in this case, plastic for this test piece that I&#8217;ve printed out. The threads of a regular fixing are potentially going to pull out in the soft material. So there&#8217;s a few things we can do. Firstly, we can tap the thread of the plastic the way we would normally any sort of metal, but we run the risk that any load on this fixing is going to script the threads and pull it out.<\/p>\n<p>[04:01] The 2nd thing we can do, which is what we&#8217;ve done in<\/p>\n<h3>Gearbox Asembly<\/h3>\n<p>[04:05] the gearbox is that we can insert what&#8217;s known as a helicoil. Now, helicoil is a coil of wire that 1st of all gets tapped to a larger dimension, in this case, for an M5 fixing, we&#8217;ve got a M65.8 tap been run through, and that means we can take the helicoil with an insertion tool. We can place that into the thread. And that gives us more surface area for a fixing to be able to attach to. Another way we can do this is with heat inserts, and that&#8217;s the way I&#8217;ve done this on the plastic PLA printout that I&#8217;ve done of the gearbox, anywhere where there&#8217;s a fixing needs to go in.<\/p>\n<p>[04:49] I take a heat insert. Heat it up with a soldering iron and melt it into the plastic to give myself a better fixing. And now I&#8217;ve got another fixing for an M5 bolt. So there we have 3 ways of being able to fix into a material. The regular threaded hole being the most limiting option, the helicoil that we use for the gearbox in production and a heat insert that I use for my 3D printing.<\/p>\n<p>[05:25] When I left you last time, the gearbox was GA complete, with just a few of the cosmetics to get sorted out. But in order to try and save myself some money in the future, I wanted to 3D print the gearbox, assemble it, and make sure it will all go together the way I expect it. If it doesn&#8217;t, then it could cost me quite a bit of money in the future when we started cutting metal and things don&#8217;t work out the way we hoped.<\/p>\n<p>[05:46] So let&#8217;s go over to the workbench and see about getting this gearbox assembled. I&#8217;m going to start with the output. And what we&#8217;re going to do here is put a couple of the bearings on.<\/p>\n<p>[06:00] And then the casings, obviously, being 3D print makes a bit of noise because of the layer lines, this thing goes on, there&#8217;ll be bow rings that sit in here. Second bearing goes on there. And then a circlet goes on there.<\/p>\n<p>[06:22] Because these are 3D bearings and some of this tolerancing isn&#8217;t quite right on here. There we have that assembly sort of in place. What I&#8217;m going to do now is build up the carrier. So 1st off, we need the pins to go in.<\/p>\n<p>[06:48] And we have some spices.<\/p>\n<p>[06:52] And then&#8230;<\/p>\n<p>[06:57] Roller bearings. Another spacer. Then we can put the planets. On to their pins. And another space. And then we can put the Carrier on.<\/p>\n<p>[07:21] And there are circlips that I seem to have left somewhere else. lets go and find those. Here you go. Here&#8217;s the missing circlips left on my desk.<\/p>\n<p>[07:36] Okay, so that&#8217;s that assembly done. Let&#8217;s put some. Of its bolts in.<\/p>\n<p>[07:46] Hey, there we have. The Planet Assembly.<\/p>\n<p>[07:56] Okay, cheat again. Stick that in there. And that&#8217;s that low speed assembly put together. What I can do now is put the top casing on.<\/p>\n<p>[08:21] Let&#8217;s put some of this together now. So we have, This 3D printed race that I&#8217;ve done, the inner race sits on a tapered shaft here. So it doesn&#8217;t go on. It doesn&#8217;t go on that way. Goes on that way. This fits in.<\/p>\n<p>[08:46] And then there&#8217;s a pin that goes in to the back.<\/p>\n<p>[08:57] Next up, I&#8217;m going to attach the baffle.<\/p>\n<p>[09:10] Okay, next up. The ring. On here.<\/p>\n<p>[09:21] The way this sort of has to go together at the moment is that goes on here. Get the spacer right round, of course, and then its nut goes on here. This nut is to pre-attention the bearing. I don&#8217;t have the correct bearing here. I&#8217;m just using a cheap cylindrical bearing. So what I get is a cheap alternative. Now we can put, let&#8217;s get that out of the way. Then I can put the sun gear into the planets.<\/p>\n<h3>The prints that didn\u2019t make it<\/h3>\n<p>[09:55] And then we can put the There we go. And then we can just put the 3 bolts in here. Normally do this with this up between my knees. Which is a lot easier. Assuming the factory, they would have some sort of jig.<\/p>\n<p>[10:18] This would then, this would then be the gearbox assembly, and that would get attached to the motor with an adapter plate, is our cutaway motor assembled. Let&#8217;s give it a twirl.<\/p>\n<p>[10:35] It&#8217;s much quieter than the previous process we put together, because I&#8217;m using full bearings in here, and in the main positions, and also in the planet&#8217;s pins. So that&#8217;s all come together pretty well.<\/p>\n<p>[10:50] Here&#8217;s the support material I used to print the model. Uh, it&#8217;s not too bad, but uh, as you can see, the support material needs to be pulled off any print where there&#8217;s no overhang. The support holds it up off the print plate as the layers are printed in the 3D printer.<\/p>\n<p>[11:12] And here we have a mistake. This is a bunch of stuff that I printed, didn&#8217;t quite come out the way I wanted. And This one I decided I only print wanted to print half halfway through the print, realized I was printing half. Same with this one. I printed the whole thing out, took 9 hours, and in the end I realized, oh, we should have printed half of that.<\/p>\n<h3>What else this week<\/h3>\n<p>[11:33] This one got printed with no thread on here, so I couldn&#8217;t attach the pretensions, the bearing. These spaces, were a little bit too thick. They&#8217;re specifically tight in the model with the idea that different spaces get used when figuring that out in the assembly process. This was the associated nut that didn&#8217;t have a thread on the inside either, but also no threads for the grub screws. So that couldn&#8217;t get used. I only realized I needed those 2 to be threaded later on.<\/p>\n<p>[12:08] And finally, this carrier. I printed it out. It got to 99% and then the filament jammed. I came into the office to have a look at the printer. I thought, oh, it&#8217;s as I walked from the house, it should be 100% complete now. So I ripped it off the plate, only to realize that there was actually filament jam, and it hadn&#8217;t printed the final, couple of layers.<\/p>\n<h3>Wrap up<\/h3>\n<p>[12:33] Unfortunately, that meant that was scrapped. So there you go. Along with the support material. That was the wastage on this project. Okay, so that&#8217;s the story of the gearbox. There might be a few modifications. required, but nothing that&#8217;s going to be earth shattering. We&#8217;ll just have to see how that pans out when we start looking at the manufacturing a bit more.<\/p>\n<p>[12:58] So what else have I been up to this week? Well, for one thing, I&#8217;ve been looking at how the AC waveforms are going to be sent to the motor from the inverter. In the past, we&#8217;ve looked at this, and I&#8217;ve described them as being sinusoidal, but actually, they&#8217;re a modified sine wave, and in our motor, I think, this is a space spectrum modulation, which creates a waveform that&#8217;s a triangle wave, and assign what we&#8217;ve had it together. And I&#8217;ve been doing some reading up about that in one of my favorite books, AC motor control and electrical vehicle applications.<\/p>\n<p>[13:31] It&#8217;s a rip-roaring read that is essential for anybody looking at motor theory. In other news this week, I got a package delivered from Ali Express. I&#8217;d ordered a pre-wired connector for the vehicle control unit so that I don&#8217;t have to go and do all the wiring myself. We&#8217;ll have to see how well that&#8217;s been engineered, but for the moment, I&#8217;m hoping that&#8217;s going to save me quite a bit of time. That&#8217;s it for this week. I hope you enjoyed my shenanigans in putting that 3D print together, and I hope you learned a little bit on the way.<\/p>\n<p>[14:01] Please do like, comment, and subscribe to this video. does really help the channel.
