Tutorial: How to Model and Test the Automotive Differential in Blender

[@lookatthisvidsandfun]

"But first let's test the gears, if they work", he said! Freaking awesome!

[@shimdidlys2343]

Incredible. I wish I could like this more than once.

We do accept donations at our web site ;-)

[@TMZStreetWorkout]

very nice, thanks you. Used Bevel Gear Calculator for my personal project. This is much better than using gear add-on build in to Blender

[@Olav3D]

How much time does it take to add the robot voice to the tutorial?

[@marshmallow_fellow]

less time then actually recording a voice over.

[@trystonkincannon8320]

Yeah, I think that is what makes it so hard to follow. It talks so slow, and when it talks fast you'r not sure if it said x or z or ever b. I realy had a hard time following this tutorial but it's the only one I can find.

[@tristanw.4337]

Can you guys do a tutorial on a torsion differential?

[@abrahamwondafrash7549]

A very helpful tutorial! and thanks for the models!

[@AntonRiab]

You do great work. Can you make video, how to make in blender model of Recirculating roller screws. KZbin have SKF sample, but it does not have any math, forces(when it's work) and faq how to do model.

[@ryannguyen3494]

Hi, I’m stuck at 10:04, I believe I’ve done everything right up to that point, but my side gear’s first step rotates such that the teeth of the side gear and the teeth of the spider gear are overlapping and so it just stays there and wiggles. Do you or does anyone know why and how to fix that?

[@euanclouston1841]

I had this issue I had added a back to the gears and it didn't like it. Also check your normals, rotation and scale.

[@mrmentoracademy]

Kindly make a tutorial on animation of differential gear using driver in blender

[@tarun__nagle]

I am having bridge edge loop issue while making the gears. please give me any solution about it

[@SehxualPanda]

I was having problems too, but i got it working. send me a Private Message and I will help you out.

[@yeinierferras2721]

Excellent, thanks a lot by your work.

[@tarun__nagle]

Thank You sir

[@linuxdevice2718]

When I add the Side Hinge 2 and and Side 2 the animation now only works for a limited number of frames, around 50...then it locks up. Is there a way to debug this? Is it just a matter of randomly trying things, e.g., more subdivisions? How do I know what it is causing the lockup?

[@ajaysinghbisht8290]

Pls sir make unidirectional gear video

[@mtalhakhalid1679]

good job helped alot Thanks make Torsen Differential

[@Kimera_Alternate_Realities]

This is effing wonderful, this channel definitely deserves more subs. Subscribed for future tutorials and thank you for creating this.

Excelente trabajo.

[@ScubaDude1960]

The animation speeds up, then slows down and stops after 250 frames. How can I make it run longer and at a constant speed?

[@trystonkincannon8320]

You need to open a new "tab" (The little triangle lines in the corners) and make that tab a "Dope tab" by clicking the properties on that tab. You should see the animation speed and time represented by dotes and a line. Bring the dotes up or down to make a strait line. I hope this helped.

[@christopherstahler5376]

I have completed this tutorial and everything is working, however everything is spinning very slowly. How can I speed up the gear rotations?

[@OTVinta3d]

You can increase the speed of the motor constraint.

[@christopherstahler5376]

O.T. Vinta My apologies, but I’m still fairly knew to Blender and only been using it for 8 months now. Where in the constraint settings do I adjust the speed? I’m using v.2.9b. Also I tried as the tutorial mentioned to slow down the rotation of the gear inside the ring gear by increasing the mass, however the rotation only slowed down for about 15 frames, then it started rotating in sync with the ring gear again. The only way I was able to “fix” it was to lock the rotation in the properties panel preventing it from rotating at all.

[@OTVinta3d]

At 25:52, the Target Velocity is 1 by default. Set it to a larger number such as 10.

[@christopherstahler5376]

O.T. Vinta Thank you.

[@thatonethattalksalot7656]

You can use graph editor to adjust speed as one way to adjust speed.

[@tobiaskarl4939]

ohhh ... I can't download blend file. 404 - File or directory not found.The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.

[@OTVinta3d]

Fixed.

[@tobiaskarl4939]

Very nice. Thank you ! :-)

[@trystonkincannon8320]

Anyone have a download link for this, there is so much math involved where It seams unnecessary and I have never used python before. I want to get better at molding before I attempt something like this

[@trystonkincannon8320]

I did everything correctly but it still will not work, the gears come out strange and they will not line up for the spider gears HELP!!!! I am getting frustrated to the point of exhaustion I have been working on this since yesterday and can't figure out what is going wrong

[@trystonkincannon8320]

I got past the first part, took 2 more hours, but I am now having to do it again... Why can't he go through the steps one by one like in the beginning.

[@nightcoregovernorth1416]

Is the huge amount of vertices needed?

[@tomickyfm8925]

MAJIC

[@Nico-yo9bm]

the values @2,57 don't work in the www.otvinta.com/bevel.html. 5 = Facewidth value should not exceed 1/3 of the Cone distance . ok . 4,9=Error in Facewidth ok but 4,8=Error in Facewidth / 4,7=Error in Facewidth / 4,6=Error in Facewidth / 4,5=Error in Facewidth / 4,4=Error in Facewidth ... I have to decrease to 4 to have no problem

[@OTVinta3d]

You need to use a decimal point, not comma: 4.9, 4.8, etc.
