Spiral Bevel Gears Drive

Hi everyone, my name is Morris. I’m from Taiwan.My English is poor.
The final version open pre-order. If you are interested, fill out the Google Form.


The Gears Drive Kit (one gearbox) is priced at 160usd + shipping Would take around 4~5 wks to make.

Recently I made a gearbox that uses spiral bevel gears to drive it
It is suitable for installing on Trucks of Calibre II and TorqueBoards and is compatible with 50XX or 63XX motors (8mm shaft) with ABEC wheel over 83mm

At first I used POM to make the shell for the gearbox.

Gears are also made using 3D printing

However, that effect is very unsatisfactory and the gear is damage 9227667fad9d34dfd95e4bd481e19d3a88ef94a5_2_690x335

I changed the material of the shell later and used aluminum to make the shell50bed43564a6c93982ba0bfa3ea6737e8424ff4f_2_666x500 c1856ab75974c3bf73f738a844391c469aa630e3_2_666x500

And change the gear to steel.

And colored the shell a little bit.

Finally, ask @sofu for permission to test this gearbox for me
She tested for me professionally and patiently, helping me find out all the problems in one fell swoop

There are also many suggestions to make the gearbox better.

Finally, She has been tested and improved many times before the gearbox can be finished smoothly.

@MorrisHsu maybe you should put a link to the interest form here?

Anyways here is the generations of testing I did… lotta evolution and amazing willingness to listen to feedback from Morris

How does it compare to other types of gear drives besides the shape and mounting style?

Is it viable inward mounted with 6374 motors?

Is it quiet? can the angle of the motor be made to point more upward? I’m full of interest.

I’ve not seen it ride but from the gear profile it will be louder. The obvious benefit is larger motors on a narrow truck. Also… rocket boosters right?

I’d hope they would be the same, because if ride quality, power transfer and all that stuff I don’t quite get is the same, then those are way cooler. But i was thinking more something along that than rockets. image

It’s pretty cool, personally I think the ratio is great since it’s 2:1, and it’s compact which other drives tend not to be, so you can run small wheels.

technically yes but i would recommend against it.

It’s about as quiet as any other drive after you grease and seal it. Same loudness as fatboy but more high pitched, and quieter than kaly/etoxx gear drive 1.0 (non helical)

They just look great and after the changes is fairly easy to install. Just gotta be meticulous with the mounting and careful with the hardware but that’s par for course
