[@wkf57]

I think it's commendable that you're exploring a screw drive machine. Without something else to compare to, it's difficult to determine weak points in the drive train. Like you said, those screws create a massive amount of torque or resistance for the rest of your parts. Good job and good luck if you choose to build another one.

[@DarthAnnoyance]

A mechanical drivetrain like that is going to have all sorts of forces lateral to the torque. My first inclination would have been to have a hydraulic motor directly mounted on each screw. That would make torque the only stress on your frame, and eliminate the chance of bending any axles. Heck, you could put one on each end of both screws with "armor cones" over the front two, and voila - double the torque!

[@REDNIC79]

+Darth Annoyance yeah you are very right!

[@apexmike849]

+Darth Annoyance I was thinking: "I would have used hydraulic motors directly, instead. See if anyone else said it.."; First comment! What did scare the shit out of me though, was what might happen if you fell off, or something got caught in those screws (or the open drive chains).

[@mazdalorean]

You have earned a thumbs up my friend . When I heard those chain skipping sounds I feared the worst. You have had the opportunity to drive something very few people ever will drive. Too bad it didn't hold up longer for you. I guess you'll get that lawn decoration after all. Remember , life is more interesting if you get off the couch and try something. Congrats for that. I can't wait to see what your next project will be. Thanks for the show. Joe

[@didasbigirimana60]

[@alexbruski1138]

What I see as the biggest problem is the force needed to turn the drive screws is also being exerted sideways on the transmission shaft that is providing the power. Solution: use a worm drive on the screw and then run the shaft up the arm and use bevel gears to get the power from the transmission output shaft. You could still use chain drive from the transmission if you used a double worm drive on the ends of the screws. Or you could just use a worm off of the transmission to the shaft which ends as a worm gear driving the screw. Probably would not want the screw drive in the mud though... might have to put a gear case around it to protect it. That would make it safer also... Really cool idea. Hope you get this solved!

[@getahanddown]

[@mbukukanyau]

+decoysk Yes, they actually need to have enough buoyancy to float the vehicle.

[@77Avadon77]

+kenya catholic Yes exactly, that's what I was thinking. They need to be like pontoons that way you have the buoyancy and stability needed to carry a much heavier drive.

[@srjohndeans5508]

[@joseffinklematter6256]

Dan Grecu what

[@johnassal5838]

That's awesome. I hope you kept with it. Those exposed chains and sprockets are an open invitation for stones and such to jam up the works though. Ideally a hydraulic solution or a sealed induction motor or maybe a repurposed power takeoff for each screw would be better. Maybe throw something in there to slip before stuff breaks then apply power on both ends of each pontoon with a taller screw thread so less contact area on harder surfaces makes it less likely to get locked. I don't think you'll ever be able to tackle an approach or departure angle that acute outside of deep sand or snow though. At least not unless you use four shorter pontoons that can move a bit independently of the frame and each other, maybe throw a shock and spring on each corner as well as a flexable Ujoint where the middle of each pontoon is now with a shock linking it to the frame. Otherwise you'll have to stick to relatively even ground with smooth grade transitions. Must be a pain to try and tow that thing on ground when it's broke down. Maybe include a couple skis/slats you can jack down to make recovery a little easier.

[@mrg9964]

[@ductape8214]

love the bison ornament

[@TriggeredWorkz]

thats a big moose eh?

[@kens97sto171]

I think the larger diameter pods will help. it should spread the weight and you won't sink in as deeply into things which is where the large amount of torque was used. with more surface area the vehicle should float across services more easily. one other thing I thought of rather than using chains and sprockets on the end of the pods, what about using a hydraulic drive unit at the end of it. it would be mechanically more simple you could have an engine with a hydraulic pump and then the hydraulic drive units. keep working on it it's an interesting design and certainly has advantages over wheeled and track vehicles. these things were used in Russia and other places get over terrain with no other vehicle could get to. good work on the mechanicals by the way. Always fun to see someone build something and try to make it work.

[@stevenking2980]

But bigger screws requires more torque, so that's harder on the trans.

[@dannysulyma1259]

Steven King But powering it by hydraulics would remove the transmission from the picture

[@kens97sto171]

Steven King Sure would. Maybe do some gear reduction after the transmission... To reduce the stress on the trans itself. Interesting and cool project for sure.

[@Mr69ireland]

kens97sto171 That's a damn good Idea!!!

[@johnh1001]

kens97sto171 Good Day kens97sto171 . This drive mechanism is is what I thought up about 20 yrs ago , it'sa very intriguing ; helicoidal drive , screw drew drive , spiral drive . Just like a mechanical "helicoil" I, m an aircraft technician since 1980 , I went through college for tool & die design and started out out in Military Turbine engine . Toronto , Ontario , Canada . When you're explaining an idea to engineers or tool & die makers it always works to make use of an example . Could you please extrapolate with this example of hydraulic drive in this application ? . Do you mean a torque converter drive ?

[@williams6550]

+luciano gianfiori That's what I was going to suggest as well.

[@Grumpy_old_Boot]

If you ever decide to try and make it hydrostatic, look at getting a pump and some drive motors from a skidsteer loader like a bobcat, or one of those small mini-excevators. Maybe find one that has a blown engine or something. If you add a bypass loop with a high pressure valve, you should avoid it blowing up on you too. Besides, with hydrostatic drives, you could also do neat stuff like roll sideways 'n' stuff. :)

[@REDNIC79]

Grumpy ol' Boot yeah i'm thinkin thats the best bet....seems hard to find a cheep wrecked one here, i've been lookin around though. sideways roll would be sweet! thanks for watchin

[@Grumpy_old_Boot]

REDNIC79 Quite welcome, always fun to see people's creations. Which ofcourse means I often end up in the russian part of youtube ... and *man*, they got some weird stuff over there! >_< Alternatively, you could make it into a tracked vehicle, that could be fun too.

dude all you gotta do is weld that casing . put a gear box on it with a larger gear reduction/displacement. you can have a 2hp engine and a massive gearbox to displace the torque!!!! it can become a goat with the proper gear ratio

[@cumminspower5531]

I would move the drive chain that turns the screws, to the middle of the tank. Half way exactly. Now the torque is distributed evenly front to back. It would make life on that rear bearing a little easier....lol. Good luck, friend. Keep at it.

Cool excavator on the legs! If there is such an excavator, then you do not need a screw drive vehicle. Make walker, please.

[@rc_action_]

Dude you own some weird but really cool equipment!!!

[@Femmpaws]

Interesting build the one thing that I think was the down fall was the course thread on the screws. If you were about half that it would have likely worked better. The most of the load is coming from trying to push the ground sideways not moving the thing forward.

[@REDNIC79]

Kriss Femmpaws yeah your are right in some ways for sure....although i still needed a way for the transmission to 'slip' in high load situations, such as a jammed screw. thanks for the input!

[@Femmpaws]

REDNIC79 Use a shear bolt like they use on a lot of farm equipment it's easier to replace than a jam screw. Go look at an old hay rake or bailer,

[@REDNIC79]

Kriss Femmpaws you are the first person to mention that idea. It so simple i cant believe it had not crossed my mind, hah, if i would have done that, im sure i could have saved it! Some times its so hard to not over think things, i get caught up in my own mind. Thanks, thats great stuff, so simple, so smart.

[@Femmpaws]

REDNIC79 one advantage I have is 45 years working on or building stuff so I have a good background. I would say make your pods about 4 feet longer and the helix pitch about half of what it was. By making it longer you will have room to put in failsafe in the system. I would look using belts for steering clutches and that would be your safety.

[@pravednik01]

REDNIC79 stvarno :) hahahahahaaaaaaaa very first person....hahahahaaaaaaaaaaaaaa it is serbian idea 1950's russian army very used this serbian idea.

[@RyanQuintanapolymath]

woa there that is a crazy contraption. I kind of figured we did not make vehicles with screws unless they were drills because we have to defeat the friction of the surfaces rubbing together which takes a lot of torque

[@RyanQuintanapolymath]

I bet you can keep going with the idea the only issue is that you have to get specially made thicker parts that can handle the torque. think huge mining drills and how thick the parts are basically you would be making a new tank like machine at the end of everything

[@wi11y1960]

Do it like a zero turn radius mower. Engine powers a hydraulic pump. Hydraulic pump drives two hydraulic motors (one each direct drive to the screws). You then have forward and reverse by moving which way the oil gets to each motor.

I used to do that kind of stuff. Had some really good ones not expecting it. And... had some bad ones, expecting easy good ones.

[@primallegacy4440]

next time you try, instead of putting the drive train at the very end you should put it in the middle of your screws. it will even out the weight and pull on the screws and give you more direct flow of your power.

[@egesajesse]

very cool stuff, love the rescue vehicle... very nimble too....

[@jimciancio9005]

What about running a hydraulic pump off the engine to 2 separate hydraulic motors on the pods? It would simplify things and you'll have better control without the need for brakes and your weak points of shafts, chains and sprockets. I understand that it's not a cheap gamble, but it's more forgiving and much easier to control with a 2 lever valve system. Having forward and reverse all run by hydraulics is just a better engineering aspect and independent drive motors running off a central pump would be best. I'd recommend a log splitter style 2 stage 16gpm or larger that way the pump won't overrun the engines power when your load changes aka for hills or pulling heavy loads. The 2 stage acts like an automatic transmission and will downshift to less flow more pressure under heavy loads and switch back on its own when you are just traveling on flat runs. IDK just a thought. I'm an engineer for a living, and if I were doing something like this, that would be the way I would have gone. I wish you the best of luck and would like to see it eventually work out for ya.

[@kumarmolligoda39]

It will work on absolutely level and hard ground only .When it gets bogged down it cannot haul itself up because the drive track is longitudinal

[@hashshashin000]

what's up with the hate? maybe it is impractical but this thing is amazing, and its something unique

[@REDNIC79]

+DAVE MCVEY yeah i think you are right, i hope :) thanks for taking the time to comment!

[@douglarue8485]

cool build! I'd vote for hydraulic drives on the back of each screw instead of chain/sprocket. Way cleaner, nothing for sticks and stones to jam. Hoping to see this going again. Good luck.

[@REDNIC79]

+Doug LaRue thanks! yeah, i know hydro is the way to go....i'm giving the chains one more chance though, just for fun :)

[@douglarue8485]

+REDNIC79 one thing I've learned over the years is that mechanical systems need a way to "flex" or "give" or else something will break. Hydraulics are nice in this regard because the fluid is like a spring and shock absorber. If doing chains, maybe look for a way to add a clutch or something which can give before things break. Fingers crossed your new drive system works so then you can get on with some suspension. :-) Good luck and looking forward to more videos.

[@mawage666]

Wow somebody has some money and time on their hands! I guess that's what you get when you're smart. I need to get learned! lol

[@hurleyinnh]

What if you attached a hydraulic pump to the motor and had a hydraulic motor for each tube spiral thing and ran it through some valving to control the speed of each side independently to steer and for speed control? That may eliminate so much mechanical stress on the frame and drive train and it would only have the force on what holds the hydraulic motor in place? I have no clue what I am talking about but would seem a lot simpler and reduces a lot of torque points down to a couple, and don't have to worry about mud and debris collecting in the chains causing problems/failures and further resistance for the motor and drive train components. Looks like some good and cool work you did putting it together, awesome project!!!! Thank you for sharing : )

[@REDNIC79]

+hurleyinnh yes i agree with you...but i just don't know how big of a motor i would need, and i don't know how i would calculate it. thanks for the input!

[@josepardo606]

[@cyberbotb]

this is the first time seeing the screw tractor, idont know if it was mentioned before, but what if the chain was connected on the middle part of the screw shaft instead of the rear. make some kind cutout in the middle. it will look like you have 4 short screw shaft instead of two long shafts.

[@antonnym214]

The 16-inchers should do much better. Best of luck, and hope to see the video when you're ready to deploy that.
