harmonic drives 3d models

For no particular reason I made some printable harmonic drives. I just wanted to try it out. I don't have an application in mind for them. As expected, they have a lot of friction and are nowhere near back-drivable. But they do have decent stiffness...

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

... 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

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 : http://en.wikipedia.org/wiki/Harmonic_drive Harmonic drives have an...

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...

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...

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...

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...

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...

It is build around 2 harmonic drives used for CNC and has a payload of approx. 10 kg. It can handle most modern Cinema cameras, can pan L / R 180 degrees and tilt +/_ 90 degrees (depending on the camera size). On this Facebook forum you can see the...

Harmonic drive mechanism for robotic head

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.

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

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.

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

The harmonic drive has the option to mount a potentiometer/encoder which makes the actuator closed loop and allows for precise position control. A simple PID controller can be implemented to go from open loop to closed loop. ... Feel free to message...

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...

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...
