Modeling Blog Daily - Lego Planetary Gear DETAILS

[zakeunc]

lego actually makes two different ring (or hollow) gears ... one is in the turntables (like you have above; there are two varieties of them with the only difference being the mounting points) the other is actually a wheel from the halfire droid set - it is much larger and allows you to fit different sized gears inside. the turntable is a good piece to use, though I would recommend figuring out a way to put 3-planet gears around your sun gear; its possible and can handle much higher torques!

You could use a fly wheel for the automatic trans. Idk if that's what the govonor you're talking about is but it could work

@heychika112 One of these days I'm going to do it...

muhaha... glue the technic turntable & run a second motor off a train controller to the outside of the turntable and you get a variable transmission similar to the Power Split Device as found in a Toyota Prius (maybe) - see eahart[dot]com[slash]prius[sla­sh]psd for info & interactive demo

they make a piece you can PUT GEARS IN for a planetary gear for sets with pistons i might make a video of it.

I would definitly like to see that one!!! Bill

Bill you are a GENIUS! A GENIUS!I never would be able to make this .THIS is so cool it must have been the hardest thing you've ever made!Hope you enjoy building.

[modelingblogdaily]

Well thanks for the nice comments. I think the hardest thing I ever built is IN PROGRESS. I am taking this model as a basis and making a 3 SPEED AUTOMATIC TRANSMISSION... Stay Tuned... Bill

[azerrlight]

now fit your gearbox to it =D

[modelingblogdaily]

HA HA!!! Well that is an idea for sure!!! I think I am going to make this one into a 3 SPEED AUTOMATIC TRANSMISSION ... Bill

Bill, if you want to regulate the speed of the motor the lego shop at home site has a power regulator on sale for $20! Can't wait to see the transmission!

Thanks for the tip...  Bill
