A Custom differential inspired by Sariel's

[rocklego]

When I read the chapter describing custom differential in Sariel's book, trying to follow instructions to build it .

Unfortunately, I only had "two" Knob wheels.

Then I came up with a idea that is there possible to replace Knob wheels with double bevel g20t ?

That means I have to build a different frame for three double bevel g20t which the 5X7 studless frame can not house.

After trial and error of building process , I managed to build a frame that can enclose three double bevel g20t and connected it to a turntable .

This differential is going to take more space than Sariel's when actually put to use.

Here is a short video demonstration of this differential .

You can make it much smaller and stronger with knob gears.

I couldn't agree more.

It is good to discover potential capability of Lego.

You could try my 6 bevel custom diff for high torque applications... It is very strong (using 6 bevels in total), and has very smooth operation due to using normal gears rather than knob gears.

More pictures and .lxf file can be found here.

EDIT: Please take great care when inserting the "planet gears" as they have to be correctly aligned for the diff to rotate easily. It should have almost no resistance when correctly assembled.

Thanks Nazgarot for the reply.

You had inspired me on how to improve to make a sturdier and high torque differential.

Just found your entry and the great contribution you made on your moc page.

Thanks a million, can't wait to build each and every and try them out.

Just put your diff together it's so smooth, very impressive.
