Worm Gear Casings
Three types of custom casings for worm gear and gears of various size.
There is a special Lego casing for a worm gear, which is nice and strong, but also large and only useful with a 24-teeth gear. To broaden the number of gears which can be encased along with the worm gear, I have developed three simple custom casings for a 8-teeth gear, 24-teeth gear and finally 40-teeth gear.

Hey Sariel. You build great stuff and have amazing ideas much more complex and cool than these, but I just wanted to thank you for posting these. Since you first posted them I’ve come back to this page time and time again and used one of these housings or a variation thereof in many creations or WIPs. Thanks!
@Sariel
it was typo, gear rack 🙂
@teh_obag
Well, what is a “great rack”?
@Sariel
why not? 🙁
@Luke
Nope.
Hi, do you have a casing for a great rack + worm gear???
@Jon Håvard
No, you can use 32039 just as well.
Is there any reason for why you used part 32013 instead of part 32039 at the 40t?
@Nate
Of course it would.
Hi Sariel. I was wondering if using the 8 teeth gear would increase speed. Please reply.
Thanks a lot for the worm casing, I’m using it to build a motorized fully automatic gun, using the power functions set.
The first casing gave me the perfect amont of torque for my technic truck. It is also more compact than Lego’s gear block
These are nice ideas for the worm gear, i just needed a casing like first one.
It helped me finishing my height-adjustable independent wheel suspension for my technic car.
You are doing great work, keep on going!!! 😀
nice idea. thank you.
also, is possible to use a similar arrangement for a gear rack winder.

in this example I combined both, but in a slight variation – notice how I swifted up the axis one stud (by adding an extra 8 gear).
it’s also possible to replace the 24 gear with two 8 gears, to achieve a lower profile
I like the first one becuase it fits all of the gear sizes
hmmmmmmmmmm…. you should use the things kind of like the ones shown, but with 2 stud long axles. red in a couple of sets….. for the 40 tooth gear. i hope i get a website. i’m protect-stuff-and-more on legomindstorms.com.
Hi! Thanks for sharing you work and ideas with other Lego fans.
Thanks for this idea because all the motorized parts of my 1st Trial Truck are based on it.

Well, I think you can reinforce it with liftarms. It is possible to build a stronger casing, but it would be much larger.
@Sariel
ahh, i see what you mean
so are there any stronger casings for 40t gears? – the one you’ve shown keeps wedging itself apart :/
@RjbsNXT
Nope, it won’t work with 40t gear. It’s too large to fit in.
you could infact use the first type shown for all of 8,24 and 40 tooth gears although i like the 3rd one aswell. good job 🙂
@Otto
Thank you. I use MLCad and LDraw. The last set I bought was 8297 some time ago, I focus almost exclusively on parts now.
What program you use for those pictures?
I allways wonder how you can imagine all these things… You are amazing builder. Do you buy sets or only bricks and motors and all those?
thanks your gear case has help me make prtotypse to motoris my hauler in drive.
to jest świetne! ta zębatka i ten ślimak czyli to urządzenie(które mi się bardzo podoba) może podnieść ramie od żurawia samojezdnego (8421) i nie tylko!!! 1000000/10
@Boris
The problem is mainly that it takes months or even a year to develop a really good TrTr vehicle, and I don’t have the time. I’ve built 37 creations in 2008, would you be happy if I just built a single truck instead?
@Sariel
thxx, I love all of your projects and most of your ideas, but I really don’t get one thing, why don’t you join the truck trial or participate in one. I saw that you have already built three trucks, but don’t see what’s the problem.
@Boris
LDView.
Ahh, can you please tell me what animation program you used?
Also this was really helpful.
@crawlerdude
Read FAQ.
where can i get worm gears? i looked on LEGO pick a brick but it didnt have any
Thanks, very useful in my snowcat.
Your little creations that you continue to create are what make your models a real thing of Beautiful Engineering.
@Sariel
How true!
This this is the Add-Sub I mentioned before, technic connectors being pushed apart by the load…

PS: Great Truck on technicbricks!
@lg008823
It looks interesting, but I think that it may come apart under a haevy load, just like the 40t gear casign I’ve shown here.
@Sariel
Here´s the deep link

I just noticed I did forget the 4x 3L axles to fix the whole thing together, good luck!
@lg008823
The file you linked to is not yet public. Try adding a direct link.
@djtermoz
Well something like that should do the job:

Helpful, but those are the easiest casings to build (40z+worm, 24z+worm, 8z+worm). Try to add some ideas for 16z+worm. That would be really helpful.
great aides! one remark to the casing with the 40-tooth gear. When the force on the wormgear gets too much, it might push the casing apart. The other two are held together with by liftarms.
I experienced this when I build a pretty flat add/sub for the 8294, I used the same technique but unfortunately the forces pushed it apart
very helpful
