I designed a compact 3d printable harmonic drive gearbox. ...Below is a video with an explanation Video: https://www.youtube.com/watch?v=9sv-3hSR8XQ

Strain wave gear 3D Model (Harmonic Drive) Model based on split circular spline for NEMA17 Stepper Motor with D-Cut axis. ... Static circular spline: 62 teeth Flex spline: 62 teeth Dynamic circular spline: 64 teeth Gear reduction ratio: 32:1 ...

Prototype of harmonic drive, used to drive a robotic arm.

harmonic drive i made, uses 7.9 mm steal ball bearings. ...make sure to split into parts before printing

This is a 3D printable version of a harmonic drive. Harmonic drives are mechanical gear systems that have some very nice properties such as no backlash, high gear ratios, and being able to hold their position without power :...

... in a wave form, almost moving like a serpent... it works rather strange and funny, but they are used in high tech gear applications. more info : http://en.wikipedia.org/wiki/Harmonic_drive animation on : http://www.youtube.com/watch?v=lstQwLbAG0g

This is a harmonic drive for a nema 17 stepper. You need a few parts to complete this. 4 M6 x 10 or 12mm long Button head cap screws. (wave generator) 4 x 606-2rs bearings (wave generator) 24 x M3 X 16mm Flat Head Cap Screws (at least 12) 4 x M3 X...

A harmonic drive is a very simple gear reducer that lends itself well to 3D printing. It uses a rigid outer gear and an inner flex spline. The flex spline has a few less teeth (typically 2 less) than the outer gear. You stretch the flex spline...

This is a tri-lobe harmonic drive (because why not ?) Here are the videos where I talk about it :https://www.youtube.com/watch?v=yehE7aFYUGUhttps://www.youtube.com/watch?v=ajxFor8MDcA Thing comes complete with its solidworks source. Also available on...

My goal was to implement the principle of the harmonic drive into a sturdy solid module that can ultimately be used for making a robotic arm. This is my first prototype, and it works quite nicely.http://youtu.be/D_neLbcW_BY The circular spline has 84...

It is a type of harmonic drive, which uses a flexible output ring to attain a high gear reduction. My design is unique (as far as I know) in that it also incorporates a planetary gearset for further reduction. Instead of a toothed belt for the...

https://youtu.be/xw7izhJbOHs working video modeled with Fusion 360 printed with PLA, Custom maido good for fidget! ... you will need -m3x8 bolts -m3 nuts -BBs

Print the rotor and the casing out of a hard plastic, and the spline cup out of a flexible one. IMPORTANT: this needs lubrication! I used a silicone oil, but mineral oil should work too. It doesn't take much. I haven't tried a dry lubricant like...

Since original harmonic drive gearings are too expensive for me (one costs about 600€) im trying to build my own version. Im using 6mm steel softair BBs for the flexible bearing inside of the gearing. I already printed an approx. model of the...

Harmonic drive mechanism for robotic head

Small compact 3d printed closed loop harmonic drive. The flex spline should be printed with flexible material for optimal performance but works with standard PLA at 100% infill. The harmonic drive has the option to mount a potentiometer/encoder which...

Print in different colour for best results.This harmonic drive consists of 3 parts, the outer ring, middle flexible gear, and inner wave generator (that is what a video called it, I still think this is magic).The outer ring has 38 teeth while the...

3d printable Harmonic Drive for Steeper Motor(Strain Wave Gearbox) with 1:25 reduction steeper dim-42*42mm steeper mounting pcd - 44mm

Simple telescope mount using two CSF-14 and two CSG25 harmonic drives. ...Uses Nema 23 stepper motors with encoders.A variety of gear reductions can be attained depending on the harmonic drive section.

Great for giga pano's or video. ...Two csf-11-30 harmonic drives and 2 nema 17 26:1 stepper motors. ...Use any controller that supports steppers.

There are two types of harmonic drive (STL and Fusion360 files), one only has 2 contact bearings but has adjustable tolerances, the other has a full set of 8 contact bearings but the tolerances must be modified in Fusion360. I used the one with two...

50:1 Strain wave gearbox (Harmonic Drive) This is my prototype for a harmonic drive. Based on my tests this design has minimal backlash and is backdrivable. It's a bit big for what it does, so I'll be revising it for a more compact design. You'll...

Lightweight telescope or camera mount. ...Uses two csf-11-30 harmonic drives. And two Nema 17 26:1 steppers Has a Pole Master polar alignment scope on it. ...Put on a wedge and gain a GEM or use as a ALT-AZ mount

This is a harmonic drive designed by a great youtuber called @3DprintedLife I recommend you checking him out. He put this design on Github but not on Thingiverse, since Github can be a little bit scary for some people I decided to put it on...

Harmonic drive ratio- 1:100 (can be increased)Spur gear ratio 1:5This combination has much higher efficiency than combination of worm gears and multiple spur gearsDepending on the assembly requirement 3 spur gears can be used instead of 2 to open up...

There also is the 25 tooth GT2 belt that would be very difficult to source as it is not a normally stocked size.If you don’t quite understand the mechanics behind a Harmonic Drive, I recommend watching this video, it does a great job explaining the...

I'm using it as the drive gear for a turntable for photogrammetry.Assembly is straightforward, I hope: put the servo in the motor cage (from the top, wires first: it's a tight fit and you need to be careful not to damage the wires on the cage); the...
