3D printed high torque servo/gearbox version 2

This servo/gearbox is the new and improved version of my original gearbox design (video: • 3D-printed high torque... ). I also made a shredder using this gearbox (video: • 3D-printed shredder ). The original one had a gear ratio of 30:1 and the speed of the output shaft was about 715 RPM which made it difficult to tune in the right PID parameters. This new version has a gear ratio of about 162:1 which lowers the speed and increases the torque.
I choose to go for double helical gears on this one because they produce a lot less noice than regular spur gears and the forces on the teeth are transferred more gradually. The gears rotate around a 6mm stainless steel shaft which is lubricated with bearing grease. Ideally all the gears should have some bearings, this is being considered for the next moment. Unlike my previous design I used 2 20mm bearings to support the output shaft.
The servo uses a 775 36V 9000rpm brushed DC-motor which is driven by my Universal Morion Controller (UMC)(video can be found here: • Universal Motion Contr... ). The stall torque theoretically is about 297kg*cm, I was able to test the servo to a torque of about 132kg*cm. During testing none of the gears broke, they were all printed in PLA. The weak link in this design however where the mounting tabs and the bevel gears used in the first stage on the motor shaft. These 2 gears tend to slip under high loads ,like when i tried to pull the car forwards with it's handbrake on, but this didn't occur when i performed the test where it pulled 132kg*cm of torque so it should be fine to at least this torque rating.

It appears a lot of people seem to think that the part in the video where i pull the car forwards is fake, which is understandable but not true. Pulling a car forwards on a flat floor really doesn’t require that much force, maybe 25-50kg max. Using a shaft with a radius of 1 cm equals to a torque of about (max) 50kg*cm required to pull the car forwards. The third test where i was able to reach a torque of about 132kg*cm was actually a lot harder but obviously seemed a lot easier because you’re “only” lifting 22kg at 6cm (132kg*cm) instead of pulling a big heavy car on wheels where you actually only require 50kg (max) at 1cm (50kg*cm).

@@BrianBrocken it might also be nice to convert your torque numbers to Nm (weight*9.81/length in meters)

@TheBPJo 3 года назад

you can easily calculate the necessary force with F = m*g and F_r=F*R with R= rolling Resistance of Tire on concrete. F_necessary needs to be higher than F_r , so that the car moves. m = 1500 kg (ford focus) , g=9,81m/s² , R = 0,01 --> F_necessary > 147,15 N . With a 6 cm radius, the necessary torque is about 9 Nm (6.64 ft-lb). and that is not that much.

While it performs a function, it still takes a lot of time to design, breaks, redesign, breaks, redesign, along with sanding, usually need to reinforce with metal axles, real bearings, and in the end, after days of work, still doesn't outperform something you could buy on Amazon very cheap and get it next day. It's still fun, and satisfying...but can be frustrating. I spent months designing and 3d printing custom oraginzers, shelving, tool holders, etc for my work van....and one day my 4 year old daughter left the side door open and only 1 afternoon of direct sunlight ruined everything. Even though it was supposed high temperature resistance filament, everything warped enough where it either didn't work right anymore, or just looked bad enough I removed it.

Here are some answers to frequently asked questions. Where can I find the stl-files, schematics, parts lists and more info about this project? - You can find more info on my hackaday page: hackaday.io/project/173854-3d-printed-high-torque-servogearbox-version-2 What software do I use to design all the parts? - The software I use to design all my projects is Autodesk Fusion 360, which is free for students and startups that make less than 100K per year. What plugins did I use to create the double helical and bevel gears in the servo? I used these 2 plugins, one is 40 dollars but well worth it's money: - apps.autodesk.com/FUSION/en/Detail/Index?id=2427789559362467821&appLang=en&os=Win64 - apps.autodesk.com/FUSION/en/Detail/Index?id=9029586664984391977&appLang=en&os=Win64 Why did I use double helical gears in this servo? - I choose to go for double helical gears on this one because they produce a lot less noice than regular spur gears and the forces on the teeth are transferred more gradually. What is the reduction ratio of the gearbox? - About 162:1 What is the speed of the output shaft? - Around 60-70RPM What is the torque of this servo? -Theoretically around 297kg*cm, practically around 132kg/cm (due to the limits of the plastic being used). What material is this thing made of? - All the parts were printed using regular PLA, link: www.banggood.com/Creality-3D-White-or-Black-or-Yellow-or-Blue-or-Red-1KG-1_75mm-PLA-Filament-For-3D-Printer-p-1290153.html?p=E01411629100201406T1&custlinkid=926158 What kind of printers do I use? - I use an Anet E12 and a Reprapp Prusa I3. Shouldn't the torque be in kg*cm instead of kg/cm? - Yes this is a small mistake in the video. Why do I sometimes use the potentiometer and sometimes I don't throughout the video? - The potentiometer is being used when the position of the servo needs to be controlled using the UMC I made (04:55). For the pulling tests i just controlled the speed of the motor and removed the potentiometer so it functions as a normal gearbox and isn't limited to 180 or less degrees. 01:54 is this the national flag of Belgium? - Yes it is. Was this done on purpose? - No it was not. If you have any other questions or you want some more info about the questions above, feel free to ask them in the comments below. Have a nice day.

@YamenNazer 3 года назад

Wooow it is incredible that how this small motor can pull a car💜👌

@VikingAtLarge 3 года назад

For anyone else confused by the 'kg/cm' torque measurements: I *think* I'm convinced I converted it correctly to both SAE and SI units I think are more familiar: That's about 13 N*m, or 17 Lbf*ft, which isn't _insane_ considering the 80+ pounds most cars' lug nuts are torqued to. Just means you need a longer lever, though. Or a bigger gear reduction, though :)

@BrianBrocken 4 года назад

Ok thank you Dirk ;-)

@CarlosMendoza-md9rr 3 года назад

So a part is badly edited, ?? and the test results are not bad ???

@saleplains 3 года назад

i mean yes but also no lol, its the cross product of a force vector and a distance vector. kg is a unit of mass. the force in this case is the gravitational force acting on the mass. 1 newton is 1 (kg⋅m)/s^2. surface gravity here about 9.81m/s^2. the most typical torque unit being the newton⋅meter (N⋅m) so for the final 22kg test we get a peak torque of just shy of 13 N⋅m when the servo arm is parallel to the horizon. this is quite a good result. however the mistake is more understandable here because for some truly unknowable reason the actual manufacturers of hobby grade servos such as Spektrum (the maker of his remote) routinely incorrectly use kg⋅cm instead of either N⋅m or mN⋅m (milli newton meter). This likely stems from the fact that on many of these companies rate their product using the imperial system and then simply post a metric conversion and some dumb technical writer got confused. this is because while we think of pounds and kilograms as being imperial and metric counterparts they are actually entirely different properties. pounds are not a measure of mass but are treated as such in some contexts even though weight is a force and so pounds are a force unit. this is why the imperial standard torque unit is the foot⋅pound (ft⋅lb) so someone at the company with limited understanding just converted feet to meters and pounds to kilograms and called it a day. TL:DR excellent servo and excellent video and someone at spektrum needs a talking to thanks for sharing your work with us

Great video! I see you're using PWM for the motor, maybe change the PWM frequency to something like 30-40kHz so that it's outside the audible range? It can get a bit annoying

Yes some people have also recommended this to me, I’ll have a look into it.

Music was ok, it had an ironic undertone, since it contrasted to the video-content.

@baldeagle5297 3 года назад

@@BrianBrocken That's why I prefer no music in a video like this. It can usually only detract, it seldom enhances.

Worth mentioning those are usually called herringbone gears in the 3d printing community. Some early extruders used that type.

@BrianBrocken 4 года назад

You’re right but both terms are correct and can be used, it actually doesn’t matter that much. www.sciencedirect.com/topics/engineering/double-helical-gear

@luke2642 3 года назад

Winding a rope on an axle as a winch multiplies the torque enormously, the narrower the axle. You could probably pull the car with a single 10:1 reduction stage and some 2mm dyneema rope on a 6mm shaft, for example.
