oldham coupler 3d models

An Oldham coupler is a method to transfer torque between two parallel but not collinear shafts at some distance(misalignment).

Oldham coupler very simple but very (very) functional just a piece just a screw (M4x25mm, in my case) just a T_nut (M4, in my case) just one nut - blind nut or similar - (M4, in my case) and last but not least: only a point of contact NOTE: the...

This is an oldham coupler intended to interface the X/Y axes of a mini mill to a stepper motor, but the general design principles can be applied to any interface where shafts might not be perfectly aligned. The one innovation i am "claiming" is using...

My rendition of an Oldham Coupling Link to Wikipedia page: https://en.wikipedia.org/wiki/Coupling#Oldham The joints have been modeled to machine tolerances if you elect to use them as such, otherwise all sliding and rotating joints will require...

Oldham Coupler for 5mm motor/8mmLeadscrew. ... Use 3mm screw to hold in place.

Oldham coupler for Geetech i3. Print as is, then glue the middle part together. I printed it separately to avoid supports and used ABS slurry to connect the two pieces together. ... Expect some sanding of the parts prior to assembly.

This Oldham Coupler mount allows the belt to pass through the aluminum extrusion without having the change the belt position by relocating the attachment holes from the bottom to the side of the aluminum extrusion. ... To attach both parts, either...

5x8 Oldham coupler for NEMA17 steppers on 8mm lead screws. Length 35mm, diameter 20mm (commercially available ones are 33x20mm). There is surprisingly very little play, and the assembly slides smoothly. Some action :...

Oldham coupler for CR10/Ender

Changed the top part to be straight as it was too far away from the frame for me to get a straight leadscrew

Printing this finally fixed the artifacts I was having on the surface of my 3D prints.. Slight misalignment / poor manufacturing of the lead screw will cause the whole gantry to wobble slightly.. This coupling allows the lead screw to wobble in both...

This is a remix of HAHNPV's oldham coupler for the HF 49911 mini mill. ... I added holes for 3mm nuts and expanded the holes for printing in ABS.

Oldham coupler for TEVO Tarantula Here's a remix of Doron Shalev's brilliant oldham coupler for the TEVO Tarantula. This device will help people get rid of the Z-wobbles. This is a part of my complete remake of Tevo's printer. The manual is...

... and 3 wheel mod on your tarantula you may have noticed that leadscrew is too close for and couplers. ...Well i have and needed something that is verry close to x axis 2040 extrusion, so i made this. its modified oldham coupler from tomfrajers design.

This is a remix of the tevo tarantula oldham coupler except this one uses 20 .177 airgun bb's as bearings. This coupler is 29.66mm square. The lead nut mounting was borrowed from the original thing. This was designed this so that it is as narrow as...

This is a remix of the tevo tarantula oldham coupler that uses 24 .177 airgun bb's as bearings. This coupler is 33.5mm square. The lead nut mounting was borrowed from the original thing, and redesigned this so that it is as narrow as possible and...

Doesn't need supports elsewhere (even in the mounting holes) I wasn't satisfied about the old square Oldham coupler so i designed this. ... It has 2mm play on X and Y and it allows angular play without impacting Z height __________ <small>...

So this is a remix of mala04's oldham coupler. Its fits together like so: A B C or C B A A&C are the same part. The main change was that I don't like sanding and neither does my nylon so I got rid of the outwards offset of...

Oldham couplers with ball bearings. Outside diameter 20mmOverall length 33mmAxle size 6mm. You can make it lager (Max 8mm) or smaller.Bearings 3x6x2.5mmOutside diameter 15mmOverall length 22 mmAxle size 6mm. ...You can make it smaller if you...

Just a generic coupler

you will need 8 x 623zz bearings 8 x (3mm x 10mm bolts and 3mm washers once the coupler is printed out I just used a 2.5mm drill to open up all holes for the 3mm bolts

For all details please read the description written for the original project: https://www.thingiverse.com/thing:2581521 This coupler eliminates all regular z bands (same height between two bands). If you still have some irregular bands then you have...

Hi, this is my version of the oldham coupler for my Tevo Tarantula with two z-axis. I made this version because I don't have enough room on my setup for other couplers. I printed the middle part with support. Top and bottom parts can be...

... Thank you very much to ndupont for his idea in doing 'Nema17 5x8 Oldham coupler' and to leave me free to publish freecad projects too! ... A little bit of delicate grease for plastic in between creates perfect joint with no friction and play

... methods but the most I could get was loose contact on one end and high friction on the other. So I designed an Oldham Coupler to be connected between the ball screws and the X-axis bracket. ...And if I say so myself it has worked amazingly well.

I ended up printing [Elzariant](https://www.thingiverse.com/Elzariant/about)'s very nice [Oldham coupler](https://www.thingiverse.com/thing:2039498) only to realize too late that the stabilizer for the lead screw didn't line up with thingirob's...

So this is a remix of mala04's oldham coupler. BUT! unlike my other coupler, this one is specifically for the ender 3. (this is all based off a model I found of the ender, please let me know if something needs to change...mine is still 1...

Stepper motor coupler - Disk portion for Oldham type coupler

This z-nut mount is based on the Oldham principle. I made it as thin as possible. It gives the z-nut freedom to move in the x and y direction, while keeping it in place when the z rod is turning. ... Completely removes z-wobble.
